Some Aspects of Ambulatory Care under Medicaid in New York City.
This report analyzes claims submitted to New York City Medicaid in order to profile patients' use of ambulatory care services and to assess charges of suspect practices by both providers and patients. It finds that claims provide a valuable but limited source of information. Although individual physicians and hospital clinics are often viewed as alternative sources of care, many Medicaid cases see both. Total costs for ambulatory care are similar for physician and clinic users even though clinic visits cost three times as much as physician visits. Some findings are consistent with suspect practices; some are not. More research is needed. 120 pp. Ref.
