What is ICD-10 code F32.A?

F32.A is the ICD-10-CM diagnosis code for Depression, unspecified. It belongs to the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99). F32.A is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F32.A 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.A 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.A 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.

Which HCC does F32.A map to under V28?

F32.A does not map to a CMS-HCC V28 payment category. Check the current CMS-HCC V28 model file for payment year 2026 rather than an older V24 tip sheet.

What does F32.A pay in RAF?

F32.A has no separately stated V28 community RAF weight. If it is not a V28 payment HCC, it adds nothing to a community RAF score.

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

F32.A does not map to a payment HCC under either the CMS-HCC V28 risk adjustment model or the older V24 model. V28 reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition. Because neither community model rewards F32.A with a risk adjustment factor, it contributes zero to a Medicare Advantage beneficiary's V28/V24 community RAF score in either version. It does, however, map under the Part D RxHCC model (Major Depressive Disorder and Other Mood Disorders), which affects the ESRD and/or Part D (RxHCC) risk scores. Coders should check whether provider documentation supports a more specific child code that does map to a community payment HCC.

What documentation supports F32.A?

Query the provider if more specific information is available, such as severity level (mild, moderate, severe) or episode type (single vs. recurrent), as more specific F32 codes may be more appropriate Do not use this code if the depression is clearly documented as mild (F32.0), moderate (F32.1), or severe (F32.2, F32.3), or if it is a recurrent depressive disorder (F33 codes) F32.A is not a CMS-HCC payment code, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Depression, unspecified

This code represents depression that has been diagnosed but the specific type or severity level has not been documented or specified by the healthcare provider. It is used when a patient has depressive symptoms but the clinical details needed to assign a more specific depression code are not available.

Depression, unspecified is the least specific depression code, used when the provider documents depression without confirming major depressive disorder criteria or specifying the type and severity.

Buddy Documentation Tip

HCC Buddy guidance

Provider documentation of depression as a diagnosis or clinical concern

If possible, query provider to determine: Does this meet MDD criteria? Is this a single or recurrent episode? What is the severity?

Current treatment for depression documented

Symptoms described even if not meeting full MDD criteria

Audit Caution

HCC Buddy guidance

Using this code when the provider has documented MDD — always check if MDD criteria are mentioned

Defaulting to F32.A for any mention of 'depression' without reviewing the clinical context

Not querying the provider to clarify whether this represents MDD, adjustment disorder, or another depressive condition

Confusing this with F32.9, which specifically indicates MDD single episode

Common Mistakes

HCC Buddy guidance

F32.9 — Major depressive disorder, single episode, unspecified: Use when MDD is confirmed even if severity is not specified

F32.89 — Other specified depressive episodes: Provider describes the condition but it does not meet other criteria

F33.9 — Major depressive disorder, recurrent, unspecified: Use when recurrent MDD is documented

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.A

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

What This Code Means

F32.A is the ICD-10-CM diagnosis code for depression, unspecified. This code represents depression that has been diagnosed but the specific type or severity level has not been documented or specified by the healthcare provider. It is used when a patient has depressive symptoms but the clinical details needed to assign a more specific depression code are not available. F32.A sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mood [affective] disorders (f30-f39).

F32.A is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This code does not map to a CMS-HCC V28 payment category. Capture depends on documentation that supports the diagnosis; verify the HCC assignment against the current CMS mapping for the applicable payment year. Coders reviewing F32.A should check whether additional documentation would support a more specific child code in the same hierarchy that does map to a payment HCC, capturing the correct specificity is the highest-impact RAF improvement available within accurate coding.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for F32.A sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Query the provider if more specific information is available, such as severity level (mild, moderate, severe) or episode type (single vs. recurrent), as more specific F32 codes may be more appropriate
•Do not use this code if the depression is clearly documented as mild (F32.0), moderate (F32.1), or severe (F32.2, F32.3), or if it is a recurrent depressive disorder (F33 codes)

Clinical Significance

Depression, unspecified is the least specific depression code, used when the provider documents depression without confirming major depressive disorder criteria or specifying the type and severity. This code was introduced to distinguish unqualified mentions of 'depression' from confirmed MDD. It represents a significant documentation improvement opportunity, as more specific coding would better capture the patient's condition.

✓Provider documentation of depression as a diagnosis or clinical concern
✓If possible, query provider to determine: Does this meet MDD criteria? Is this a single or recurrent episode? What is the severity?
