M84.439G — Pathological fracture, unspecified ulna and radius, subsequent encounter for fracture with delayed healing
Is M84.439G billable?
Yes, but M84.439G is an unspecified code. M84.439G is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, M84.439G 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 M84.439G — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from M84.4
The conditions below can never be reported together with M84.439G on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 13

- traumatic fracture of bone-see fracture, by site
Excludes2 — not included here — inherited from M84.4
The conditions below are not part of M84.439G, but a patient may have both at the same time. When documentation supports it, M84.439G and the excluded code may both be reported.
