About M11.0
M11.0 is the ICD-10-CM diagnosis code for Hydroxyapatite deposition disease. It belongs to category M11 (other crystal arthropathies), block M05-M14 (inflammatory polyarthropathies) 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 M11 (other crystal arthropathies), M11.0 is specifically for Hydroxyapatite deposition disease. Related codes cover familial chondrocalcinosis (M11.1), other chondrocalcinosis (M11.2), other specified crystal arthropathies (M11.8) and crystal arthropathy, unspecified (M11.9).
To report this condition, pick the subcode that matches the documentation: M11.00 (unspecified site), M11.01 (shoulder), M11.02 (elbow), M11.03 (wrist), M11.04 (hand), M11.05 (hip), M11.06 (knee), M11.07 (ankle and foot) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
