Comparison of nurse practitioner and family physician relative work values.

PURPOSE: With the enactment of the Balanced Budget Act of 1997, American nurse practitioners were granted direct Medicare reimbursement for Part B services. Payment structures in fee-for-service and managed care systems are physician-based, leading to difficulties in constructing payments for other health care professionals. The purpose of this pilot study was to examine the feasibility of using nurse practitioner data for specifying relative work values in the Medicare Fee Schedule for three office-visit codes. DESIGN: An exploratory survey was designed to establish relative work values using magnitude-estimation scaling. Nurse practitioners (N = 43) responded to a structured questionnaire in a national mail survey. Physician data (N = 46) were obtained from a computerized database from the American Academy of Family Physicians. METHODS: The methods used in this study were the same as the process used by the American Medical Association and the Health Care Financing Administration to establish relative work values in the Medicare Fee Schedule. Respondents established relative work values for three Current Procedural Terminology (CPT) codes for office visits (99203, 99213, 99215) commonly billed in primary care practice. Each CPT code descriptor and associated vignette were compared with reference services germane to the practice of nurse practitioners and family physicians, using magnitude-estimation scaling. To establish relative work values for each code, respondents were asked to consider the time to provide the service and intensity of the work involved for each CPT code. FINDINGS: No significant differences between nurse practitioners and family physicians were found in the three CPT codes for relative work values and intensity. Nurse practitioners estimated significantly (p < .01) higher intraservice (face to face) time with patients than did family physicians, and family physicians estimated significantly (p < .05) higher pre-service time for two codes and significantly (p < .05) higher postservice times for three codes. CONCLUSIONS: Nurse practitioner relative work values did not differ significantly from family physician relative work values. Although the sample sizes were small, the significance of the findings support the need for further research with large data sets and additional CPT codes. Such studies could then be used as a basis for decisions about Medicare payment and public policy.

Medicare charges and the operational-year coding concept.

The introduction by the Health Care Financing Administration, in 1993, of separate conversion factors for "medical" and "surgical" services to be used in calculating Medicare charges would ordinarily necessitate the use of year-specific software source code. By designing the system to utilize macro-substitution of the year in the names of Current Procedural Terminology for Physicians Code databases, database fields, and system variables, it is possible to calculate Medicare charges without annually rewriting source code. Once such a system is in place, simply by changing the operational year, the correct data and means of computation are automatically available.

Trends in the utilization of MR angiography and body MR imaging in the US Medicare population: 1993-1998.

PURPOSE: To determine the trends in utilization of non-neurologic (ie, body) magnetic resonance (MR) imaging and of MR angiographic examinations performed from 1993 to 1998, the trends in non-radiologist participation in MR imaging, and the relative reimbursements for these examinations compared with those for all other noninvasive imaging studies performed in 1998. MATERIALS AND METHODS: By using the 1993, 1996, and 1998 nationwide Medicare Part B databases, utilization rates per 100,000 Medicare beneficiaries and physician reimbursements were determined for seven MR angiography and 14 body MR imaging CPT-4 (Current Procedural Terminology, version 4) codes. Medicare specialty codes were used to categorize physicians as radiologists or non-radiologists. RESULTS: The utilization rate per 100,000 Medicare beneficiaries for all 21 MR angiography and body MR imaging codes increased from 649 in 1993 to 1,253 in 1996 and to 1,876 in 1998--a 189% increase. These rates represented 0.55% of the total noninvasive imaging volume in 1998 and 2.8% of physician reimbursements. Musculoskeletal MR imaging utilization increased 142% from 1993 to 1998 compared with a 58% increase in the utilization of other body MR imaging studies. Non-radiologist participation in musculoskeletal MR imaging increased from 2.9% in 1993 to 3.6% in 1996 and to 5.6% in 1998. CONCLUSION: MR angiography and body MR imaging utilization rates increased substantially from 1993 to 1998. However, these studies still account for a minor fraction of all noninvasive imaging examinations performed and fees reimbursed. MR angiography and musculoskeletal MR imaging utilization has increased rapidly. Non-radiologist participation in musculoskeletal MR imaging is increasing.

Spinal injection procedures: volume, provider distribution, and reimbursement in the U.S. medicare population from 1993 to 1999.

