title: The use and costs of physician services for ophthalmic surgical procedures in 1988 and 1991.
abstract: OBJECTIVE
  To examine the change in volume and costs of physician services for ophthalmic surgical procedures associated with physician fee cuts.
  
  
  METHODS
  The authors analyzed the physician claims (Part B) data for a 5% random sample of the Medicare population. Number, rate, average allowed charge, and total cost of physician services for ophthalmic surgical procedures were compared for 1988 and 1991.
  
  
  RESULTS
  An estimated 3.1 million (98 per 1000) ophthalmic surgical procedures were performed on Medicare beneficiaries in 1991, compared with 2.3 million (76 per 1000) in 1988. There was a 35% increase in number and a 28% increase in rate. The average allowed charge for these services decreased by 26% ($1155 vs $852 per procedure), with an overall cost of $2.6 billion in both years.
  
  
  CONCLUSIONS
  A reduction in fee for physician services for ophthalmic surgical procedures from 1988 to 1991 was associated with an increase in the volume of the services. The overall costs of physician services for ophthalmic surgical procedures remained consistent between the two years.
