F06.8 — Other specified mental disorders due to known physiological condition
F06.8 is a billable, specific ICD-10-CM code for other specified mental disorders due to known physiological condition. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Epileptic psychosis NOS
- Obsessive-compulsive and related disorder due to a known physiological condition
- Organic dissociative disorder
- Organic emotionally labile [asthenic] disorder
Other codes that can never be billed with F06.8
These codes carry an Excludes1 note pointing at F06.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F06.8 alone.
- R41.3Other amnesia
Risk adjustment
F06.8 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
F06.8 is named in 19 Medicare coverage policies — 18 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.
