ED coding and billing are challenging additions to the responsibilities of emergency physicians. Assurances that each is performed in the most efficient and accurate manner possible is an essential component of today's emergency medicine practice. Minimizing the risk for submitting fraudulent claims is critical, because it assures the efficient and timely billing of all ED services. For the practice to thrive, each is necessary.
Implementation of the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Canada (ICD-10-CA) and the Canadian Classification of Interventions (CCI) coding system presents challenges for using Canadian administrative data. Thus, a multi-step process was conducted to develop ICD-10-CA/CCI coding algorithms to define nine comorbidities and three procedures. These clinical variables have been used in ICD-9-CM data for risk adjustment in assessment of outcomes after aortic and mitral valve replacement surgery. Among patients included in the ICD-9-CM data during 1999 and 2001 and in the ICD-10-CA/CCI data during 2002 and 2003 in a Canadian Health Region, frequencies of the nine comorbidities and the three procedures remained generally similar across databases. The newly developed ICD-10-CA/CCI and previous ICD-9-CM coding algorithms are comparable in detecting these clinical variables. However, performance of ICD-10-CA/CCI coding algorithms in risk adjustment should be evaluated in a larger database.
Previous attempts to quantify the amount and type of orthodontic therapy provided by nonorthodontists in the United States have relied on survey data. Although there are advantages to surveys, such as control over survey recipients and inclusion of specific questions, they also have limitations, such as low response rates, response bias, and recall bias. This study used insurance claims data from a large dental benefits provider in Washington to assess the distribution of orthodontic services and fees among various dental providers. All orthodontic claims allowed by Washington Dental Service in 2001 were retrieved, along with treatment codes, fees, and demographic information for both patients and providers. A total of 102,984 orthodontic claims were included in the study. General dentists submitted 7.0% of these claims, orthodontists submitted 90.9%, and pedodontists submitted 1.9%. Orthodontists submitted higher average fees for space maintainers, first payments, and records. The percentage of orthodontic treatment preformed by general dentists and pedodontists in this claims-based study was substantially less than what has been previously reported in survey-based studies. Additionally, a smaller percentage of general dentists and pedodontists in this study performed comprehensive treatment, compared with previous studies. This study illustrates the value of insurance claims data to assess the provision of orthodontic care.
OBJECTIVES: To compare the association between the Case Mix Group (CMG) code and length of stay (LOS) with the association between the type of procedure and LOS in patients admitted for gynaecology surgery. METHODS: We examined the records of women admitted for surgery in CMG 579 (major uterine/adnexal procedure, no malignancy) or 577 (major surgery ovary/adnexa with malignancy) between April 1997 and March 1999. Factors thought to influence LOS included age, weight, American Society of Anesthesiologists (ASA) score, physician, day of the week on which surgery was performed, and procedure type. Procedures were divided into six categories, four for CMG 579 and two for CMG 577. Data were abstracted from the hospital information costing system (T2 system) and by retrospective chart review. Multivariable analysis was performed using linear regression with backwards elimination. RESULTS: There were 606 patients in CMG 579 and 101 patients in CMG 577, and the corresponding median LOS was four days (range 1-19) for CMG 579 and nine days (range 3-30) for CMG 577. Combined analysis of both CMGs 577 and 579 revealed the following factors as highly significant determinants of LOS: procedure, age, physician, and ASA score. Although confounded by procedure type, the CMG did not significantly account for differences in LOS in the model if procedure was considered. Pairwise comparisons of procedure categories were all found to be statistically significant, even when controlled for other important variables. CONCLUSION: The type of procedure better accounts for differences in LOS by describing six statistically distinct procedure groups rather than the traditional two CMGs. It is reasonable therefore to consider changing the current CMG codes for gynaecology to a classification based on the type of procedure.
