Can ChatGPT Replace Human Clinical Coders? A Comparative Study in Otology Billing.

OBJECTIVE: Evaluate the utility of the large language model (LLM), ChatGPT, for the analysis of operative notes and the generation of Current Procedural Terminology (CPT) codes in comparison to human clinical coders. STUDY DESIGN: CPT billing codes assigned by ChatGPT were compared to existing billing data. Otology practice within a tertiary academic center. METHODS: About 191 operative notes from a single surgeon (9/2022-10/2023) were analyzed. ChatGPT-3.5 and 4 models were prompted for CPT codes based on operative notes. Assessment included determining exact and partial match rates, sensitivity and specificity for targeted procedures, and work Relative Value Units (wRVU) differences between ChatGPT-generated and human-assigned codes. RESULTS: ChatGPT-3.5 achieved exact matches in 22% of cases and partial matches in 32%, while ChatGPT-4 achieved 14% exact and 33% partial matches. When cochlear implantation (CI) was excluded, performance dropped significantly. For CI, ChatGPT-3.5 demonstrated a sensitivity of 94% and specificity of 90%, while ChatGPT-4 showed a sensitivity of 96% and specificity of 92%. In contrast, performance on cartilage grafting was poor, with sensitivities of 4.2% for ChatGPT-3.5 and 0% for ChatGPT-4. ChatGPT-3.5 and 4 showed moderate CPT code matching accuracy among themselves, with slight agreement to human coders. Both models tended to underbill for wRVUs compared to human coders, with significant differences in the values generated. CONCLUSION: This study assessed ChatGPT's effectiveness in automating CPT code assignment for otologic surgeries. While the models achieved high sensitivity values for assigning codes related to cochlear implantation, both models struggled with complex cases, failed to apply modifiers, and often assigned fewer wRVUs. The findings highlight ChatGPT's potential in medical billing but indicate a need for further refinement.

Cost-effective use of breast biopsy techniques in a Veterans health care system.

BACKGROUND: Breast health has become an increasingly important issue among the veteran population. Options for the evaluation of a breast mass or a suspicious mammographic finding include open surgical biopsy at the Veterans Affairs (VA) hospital or percutaneous image-guided biopsy at an affiliated academic institution. We examined the costs and trends in the use of surgical versus percutaneous image-guided biopsy procedures in this diagnostic algorithm. METHODS: A retrospective review was performed of 62 patients who presented to the VA General Surgery Clinic with a breast mass or abnormal mammogram from 2003 to 2005. The Massachusetts Utilization Multiprogramming System and the Decision Support System software packages were used to track costs of procedures, by Current Procedure Terminology code and date of service, performed at the affiliated academic institution and at the VA hospital. These data were analyzed and described using the R statistical computing environment. RESULTS: Forty-six patients were evaluated using open biopsy techniques in the VA operating room, including 8 incisional biopsies, 21 excisional biopsies, and 17 needle-localization excisional biopsies. Sixteen patients were evaluated using minimally invasive biopsies at the affiliated academic institution, including 3 ultrasound-guided cyst aspirations, 6 ultrasound-guided core biopsies/vacuum-assisted core biopsies, 10 stereotactic breast biopsies, and 1 fine-needle aspiration. The average cost to evaluate a breast mass or abnormal mammographic finding in the operating room was 4,368.00 dollars (SD, 2,586.00 dollars), with a median cost of 3,479.00 dollars. The average cost to evaluate a breast mass or mammographic abnormality using percutaneous image-guided procedures was 1,267.00 dollars (SD, 536.00 dollars), with a median of 1,239.00 dollars. From 2003 to 2005, the proportion of percutaneous biopsies increased from 13% to 48%, whereas the proportion of open biopsies decreased from 88% to 52%. CONCLUSIONS: Over a recent 3-year period, we observed a 3.8-fold increase in the use of percutaneous image-guided techniques for the evaluation of breast lesions in the VA Tennessee Valley Healthcare System. Diagnosis by percutaneous techniques allows planning for a definitive surgery if a lesion is malignant or possible avoidance of a surgical intervention if the lesion is benign. Our data show that the costs associated with open biopsy techniques exceed those associated with percutaneous biopsies. For VA hospitals with available resources, the option of image-guided percutaneous biopsy techniques is a cost-effective alternative to open surgical biopsy.

