I70 Atherosclerosis

All 246 codes in the I70 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 I70

203 of the 246 codes group to Wound (118), MMTA - Cardiac and Circulatory (83) and MMTA - Other (2); 43 are assigned no clinical group. Comorbidity subgroups: 82 toward Diseases of arteries, arterioles, and capillaries with ulceration and non-pressure, chronic ulcers; 20 toward Atherosclerosis, includes Peripheral Vascular Disease, Aortic Aneurysms and Hypotension; 6 toward Non-Pressure Chronic Ulcers; 138 are assigned none. 203 of the 246 can lead a claim. CMS attaches a code-first note to 1 of the 246.

  • Diseases of arteries, arterioles, and capillaries with ulceration and non-pressure, chronic ulcers: can award the low comorbidity tier as a secondary diagnosis.
  • Atherosclerosis, includes Peripheral Vascular Disease, Aortic Aneurysms and Hypotension: counts toward the high comorbidity tier only in an interaction pair.
  • Non-Pressure Chronic Ulcers

Code first

CMS grouper convention 77, on I70.92. Code first:

  • atherosclerosis of arteries of the extremities (I70.2-, I70.3-, I70.4-, I70.5-, I70.6-, I70.7-)

Every code in I70
