The following information was posted in the November 27, 2007, Outpatient Prospective Payment System (OPPS) final rule at www.cms.gov.
Cardiac rehabilitation services
For CY 2008, CMS did not finalize the proposal to establish two new G-codes to report cardiac rehabilitation services. Instead, CMS will continue to use CPT codes 93797, Physician services for outpatient cardiac rehabilitation; without continuous ECG monitoring (per session), and 93798, Physician services for outpatient cardiac rehabilitation; with continuous ECG monitoring (per session), for these services. Beginning in CY 2008, CMS will allow hospitals to report more than one unit per day, if more than one cardiac rehabilitation session, lasting at least one hour each, is provided on the same day. CMS will monitor the claims data to ensure that utilization of cardiac rehabilitation services remains appropriate.
