F45.8 — Other somatoform disorders
F45.8 is a billable, specific ICD-10-CM code for other somatoform 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.
- sleep related teeth grinding (G47.63)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Psychogenic dysmenorrhea
- Psychogenic dysphagia, including 'globus hystericus'
- Psychogenic pruritus
- Psychogenic torticollis
- Somatoform autonomic dysfunction
- Teeth grinding
Other codes that can never be billed with F45.8
These codes carry an Excludes1 note pointing at F45.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F45.8 alone.
Risk adjustment
F45.8 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
F45.8 is named in 15 Medicare coverage policies — 13 listing it as supporting medical necessity, and 2 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
