Medicare Program; Revisions to Payment Policies Under the Physician Fee Schedule for Calendar Year 2001

This final rule with comment period makes several changes affecting Medicare Part B payment. The changes include: refinement of resource-based practice expense relative value units (RVUs); the geographic practice cost indices; resource-based malpractice RVUs; critical care RVUs; care plan oversight and physician certification and recertification for home health services; observation care codes; ocular photodynamic therapy and other ophthalmological treatments; electrical bioimpedance; antigen supply; and the implantation of ventricular assist devices. This rule also addresses the comments received on the May 3, 2000 interim final rule on the supplemental survey criteria and makes modifications to the criteria for data submitted in 2001. Based on public comments we are withdrawing our proposals related to the global period for insertion, removal, and replacement of pacemakers and cardioverter defibrillators and low intensity ultrasound. This final rule also discusses or clarifies the payment policy for incomplete medical direction, pulse oximetry services, outpatient therapy supervision, outpatient therapy caps, HCPCS "G" Codes, and the second 5-year refinement of work RVUs for services furnished beginning January 1, 2002. In addition, we are finalizing the calendar year (CY) 2000 interim physician work RVUs and are issuing interim RVUs for new and revised codes for CY 2001. We are making these changes to ensure that our payment systems are updated to reflect changes in medical practice and the relative value of services. This final rule also announces the CY 2001 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 2001 Medicare physician fee schedule conversion factor is $38.2581.
