R41.8 — Other symptoms and signs involving cognitive functions and awareness
R41.8 is a non-billable header ICD-10-CM code for other symptoms and signs involving cognitive functions and awareness. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above R41.8
These are not written on R41.8, but they bind it: a note on a category applies to every code beneath it. Billing R41.8 with anything listed here is a denial.
Other codes that can never be billed with R41.8
These codes carry an Excludes1 note pointing at R41.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R41.8 alone.
Risk adjustment
R41.8 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.
Code history
R41.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
