About M14

M14 is the ICD-10-CM diagnosis code for arthropathies in other diseases classified elsewhere. It belongs to 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 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M14.6 (joint) and M14.8 (elsewhere).

Don't report M14 together with the conditions in its Excludes1 note: diabetes mellitus (E08-E13 with .61-), hematological disorders (M36.2-M36.3), hypersensitivity reactions (M36.4), neoplastic disease (M36.1) and 5 more.

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