To examine the change in volume and costs of physician services for ophthalmic surgical procedures associated with physician fee cuts.
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.
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.
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.
研究与医生费用削减相关的眼科手术医生服务量和成本的变化。
作者分析了医疗保险人群5%随机样本的医生索赔（B部分）数据。比较了1988年和1991年眼科手术医生服务的数量、比率、平均允许收费和总成本。
1991年，医疗保险受益人接受了约310万例（每1000人中有98例）眼科手术，而1988年为230万例（每1000人中有76例）。数量增加了35%，比率增加了28%。这些服务的平均允许收费下降了26%（从每例1155美元降至852美元），两年的总成本均为26亿美元。
1988年至1991年眼科手术医生服务费用的降低与服务量的增加相关。两年间眼科手术医生服务的总成本保持一致。
