Common Mistakes
Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.
Is F33.40 an HCC code?
Yes. F33.40 maps to Major Depressive, Bipolar, and Paranoid Disorders under the V24 model but is not retained in V28.

HCC Category Mapping
Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for F33.40
For F33.40to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed F33.40 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
F33.40 is the ICD-10-CM diagnosis code for major depressive disorder, recurrent, in remission, unspecified. A condition where a person experiences repeated episodes of major depression and is currently in remission (symptoms have improved but may not be completely gone). F33.40 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mood [affective] disorders (f30-f39).
Under the older CMS-HCC V24 model, F33.40 maps to Major Depressive, Bipolar, and Paranoid Disorders (HCC 59) with a community, non-dual, aged base RAF weight of 0.309. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
MDD, recurrent, in remission, unspecified, recurrent MDD history with documented remission at the current encounter, partial vs full not specified. Document the remission status and the underlying recurrent MDD history accurately. Because F33.40 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F33.40 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •MDD, recurrent, in remission, unspecified, recurrent MDD history with documented remission at the current encounter, partial vs full not specified. Document the remission status and the underlying recurrent MDD history accurately.
- •Do not assign a remission code to claim a depression HCC. Under V28, recurrent MDD in remission does NOT map to a payment HCC, so a remission code cannot substitute for an active moderate/severe MDD diagnosis when the patient currently meets those criteria.
- •F33.40 does NOT map to a V28 payment HCC. The V28 depression HCC (155) requires current moderate or severe MDD without psychosis (F33.1/F33.2); remission codes were excluded. Code remission honestly for chart accuracy, not for RAF capture.
Clinical Significance
Major depressive disorder, recurrent, in remission, unspecified indicates the patient has a history of multiple depressive episodes and is currently in remission, but the type of remission (partial vs full) is not documented. While the patient is stable, the recurrent history necessitates ongoing monitoring and maintenance treatment. This code should prompt a query to determine partial versus full remission status.
Documentation Requirements
- ✓Documented history of recurrent major depressive disorder
- ✓Current remission status documented by provider
- ✓Provider should be queried for partial versus full remission specification
- ✓Maintenance medication regimen documented
- ✓Follow-up monitoring plan
Commonly Confused Codes
- •F33.41: Major depressive disorder, recurrent, partial remission: Residual symptoms present
- •F33.42: Major depressive disorder, recurrent, full remission: Complete symptom resolution
- •F32.4: Major depressive disorder, single episode, partial remission: Only one prior episode
- •F33.9: Major depressive disorder, recurrent, unspecified: Does not specify remission status