OBJECTIVES: Ectopic pregnancy is a common condition with significant health consequences; complications are a major cause of maternal mortality in the United States. Accurate ascertainment of the number of ectopic pregnancies occurring in the United States has been dramatically affected by changing medical practices, causing estimates based on hospital data to be falsely low. This study was performed to identify nationally representative data on ectopic pregnancies and determine overlap of these data, to calculate the annual weighted number of ectopic pregnancies and confidence intervals for these estimates, and to determine barriers to estimation of ectopic pregnancy incidence. METHODS: To assess whether a national estimate of the incidence of ectopic pregnancy could be calculated, we analyzed 1992-99 data from the six nationally representative data sets that include information on ectopic pregnancy. We examined relevant data in each data set and assessed whether any combination of data sets could be used to estimate ectopic pregnancy incidence. We calculated weighted estimates and 95% confidence intervals for hospitalizations, outpatient surgeries, outpatient medical procedures, and physician visits for and self-reports of ectopic pregnancy. RESULTS: Small sample sizes severely limited calculation of estimates of ectopic pregnancy. Data needed for assessing multiple counting was not available consistently. The likelihood of multiple counting of cases was substantial when data set counts were combined. CONCLUSIONS: A reliable incidence rate for ectopic pregnancy in the United States could not be estimated from existing nationally representative data sources. Major advances in diagnosis and treatment of ectopic pregnancy have affected surveillance in two ways: inpatient hospital treatment of ectopic pregnancy has decreased, and multiple health care visits for a single ectopic pregnancy have increased. Alternate means of surveillance are needed to improve understanding of risk factors and trends for ectopic pregnancy, and we recommend examination of the databases of public and private insurance systems and managed care systems. Similar alternate means of surveillance may be needed for other health conditions with comparable changes in management of care.
BACKGROUND: A problem area in the reimbursement of physicians is the office visit at which both procedures and evaluation/management services are performed. Insurers are concerned that frequent reporting of diagnoses unrelated to procedures may represent an abuse of the claims process. OBJECTIVE: To determine the frequency of secondary diagnoses that are present at visits at which procedures are performed and to compare the frequency with that reported in Medicare claims. METHOD: The 1998 and 1999 National Ambulatory Medical Care Survey (NAMCS) data were used to provide data unrelated to claims for payment. The results were compared with Medicare claims data from the 1998 to 1999 Medicare Current Beneficiary Survey. NAMCS visits were limited to patients who were 65 year old or greater to limit the analysis to the Medicare population. RESULTS: In the NAMCS dataset, 52% of the visits for actinic keratoses at which a procedure was performed were associated with multiple diagnoses. Similarly, in the Medicare Current Beneficiary Survey dataset, 52% of these visits had multiple diagnoses listed. CONCLUSION: The frequency of visits with multiple diagnoses is the same in both administrative claims and epidemiologic survey databases. There is no evidence for widespread abusive coding by physicians. It is incumbent on payers to respect the integrity of the coding system in order to assure fair reimbursement for physician services.
OBJECTIVE: To determine whether access to reimbursement increases anesthesiologists' use of intraoperative transesophageal echocardiography (TEE). DESIGN: Survey. SETTING: United States. PARTICIPANTS: Members of the Society of Cardiovascular Anesthesiologists, local Medicare carriers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: In year 2000, local Medicare carrier policies specifically allowed some form of reimbursement to the attending anesthesiologist for intraoperative TEE in 15 states, but barred all forms of reimbursement in 16 states and Puerto Rico. Data regarding utilization and billing were available for 702 members of the Society of Cardiovascular Anesthesiologists from these jurisdictions who used TEE in their anesthetic practice. Billing patterns were found to vary significantly according to the local Medicare policy in effect (p = 0.004). Use of intraoperative TEE was found to be unrelated, however, to the reimbursement available from Medicare (p = 0.2 to 0.7). CONCLUSION: The use of intraoperative TEE by anesthesiologists does not seem to be related to the availability of reimbursement from Medicare.

OBJECTIVE: In a prospective study we analysed the quality of ICD-coding in clinical everyday life of a department for internal medicine. METHODS: A skilled intern--the so-called DRG assistant--was temporarily released from clinical work. Over nine weeks he had to control all diagnoses contemporaneously that were ICD-coded by his colleagues on admission and discharge of their patients. The DRG-assistant had to ask for missing or correct implausible diagnoses, or inappropriate ICD-coding and with it also train his colleagues in appropriate coding. The effects of the DRG-assistant's correction of coding, on DRG-consistent grouping and on the potential financial loss or benefit generated by his work were recorded. After stoppage of this control in a subsequent phase of the study the effect of the absence of the DRG-assistant, the absence of reminders and coding control and the changes of the clinic's revenue were determined. RESULTS: Corrections of ICD-coding by the DRG-assistant alone caused a remarkable increase in case-mix-index (CMI). CMI's mean value increased from 1.76 to 1.84 and the clinic's revenue increased by 180 Euro per patient (a total of about 80,000 Euro in nine weeks). After the end of the control, the case-mix-index dropped within three weeks down to 1.14, corresponding with a potential loss of 1200 Euro per patient (assuming that patients' morbidity was the same over the time of the study). Coding corrections could not improve CMI in this situation. CONCLUSION: Contemporaneous control of ICD-coding by physicians seems to be essential in DRG based accounting.

