F44.0 — Dissociative amnesia
F44.0 is a billable, specific ICD-10-CM code for dissociative amnesia. 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.
Other codes that can never be billed with F44.0
These codes carry an Excludes1 note pointing at F44.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F44.0 alone.
- F04Amnestic disorder due to known physiological condition
Risk adjustment
F44.0 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:
- HCC 153 Personality Disorders; Anorexia/Bulimia Nervosa0.396 RAF
- HCC 153 Personality Disorders; Anorexia/Bulimia Nervosa0.396 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
F44.0 is named in 15 Medicare coverage policies — 14 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.

How F44.0 is indexed
