Excludes1 — never code together — inherited from M67

The conditions below can never be reported together with M67.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

palmar fascial fibromatosis [Dupuytren] (M72.0)
tendinitis NOS (M77.9-)
xanthomatosis localized to tendons (E78.2)

Excludes2 — not included here — inherited from Chapter 13

The conditions below are not part of M67.9, but a patient may have both at the same time. When documentation supports it, M67.9 and the excluded code may both be reported.

arthropathic psoriasis (L40.5-)
certain conditions originating in the perinatal period (P04-P96)
certain infectious and parasitic diseases (A00-B99)
