About M67.5

M67.5 is the ICD-10-CM diagnosis code for Plica syndrome. It belongs to category M67 (other disorders of synovium and tendon), 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 3 subcodes must be used instead.

Within M67 (other disorders of synovium and tendon), M67.5 is specifically for Plica syndrome. Related codes cover short Achilles tendon (acquired) (M67.0), Synovial hypertrophy, not elsewhere classified (M67.2), transient synovitis (M67.3), ganglion (M67.4), other specified disorders of synovium and tendon (M67.8), unspecified disorder of synovium and tendon (M67.9) and plantar fasciitis (M67.A).

To report this condition, pick the subcode that matches the documentation: M67.50 (unspecified knee), M67.51 (right knee) and M67.52 (left knee).

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