Medicare program; update of ratesetting methodology, payment rates, payment policies, and the list of covered surgical procedures for ambulatory surgical centers effective October 1, 1998--HCFA. Proposed rule.

In this rule we propose to--Update the criteria for determining which surgical procedures can be appropriately and safely performed in an ambulatory surgical center (ASC); Make additions to and deletions from the current list of Medicare covered ASC procedures based on the revised criteria; Rebase the ASC payment rates using cost, charge, and utilization data collected by a 1994 survey of ASCs; Refine the ratesetting methodology that was implemented by a final notice published on February 8, 1990 in the Federal Register; Require that ASC payment, coverage, and wage index updates be implemented annually on January 1 rather than having these updates occur randomly throughout the year; Reduce regulatory burden; and Make several technical policy changes. This proposed rule implements requirements of section 1833(i)(1) and (2) of the Social Security Act.