Representation of ophthalmology concepts by electronic systems: intercoder agreement among physicians using controlled terminologies.

OBJECTIVE: To assess intercoder agreement for ophthalmology concepts by 3 physician coders using 5 controlled terminologies (International Classification of Diseases 9, Clinical Modification [ICD9CM]; Current Procedural Terminology, fourth edition; Logical Observation Identifiers, Names, and Codes [LOINC]; Systematized Nomenclature of Medicine, Clinical Terms [SNOMED-CT]; and Medical Entities Dictionary). DESIGN: Noncomparative case series. PARTICIPANTS: Five complete ophthalmology case presentations selected from a publicly available journal. METHODS: Each case was parsed into discrete concepts. Electronic or paper browsers were used independently by 3 physician coders to assign a code for every concept in each terminology. A match score representing adequacy of assignment for each concept was assigned on a 3-point scale (0, no match; 1, partial match; 2, complete match). For every concept, the level of intercoder agreement was determined by 2 methods: (1) based on exact code matching with assignment of complete agreement when all coders assigned the same code, partial agreement when 2 coders assigned the same code, and no agreement when all coders assigned different codes, and (2) based on manual review for semantic equivalence of all assigned codes by an independent ophthalmologist to classify intercoder agreement for each concept as complete agreement, partial agreement, or no agreement. Subsequently, intercoder agreement was calculated in the same manner for the subset of concepts judged to have adequate coverage by each terminology, based on receiving a match score of 2 by at least 2 of the 3 coders. MAIN OUTCOME MEASURES: Intercoder agreement in each controlled terminology: complete, partial, or none. RESULTS: Cases were parsed into 242 unique concepts. When all concepts were analyzed by manual review, the proportion of complete intercoder agreement ranged from 12% (LOINC) to 44% (SNOMED-CT), and the difference in intercoder agreement between LOINC and all other terminologies was statistically significant (P<0.004). When only concepts with adequate terminology were analyzed by manual review, the proportion of complete intercoder agreement ranged from 33% (LOINC) to 64% (ICD9CM), and there were no statistically significant differences in intercoder agreement among any pairs of terminologies. CONCLUSIONS: The level of intercoder agreement for ophthalmic concepts in existing controlled medical terminologies is imperfect. Intercoder reproducibility is essential for accurate and consistent electronic representation of medical data.

Representation of ophthalmology concepts by electronic systems: adequacy of controlled medical terminologies.

OBJECTIVE: To assess the adequacy of 5 controlled medical terminologies (International Classification of Diseases 9, Clinical Modification [ICD9-CM]; Current Procedural Terminology 4 [CPT-4]; Systematized Nomenclature of Medicine, Clinical Terms [SNOMED-CT]; Logical Identifiers, Names, and Codes [LOINC]; Medical Entities Dictionary [MED]) for representing concepts in ophthalmology. DESIGN: Noncomparative case series. PARTICIPANTS: Twenty complete ophthalmology case presentations were sequentially selected from a publicly available ophthalmology journal. METHODS: Each of the 20 cases was parsed into discrete concepts, and each concept was classified along 2 axes: (1) diagnosis, finding, or procedure and (2) ophthalmic or medical concept. Electronic or paper browsers were used to assign a code for every concept in each of the 5 terminologies. Adequacy of assignment for each concept was scored on a 3-point scale. Findings from all 20 case presentations were combined and compared based on a coverage score, which was the average score for all concepts in that terminology. MAIN OUTCOME MEASURES: Adequacy of assignment for concepts in each terminology, based on a 3-point Likert scale (0, no match; 1, partial match; 2, complete match). RESULTS: Cases were parsed into 1603 concepts. SNOMED-CT had the highest mean overall coverage score (1.625+/-0.667), followed by MED (0.974+/-0.764), LOINC (0.781+/-0.929), ICD9-CM (0.280+/-0.619), and CPT-4 (0.082+/-0.337). SNOMED-CT also had higher coverage scores than any of the other terminologies for concepts in the diagnosis, finding, and procedure categories. Average coverage scores for ophthalmic concepts were lower than those for medical concepts. CONCLUSIONS: Controlled terminologies are required for electronic representation of ophthalmology data. SNOMED-CT had significantly higher content coverage than any other terminology in this study.

