Q31 — Congenital malformations of larynx
Is Q31 billable?
No — Q31 is a non-billable header code. Q31 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 7 billable codes beneath Q31.

Excludes1 — never code together
The conditions below can never be reported together with Q31 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 laryngeal stridor NOS (P28.89)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q31, but a patient may have both at the same time. When documentation supports it, Q31 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