PURPOSE: To evaluate spinal injection procedures for trends in volume, reimbursement, and physician specialty participation. MATERIALS AND METHODS: By using the 1993, 1996, 1998, and 1999 Medicare Part B claims database, we studied Current Procedural Terminology revision 4 codes used for percutaneous spinal injection procedures, including cervical and lumbar discography, disk aspiration and/or injection, facet and/or perifacet joint injection, and epidural steroid injection. For each of these procedures, volume, reimbursement, and physician specialty participation (categorized as radiology, anesthesiology, surgery, physiatry, and other specialties) for each year were recorded. RESULTS: Despite an overall increase in spinal injection procedure volume and reimbursement from 1993 to 1999, nonradiologists performed most of these procedures. Epidural steroid and facet joint injections had the highest volume and reimbursement during this time period and were performed almost exclusively by nonradiologists (predominantly anesthesiologists). Radiologists performed more discography procedures than did other specialists in 1993, but participation decreased each year, while anesthesiologist participation increased; as of 1999, anesthesiologists performed more discography procedures than did radiologists. Although radiologists performed more disk aspiration procedures than did other specialists, procedure volume remained low during the period studied. CONCLUSION: Spinal injection volume and reimbursement have increased substantially in the Medicare population from 1993 to 1999. During this interval, radiologist participation has decreased. Nonradiologists perform most spinal injection procedures.

Performance of neuroradiologic examinations by nonradiologists.

PURPOSE: To determine the level of participation by nonradiologists in performing neuroradiologic examinations. MATERIALS AND METHODS: Medicare part B claims data from fiscal year 1992 were analyzed for CPT (current procedural terminology) codes related to computed tomography (CT) and magnetic resonance (MR) imaging of the brain, head and neck, and spine, as well as myelography, angiography, and diskography. Data were tabulated by place of service (hospital-based vs freestanding imaging centers) and by medical specialty. RESULTS: Among 363,224 Medicare claims for CT and MR imaging of the brain, head and neck, and spine, 91% of the examinations were performed in hospitals and 9% in offices or freestanding centers; 98% of studies were interpreted by a radiologist. The largest share of radiology billing by nonradiologists was from office-based or freestanding imaging centers (9%), versus 2% at hospital-based facilities. CONCLUSION: Radiologists perform the vast majority of neuroradiologic examinations. Most neuroradiologic examinations performed by nonradiologists are from neurologists at freestanding/office-based imaging centers.

Who performs neuroimaging? Results from the 1993 National Medicare Database.

PURPOSE: To determine the level of participation of nonradiologists in computed tomography (CT) and magnetic resonance (MR) imaging of the brain, head and neck, and spine at hospitals and at private offices and imaging centers in the United States. MATERIALS AND METHODS: The 1993 Part B Medicare Annual Database was used to determine the number of procedures performed by radiologists and nonradiologists at hospitals and at private offices or imaging centers. The fourth edition of the Physicians' Current Procedural Terminology was used to classify procedures. RESULTS: Of the 3,883,391 neurologic CT and MR imaging studies billed to Medicare in 1993, 3,148,088 (81%) were obtained in a hospital setting; only 58,005 (2%) of these studies were interpreted by nonradiologists. Of the 735,303 imaging studies (19%) obtained at a private office or imaging center, only 63,115 (9%) studies were interpreted by nonradiologists. Overall, nonradiologists performed only 121,120 (3%) of the neuroimaging examinations billed to Medicare nationwide in 1993. CONCLUSION: The level of participation of nonradiologists in the interpretation of results from neurologic CT and MR imaging billed to Medicare is minimal.

Design of a privileging program for diagnostic imaging: costs and implications for a large insurer in Massachusetts.

PURPOSE: To evaluate the results of a privileging program aimed to ensure that health care providers and facilities adhere to standards of care. MATERIALS AND METHODS: Technical and professional privileging applications were mailed to more than 1,800 diagnostic imaging facilities and more than 6,000 professional providers of services to members of a health care plan. Site inspections were used to determine whether facilities met standards of care. Specialty providers were assigned a range of current procedural terminology codes for which they had privileges to bill the payer. RESULTS: Of 1,004 imaging sites inspected, 197 (20%) failed with the ability to remedy the violation, 106 (10%) failed with fundamental and serious deficiencies, and 701 (70%) passed. Site inspection pass rates varied substantially by specialty. Chiropractors and podiatrists were more likely to fail than medical and surgical specialists. A strong correlation was found between refusal to participate in the inspection and failure rate. Results suggest that reduction of the number of professional claims billed led to a 2% decline in total imaging expenditures, or a more than 10:1 return on the cost of implementing technical and professional privileging programs. CONCLUSION: Health care plans can positively influence costs and quality by developing, monitoring, and enforcing their own quality standards for diagnostic imaging.

