Q30.9 — Congenital malformation of nose, unspecified
Is Q30.9 billable?
Yes, but Q30.9 is an unspecified code. Q30.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Q30.9 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 Q30.9 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from Q30
The conditions below can never be reported together with Q30.9 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital deviation of nasal septum (Q67.4)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q30.9, but a patient may have both at the same time. When documentation supports it, Q30.9 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
