F33.2 is a billable ICD-10-CM diagnosis code for major depressive disorder, recurrent severe without psychotic features. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 885. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 12 closely related codes. Coders also document this condition as recurrent severe major depressive disorder co-occurrent with anxiety. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Depressive disorders.
For Medicare Advantage risk adjustment, F33.2 maps to CMS-HCC Category 155 (Major Depression, Moderate or Severe, without Psychosis) under the V28 model, adding a risk factor of about 0.299 for a community, non-dual, aged beneficiary in payment year 2027.

The ICD-10-CM code for major depressive disorder, recurrent severe without psychotic features is F33.2 (sometimes written as F332). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is F33.2 (Major depressive disorder, recurrent) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report major depressive disorder, recurrent severe without psychotic features on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does F33.2 group to?
When major depressive disorder, recurrent severe without psychotic features is the principal diagnosis on an inpatient stay, it groups to MS-DRG 885 (psychoses), which carries a relative weight of 1.3904. Higher weights mean higher Medicare reimbursement.
Is F33.2 a CC or MCC?
CMS lists F33.2 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 12 closely related codes in its exclusion list.
Can F33.2 be reported with a code from F31?
Not as a rule. The Excludes1 note at F33, which applies to F33.2, lists "bipolar disorder (F31.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What HCC is F33.2?
F33.2 (major depressive disorder, recurrent severe without psychotic features) maps to CMS-HCC Category 155 (Major Depression, Moderate or Severe, without Psychosis), commonly written as HCC 155, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 59 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 132.
Does F33.2 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, F33.2 adds a risk adjustment factor of about 0.299 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.108 to 0.316 depending on the payment segment). A more severe related category (HCC 151, HCC 152, HCC 153, and HCC 154) supersedes it when both are reported. See the full factor table on the HCC 155 category page.
