F22 — Delusional disorders
F22 is a billable, specific ICD-10-CM code for delusional disorders. It is valid for submission on a claim.
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.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Delusional dysmorphophobia
- Involutional paranoid state
- Paranoia
- Paranoia querulans
- Paranoid psychosis
- Paranoid state
- Paraphrenia (late)
- Sensitiver Beziehungswahn
Other codes that can never be billed with F22
These codes carry an Excludes1 note pointing at F22. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F22 alone.
- F20.0Paranoid schizophrenia
Risk adjustment
F22 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:
- HCC 152 Psychosis, Except Schizophrenia0.484 RAF
- HCC 152 Psychosis, Except Schizophrenia0.484 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
F22 is named in 17 Medicare coverage policies — 16 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
