MMPI-based personality types among juvenile sexual offenders.

The MMPIs of 262 adolescent males who committed sexual offenses were categorized by means of cluster analysis into four distinct groups. Each of these groups was found to contain different two-point code types. Referral offense, historical and clinical data were compared for each of the four cluster groups and for each of the two-point code types; the latter provided more reliable discrimination among groups. The four modal personality types suggested by the cluster analysis indicate, contrary to previous research, that juvenile sexual offenders are a heterogeneous group who represent a wide variety of personality traits and levels of adaptation.

Accuracy of diagnostic coding for Medicare patients under the prospective-payment system.

Reimbursement of hospitals by Medicare under the prospective-payment system is based on patients' diagnoses as coded at discharge. During the period October 1984 through March 1985, we studied the accuracy of the coding for diagnosis-related groups (DRGs) in hospitals receiving Medicare reimbursement. We used a two-stage cluster method to sample 7050 medical records from 239 hospitals that were stratified according to size. Using blinded techniques with reliability checks, medical-record specialists reabstracted the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes to assign correct DRGs to discharged patients. The correct DRGs were then compared with those originally assigned by the physician and the hospital administration. The study revealed an error rate of 20.8 percent in DRG coding. Errors were distributed equally between physicians and hospitals. Small hospitals had significantly higher error rates. Previous studies had found that errors occurred randomly, so that half the errors benefited the hospital financially and half penalized the hospital. The present study found that a statistically significant 61.7 percent of coding errors favored the hospital. These errors caused the average hospital's case-mix index--a measure of the complexity of illness of the hospital's patients--to increase by 1.9 percent. As a result, hospitals received higher net reimbursement from Medicare than was supportable by the medical records. We conclude that "creep" does occur in the coding of DRGs, resulting in overpayment to hospitals for patients covered by Medicare.

Extended-spectrum beta-lactamases in clinical isolates of enterobacteria in Mexico.

Resistance to extended-spectrum cephalosporins within members of the family Enterobacteriaceae occurs virtually world-wide. Nevertheless, nothing was known about this problem among isolates from Mexico. To address this issue, we studied oximino-cephalosporin resistant isolates of Klebsiella pneumoniae (13), Escherichia coli (7), and Enterobacter cloacae (23) recovered from patients in Mexico City hospitals during 1990 to 1992. In the presence of clavulanic acid, these strains increased susceptibility to cefotaxime and ceftazidime (MIC90 64 and >256 microg/ml, respectively). The ability of these isolates to transfer resistance to both antibiotics by conjugation was most successfully demonstrated by K. pneumoniae. In all the clinical isolates tested, the largest plasmid coded for the extended-spectrum beta-lactamases (ESBL). Characteristics of pI, by isoelectric focusing (IEF)/bioassay and DNA hybridization with specific probes of TEM and SHV, indicated that in most of the clinical isolates and all transconjugates, the most frequent beta-lactamase coded were SHV-derived (20 strains as 41% of isolates) and a plasmid-encoded beta-lactamase (12 strains as 25% of isolates) (with a pI of >8.2), which is not related to TEM/SHV. Apparently, isolates from Mexico show characteristics similar to isolates from other geographic areas. The type of beta-lactamases coded in these resistant isolates is documented for the first time in Mexico.

Reinventing radiology reimbursement.

