About M02.1

M02.1 is the ICD-10-CM diagnosis code for Postdysenteric arthropathy. It belongs to category M02 (postinfective and reactive arthropathies), block M00-M02 (infectious arthropathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.

Within M02 (postinfective and reactive arthropathies), M02.1 is specifically for Postdysenteric arthropathy. Related codes cover arthropathy following intestinal bypass (M02.0), Postimmunization arthropathy (M02.2), Reiter's disease (M02.3), other reactive arthropathies (M02.8) and reactive arthropathy, unspecified (M02.9).

To report this condition, pick the subcode that matches the documentation: M02.10 (unspecified site), M02.11 (shoulder), M02.12 (elbow), M02.13 (wrist), M02.14 (hand), M02.15 (hip), M02.16 (knee), M02.17 (ankle and foot) and 2 more.

Code first underlying disease, such as: congenital syphilis [Clutton's joints] (A50.5), enteritis due to Yersinia enterocolitica (A04.6), infective endocarditis (I33.0) and viral hepatitis (B15-B19).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
