N40 — Benign prostatic hyperplasia
Is N40 billable?
No — N40 is a non-billable header code. N40 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 4 billable codes beneath N40.

Excludes1 — never code together
The conditions below can never be reported together with N40 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
The conditions below are not part of N40, but a patient may have both at the same time. When documentation supports it, N40 and the excluded code may both be reported.
