F15.280
BillableOther stimulant dependence with stimulant-induced anxiety disorder
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F15.280 an HCC code?
Yes. F15.280 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 F15.280
For F15.280 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 F15.280 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F15.280 is the ICD-10-CM diagnosis code for other stimulant dependence with stimulant-induced anxiety disorder. A person is dependent on stimulant drugs (like cocaine, amphetamines, or similar substances) and experiences anxiety disorder as a direct result of their stimulant use. The anxiety symptoms are caused by and connected to the stimulant substance abuse. F15.280 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, F15.280 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, F15.280 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.
This code requires documentation of both the stimulant dependence AND the anxiety disorder being stimulant-induced; do not use this code if anxiety exists independently of the substance use. Because F15.280 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 F15.280 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code requires documentation of both the stimulant dependence AND the anxiety disorder being stimulant-induced; do not use this code if anxiety exists independently of the substance use
- •The '280' specifies 'with stimulant-induced anxiety disorder' - verify the clinical record clearly links the anxiety symptoms to stimulant use rather than coding anxiety as a separate comorbidity
Clinical Significance
Stimulant dependence with stimulant-induced anxiety disorder reflects a common complication where chronic stimulant use triggers or exacerbates anxiety through persistent sympathomimetic activation. Patients with stimulant dependence frequently develop anxiety that persists beyond acute intoxication, complicating treatment and recovery. Capturing this dual diagnosis supports accurate severity representation and resource allocation.
Documentation Requirements
- ✓Documented stimulant dependence
- ✓Clinical description of anxiety disorder symptoms (panic, generalized anxiety, phobic features)
- ✓Documentation that anxiety is induced by stimulant use, not a pre-existing condition
- ✓Temporal relationship between stimulant use pattern and anxiety onset or exacerbation
- ✓Treatment addressing both the anxiety disorder and the underlying dependence
Commonly Confused Codes
- •F15.180 — Stimulant abuse with anxiety disorder; requires abuse rather than dependence
- •F15.980 — Stimulant use, unspecified with anxiety disorder; less specific regarding use pattern
- •F41.1 — Generalized anxiety disorder; primary anxiety, not substance-induced
- •F41.0 — Panic disorder; primary panic, not substance-induced
- •F14.280 — Cocaine dependence with anxiety disorder; use when cocaine is identified