Basic terminology in obtaining reimbursement for pharmacists' cognitive services.

PURPOSE: A basic overview and definitions of commonly used billing and reimbursement terminology that pharmacists will need to know to obtain reimbursement for cognitive services are provided. SUMMARY: Currently, the profession of pharmacy has been gathering momentum in its efforts to seek and obtain reimbursement for cognitive services. However, there have been major barriers in seeking reimbursement, including the lack of understanding by third-party payers of the pharmacist's role in patient care and the pharmacist's in-depth knowledge of pharmacotherapy, the lack of appropriate billing codes for pharmacists' services, and the lack of detailed knowledge and understanding by pharmacy practitioners of nondistributive reimbursement mechanisms, processes, and terminology. The types of services provided are usually described by the American Medical Association's Current Procedural Terminology (CPT) codes for the face-to-face provision of patient care services by a pharmacist. As of January 1, 2006, pharmacists have been able to indicate the appropriate diagnosis code from the International Classification of Diseases, 9th Revision (ICD-9) (ICD-10 will replace the ICD-9 on October 1, 2007), and CPT code when billing under a major medical plan that recognizes the pharmacist as a patient care service provider. Understanding the billing and reimbursement terminology will aid pharmacist communication with third-party payers, Medicare, and Medicaid. A glossary of the most commonly encountered terms in billing and reimbursement procedures for cognitive services is provided. Also included are lists of Web-based reimbursement resources and references on reimbursement for cognitive services by the pharmacist. CONCLUSION: An understanding of terminology is important in receiving reimbursement for cognitive services.

Penetrating hepatic trauma in children: operating room or not?

Nonoperative management has become widely accepted as the standard of care for patients with blunt hepatic trauma. Recent studies among adults have supported the use of nonoperative management of selective penetrating wounds to the hepatic bed in stable patients. The therapeutic management of children with penetrating injuries to the hepatic bed were evaluated to ascertain whether nonoperative management was a reasonable consideration in their care. The database of the National Pediatric Trauma Registry (NPTR) was reviewed for the period 1985-1994. ICD-9 codes 864.00 to 864.10 were used to select injury site, diagnosis, and, combined with Current Procedural Terminology (CPT) code data, to ascertain therapeutic interventions. The NPTR is a compilation of data from 61 pediatric trauma centers, currently held at Tufts University. The charts of 29,000 children were reviewed; of these, 1,147 sustained hepatic injuries, 132 (12%) of whom had a penetrating injury. The mechanism of injury was gunshot wound in 100 patients (76%) and stab wound in 32 (24%). The mean age of the children who had a penetrating injury was 12.7 years (range, in utero to 19 years). Six children were managed nonoperatively (5%), and 20 (15%) had negative laparotomy findings. Overall, 106 children sustained additional injuries that required surgical repair. There were 50 hollow viscous injury repair, 19 diaphragmatic repairs, 5 nephrectomies, 4 splenectomies, 4 pancreatic resections, and 43 significant hepatic repairs. The overall mortality rate was 9.8% (13 deaths). Nine of these patients died within 24 hours of injury. These data indicate that penetrating injury to the hepatic bed in children is associated with a high percentage of other organ injuries that require surgical intervention. This seems to be in direct contrast with the findings for adults, for whom the hepatic mass appears protective because of its larger size. The close anatomic proximity of the organs in a child's abdomen appears to make surgical intervention necessary for the majority of children with penetrating injury to the hepatic bed, and indicates that this approach should remain the standard of care for pediatric patients.

The MCFONTZL classification system for soft-tissue injuries to the face.

