Billable / specific codeICD-10-CM

F32.4 is a billable, specific ICD-10-CM code for major depressive disorder, single episode, in partial remission. It is valid for submission on a claim.

Risk adjustment

F32.4 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.

F32.4 is named in 36 Medicare coverage policies 35 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.
