D49.89 — Neoplasm of unspecified behavior of other specified sites
Is D49.89 billable?
Yes, but D49.89 is an unspecified code. D49.89 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D49.89 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 D49.89 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from D49.8
The conditions below can never be reported together with D49.89 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 D49
The conditions below are not part of D49.89, but a patient may have both at the same time. When documentation supports it, D49.89 and the excluded code may both be reported.
