But Dr. Kellerman praised the move by CMS to change the way it determines practice expense RVUs, which include the direct and indirect costs associated with a procedure. Under the new system, practice expenses will take into account practice expense data from eight specialties. The changes to the practice expense RVUs are being phased in over 4 years.
Although primary care specialties make out relatively well under the RVU changes, other specialties will face deep cuts under them. For example, CMS estimates that cardiologists will face a 1% cut in allowed charges in 2007, and a 5% cut in 2010 based on changes to the work and practice expense RVUs.
