F33.0 — Major depressive disorder, recurrent, mild
F33.0 is a billable, specific ICD-10-CM code for major depressive disorder, recurrent, mild. It is valid for submission on a claim.
Excludes1 inherited from the categories above F33.0
These are not written on F33.0, but they bind it: a note on a category applies to every code beneath it. Billing F33.0 with anything listed here is a denial.
Other codes that can never be billed with F33.0
These codes carry an Excludes1 note pointing at F33.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F33.0 alone.
Risk adjustment
F33.0 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.
Medicare coverage
F33.0 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.

How F33.0 is indexed