A review of the literature and case records reflected a need for the development of a clinically applicable assessment scheme and classification system for soft-tissue laceration injuries to the face. Herein, a systematic approach for assessing facial lacerations is proposed based on location, depth of penetration, branching, directionality, size, presence of soft-tissue defect, and translation of such injuries into the current procedural terminology (CPT) code. Moreover, a new classification system for facial laceration injuries is presented that may serve as the basis for simplification of current billing codes. Prospective clinical application of this classification system may lead to standardization of facial injury assessment and improvement in the incomplete and inconsistent patient record. This system will establish a reliable database that may identify factors in soft-tissue injuries that contribute to poor aesthetic results or secondary functional deformities. These data will lead to the modification of established treatment plans.

Pattern recognition in health insurance claims databases.

Information in claims databases resides in data patterns rather than in data elements. Finding this information requires new terminology, a willingness to pose questions of form rather than specific hypotheses, and a quality control system that elevates the correctness of data relations above the validity of single facts. The language of claims data is a newspeak of CPT (Current Procedural Terminology), HCPCS (Health Care Financing Agency Common Procedure Coding System), ICD (International Classification of Disease), and NDC (National Drug Codes) for pharmaceutical codes. The techniques of pattern discovery are really ways of asking the data for classes of relations, and they vary in their reliance on external information. Sometimes, the question is entirely constrained by preceding factors. Other times we may recast the natural history of disease into a claims context and ask the data to give us the shape of disease evolution. We can use highly automated systems to evaluate the relations between prespecified factors, or empirical techniques to search out common relations that we have not specified in advance. Using massive data sets requires that quality control corresponds to the nature of the high-level information that we derive from large databases.

Development and evaluation of a charge capture program for long-term care providers.

OBJECTIVE: Clinicians often have difficulty determining the appropriate Current Procedural Terminology Evaluation and Management code to assign to the type and intensity of patient care they provide. The purpose of this study was to develop, implement, and evaluate a handheld charge capture program for use by providers in the long-term care setting. DESIGN: Using a pre-post study design, we compared the coding accuracy and user satisfaction of an established paper process with a handheld charge capture program created for this study by means of: (1) preimplementation and postimplementation assessment of coding accuracy, and (2) preimplementation and postimplementation clinician survey. SETTING: We studied an academic division of geriatric medicine. PARTICIPANTS: Participants consisted of six clinicians who currently spend at least 50% of their clinical time practicing in the long-term care setting. INTERVENTION: A handheld charge capture program to replace the current paper-based charge capture process was reviewed. RESULTS: Overall coding accuracy improved by approximately 20% when the handheld program was used instead of a paper coding process. The majority of clinicians found that the handheld program was more widely available, efficient, easier to use, and encouraged the participants to document more completely and accurately in the patient's medical record. CONCLUSION: A handheld billing and coding program used by clinicians who provide care for long-term care residents is not only feasible, but leads to an improvement in coding accuracy when compared with a paper process. In addition, clinician satisfaction toward the billing and coding processes improved with the use of the handheld program.

Catheter use is high even among hemodialysis patients with a fistula or graft.

At any given time, approximately 27% of patients in the United States (US) receive hemodialysis through a permanent catheter. However, this cross-sectional estimate may significantly underestimate the lifetime exposure of patients to hemodialysis catheters, and hence, to the excess risk of the adverse clinical events associated with catheter use. To further clarify catheter use in hemodialysis patients, we identified a cohort of fistula and graft patients in the US Renal Data System using Current Procedural Terminology (CPT) codes. Patients were included if their first hemodialysis was between 1 January 1996 and 31 December 2001, and Medicare was their primary payer. We identified permanent catheter insertions in these patients using CPT codes starting 6 months before their first hemodialysis session (or fistula or graft placement, if earlier), and ending 40 months afterward. Most patients (82%) were >65 years old, 57% were male, and 72% were white. The overall rate of permanent catheter insertions was 44 per 100 patient years, with 57% of patients having at least one catheter insertion. The percent of patients receiving a catheter was similar before (30%) and after (27%) the first fistula or graft placement. Cross-sectional analysis may significantly underestimate the lifetime risk of exposure to hemodialysis catheters. Because catheter use is common even in fistula and graft patients, measures used to prevent adverse events associated with catheter use are important in all patients regardless of current access type.

