M71.3Other bursal cyst

M71.3 is the ICD-10-CM diagnosis code for other bursal cyst. It belongs to category M71 (other bursopathies), block M70-M79 (other soft tissue disorders) 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 9 subcodes must be used instead.

Within M71, choose M71.3 (Other bursal cyst) only when documentation doesn't support a more specific option: abscess of bursa (M71.0), other infective bursitis (M71.1), Synovial cyst of popliteal space [Baker] (M71.2), calcium deposit in bursa (M71.4), other bursitis, not elsewhere classified (M71.5), other specified bursopathies (M71.8) and Bursopathy, unspecified (M71.9).

To report this condition, pick the subcode that matches the documentation: M71.30 (unspecified site), M71.31 (shoulder), M71.32 (elbow), M71.33 (wrist), M71.34 (hand), M71.35 (hip), M71.37 (ankle and foot), M71.38 (other site) and 1 more.

Don't report M71.3 together with the conditions in its Excludes1 note: synovial cyst with rupture (M66.1-).

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