F13.24
BillableSedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced mood disorder
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F13.24 an HCC code?
Yes. F13.24 maps to Drug Use Disorder/Substance Use Disorder, Moderate/Severe under the CMS-HCC V28 risk adjustment model (and Drug/Alcohol Dependence under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. 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 F13.24
For F13.24 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 F13.24 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F13.24 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced mood disorder. A person dependent on sedative, hypnotic, or anti-anxiety medications has developed a mood disorder (such as depression or bipolar disorder) as a direct result of their substance use. F13.24 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering mental and behavioral disorders due to psychoactive substance use (f10-f19).
Under the CMS-HCC V28 risk adjustment model, F13.24 maps to Drug Use Disorder/Substance Use Disorder, Moderate/Severe (HCC 137) with a community, non-dual, aged base RAF weight of 0.358. Under the older CMS-HCC V24 model, F13.24 maps to Drug/Alcohol Dependence (HCC 55) with a community, non-dual, aged base RAF weight of 0.334. 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.
Document the specific mood disorder induced by the substance (depression, bipolar, etc.). Because F13.24 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 F13.24 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the specific mood disorder induced by the substance (depression, bipolar, etc.)
- •Ensure the mood disorder is documented as substance-induced rather than a primary psychiatric condition
Clinical Significance
Sedative dependence with induced mood disorder represents a significant psychiatric complication where chronic sedative dependence has caused depression, mania, or mixed mood disturbance. This dual diagnosis increases treatment complexity as both the dependence and the mood disorder require concurrent management. The substance-induced nature is key to distinguishing this from primary mood disorders.
Documentation Requirements
- ✓Documentation of sedative, hypnotic, or anxiolytic dependence
- ✓Description of the specific mood disturbance (depressive, manic, mixed)
- ✓Temporal relationship establishing mood symptoms began during or after substance use onset
- ✓Clinical distinction from primary mood disorders (major depression, bipolar disorder)
- ✓Assessment of suicidal ideation, as substance-induced mood disorders carry suicide risk
- ✓Treatment plan addressing both dependence and mood disorder concurrently
