N39.491 — Coital incontinence
N39.491 is a billable, specific ICD-10-CM code for coital incontinence. It is valid for submission on a claim.
Excludes1 inherited from the categories above N39.491
These are not written on N39.491, but they bind it: a note on a category applies to every code beneath it. Billing N39.491 with anything listed here is a denial.
Excludes2 inherited from the categories above N39.491
Also inherited, and the opposite of Excludes1: these conditions are not part of N39.491, but a patient can have both, so you may code both.
Risk adjustment
N39.491 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Medicare coverage
N39.491 is named in 16 Medicare coverage policies — 16 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