Cost-effectiveness analysis of unicompartmental knee arthroplasty as an alternative to total knee arthroplasty for unicompartmental osteoarthritis.

BACKGROUND: The purpose of this study was to compare the cost-effectiveness of unicompartmental knee arthroplasty as an alternative to total knee arthroplasty in patients with degenerative arthritis limited to either the medial or lateral compartment. METHODS: A decision model was created for the treatment of end-stage unicompartmental knee arthritis. A literature review was used to identify possible outcomes and their probabilities following treatment with either unicompartmental or total knee arthroplasty. Each outcome was weighted for quality of life with use of a utility factor, and effectiveness was expressed in units of quality-adjusted life years. Gross costs were estimated from Medicare reimbursement data for the relevant Current Procedural Terminology and Diagnosis-Related Group codes. RESULTS: Sensitivity analysis demonstrated that the cost-effectiveness of unicompartmental knee arthroplasty is dependent on the assumption that its durability and functional outcomes approach those of total knee arthroplasty. Specifically, it is necessary for the survival of unicompartmental implants to be within three to four years of the assumed survival of total knee implants for unicompartmental arthroplasty to remain a cost-effective alternative. Under these assumptions, the use of unicompartmental arthroplasty is a cost-effective choice as it results in incremental gains in effectiveness at a cost of less than US dollars 50,000 (in 1998 United States dollars) per quality-adjusted life year gained. CONCLUSIONS: This study supports unicompartmental knee arthroplasty as a cost-effective alternative for the treatment of unicompartmental arthritis when the durability and function of a unicompartmental replacement are assumed to be similar to those of a primary total knee replacement. This suggests that, with appropriate patient selection, the currently available literature supports unicompartmental arthroplasty as a cost-effective alternative to total knee arthroplasty. LEVEL OF EVIDENCE: Economic and decision analysis, Level II.

Measuring the quality of care for group A streptococcal pharyngitis in 5 US health plans.

BACKGROUND: There is a high degree of professional consensus that children diagnosed with pharyngitis should only receive antibiotics if they have a positive test for group A streptococcus (GAS). OBJECTIVES: To develop and test the validity of a quality of care performance measure that examines GAS testing rates in children diagnosed with pharyngitis and prescribed an antibiotic. DESIGN: The measure developed examines the annual rate of GAS testing in children aged 2 to 18 years with an episode of pharyngitis who were prescribed antibiotics. The measure was tested for feasibility of implementation and validity in 5 health plans in the United States. Health plan administrative data were used to identify episodes of pharyngitis using International Classification of Diseases, Ninth Revision (ICD-9) codes 462, 463, and 034.0. Pharmacy data (National Drug Codes) were used to determine if antibiotics were prescribed for the pharyngitis episode. Laboratory claims data (Current Procedural Terminology codes) were used to determine whether a GAS test was performed. Rates of GAS testing in children with pharyngitis who received antibiotics were calculated for each health plan. Medical record abstractions were performed on a random sample (n = 465) of cases to assess percent agreement with laboratory claims data for GAS testing. Sensitivity of the administrative data for accurately identifying when GAS tests were performed was also assessed. RESULTS: Of the 120 158 children aged 2 to 18 years who had at least 1 episode of pharyngitis during the measurement year, 51 172 (43%) received antibiotics. Group A streptococcal testing rates for patients who were prescribed antibiotics varied widely among the participating health plans (59%-83% of cases; P<.05). Percent agreement between administrative and medical records data for GAS tests was 86%. The sensitivity of the administrative data for accurately identifying when GAS tests were performed was 85%. CONCLUSIONS: This quality measure is feasible to implement at the health plan level and validly assesses GAS testing rates using administrative data. The participating health plans are not performing GAS tests as indicated by current expert practice guidelines in a substantial proportion of cases. Improvements in adhering to these guidelines are warranted given the current levels of antibiotic overuse and antibiotic resistance nationally.

Excision of head and neck basal cell carcinoma with a rapid, cross-sectional, frozen-section technique.

