F20 — Schizophrenia
F20 is a non-billable header ICD-10-CM code for schizophrenia. 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.
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.
Use additional code
Add a secondary code to capture the detail described below.
- code, if applicable, to identify:
- other specified cognitive deficit (R41.84-)
Other codes that can never be billed with F20
These codes carry an Excludes1 note pointing at F20. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F20 alone.
Risk adjustment
F20 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 F20
7 child codes. Green means billable.