Psychiatric outpatient practice: patterns and policies.

OBJECTIVE: The purpose of this paper is to explore possible consequences of recent changes in the Medicare payment schedule for office-based psychiatric services. METHOD: Psychiatric office visits from the 1985 National Ambulatory Medical Care Survey were categorized in a manner that approximates commonly used codes of the Physicians' Current Procedural Terminology. An analysis was conducted of the frequency and clinical characteristics of various types of services, focusing particularly on visits of under 20 minutes in length that included a medication prescription (medication visits) and other visits of 35 minutes or less in duration (brief visits). RESULTS: Medication visits and brief visits together accounted for more than one-quarter (27.3%) of all U.S. psychiatric office visits. The relative risk of receiving these short visits was greater for patients who paid with public resources, were over 65 years of age, were nonwhite in race (brief visits only), received a prescription for an antipsychotic medication, or were diagnosed as having a psychotic disorder. CONCLUSIONS: Short office visits are provided to a particularly vulnerable patient population. The reduction in Medicare copayments for medication management services should increase the patient demand for these short visits. However, where the new Medicare schedule has lowered physician fees for these services, the financial incentive to provide short visits will decrease and patient access may become limited.

Measuring the determinants of work values for psychiatrists' services in the resource-based relative value scale study.

OBJECTIVE: As part of the Harvard resource-based relative value scale study, the authors investigated how well the codes in the Physician's Current Procedural Terminology, 4th edition, or CPT-4, match psychiatric services to the work involved in evaluating and managing patients and how patient care characteristics affect different levels of psychiatric work. METHOD: A random sample of over 200 psychiatrists and subspecialists was asked to use 68 typical clinical examples or vignettes to evaluate services described by CPT codes. Data were analyzed by multivariate statistical methods. RESULTS: The survey showed that the existing coding system does not adequately describe the work that psychiatrists do. Within a single code (e.g., 90844, individual medical psychotherapy), there was wide (more than twofold) variation in the estimates, from multiple measurements based on different vignettes, of the amount of work represented. Estimates of work values varied significantly according to treatment setting and patient characteristics: psychiatric services in the hospital showed an average work value 25% greater than that for office services; treating new patients involved 18% more effort than treating established patients; and treating patients described as at risk of harming self or others increased the psychiatrists' work effort by 36%. CONCLUSIONS: Revisions in coding evaluation and management services in the new Medicare fee schedule for psychiatric services should be further refined and then implemented. These revisions would bring the coding system into line with psychiatric practice, making it a better way of accounting for the relative work involved in treating patients of varying difficulty.

Role of a medical staff coding committee in documentation, coding, and billing compliance.

Physician documentation, Current Procedural Terminology (CPT) coding, and compliance with federal billing regulations are essential given the government's significant efforts to address fraud and abuse and the grave financial and legal consequences of noncompliance. Because Medicare guidelines do not focus substantially on psychiatric care, compliance is especially challenging for psychiatrists and psychiatric centers. Four years ago, the University of Texas-Harris County Psychiatric Center formed a medical staff coding committee to assist the center and its psychiatrists in dealing with compliance issues. The committee has evolved into a highly effective and important component of the institution's overall compliance program. The authors discuss the origins, development, and accomplishments of the medical staff coding committee.

Considering school health program screening services as a cost offset: a comparison of existing reimbursements in one state.

This paper reports results of an analysis of the approximate costs of Colorado school health program screening activities during the 1993/94 school year had they been conducted elsewhere in the public or private sectors. School nurses and health aides performed 1,161,779 screening procedures during the year, an average of 1.93 per child enrolled in school districts throughout the state. Charges for Current Procedures Terminology (CPT) codes, which correspond to school health program screening activities, were used to approximate market value. Conservative assumptions were made regarding provider skill and time requirements as well as student service utilization profiles. The general dimension of the contribution of school health screening activities was found to be impressive.

