What is ICD-10 code F12.929?

F12.929 is the ICD-10-CM diagnosis code for Cannabis use, unspecified with intoxication, unspecified. A person who uses cannabis without dependence and experiences intoxication, but the specific characteristics of the intoxication are not documented. It belongs to the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99). F12.929 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. F12.929 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. F12.929 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. F12.929 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 F12.929 map to under V28?

F12.929 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for F12.929?

F12.929 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for F12.929?

F12.929 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports F12.929?

This is a less specific code; clarify whether intoxication is complicated by perceptual disturbances before using this code Use only when documentation does not provide sufficient detail to assign F12.920 or F12.922 F12.929 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

F12.920 — Cannabis use, unspecified with intoxication, uncomplicated; use when documentation confirms uncomplicated intoxication

F12.921 — Cannabis use, unspecified with intoxication delirium; use when delirium is present

F12.922 — Cannabis use, unspecified with intoxication with perceptual disturbance; use when perceptual changes occur

Is F12.929 an HCC code?

F12.929 is not in the CMS-HCC V28 or V24 community payment model. F12.929 has a separate mapping under the CMS-HCC ESRD model (HCC 55 (Substance Use Disorder/Moderate/Severe/Substance Use with Complications)); the applicable result needs member context. F12.929 also appears in the HHS-HCC commercial risk model (HCC 082 (HHS-HCC 082 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping.

HCC Category Mapping

ESRDHCC 55, Substance Use Disorder/Moderate/Severe/Substance Use with Complications

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 Criteria for F12.929

For F12.929 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 F12.929 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

F12.929 is the ICD-10-CM diagnosis code for cannabis use, unspecified with intoxication, unspecified. A person who uses cannabis without dependence and experiences intoxication, but the specific characteristics of the intoxication are not documented. F12.929 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).

F12.929 has no mapping under the CMS-HCC V28 or V24 community payment models. F12.929 has a separate mapping under the CMS-HCC ESRD model (HCC 55 (Substance Use Disorder/Moderate/Severe/Substance Use with Complications)); the applicable result needs member context. F12.929 also appears in the HHS-HCC commercial risk model (HCC 082 (HHS-HCC 082 adult, RAF varies by metal level)), which is a commercial market model rather than a Medicare Advantage payment mapping. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

This is a less specific code; clarify whether intoxication is complicated by perceptual disturbances before using this code.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for F12.929 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•This is a less specific code; clarify whether intoxication is complicated by perceptual disturbances before using this code
•Use only when documentation does not provide sufficient detail to assign F12.920 or F12.922

Clinical Significance

Cannabis use, unspecified with unspecified intoxication is the least specific code for cannabis intoxication, used when neither the severity of the use disorder nor the specific features of intoxication are documented. This code represents a dual documentation gap and should prompt coders to query providers for both the severity of cannabis use and the nature of intoxication symptoms.

Documentation Requirements

✓Documentation of cannabis use
✓Evidence of intoxication at the encounter
✓Basic clinical findings supporting intoxication
✓Documentation of why more specific information is unavailable