Lee Memorial Health System (LMHS), located in southwest Florida, consists of 5 hospitals, a home health agency, a skilled nursing facility, multiple outpatient centers, walk-in medical centers, and primary care physician offices. LMHS annually performs more than 300,000 imaging procedures with gross imaging revenues exceeding dollar 350 million. In fall 2002, LMHS received the results of an independent audit of its IR coding. The overall IR coding error rate was determined to be 84.5%. The projected net financial impact of these errors was an annual reimbursement loss of dollar 182,000. To address the issues of coding errors and reimbursement loss, LMHS implemented its clinical reimbursementspecialist (CRS) system in October 2003, as an extension of financial services' reimbursement division. LMHS began with CRSs in 3 service lines: emergency department, cardiac catheterization, and radiology. These 3 CRSs coordinate all facets of their respective areas' chargemaster, patient charges, coding, and reimbursement functions while serving as a resident coding expert within their clinical areas. The radiology reimbursement specialist (RRS) combines an experienced radiologic technologist, interventional technologist, medical records coder, financial auditor, reimbursement specialist, and biller into a single position. The RRS's radiology experience and technologist knowledge are key assets to resolving coding conflicts and handling complex interventional coding. In addition, performing a daily charge audit and an active code review are essential if an organization is to eliminate coding errors. One of the inherent effects of eliminating coding errors is the capturing of additional RVUs and units of service. During its first year, based on account level detail, the RRS system increased radiology productivity through the additional capture of just more than 3,000 RVUs and 1,000 additional units of service. In addition, the physicians appreciate having someone who "keeps up with all the coding changes" and looks out for the charges. By assisting a few physicians' staff with coding questions, providing coding updates, and allowing them to sit in on educational sessions, at least 2 physicians have transferred some their volume to LMHS from a competitor. The provision of a "clean account," without coding errors, allows the biller to avoid the rework and billing delays caused by coding issues. During the first quarter of the RRS system, the billers referred an average of 9 accounts per day for coding resolution. During the fourth quarter of the system, these referrals were reduced to less than one per day. Prior to the RRS system, resolving these issues took an average of 4 business days. Now the conflicts are resolved within 24 hours.

Optimizing coding and reimbursement to improve management of Alzheimer's disease and related dementias.

The objectives of this study were to review the diagnostic, International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM), diagnosis related groups (DRGs), and common procedural terminology (CPT) coding and reimbursement issues (including Medicare Part B reimbursement for physicians) encountered in caring for patients with Alzheimer's disease and related dementias (ADRD); to review the implications of these policies for the long-term clinical management of the patient with ADRD; and to provide recommendations for promoting appropriate recognition and reimbursement for clinical services provided to ADRD patients. Relevant English-language articles identified from MEDLINE about ADRD prevalence estimates; disease morbidity and mortality; diagnostic coding practices for ADRD; and Medicare, Medicaid, and managed care organization data on diagnostic coding and reimbursement were reviewed. Alzheimer's disease (AD) is grossly undercoded. Few AD cases are recognized at an early stage. Only 13% of a group of patients receiving the AD therapy donepezil had AD as the primary diagnosis, and AD is rarely included as a primary or secondary DRG diagnosis when the condition precipitating admission to the hospital is caused by AD. In addition, AD is often not mentioned on death certificates, although it may be the proximate cause of death. There is only one ICD-9-CM code for AD-331.0-and no clinical modification codes, despite numerous complications that can be directly attributed to AD. Medicare carriers consider ICD-9 codes for senile dementia (290 series) to be mental health codes and pay them at a lower rate than medical codes. DRG coding is biased against recognition of ADRD as an acute, admitting diagnosis. The CPT code system is an impediment to quality of care for ADRD patients because the complex, time-intensive services ADRD patients require are not adequately, if at all, reimbursed. Also, physicians treating significant numbers of AD patients are at greater risk of audit if they submit a high frequency of complex codes. AD is grossly undercoded in acute hospital and outpatient care settings because of failure to diagnose, limitations of the coding system, and reimbursement issues. Such undercoding leads to a lack of recognition of the effect of AD and its complications on clinical care and impedes the development of better care management. We recommend continuing physician education on the importance of early diagnosis and care management of AD and its documentation through appropriate coding, expansion of the current ICD-9-CM codes for AD, more appropriate use of DRG coding for ADRD, recognition of the need for time-intensive services by ADRD patients that result in a higher frequency of use of complex CPT codes, and reimbursement for CPT codes that cover ADRD care management services.

Learning preferences of caregivers of asthmatic children.

BACKGROUND: People learn in different ways: visually, aurally, by reading/writing, and kinesthetically. In our clinic, we use color-coded Asthma Action Cards to educate our patients and their caregivers on asthma management. Our teaching is largely aural based, with the cards providing reading and visual stimulation and hands-on practice with devices offering kinesthetic stimulation. OBJECTIVE: We sought to determine the learning styles of the caregivers of our asthmatic children. METHODS: Caregivers in our Asthma/Allergy Clinic completed the Visual-Aural-Read/Write-Kinesthetic (VARK) questionnaire anonymously, and the responses were evaluated on the basis of previously validated scoring instructions. RESULTS: Analysis of 98 respondents showed that 42% had a single learning modality preference, and the remaining 58% were multimodal learners. Of those who reported a single mode of learning, 61% preferred kinesthetic, 27% preferred reading/writing, and less than 1% each preferred aural or visual stimuli. Of all 98 caregivers, 82% included kinesthetic as a learning preference, 59% included read/write, 50% included aural, and 41% included visual. CONCLUSION: The majority of caregivers preferred the kinesthetic learning method, whether as a single learning preference or in combination with other approaches. Incorporating kinesthetic methods of learning, such as role plays and problem-solving case scenarios, into standardized asthma education curricula may be beneficial to patients and families in terms of understanding and using their regimen.

