About M93

M93 is the ICD-10-CM diagnosis code for other osteochondropathies. It belongs to block M91-M94 (Chondropathies) 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M93.0 ((nontraumatic)), M93.1 (adults), M93.2 (dissecans), M93.8 (osteochondropathies) and M93.9 (unspecified).

The conditions in its Excludes2 note aren't part of M93, but may be coded alongside it if the patient has both: osteochondrosis of spine (M42.-).

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