B91 — Sequelae of poliomyelitis
B91 is a billable, specific ICD-10-CM code for sequelae of poliomyelitis. 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.
- postpolio syndrome (G14)
Other codes that can never be billed with B91
These codes carry an Excludes1 note pointing at B91. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading B91 alone.
- G14Postpolio syndrome
Risk adjustment
B91 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
B91 is named in 20 Medicare coverage policies — 20 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How B91 is indexed