Feasibility of intraoperative balloon angioplasty and additional stent placement of isolated stenosis of the brachiocephalic trunk.

OBJECTIVE: We sought to evaluate the feasibility and results of intraoperative balloon angioplasty and additional stent placement of isolated stenosis of the brachiocephalic trunk. PATIENTS AND METHODS: Between May 1993 and October 1996, we treated eight patients with local stenosis of the innominate artery. Seven lesions were situated in the proximal and one in the middle third of the brachiocephalic trunk. Five patients were men and three were women, with ages ranging from 55 to 72 years (mean 59.5 years). All stenoses provoked severe blood flow reduction and caused clinical symptoms. Procedures were performed in an operating suite with fluoroscopic imaging capabilities. Through an anterolateral cervical approach the right common carotid artery was surgically exposed and then clamped to avoid atheroembolization during the subsequent procedure. Retrograde catheterization was performed to reach the stenosis of the brachiocephalic trunk. The lesion was dilated with a balloon catheter and successively stented. Follow-up examinations (color-coded duplex sonography, accompanied by clinical inspection and systolic blood pressure) were scheduled every 6 months. RESULTS: In all patients the dilation of the stenosis of the innominate artery and the stent placement were successful without any side effects. No embolic events or other complications occurred. The postintervention angiography showed successfully dilated stenoses and patent stents in all cases. The technical success rate was 100%. CONCLUSIONS: On the basis of our preliminary data, we believe that, in selected patients, intraoperative balloon angioplasty of stenosis of the innominate artery with stent placement from the right common carotid artery approach is a safe and effective alternative to conventional operations.

[Model project on coding accuracy].

First experiences with the external evaluation of coding accuracy in view of the German DRG-System are reported. 387 randomised inpatient cases of three departments of a municipal hospital were evaluated. 1.648 diagnosis codes and 946 procedure codes were evaluated with complete clinical data. Before and after correction by the reviewers the cases were grouped (AR-DRG 4.1) and the casemix index of the sample was calculated. 45.9% to 56.7% of primary diagnosis in the department samples were rated as correct. 25.2% to 37.5% of secondary diagnosis were rated as correct, 8.3% to 14.2% were corrected and 49.2% to 60.5% were rated as not relevant with regard to the German coding standards. 7.2% to 22.7% of secondary diagnosis had to be completed in the data. Evaluation of procedure codes resulted in 54.2% to 65.7% accepted codes, 5.9% to 12.1% corrected codes and 23.1% to 39.9% not accepted with regard to the German coding standards. 30.8% to 37.0% of procedure codes had to be completed in the data. After review, remarkable shift in DRGs was seen and casemix index increased 6.9% in average (0.25-12.1%). General and department-specific implications for improvement of coding accuracy could be evaluated. Consequences of potential coding errors in a prospective payment system on DRG basis were seen under conditions of daily hospital practice. External evaluation of coding accuracy used in this study could be the methodological basis for further investigations on this topic.

Comparison of reliability of manual and computer-intensive methods for radiodensity measures of alveolar bone loss.

OBJECTIVE: To compare the reliability of radiodensity measurements made from dental radiographs with manual and a novel computer-intensive methods. METHODS: As part of a prospective study of postmenopausal women, a series of seven vertical bitewing radiographs were taken of 36 patients. One of each set of radiographs was repeated. The original and the corresponding duplicate radiographs were used in this study. Radiographs were digitized at 50 microns spatial resolution and 12-bit gray-scale resolution. For the Manual Method, original and duplicate radiographs were manually cropped to improve image homology, histogram matched and mean pixel gray-scale values determined for an alveolar bone ROI within each image. For the computer-intensive method, images were put into registration with ANALYZE software (Mayo Foundation, Rochester, MINN, USA), cropped automatically, histogram matched and color-coded on the basis of the per cent difference. Alveolar bone ROIs adjacent to clinical crowns and root surfaces whose color code indicated less than a 5% change were sampled. Method error (ME) and the coefficient of variation of method error (CVME) were calculated. RESULTS: With the Manual Method the SD between original and duplicate measures was 95.21 out of 4096 gray scale values; ME = 67.32; CVME = 3.78%. For the computer-intensive method, the corresponding values were 54.74, 38.71, and 2.29%. CONCLUSIONS: The new computer-intensive method resulted in a 40% improvement over the Manual Method in the precision of radiodensity measurements.

