F44 — Dissociative and conversion disorders
Non-billable headerICD-10-CM
F44 is a non-billable header ICD-10-CM code for dissociative and conversion disorders. It cannot be billed on its own: choose one of the more specific child codes below.
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.
- malingering [conscious simulation] (Z76.5)
Includes
Conditions this code covers.
- conversion hysteria
- conversion reaction
- hysteria
- hysterical psychosis
Other codes that can never be billed with F44
These codes carry an Excludes1 note pointing at F44. 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 alone.
Risk adjustment
F44 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.
