About M71.1

M71.1 is the ICD-10-CM diagnosis code for other infective bursitis. 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 10 subcodes must be used instead.

Within M71, choose M71.1 (Other infective bursitis) only when documentation doesn't support a more specific option: abscess of bursa (M71.0), Synovial cyst of popliteal space [Baker] (M71.2), other bursal cyst (M71.3), 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: M71.10 (unspecified site), M71.11 (shoulder), M71.12 (elbow), M71.13 (wrist), M71.14 (hand), M71.15 (hip), M71.16 (knee), M71.17 (ankle and foot) and 2 more.

Use an additional code (B95.-, B96.-) to identify causative organism.

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