Is F12.180 an HCC code?
Yes. F12.180 (Cannabis abuse with cannabis-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: F12.180 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.

HCC Category Mapping
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 F12.180
For F12.180, 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
F12.180 is the ICD-10-CM diagnosis code for cannabis abuse with cannabis-induced anxiety disorder. A person is abusing cannabis and has developed an anxiety disorder that is directly caused by their cannabis use. F12.180 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, F12.180 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 F12.180; 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.
The anxiety must be documented as induced by cannabis, not as a primary anxiety disorder. For F12.180, 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 F12.180 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •The anxiety must be documented as induced by cannabis, not as a primary anxiety disorder
- •Ensure the anxiety symptoms are temporally related to cannabis use and not better explained by another condition
Clinical Significance
Cannabis abuse with cannabis-induced anxiety disorder captures a common psychiatric complication where cannabis use directly causes clinically significant anxiety. Cannabis-induced anxiety is one of the most frequently reported adverse effects and may present as generalized anxiety, panic attacks, or social anxiety symptoms. This diagnosis is important because it indicates that cannabis use is causing measurable psychiatric morbidity beyond the substance use disorder itself.
Documentation Requirements
- ✓Documentation of cannabis abuse (maladaptive use pattern)
- ✓Specific anxiety symptoms documented (generalized anxiety, panic attacks, social anxiety, etc.)
- ✓Clinical statement that anxiety is induced by cannabis use, not a pre-existing independent condition
- ✓Temporal relationship between cannabis use and anxiety symptoms
- ✓Exclusion of primary anxiety disorders unrelated to substance use
Commonly Confused Codes
- •F41.1: Generalized anxiety disorder; use for primary anxiety not related to substance use
- •F41.0: Panic disorder; use for primary panic disorder not substance-induced
- •F12.280: Cannabis dependence with cannabis-induced anxiety disorder; use when dependence is documented
- •F12.980: Cannabis use, unspecified with anxiety disorder; use when severity of use disorder is unspecified
