Excludes2 — not included here, but may coexist

Inclusion terms

Other codes that can never be billed with F63.3
These codes carry an Excludes1 note pointing at F63.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F63.3 alone.

Risk adjustment
F63.3 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.
