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.
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.