Outpatient foot care: correlation to amputation level.

A retrospective analysis of Department of Veterans Affairs automated inpatient and outpatient records was performed for 3945 patients who underwent lower extremity amputation surgery due to peripheral vascular disease during fiscal year 1991. Demographic and clinical data were collected from reviewing patient database information for all Department of Veterans Affairs Hospitals nationwide. Patients were identified from the Physicians' Current Procedural Terminology codes for lower extremity amputations, and then divided into three groups (above the knee, below the knee, and foot and ankle) based on the most proximal level of amputation performed. Results indicate that increased use of designated foot care clinics was significantly associated with more distal level amputation surgery. Patients with above-the-knee amputations averaged 1.0 foot care clinic visit in the 2 years prior to amputation, whereas below-the-knee and foot and ankle amputees averaged 2.8 and 5.3 foot care clinic visits, respectively (F[df = 2,3939] = 94.20, P < .05). The same finding was noted when only users of foot care clinics were examined. Patients with a codiagnosis of diabetes were more likely to undergo distal amputation than those with other diagnoses (P < .05). The results of this study suggest the potential effectiveness of designated foot care clinics in preserving limb length in individuals with peripheral vascular disease and diabetes.

Medical informatics standards applicable to emergency department information systems: making sense of the jumble.

The adoption of medical informatics standards by emergency department information systems (EDISs) is not universal, despite obvious benefits. Clinicians and administrators looking to obtain an EDIS need to know exactly what the various standards can do for them and how the systems they depend on can be integrated and extended. In addition to the standard methods for systems to communicate (chiefly Health Level 7 [HL7]) and those required for submission of claims (Current Procedural Terminology [CPT]-4, International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM], and X12N), there are several other available standards that are clinically useful and can greatly improve the ability to access and exchange patient information. Major advances in the Unified Medical Language System of the National Library of Medicine have made the patient medical record information standards (Systematized Nomenclature of Medicine [SNOMED], Logical Observation Identifiers, Names, and Codes [LOINC], RxNorm) easily accessible. Detailed knowledge of the arcana associated with the technical aspects of the standards is not needed (or desired) by clinicians to use standards-based systems. However, some knowledge about the commonly used standards is helpful in choosing an EDIS, interfacing the EDIS with the other hospital information systems, extending or upgrading systems, and adopting decision support technologies.

The Health Care Financing Administration's new examination documentation criteria: minimum auditing standards for the neurologic examination to be used by Medicare and other payors. Report from the American Academy of Neurology Medical Economics and Management Subcommittee.

Medicare recently announced the adoption of minimum documentation criteria for the neurologic examination. These criteria are added to existing standards for the history and medical decision-making. These criteria will be used in compliance audits by Medicare and other payors. Given the current federal initiative to eliminate fraud in the Medicare program, all neurologists need to comply with these standards. These criteria are for documentation only. Neurologic standards of care require a more complex and diverse examination pertinent to the problem(s) under consideration. Further guidance as to the content of a neurologic evaluation is outlined in the article "Practice guidelines: Neurologic evaluation" (Neurology 1990; 40: 871). The level of history and examination required for specific services is defined in the American Medical Association current procedural terminology book. Documentation standards for examination of children are not yet defined.

Selective application of cardiopulmonary resuscitation improves survival rates.

This study is a retrospective review of all patients who died without cardiopulmonary resuscitation (CPR) or who sustained a sudden cardiopulmonary arrest in the hospital and received CPR during a 2-yr period at a large medical center. Based on a review of Current Procedural Terminology codes, patients were classified into one of the ten disease categories: multiple medical problems, acute disease, procedure-related, congenital disease, neoplasm, metastatic neoplasm, trauma, burn, acquired immunodeficiency syndrome, and dementia. A total of 1206 patient deaths without a CPR effort were identified. CPR was administered to another 550 patients who had a sudden cardiopulmonary arrest, of which 71% survived the resuscitative attempt initially, but only 25% survived CPR until discharge from the hospital. CPR was applied less frequently than the mean in the metastatic neoplasm (P < 0.0001), trauma (P = 0.013), and dementia (P = 0.0003) groups and more frequently in the acute disease (P < 0.0001) and procedure-related (P < 0.0001) groups. Survival to discharge from the hospital was more frequent than the mean in the congenital disease group (P = 0.0004) and less frequent in the neoplasm group (P = 0.0425). The other groups had survival rates comparable to the mean. Patients 70 yr of age and older were less likely to receive CPR than those younger than 70 (P < 0.0001). However, if they did receive CPR, they were just as likely to survive to discharge from the hospital as the younger patients (P = 0.3404).(ABSTRACT TRUNCATED AT 250 WORDS)

Predicting anesthesia times for diagnostic and interventional radiological procedures.

