F20Schizophrenia

Non-billable headerICD-10-CM

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.

  • R40.1Stupor
  • R44Other symptoms and signs involving general sensations and perceptions
  • R46Symptoms and signs involving appearance and behavior
  • F25Schizoaffective disorders
  • F22Delusional disorders
  • F53Mental and behavioral disorders associated with the puerperium, not elsewhere classified

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.
