We examined changes in copayments and coinsurance for covered benefits. Data on plan benefits were obtained from the employer survey in the Health Care for Communities Study, conducted between July 1999 and July 2000 (2). Data for earlier years were obtained from the Bureau of Labor Statistics (3). Copayments are a fixed dollar amount that the patient pays for each service, regardless of the service's cost. Coinsurance, on the other hand, requires the patient to pay a fixed proportion of the total cost of the visit.
