Q51 — Congenital malformations of uterus and cervix
Is Q51 billable?
No — Q51 is a non-billable header code. Q51 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 18 billable codes beneath Q51.

Excludes1 — never code together — inherited from Q50-Q56
The conditions below can never be reported together with Q51 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 17
The conditions below are not part of Q51, but a patient may have both at the same time. When documentation supports it, Q51 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
