F33 — Major depressive disorder, recurrent
F33 is a non-billable header ICD-10-CM code for major depressive disorder, recurrent. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Includes
Conditions this code covers.
- recurrent episodes of depressive reaction
- recurrent episodes of endogenous depression
- recurrent episodes of major depression
- recurrent episodes of psychogenic depression
- recurrent episodes of reactive depression
- recurrent episodes of seasonal affective disorder
- recurrent episodes of seasonal depressive disorder
- recurrent episodes of vital depression
Other codes that can never be billed with F33
These codes carry an Excludes1 note pointing at F33. 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 alone.
Risk adjustment
F33 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.
The condition this code belongs to
Every code for the condition on one page, which one applies when, and the mistake coders make with it.