OBJECTIVES: To compare a rapid, cross-sectional frozen-section technique with Mohs micrographic surgery, using recurrence rate and cost of treatment for excision of basal cell carcinoma as indicators to validate our indications for Mohs surgery. DESIGN: Retrospective study of 557 head and neck basal cell carcinomas excised over 10 years. MAIN OUTCOME MEASURES: Recurrence rates; tumor comparisons by size, location, and subtype; a life table, and a patient satisfaction survey. RESULTS: Recurrence rate for the cross-sectional technique was 2.1% at 5 years. Recurrent tumors had an average diameter of 1.56 cm (vs 1.04 cm for nonrecurrent tumors). Recurrences were in the cheek (30%), nose (20%), temple (20%), forehead/brow (10%), conchal bowl (10%), and postauricular crease (10%). Recurrences were nodular cystic (40%), micronodular (20%), multifocal (10%), and infiltrating (30%). A total of 86.6% of patients surveyed rated the aesthetic outcome of their surgery favorably. The cost compared with the cost of Mohs excision varied depending on the Current Procedural Terminology coding technique. CONCLUSIONS: Cross-sectional frozen-section recurrence rates can compare favorably with Mohs micrographic surgery. The cross-sectional frozen-section technique generated a cost savings over Mohs surgery that may not hold true for all practice settings. Margin size did not adversely affect aesthetic results. Loupe magnification x2.5 is important in our technique. We also offer a useful definition for recurrence.

Racial differences in screening for prostate cancer in the elderly.

BACKGROUND: Black men are more likely than white men to be diagnosed as having advanced prostate cancer, and their prostate cancer mortality rates are more than twice as high. Low screening rates among black men may contribute to these disparities, but there are few data on racial differences in prostate cancer screening. OBJECTIVES: To present a case-control study of racial differences in the use of prostate-specific antigen (PSA) as a screening test among Medicare beneficiaries in New Jersey and to assess the degree to which race is associated with prostate cancer screening. METHODS: The study used a statewide database of claims data from Medicare Parts A and B, Medicaid, and the state's Pharmaceutical Assistance for the Aged and Disabled program. Prevalent cases of prostate cancer were excluded using the state's cancer registry. Of 139 672 men who underwent PSA screening, 34 984 were randomly selected along with an identical number of controls matched by month and year of birth. After men with International Classification of Diseases, Ninth Revision, Clinical Modification,or Current Procedural Terminology codes indicative of prostate cancer were excluded, 33 463 case patients and 33 782 control subjects remained. RESULTS: The use of PSA screening was strongly and inversely associated with black race (odds ratio [OR] = 0.50; P<.001), poverty (OR = 0.33; P<.001), and near poverty (OR = 0.69; P<.001). Multivariate logistic regression analysis after age, socioeconomic status, comorbidity, and use of health care services were controlled for revealed that black race remained a strong predictor of not undergoing PSA screening (OR = 0.65; 95% confidence interval, 0.60-0.70). CONCLUSIONS: Elderly blacks are substantially less likely to undergo PSA screening than elderly whites. Differences in socioeconomic status and comorbid conditions explain only a small part of the racial differences in screening rates.

Atherosclerotic disease in patients undergoing cataract extraction. A nationwide case-control study. The Cataract Patient Outcomes Research Team.

OBJECTIVE: To evaluate the association between cataract extraction and atherosclerosis and its complications. DESIGN: A nationwide case-control study. SETTING AND PARTICIPANTS: Using a 5% random sample of all Medicare beneficiaries, we analyzed Medicare claims data on 60803 persons 65 years of age and older who underwent cataract extraction in 1986 or 1987 and a control group of 63765 persons matched to the cases for age, race, sex, ZIP code, and reason for Medicare entitlement. MAIN OUTCOME MEASURE: Atherosclerosis and atherosclerosis-related disease and procedures were defined by International Classification of Diseases, Ninth Revision, Clinical Modification, codes or by Health Care Financing Administration Common Procedure Classification System (Current Procedural Terminology) codes. The strength of evidence for atherosclerotic disease was categorized on the basis of the types of bills in the Medicare claims file. RESULTS: Odds of atherosclerosis-related morbidity and procedures were higher for cases than for controls. The association decreased with patient age and was strongest in beneficiaries aged 65 to 69 years (odds ratio, 1.30; 95% confidence interval, 1.13-1.48). CONCLUSION: Our findings suggest that there is a weak association between a visually significant cataract requiring surgery and atherosclerosis in the younger elderly.

