What is ICD-10 code F13.280?

F13.280 is the ICD-10-CM diagnosis code for Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced anxiety disorder. A person is dependent on sedatives, sleeping pills, or anti-anxiety medications and is experiencing anxiety symptoms caused by these drugs. F13.280 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F13.280 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. F13.280 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. F13.280 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 F13.280 map to under V28?

F13.280 maps to CMS-HCC V28 HCC 137 (Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications). The category numbers, labels, and conditions come from the CMS-HCC V28 model file for payment year 2026.

Common Mistakes

F13.180 — Sedative ABUSE with induced anxiety disorder; less severe use pattern

F13.980 — Unspecified sedative use with induced anxiety; use when dependence is not confirmed

F41.1 — Generalized anxiety disorder; primary anxiety, not substance-induced

Is F13.280 an HCC code?

Yes. F13.280 (Sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced anxiety disorder) maps to HCC 137, Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.424. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.

Coder answer: F13.280 is billable and maps to V28 HCC 137, Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. 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 context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT Criteria for F13.280

For F13.280 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 F13.280 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

F13.280 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic dependence with sedative, hypnotic or anxiolytic-induced anxiety disorder. A person is dependent on sedatives, sleeping pills, or anti-anxiety medications and is experiencing anxiety symptoms caused by these drugs. F13.280 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, F13.280 maps to Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications (HCC 137) with a source-labeled community, non-dual, aged reference coefficient of 0.424. No V24 mapping is shown for F13.280; use the applicable model and payment year when reviewing the V28 mapping. 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. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.

This paradoxical effect (anxiety from anti-anxiety medications) should be clearly documented by the provider. Because F13.280 maps to an HCC category, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. 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, source-labeled coefficient references, and MEAT documentation criteria for F13.280 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•This paradoxical effect (anxiety from anti-anxiety medications) should be clearly documented by the provider
•Differentiate between anxiety as a withdrawal symptom versus anxiety induced during active use

Clinical Significance

Sedative dependence with induced anxiety disorder is a paradoxical but well-recognized complication where chronic anxiolytic dependence actually causes or worsens anxiety. This is common with benzodiazepine dependence, where neuroadaptation leads to increased baseline anxiety. The dual nature of this condition — depending on a substance that worsens the target symptom — creates treatment challenges and reflects significant clinical complexity.

Documentation Requirements

✓Documentation of sedative, hypnotic, or anxiolytic dependence
✓Description of anxiety symptoms and their relationship to the substance use
✓Clinical distinction from pre-existing primary anxiety disorder
✓Differentiation from withdrawal-related anxiety versus substance-induced anxiety disorder
✓Assessment of anxiety severity (GAD-7 or similar scale if available)
✓Treatment plan addressing both the dependence and the induced anxiety

Commonly Confused Codes

•F13.180: Sedative ABUSE with induced anxiety disorder; less severe use pattern
•F13.980: Unspecified sedative use with induced anxiety; use when dependence is not confirmed
•F41.1: Generalized anxiety disorder; primary anxiety, not substance-induced
•F13.230: Dependence with withdrawal uncomplicated; withdrawal anxiety is a different clinical entity
