G90.01 — Carotid sinus syncope
G90.01 is a billable, specific ICD-10-CM code for carotid sinus syncope. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Carotid sinus syndrome
Other codes that can never be billed with G90.01
These codes carry an Excludes1 note pointing at G90.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G90.01 alone.
- R55Syncope and collapse
Risk adjustment
G90.01 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
G90.01 is named in 23 Medicare coverage policies — 23 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
