About M67

M67 is the ICD-10-CM diagnosis code for other disorders of synovium and tendon. It belongs to block M65-M67 (disorders of synovium and tendon) 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: M67.0 ((acquired)), M67.2 (classified), M67.3 (synovitis), M67.4 (ganglion), M67.5 (syndrome), M67.8 (tendon), M67.9 (tendon) and M67.A (fasciitis).

Don't report M67 together with the conditions in its Excludes1 note: palmar fascial fibromatosis [Dupuytren] (M72.0), tendinitis NOS (M77.9-) and xanthomatosis localized to tendons (E78.2).

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