R44 — Other symptoms and signs involving general sensations and perceptions

Non-billable headerICD-10-CM

R44 is a non-billable header ICD-10-CM code for other symptoms and signs involving general sensations and perceptions. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

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

alcoholic hallucinations (F10.151, F10.251, F10.951)
hallucinations in drug psychosis (F11-F19 with fifth to sixth characters 51)
hallucinations in mood disorders with psychotic symptoms (F30.2, F31.5, F32.3, F33.3)
hallucinations in schizophrenia, schizotypal and delusional disorders (F20-F29)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

disturbances of skin sensation (R20.-)

Other codes that can never be billed with R44

These codes carry an Excludes1 note pointing at R44. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R44 alone.

H53.1Subjective visual disturbances

Risk adjustment

R44 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 R44

6 child codes. Green means billable.
