M02.8Other reactive arthropathies

M02.8 is the ICD-10-CM diagnosis code for other reactive arthropathies. 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, choose M02.8 (Other reactive arthropathies) only when documentation doesn't support a more specific option: arthropathy following intestinal bypass (M02.0), Postdysenteric arthropathy (M02.1), Postimmunization arthropathy (M02.2), Reiter's disease (M02.3) and reactive arthropathy, unspecified (M02.9).

To report this condition, pick the subcode that matches the documentation: M02.80 (unspecified site), M02.81 (shoulder), M02.82 (elbow), M02.83 (wrist), M02.84 (hand), M02.85 (hip), M02.86 (knee), M02.87 (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.
