Coverage of PET Scans for Myocardial Viability

60.9 - Coverage of PET Scans for Myocardial Viability (Rev.10881; Issued: 08-06-2021; Effective: 09-07-2021; Implementation: 09-07- 2021) FDG PET is covered for the determination of myocardial viability following an inconclusive single photon computed tomography test (SPECT) from July 1, 2001, through September 30, 2002. Only full ring scanners are covered as the scanning medium for this service from July 1, 2001, through December 31, 2001. However, as of January 1, 2002, full and partial ring scanners are covered for myocardial viability following an inconclusive SPECT. Beginning October 1, 2002, Medicare will cover FDG PET for the determination of myocardial viability as a primary or initial diagnostic study prior to revascularization, and will continue to cover FDG PET when used as a follow-up to an inconclusive SPECT. However, if a patient received a FDG PET study with inconclusive results, a follow-up SPECT is not covered. FDA full and partial ring PET scanners are covered. In the event that a patient receives a SPECT with inconclusive results, a PET scan may be performed and covered by Medicare. However, a SPECT is not covered following a FDG PET with inconclusive results. See the Medicare National Coverage Determinations Manual, Section 220.6 for specific frequency limitations for Myocardial Viability following an inconclusive SPECT. Documentation that these conditions are met should be maintained by the referring provider as part of the beneficiary’s medical record.
