F44.5 — Conversion disorder with seizures or convulsions
F44.5 is a billable, specific ICD-10-CM code for conversion disorder with seizures or convulsions. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Conversion disorder with attacks or seizures
- Dissociative convulsions
Other codes that can never be billed with F44.5
These codes carry an Excludes1 note pointing at F44.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F44.5 alone.
Risk adjustment
F44.5 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.
Medicare coverage
F44.5 is named in 23 Medicare coverage policies — 22 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.
