M02 Postinfective and reactive arthropathies
All 121 codes in the M02 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 M02
None of the 121 codes is assigned a clinical group. None of the 121 is assigned a comorbidity subgroup. None can lead a claim. CMS attaches a code-first note to all 121.
Code first
CMS grouper convention 113, on all 121 codes. Code first:
- congenital syphilis [Clutton's joints] (A50.5)
- enteritis due to Yersinia enterocolitica (A04.6)
- infective endocarditis (I33.0)
- underlying disease, such as:
- viral hepatitis (B15-B19)
Every code in M02
Descriptions are CDC’s FY2027 wording; where CMS’s grouper abbreviates one, its form is shown beneath.
