To determine whether family physicians provide different ambulatory care to patients with health insurance from managed care organization (MCO) versus fee-for-service (FFS) plans. Multimethod cross-sectional observational study. A total of 4454 patients made office visits to 138 family physicians in northeastern Ohio. Direct observation with the Davis Observation Code and a structured checklist were used to assess the process of care. Patient satisfaction was measured with the Medical Outcomes Study 9-Item Visit Rating Form. Among 1588 patients with MCO insurance and 876 with FFS insurance, no differences were noted in the number of visits per year, length of visits, percentage of visits for well care, or the percentage of visits in which medicines were prescribed in analyses controlling for patient mix. Visits by patients with MCO insurance were more likely to involve referrals to another physician than visits by patients with FFS insurance. Patient satisfaction and time use during visits were comparable for the 2 groups. Managed care insurance appears to increase involvement of the primary care provider in the referral process. However, in a healthcare market with moderate managed care penetration in which the same physicians see patients with different types of insurance, the process of care is affected little by type of insurance coverage.

To compare the concordance of family physicians' billing for evaluation and management services with medical record documentation. Multi-method, cross-sectional observation study. Eighty-four family practices in northeast Ohio. Four thousand fifty-four outpatients visiting 138 family physicians. The degree of concordance between evaluation and management Current Procedural Terminology codes billed by physicians, with those codes assigned by trained research nurses using American Medical Association criteria to code medical records for the same visits. Discrepancies between the multifactorial nature of family practice outpatient visits and the Current Procedural Terminology coding criteria, which dictate overcoding for depth rather than breadth, made coding difficult (multiple-rater kappa statistic between research nurses = 0.36). Among 4137 outpatient visits with complete billing information, 57% of the Current Procedural Terminology codes generated by medical record review were concordant with the actual billing code assigned by physicians. Undercoding and overcoding occurred at a similar frequency (21% and 19%, respectively) and differed by more than 1 code in fewer than 4% of visits. Visits by new patients were more likely to be inaccurately coded than visits by established patients. Record documentation by community family physicians largely reflects the level of services billed using evaluation and management codes. Undercoding is as common as overcoding. Efforts from regulatory agencies should be redirected from penalizing physicians for overcoding to focusing on the development of coding criteria that reflect the multifactorial nature of outpatient primary care practice.

Little is known about the accuracy of family physicians' use of the Current procedural Terminology (CPT) coding scheme for office visits, despite increased administrative oversight of Medicare billing practices. In addition, the patient and visit characteristics that are associated with over- and undercoding are not well understood. This study compared coding for evaluation and management (E&M) services billed for 3791 visits to 138 family physicians with the codes assigned by trained research nurses using direct observation. We calculated the degree to which the codes for E&M were concordant with the observer-assigned codes. Analysis of variance and logistic regression were used to examine the association of visit and patient characteristics with discordance between billed and observer-assigned CPT codes. Billing codes were concordant for 55% of encounters. Discordance was evenly distributed between under- and overcoding. Concordance of billed and observed codes was greatest for patients with indemnity insurance. Undercoding increased with longer visit length and a smaller percentage of the visit spent planning treatment. Overcoding was more common during visits with a greater percentage of time spent chatting, planning treatment, and delivering preventive services. Family physicians are generally accurate in their billing procedures. The findings on patient and visit characteristics associated with over- or undercoding may be used by practicing clinicians to enhance the accuracy of their coding and billing procedures.

Many physicians today are employed by another physician, group, hospital, HMO, or other organization. However, the differences in the characteristics, practice patterns, and patient outcomes of self-employed and employed physicians are not well understood. The practices of 108 community family physicians in northeast Ohio were assessed using a multimethod cross-sectional design. Physician characteristics were assessed by questionnaire. Direct observation of 3536 consecutive patient visits was used to measure time use and the delivery of preventive services recommended by the US Preventive Services Task Force. Patient satisfaction was assessed with the Medical Outcomes Study (MOS) 9-item Visit Rating Form. Employed physicians were more likely to be female, in group practice, work fewer hours, and see fewer patients. Job satisfaction was similar between the two groups, but employed physicians reported greater satisfaction with leisure and family time. Employed physicians spent more time per patient visit, scheduled a larger percentage of well-care visits, and were more likely to refer to specialists. Employed physicians also spent a greater proportion of their patients' visit time performing history-taking and eliciting family information, and a lesser proportion of time on physical examination, planning treatment, providing health education, and chatting. Recommended screening and health habits counseling preventive services were more likely to be delivered by employed physicians. Patient satisfaction was similar for the two groups. Primary care physician characteristics and practice patterns differ by employment status. The consequences of the trend toward a largely employed physician workforce as reported in this study should be carefully considered.
