F45 — Somatoform disorders
F45 is a non-billable header ICD-10-CM code for somatoform 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.
- dissociative and conversion disorders (F44.-)
- factitious disorders (F68.1-, F68.A)
- hair-plucking (F63.3)
- lalling (F80.0)
- lisping (F80.0)
- malingering [conscious simulation] (Z76.5)
- nail-biting (F98.8)
- psychological or behavioral factors associated with disorders or diseases classified elsewhere (F54)
- sexual dysfunction, not due to a substance or known physiological condition (F52.-)
- thumb-sucking (F98.8)
- tic disorders (in childhood and adolescence) (F95.-)
- Tourette's syndrome (F95.2)
- trichotillomania (F63.3)
Other codes that can never be billed with F45
These codes carry an Excludes1 note pointing at F45. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F45 alone.
Risk adjustment
F45 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 history
F45 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