Intraoperative color-coded duplex sonography for localization of a distal middle cerebral artery aneurysm: technical case report.

OBJECTIVE AND IMPORTANCE: We describe the surgical treatment of a small, distal, middle cerebral artery (MCA) aneurysm, performed using intraoperative color-coded duplex sonography for localization. CLINICAL PRESENTATION: A 55-year-old man presented with a sudden intense headache. Computed tomographic scans revealed a subarachnoid hemorrhage. Angiography demonstrated two MCA aneurysms, one arising from the proximal bifurcation of the right MCA and the other from its distal bifurcation. TECHNIQUE: On Day 1, the proximal MCA aneurysm was clipped via the standard transsylvian approach. The distal MCA aneurysm was identified with the aid of color-coded duplex sonography and was successfully clipped with minimal additional dissection of the sylvian fissure. CONCLUSION: Color-coded duplex sonography provides a two-dimensional image of the brain parenchyma and color-coded flow imaging of cerebral vessels in real time. It may be used for rapid intraoperative localization of small, distally located, cerebral aneurysms.

Comparative psychopathology of women who experienced intra-familial versus extra-familial sexual abuse.

The Diagnostic Inventory of Personality and Symptoms (DIPS) was used to assess psychopathology in a clinical sample of 30 women with histories of intra-familial sexual victimization, 22 women with histories of extra-familial sexual victimization, and 30 women with no victimization experiences. The present study examines whether the relative/nonrelative issue is significant to the impact of sexual victimization experiences. A clinical comparison of two point code types indicated that both sexually abused groups could be characterized as suffering an Affective Depressed-Dissociative Disorder. However, profile shapes produced for the intra- and extra-familial abused groups differed. A discriminant function developed via step wise selection procedures incorporated 12 of the 14 scales, correctly classifying 94% of the individuals (49 of 52) as members of the extra or intra-familial groups. Profile analyses, discriminant analyses, clinically descriptive comparisons, and post hoc analyses of individual scales all revealed that psychopathology is much more evident in those who have experienced sexual abuse. Methodological considerations are highlighted and implications for treatment and research are addressed.

A comparison of multiple data sources to identify vaccinations for veterans with spinal cord injuries and disorders.

Monitoring vaccination activity requires regular access to information about patient vaccination status. This report describes our experience using multiple Department of Veterans Affairs (VA) data sources to determine availability and completeness of vaccination information for veterans with spinal cord injuries and disorders (SCI&D). Administrative and clinical databases were limited to coding vaccine administration, undercounted vaccinations, and were unable to account for whether the vaccine was offered and the reasons for nonreceipt. Medical record review provided more detail but was labor intensive and costly. Patient surveys provided the richest information but were costly, time-consuming, and based on a sample of patients. Agreement was poor between data sources. This report suggests that while VA is well positioned to use national databases for clinical care decisions and to inform policy, vaccination data were incomplete. Electronic records must include data that are consistently entered and validated before they can be useful for care management and decision making.

A coherent approach to health informatics education: results of the Dutch curriculum project.

From the beginning a coherent approach to health informatics education has been aimed for in our project to develop learning materials. The features are the thematic approach of the contents, the interrelationship of the modules and the didactical approach embedded in the learning materials. Following results have been achieved. Learning materials have been developed for the following themes: healthcare policy and management, delivery of professional care (specific for nursing and allied health), more generic themes such as electronic patient record, clinical decision making, classification and coding of healthcare data and knowledge based systems. Software made available by private companies has been selected for use in the learning modules. In specific cases the available software products did not match the criteria to support the learning materials. In these cases model applications have been developed that can be considered as forerunners for systems in practical use. Already some companies have expressed interest to adapt our home grown products for use in clinical practice. The modules are based on a model curriculum that has been developed by Aarts et al in 1995. New developments in healthcare have prompted modification of the contents of a few modules. For example, a module has been redefined to cover the important issue of logistics in healthcare. The module on patient education has been adapted to take into account the resources available on the Internet. Also, new insights in the effectiveness of computer-based patient education have been taken into account. The module on informatics for disabled persons has been focussed on computer-based aids and is being linked to the EU-project "Impact" aimed at increasing knowledge about assistive technology. However, the model curriculum has proved to be reasonable robust as a base for our project to develop learning materials for health informatics.

