To describe physician fee patterns under a national program, we analyzed physician reimbursement rates for 39 medical procedures for 292 local Medicare reimbursement areas. The results indicate that the maximum prevailing charge for each procedure generally ranged from three to 10 times the minimum charge. Prevailing charges, however, clustered around the mean (coefficient of variation less than 0.50) in 37 of the 39 fee distributions for general practitioners and specialists. Although differences (P less than 0.05) existed between mean general practitioner and specialist charges for 27 of the 39 procedures, these differences were generally less than 10%.
为描述一项全国性计划下的医生收费模式，我们分析了292个地方医疗保险报销区域中39种医疗程序的医生报销率。结果表明，每种程序的最高现行收费通常是最低收费的三到十倍。然而，在全科医生和专科医生的39种费用分布中，有37种的现行收费集中在均值附近（变异系数小于0.50）。虽然39种程序中有27种在全科医生和专科医生的平均收费之间存在差异（P小于0.05），但这些差异通常小于10%。