We studied anesthesia times for diagnostic and interventional radiology using anesthesia billing data and paper radiology logbooks. For computerized tomography and magnetic resonance imaging procedures, we tried to predict future anesthesia times by using historical anesthesia times classified by Current Procedural Terminology (CPT) codes. By this method, anesthesia times were estimated even less accurately than operating room cases. Computerized tomography and magnetic resonance imaging had many different CPT codes, most rare, and CPT codes reflected organs imaged, not scanning times. However, when, anesthesia times were estimated by expert judgment, face validity and accuracy were good. Lower and upper prediction bounds were also estimated from the expert estimates. For interventional radiology, predicting anesthesia times was challenging because few CPT codes accounted for most cases. Because interventional radiologists scheduled their elective cases into allocated time, the necessary goal was not to estimate the time to complete each case but rather the time to complete each day's entire series of elective cases including turnover times. We determined the time of day (e.g., 4 pm) up to when interventional radiology could schedule so that on 80% of days the anesthesia team finishes no later than a specified time (e.g., 6 pm). Both diagnostic and interventional radiology results were similarly less accurate when Version 9 of the International Classifications of Diseases' procedure codes was used instead of CPT.

Medicaid and Medicare reimbursement for flow cytometry.

Medicaid, a program administered by individual states but involving federal funding, is the source of medical coverage for many low-income patients. This method of reimbursement is crucial for many flow cytometry laboratories, but is not well understood by many laboratory professionals. Conversely, flow cytometry often is not well understood by administrators in Medicaid offices. The potential exists for great variation in Medicaid reimbursement for flow cytometry services from state to state. As a first step toward elucidating the extent of this variation and bringing more information about Medicaid to laboratory professionals, state Medicaid offices were asked to provide the fee-for-service reimbursement for flow cytometry services. These services included Current Procedural Terminology (CPT) codes 85045 (reticulocyte counts), 86359 (total T-cell count), 86360 (absolute CD4 and CD8 counts, with ratio), 86361 (absolute CD4 count), 86812 (HLA typing, single antigen [B27]), 88180 (immunophenotyping, per surface marker), and 88182 (DNA, cell cycle analysis). Data were collected on technical and professional components and on global reimbursement. Wide variation exists in reimbursement amounts for these tests. Variation for CPT code 88180 was markedly pronounced.

Medication therapy management services: a critical review.

OBJECTIVE: To identify and examine medication therapy management (MTM) practice and compensation models currently being used by public and private sector programs, develop a model for payers to consider in compensating pharmacists for the provision of MTM services, and review how a relative value-based payment system based upon Current Procedural Terminology (CPT) codes might apply to MTM services. DATA SOURCES: Peer-reviewed literature; study of existing MTM practice and compensation models; interviews with pharmacists, pharmacy benefit providers, health plans, and policy makers; structured discussions with industry experts. SUMMARY: Implementation of MTM represents an opportunity for pharmacists to provide public and private payers with examples of service packages and business models that improve patient therapeutic outcomes. MTM services can lead to overall cost reductions and improved health outcomes. Recommendations for pharmacists, health plans, and Medicare Part D prescription drug plan sponsors are provided. Pharmacists should standardize and package MTM services at varying levels of intensity; determine work values for MTM CPT codes, use standards for billing and service delivery, build supply capacity to meet demand for MTM services, and cultivate patient and provider support for pharmacist-provided MTM services. Plans and sponsors should develop mechanisms for measuring MTM impact on overall health care costs and develop payment systems to cover costs as well as sustain and provide for growth in the number of providers. CONCLUSION: The essential components of MTM business and payment models, as outlined in this article, can be effectively mapped to relative value-based CPT codes for pharmacist-provided MTM services. Pharmacy providers, after considering various factors and conditions in their own environment, can develop an optimal MTM service package and business model based on this information.