Public health and financial aspects of cholecystectomy related bile duct injury (BDI) are highlighted in a National Cholecystectomy Survey carried out through 'datamining' the Federal State Medical Records Summaries and Financial Summaries of all Belgian hospitals in 1997. All cancer diagnoses, children < or = 10 years, cholecystectomies performed as an abdominal co-procedure or patients having undergone other non-related surgery were excluded from the study. 10.595 laparoscopic (LC) and 1.033 open cholecystectomies (OC) as well as 137 secondary BDI treatments (LC/OC) were included in the survey (total 11.765). Both LC and OC groups turned out to be significantly different as to distribution of patient's age and APR-DRG severity classes. Composite criteria in terms of ICD-9-CM and billing codes were elaborated to classify: 1) primary, intra-operatively detected and treated BDI (N = 30), 2) primary delayed BDI treatments (N = 38), 3) secondary BDI treatments (N = 137), 4) non-BDI abdomino-surgical complications (N = 119), 4) uneventful laparoscopic (N = 7.476) and 5) uneventful open cholecystectomy (N = 681). Complication rates, community costs of LC and OC groups, incidence of preoperative ERCP and/or intra-operative cholangiography as well as interventions for complications were studied. Incidence of cholecystectomy related BDI was 0.37% in LC, 2.81% in OC and 0.58% overall. Average costs amounted to [symbol: see text] 1.721 for uneventful LC, [symbol: see text] 2.924 for uneventful OC, [symbol: see text] 7.250 for primary, intra-operatively detected and immediately treated BDI [symbol: see text] 9.258 for primary delayed BDI treatments, [symbol: see text] 6.076 for secondary BDI treatments and [symbol: see text] 10.363 for non-BDI abdomino-surgical complications. In conclusion BDI with cholecystectomy reveals to be a serious complication increasing the overall average cost factor ninefold if not detected intra-operatively, in which case the raise is only fourfold. As a consequence BDI should be avoided by all means. In this respect 4 crucial surgical guidelines are emphasised.
Oral rotavirus vaccine was voluntarily withdrawn from the market after studies observed an increased risk of intussusception within 2 weeks after immunization. Concern has been raised that other orally administered vaccines, such as oral poliovirus vaccine (OPV), may also be associated with intussusception. In this 1990-1998 case-control study, the authors examined the association between OPV and intussusception in the Washington State Medicaid population, evaluating receipt of OPV during the month prior to intussusception among 119 cases and 589 controls matched by date of birth. Analysis was conducted via matched conditional logistic regression, controlling for sex. Between 1990 and 1998, 119 children younger than age 2 years had a therapeutic enema, surgical reduction, or hospitalization for intussusception and had been enrolled in Medicaid for at least 1 month prior to their intussusception date. There was no significantly elevated risk of intussusception associated with receipt of OPV; 9.2% (11/119) of cases and 8.5% (50/589) of controls were given OPV 0-28 days prior to the case's intussusception date (odds ratio=1.1, 95% confidence interval: 0.5, 2.2). However, to address the hypothesis that risk of intussusception is related to receipt of a particular dose of OPV, a larger study would be required.
PURPOSE: Public hospitals and academic medical centers may admit more poorly insured transfer patients than do other institutions. The authors investigated the relationship of patient insurance status, hospital ownership, and hospital teaching status with interhospital transfers in California. METHOD: In 2003, data were derived from the hospital discharge abstract database for the year 2000 from the California Office of Statewide Health Planning and Development. Hospitals were categorized by ownership and teaching status; patients were categorized as being "good" or "poor" payers depending on the level of expected insurance reimbursement. Descriptive and multivariate analyses were used to assess the number of poor payer transfers admitted by each hospital group. RESULTS: In 2000, there were 58,509 transfer and 2,320,479 direct admissions. All hospital groups admitted a higher percentage of good payer than poor payer transfer patients (85% vs. 15% respectively for all groups combined). Adjusted for total number of admissions and teaching status, the number of poor payer transfer patients admitted to county-owned and University of California hospitals was significantly higher than the statewide average (both p values < .001), while the number admitted to independent teaching hospitals was significantly lower than the statewide average (p < .001). The number of poor payer transfer patients admitted to independent teaching hospitals more closely resembled that of for-profit hospitals than that of University of California teaching hospitals. CONCLUSIONS: In 2000, the likelihood of a hospital admitting a transfer patient appears to have been affected by both the patient's insurance status and the hospital's ownership. In general, good payer patients were more likely to be transferred than were poor payer patients, with poor payer transfer patients more likely to be admitted to publicly owned hospitals.
