Medicare program; revisions to payment policies and adjustments to the relative value units under the physician fee schedule for calendar year 1999--HCFA. Final rule with comment period.

This final rule makes several policy changes affecting Medicare Part B payment. The changes that relate to physicians' services include: resource-based practice expense relative value units (RVUs), medical direction rules for anesthesia services, and payment for abnormal Pap smears. Also, we are rebasing the Medicare Economic Index from a 1989 base year to a 1996 base year. Under the law, we are required to develop a resource-based system for determining practice expense RVUs. The Balanced Budget Act of 1997 (BBA) delayed, for 1 year, implementation of the resource-based practice expense RVUs until January 1, 1999. Also, BBA revised our payment policy for nonphysician practitioners, for outpatient rehabilitation services, and for drugs and biologicals not paid on a cost or prospective payment basis. In addition, BBA permits certain physicians and practitioners to opt out of Medicare and furnish covered services to Medicare beneficiaries through private contracts and permits payment for professional consultations via interactive telecommunication systems. Furthermore, we are finalizing the 1998 interim RVUs and are issuing interim RVUs for new and revised codes for 1999. This final rule also announces the calendar year 1999 Medicare physician fee schedule conversion factor under the Medicare Supplementary Medical Insurance (Part B) program as required by section 1848(d) of the Social Security Act. The 1999 Medicare physician fee schedule conversion factor is $34.7315.
