Q50.1 — Developmental ovarian cyst
Q50.1 is a billable, specific ICD-10-CM code for developmental ovarian cyst. It is valid for submission on a claim.
Other codes that can never be billed with Q50.1
These codes carry an Excludes1 note pointing at Q50.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q50.1 alone.
- N83.2Other and unspecified ovarian cysts
Risk adjustment
Q50.1 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
Q50.1 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
