I68.8 — Other cerebrovascular disorders in diseases classified elsewhere
I68.8 is a billable, specific ICD-10-CM code for other cerebrovascular disorders in diseases classified elsewhere. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- syphilitic cerebral aneurysm (A52.05)
Code first
The underlying condition must be sequenced before this code.
- underlying disease
Risk adjustment
I68.8 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
I68.8 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
