I97 Intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified

All 39 codes in the I97 family, with the PDGM clinical group, comorbidity subgroup and primary-position rule CMS assigns, read from the CMS grouper crosswalk v07.2.26 and the CDC FY2027 code file.

What CMS assigns to I97

All 39 codes group to MMTA - Cardiac and Circulatory (38) and Wound (1). 1 of the 39 counts toward the Varicose Veins and Lymphedema comorbidity subgroup; 38 are assigned none. Every code can lead a claim.

  • Varicose Veins and Lymphedema: can award the low comorbidity tier as a secondary diagnosis.
