Excludes1 inherited from the categories above F06.34
These are not written on F06.34, but they bind it: a note on a category applies to every code beneath it. Billing F06.34 with anything listed here is a denial.
Excludes2 inherited from the categories above F06.34
Also inherited, and the opposite of Excludes1: these conditions are not part of F06.34, but a patient can have both, so you may code both.

Risk adjustment
F06.34 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
F06.34 is named in 20 Medicare coverage policies — 19 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.
