What is ICD-10 code F13.180?

F13.180 is the ICD-10-CM diagnosis code for Sedative, hypnotic or anxiolytic abuse with sedative, hypnotic or anxiolytic-induced anxiety disorder. Misuse of sedatives, sleeping pills, or anti-anxiety medications that causes or worsens anxiety symptoms. It belongs to the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99). F13.180 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F13.180 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. F13.180 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. F13.180 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 F13.180 map to under V28?

F13.180 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.

Failing to distinguish between withdrawal anxiety and substance-induced anxiety disorder — these are different clinical entities

Assigning dependence codes when documentation only supports abuse

Not capturing the induced disorder and defaulting to uncomplicated abuse F13.10

Common Mistakes

HCC Buddy guidance

F13.280 — Sedative DEPENDENCE with induced anxiety disorder; requires dependence rather than abuse

F13.980 — Unspecified sedative use with induced anxiety; use when abuse vs dependence is unclear

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

F13.10 — Uncomplicated sedative abuse; does not capture the anxiety complication

Is F13.180 an HCC code?

Yes. F13.180 (Sedative, hypnotic or anxiolytic abuse 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: F13.180 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.

Not separately weighted

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 review for F13.180

For F13.180, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.

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

What This Code Means

F13.180 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic abuse with sedative, hypnotic or anxiolytic-induced anxiety disorder. Misuse of sedatives, sleeping pills, or anti-anxiety medications that causes or worsens anxiety symptoms. F13.180 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, F13.180 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 F13.180; use the applicable model and payment year when reviewing the V28 mapping. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. 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.

Document whether anxiety is a new symptom or worsening of pre-existing anxiety. For F13.180, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule. 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 F13.180 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Document whether anxiety is a new symptom or worsening of pre-existing anxiety
•This code indicates substance-induced anxiety, distinguishing it from primary anxiety disorders

Clinical Significance

Sedative-induced anxiety disorder in the context of abuse represents a paradoxical complication where anti-anxiety medications actually cause or worsen anxiety. This is clinically significant because it indicates the substance use is producing the very symptom it is often prescribed to treat. The induced disorder adds complexity to treatment planning and reflects a pattern of problematic substance use requiring intervention.

Documentation Requirements

✓Specific sedative, hypnotic, or anxiolytic substance identified
✓Documentation that anxiety is substance-induced rather than a pre-existing anxiety disorder
✓Temporal relationship between substance use and anxiety symptom onset
✓Pattern of use meeting criteria for abuse (not dependence)
✓Description of anxiety symptoms (panic attacks, generalized anxiety, phobic features)
✓Assessment distinguishing between rebound anxiety and substance-induced anxiety disorder

Commonly Confused Codes