Amplitude coded-colour Doppler sonography in paediatric renal disease.

The aim of our study was to assess the ability of amplitude coded-colour Doppler sonography (ACDS) to depict altered perfusion in paediatric renal disease in a prospective study. Colour Doppler sonography (CDS) and ACDS examinations were performed in 180 renal units (90 patients; age range newborn to 16 years) with unilateral or bilateral renal disease (e.g. reflux nephropathy, renal scars, end-stage renal disease, ureteropelvic junction obstruction, urinary tract infection, renal failure, haemolytic uraemic syndrome, nephrotic syndrome, systemic lupus erythematosus (LE), renal biopsy, congenital dysplasia, tumour/infiltration). The ACDS results were compared with scintigraphy or CT as well as to clinical findings. Amplitude colour-coded Doppler sonography accurately demonstrated normal vasculature in 49 of 51 healthy kidneys (= 96%); 3 healthy kidneys could not be evaluated due to motion/artefacts. In 39 of 43 kidneys with focally altered perfusion ACDS could be performed and correctly depicted focally impaired vasculature/perfusion in 35 kidneys (= 89.7%). Seventy-three of 83 kidneys with diffusely impaired perfusion could be evaluated by ACDS and altered pattern was correctly depicted in 58 kidneys (= 79.4%), with an overall percentage of agreement of 87.1%. Amplitude CDS appears to be useful in infants and children. Compared with CDS it improves visualisation of especially focally impaired vasculature/perfusion and should be considered a valuable adjunct to conventional investigations.

The incidence of fibromyalgia and its associated comorbidities: a population-based retrospective cohort study based on International Classification of Diseases, 9th Revision codes.

BACKGROUND: The epidemiology of fibromyalgia is poorly defined. The incidence of fibromyalgia has not been determined using a large population base. Previous studies based on prevalence data demonstrated that females are 7 times more likely to have fibromyalgia than males and that the peak age for females is during the childbearing years. OBJECTIVE: We have calculated the incidence rate of fibromyalgia in a large, stable population and determined the strength of association between fibromyalgia and 7 comorbid conditions. METHODS: We conducted a retrospective cohort study of a large, stable health insurance claims database (62,000 nationwide enrollees per year). Claims from 1997 to 2002 were examined using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes to identify fibromyalgia cases (ICD code 729.1) and 7 predetermined comorbid conditions. RESULTS: A total of 2595 incident cases of fibromyalgia were identified between 1997 and 2002. Age-adjusted incidence rates were 6.88 cases per 1000 person-years for males and 11.28 cases per 1000 person-years for females. Females were 1.64 times (95% confidence interval = 1.59-1.69) more likely than males to have fibromyalgia. Patients with fibromyalgia were 2.14 to 7.05 times more likely to have one or more of the following comorbid conditions: depression, anxiety, headache, irritable bowel syndrome, chronic fatigue syndrome, systemic lupus erythematosus, and rheumatoid arthritis. CONCLUSION: Females are more likely to be diagnosed with fibromyalgia than males, although to a substantially smaller degree than previously reported, and there are strong associations for comorbid conditions that are commonly thought to be associated with fibromyalgia.

LOINC, a universal standard for identifying laboratory observations: a 5-year update.

