What is ICD-10 code F32.5?

F32.5 is the ICD-10-CM diagnosis code for Major depressive disorder, single episode, in full remission. A first episode of major depression where all or nearly all symptoms have resolved. It belongs to the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99). F32.5 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F32.5 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. F32.5 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. F32.5 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

What is the V28 vs V24 difference for F32.5?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. F32.5 was a payment HCC under V24 (Major Depressive, Bipolar, and Paranoid Disorders) but the V28 recalibration removed it from the risk adjustment model. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting F32.5?

Ensure documentation clearly states the patient is in remission or symptom-free Monitor for relapse; if symptoms return, may need to change code to active depression Because F32.5 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Buddy Documentation Tip

HCC Buddy guidance

Prior documentation of major depressive disorder that met full criteria

Single episode confirmed with no prior episodes

Full remission documented — complete absence of depressive symptoms

Current medication status (continuing maintenance or tapering)

Audit Caution

Using full remission when any depressive symptoms remain

Coding as recurrent (F33.42) when this was truly a single episode

Dropping the diagnosis entirely during maintenance treatment visits

Not coding the condition when the patient is still on antidepressant medication

Is F32.5 an HCC code?

Yes. F32.5 maps to Major Depressive, Bipolar, and Paranoid Disorders under the V24 model but is not retained in V28.

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 F32.5

For F32.5 to 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 F32.5 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

F32.5 is the ICD-10-CM diagnosis code for major depressive disorder, single episode, in full remission. A first episode of major depression where all or nearly all symptoms have resolved. F32.5 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, F32.5 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.

Ensure documentation clearly states the patient is in remission or symptom-free. Because F32.5 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 F32.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Ensure documentation clearly states the patient is in remission or symptom-free
•Monitor for relapse; if symptoms return, may need to change code to active depression

Clinical Significance

Major depressive disorder, single episode, in full remission indicates complete resolution of depressive symptoms from a first major depressive episode. While the patient is currently asymptomatic, this diagnosis remains relevant for medical history and prognostic considerations, as a history of major depression increases lifetime recurrence risk. Continued monitoring during medication taper periods is standard of care.

Documentation Requirements

✓Prior documentation of major depressive disorder that met full criteria
✓Single episode confirmed with no prior episodes
✓Full remission documented — complete absence of depressive symptoms
✓Current medication status (continuing maintenance or tapering)
✓Follow-up plan for recurrence monitoring
