Is F12.29 an HCC code?
Yes. F12.29 (Cannabis dependence with unspecified cannabis-induced 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: F12.29 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 F12.29
For F12.29, 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
F12.29 is the ICD-10-CM diagnosis code for cannabis dependence with unspecified cannabis-induced disorder. A person dependent on cannabis who has a cannabis-induced disorder, but the specific type of disorder is not documented or specified. F12.29 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, F12.29 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 F12.29; 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.
This is a less specific code; attempt to clarify the type of cannabis-induced disorder before defaulting to this code. For F12.29, 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 F12.29 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; attempt to clarify the type of cannabis-induced disorder before defaulting to this code
- •Use only when the documentation does not provide enough detail to assign a more specific F12.28x code
Clinical Significance
Cannabis dependence with unspecified cannabis-induced disorder is the least specific code for cannabis dependence with complications. It is used when documentation confirms both dependence and an induced disorder but the specific type of induced disorder cannot be determined. This code captures risk adjustment value but represents a significant documentation improvement opportunity. Providers should always be queried to identify the specific induced disorder.
Documentation Requirements
- ✓Documentation of cannabis dependence
- ✓Statement that a cannabis-induced disorder is present
- ✓Any available clinical information about the nature of the induced disorder
- ✓Documentation of query attempts to determine the specific disorder
Commonly Confused Codes
- •F12.20: Cannabis dependence, uncomplicated; use when no induced disorder is present
- •F12.288: Cannabis dependence with other cannabis-induced disorder; use when the specific disorder IS identified
- •F12.280: Cannabis dependence with cannabis-induced anxiety disorder; use when anxiety is specified
- •F12.19: Cannabis abuse with unspecified cannabis-induced disorder; use when only abuse is documented
