F12.988

Billable

Cannabis use, unspecified with other cannabis-induced disorder

Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)

Is F12.988 an HCC code?

Yes. F12.988 maps to Drug Use Disorder/Substance Use Disorder, Moderate/Severe under the CMS-HCC V28 risk adjustment model (and Drug/Alcohol Dependence under V24).

RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for F12.988

For F12.988 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 F12.988 during that encounter — not just copy-forwarded from a problem list.

What This Code Means

F12.988 is the ICD-10-CM diagnosis code for cannabis use, unspecified with other cannabis-induced disorder. A person uses cannabis in an unspecified pattern and has developed another cannabis-related health problem, such as cannabis hyperemesis syndrome or other specified disorder. F12.988 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, F12.988 maps to Drug Use Disorder/Substance Use Disorder, Moderate/Severe (HCC 137) with a community, non-dual, aged base RAF weight of 0.358. Under the older CMS-HCC V24 model, F12.988 maps to Drug/Alcohol Dependence (HCC 55) with a community, non-dual, aged base RAF weight of 0.334. 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.

Use this code when documentation specifies a particular cannabis-induced disorder not captured by other F12 codes. Because F12.988 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. 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, RAF weights, and MEAT documentation criteria for F12.988 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Use this code when documentation specifies a particular cannabis-induced disorder not captured by other F12 codes
  • Review clinical notes for the specific disorder induced by cannabis use to ensure accurate coding

Clinical Significance

Cannabis use, unspecified with other cannabis-induced disorder captures specific cannabis-related complications not classified elsewhere, such as cannabis hyperemesis syndrome, when the severity of the use disorder is not documented. Cannabis hyperemesis syndrome has become increasingly recognized as cannabis potency has increased and is characterized by cyclic vomiting, nausea, and compulsive hot water bathing. Documenting these conditions ensures comprehensive clinical care and appropriate risk adjustment.

Documentation Requirements

  • Documentation of cannabis use
  • Description of the specific cannabis-induced disorder (name and characterize)
  • Causal link between cannabis use and the disorder
  • Clinical evidence supporting the diagnosis
  • Exclusion of other potential causes for the disorder
  • Confirmation that the disorder does not fit anxiety, psychosis, or sleep disorder categories
