N92.1 — Excessive and frequent menstruation with irregular cycle
N92.1 is a billable, specific ICD-10-CM code for excessive and frequent menstruation with irregular cycle. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Irregular intermenstrual bleeding
- Irregular, shortened intervals between menstrual bleeding
- Menometrorrhagia
- Metrorrhagia
Other codes that can never be billed with N92.1
These codes carry an Excludes1 note pointing at N92.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N92.1 alone.
- N92.6Irregular menstruation, unspecified
Risk adjustment
N92.1 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
N92.1 is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
