Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

sequelae of stroke (I69.3)
sequelae of traumatic intracranial injury (S06.-)

Other codes that can never be billed with I69.9

These codes carry an Excludes1 note pointing at I69.9. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I69.9 alone.

Risk adjustment

I69.9 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.

Code to one of these instead I69.9

8 child codes. Green means billable.