Payment under public and private insurance and access to cochlear implants.

BACKGROUND: Cochlear implants are expensive, yet often cost-effective. However, among hundreds of thousands of potential US candidates, only about 3000 received implants in 1999. To analyze whether insurance reimbursement levels may contribute to low access rates. DESIGN: Surveys were performed during 1999 and 2000 of physicians and audiologists at clinics providing cochlear implant services, selected hospitals where surgery is performed, and state Medicaid agencies. Secondary data were obtained on Medicare payment rates and hourly incomes of otolaryngologists and audiologists. PARTICIPANTS: One hundred thirty-one physicians (response rate 67.9%), 111 audiologists (74.0%), 60 hospitals (73.2%), and 44 Medicaid agencies (86.3%). OUTCOME MEASURES: Reimbursement rates for selected Current Procedural Terminology codes and for cochlear implant systems (devices); time required to perform services; additional time not reimbursed; and device purchase prices. RESULTS: Medicare and Medicaid payment rates often fail to cover costs of aural rehabilitation. Medicare sometimes and Medicaid often fails to cover surgeon costs. Sometimes private insurance does not cover hospitals' device costs. Under Medicare, in 1999 hospitals lost more than $10 000 per device for inpatient surgery and about $5000 per device for each outpatient surgery. Device reimbursement in 2002 for outpatient surgery under Medicare is about $3773 higher than in 1999. Medicaid device payment policies vary greatly and fail to cover costs in at least 18 states, accounting for 44% of national Medicaid enrollment. CONCLUSIONS: Efforts to expand access to cochlear implants may be impeded by financial incentives. Facilitating access for Medicare and Medicaid patients could require changes in payment policies.

Intraoperative cholangiography and risk of common bile duct injury during cholecystectomy.

CONTEXT: Intraoperative cholangiography (IOC) may decrease the risk of common bile duct (CBD) injury during cholecystectomy by helping to avoid misidentification of the CBD. OBJECTIVE: To characterize the relationship of IOC use and CBD injury while controlling for patient and surgeon characteristics. DESIGN, SETTING, AND PATIENTS: Retrospective nationwide cohort analysis of Medicare patients undergoing cholecystectomy from January 1, 1992, to December 31, 1999. Patients were identified using Current Procedural Terminology codes from the Medicare Part B depository. Common bile duct injury was defined by a second surgical procedure to repair the CBD injury within 1 year of cholecystectomy. Surgeon demographic features were obtained from matching the Medicare Part B data to the American Medical Association Physician Masterfile database. MAIN OUTCOME MEASURE: Frequency of CBD injury in patients who did and did not have IOC performed during cholecystectomy, controlling for patient-level (age, sex, race, and case complexity) and surgeon-level (surgeon's age, sex, race, year of surgical procedure, case order, percentage of IOC use in prior surgical procedures, years in medical practice, board certification, and specialization) factors. RESULTS: The database search identified 1 570 361 cholecystectomies and 7911 CBD injuries (0.5%). Common bile duct injury was found in 2380 (0.39%) of 613 706 patients undergoing cholecystectomy with IOC and in 5531 (0.58%) of 956 655 patients undergoing cholecystectomy without IOC (unadjusted relative risk, 1.49; 95% confidence interval, 1.42-1.57). After controlling for patient-level factors and surgeon-level factors, the risk of injury was increased when IOC was not used (adjusted relative risk, 1.71; 95% confidence interval, 1.38-2.28). While surgeons performing IOCs routinely had a lower rate of CBD injuries than those who did not, this difference disappeared when IOC was not used. CONCLUSIONS: In this study of Medicare patients undergoing cholecystectomy in the 1990s, the risk of CBD injury was significantly higher when IOC was not used. Although IOCs may not prevent all CBD injuries, this study suggests that the routine use of IOC may decrease the rate of CBD injury.
