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.
- alcohol related insomnia (F10.182, F10.282, F10.982)
- drug-related insomnia (F11.182, F11.282, F11.982, F13.182, F13.282, F13.982, F14.182, F14.282, F14.982, F15.182, F15.282, F15.982, F19.182, F19.282, F19.982)
- idiopathic insomnia (F51.01)
- insomnia due to a mental disorder (F51.05)
- insomnia not due to a substance or known physiological condition (F51.0-)
- nonorganic insomnia (F51.0-)
- primary insomnia (F51.01)
- sleep apnea (G47.3-)
Other codes that can never be billed with G47.0
These codes carry an Excludes1 note pointing at G47.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G47.0 alone.
Risk adjustment
G47.0 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.
