M07.639 — Enteropathic arthropathies, unspecified wrist
Is M07.639 billable?
Yes, but M07.639 is an unspecified code. M07.639 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, M07.639 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting M07.639 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from M07
The conditions below can never be reported together with M07.639 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- psoriatic arthropathies (L40.5-)
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M07.639, but a patient may have both at the same time. When documentation supports it, M07.639 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)

- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Code also — inherited from M07
Two codes may be needed to describe the condition fully. Whether M07.639 is sequenced first depends on the reason for the encounter.