The Logical Observation Identifier Names and Codes (LOINC) database provides a universal code system for reporting laboratory and other clinical observations. Its purpose is to identify observations in electronic messages such as Health Level Seven (HL7) observation messages, so that when hospitals, health maintenance organizations, pharmaceutical manufacturers, researchers, and public health departments receive such messages from multiple sources, they can automatically file the results in the right slots of their medical records, research, and/or public health systems. For each observation, the database includes a code (of which 25 000 are laboratory test observations), a long formal name, a "short" 30-character name, and synonyms. The database comes with a mapping program called Regenstrief LOINC Mapping Assistant (RELMA(TM)) to assist the mapping of local test codes to LOINC codes and to facilitate browsing of the LOINC results. Both LOINC and RELMA are available at no cost from http://www.regenstrief.org/loinc/. The LOINC medical database carries records for >30 000 different observations. LOINC codes are being used by large reference laboratories and federal agencies, e.g., the CDC and the Department of Veterans Affairs, and are part of the Health Insurance Portability and Accountability Act (HIPAA) attachment proposal. Internationally, they have been adopted in Switzerland, Hong Kong, Australia, and Canada, and by the German national standards organization, the Deutsches Instituts für Normung. Laboratories should include LOINC codes in their outbound HL7 messages so that clinical and research clients can easily integrate these results into their clinical and research repositories. Laboratories should also encourage instrument vendors to deliver LOINC codes in their instrument outputs and demand LOINC codes in HL7 messages they get from reference laboratories to avoid the need to lump so many referral tests under the "send out lab" code.

Great saphenous vein stripping with liberal use of subfascial endoscopic perforator vein surgery (SEPS).

This study is based on a unique registry of 632 patients who underwent great saphenous vein (GSV) stripping and liberal use of subfascial endoscopic perforator vein surgery (SEPS) for minimal to severe lower limb venous insufficiency. Clinical examinations and color-coded duplex scanning were performed on a randomly selected, manageable sample of 170 limbs to assess the affect of early SEPS on junctional (saphenofemoral [SFJ] and/or saphenopopliteal [SPJ]) and perforator vein (PV) insufficiencies and superficial varicosities at a median of 6.5 years. PV incompetence was present in 68 legs (40%), as the sole transfascial insufficiency in 28 limbs and combined with SFJ or SPJ incompetence in 40 limbs. Junction incompetence alone characterized an additional 38 limbs, bringing the total transfascial insufficiency prevalence to 62%. Superficial varicosities affected 46% of limbs. Overall CEAP clinical class was unimproved beyond preoperative values. PV incompetence was associated with higher CEAP and clinical venous severity scores than were junctional insufficiencies alone. We concluded that PV incompetence alone or combined with junctional insufficiency is associated with increased symptoms and disease progression. The prevalence of SFJ, SPJ, and PV incompetence (62%) and recurrent varicosities (46%) suggests that early use of SEPS does not prevent disease progression and offers no benefit over GSV stripping in the absence of deep vein insufficiency or threatened ulceration.

What if pediatric residents could bill for their outpatient services?

OBJECTIVE: We prospectively studied the potential of billing and coding practices of pediatric residents in outpatient clinics and extrapolated our results to assess the financial implications of billing inaccuracies. Using Medicare as a common measure of "currency," we also used the relative value unit (RVU) and ambulatory payment class methodologies as means of assessing the productivity and financial value of resident-staffed pediatric clinics. METHODS: Residents were asked to submit voluntarily shadow billing forms and documentation of outpatient clinic visits. Documentation of work was assessed by a blinded reviewer, and current procedure terminology evaluation and management codes were assigned. Comparisons between resident codes and calculated codes were made. Financial implications of physician productivity were calculated in terms of dollar amounts and RVUs. Resource intensity was measured using the ambulatory payment class methodology. RESULTS: A total of 344 charts were reviewed. Coding agreement for health maintenance visits was 86%, whereas agreement for acute care visits was 38%. Eighty-three percent of coding disagreement in the latter group was resulting from undercoding by residents. Errors accounted for a 4.79% difference in potential reimbursement for all visit types and a 19.10% difference for acute care visits. No significant differences in shadow billing discrepancies were found between different levels of training. Residents were predicted to generate $67 230, $87 593, and $96 072 in Medicare revenue in the outpatient clinic setting during each successive year of training. On average, residents generated 1.17 +/- 0.01 and 0.81 +/- 0.02 work RVUs for each health maintenance visit and office visit, respectively. Annual productivity from outpatient clinic settings was estimated at 548, 735, and 893 work RVUs in the postgraduate levels 1, 2, and 3, respectively. CONCLUSION: When pediatric residents are not trained adequately in proper coding practices, the potential for billing discrepancies is high and potential reimbursement differences may be substantial. Discussion of financial issues should be considered in curriculum development.
