M71.4Calcium deposit in bursa

M71.4 is the ICD-10-CM diagnosis code for calcium deposit in bursa. 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 (other bursopathies), M71.4 is specifically for calcium deposit in bursa. Related codes cover abscess of bursa (M71.0), other infective bursitis (M71.1), Synovial cyst of popliteal space [Baker] (M71.2), other bursal cyst (M71.3), 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: M71.40 (unspecified site), M71.42 (elbow), M71.43 (wrist), M71.44 (hand), M71.45 (hip), M71.46 (knee), M71.47 (ankle and foot), M71.48 (other site) and 1 more.

The conditions in its Excludes2 note aren't part of M71.4, but may be coded alongside it if the patient has both: calcium deposit in bursa of shoulder (M75.3).

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