Buddy Documentation Tip

Documentation of stimulant use

Evidence of current intoxication

Specific perceptual disturbances described (visual, auditory, tactile hallucinations or illusions)

Audit Caution

HCC Buddy guidance

Coding uncomplicated intoxication when perceptual disturbances are documented

Confusing transient intoxication-related perceptual changes with a persistent psychotic disorder

Not documenting the specific types of perceptual disturbances for clinical accuracy

Using the unspecified intoxication code (F15.929) when perceptual disturbances are present

Common Mistakes

HCC Buddy guidance

F15.920 — Stimulant use, unspecified with uncomplicated intoxication; no perceptual disturbances

F15.921 — Stimulant use, unspecified with intoxication delirium; delirium involves broader cognitive impairment

F15.950 — Stimulant use, unspecified with psychotic disorder with delusions; persistent psychosis, not transient intoxication

F15.222 — Stimulant dependence with intoxication with perceptual disturbance; use when dependence is documented

Is F15.922 an HCC code?

Yes. F15.922 (Other stimulant use, unspecified with intoxication with perceptual disturbance) 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: F15.922 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 F15.922

For F15.922, 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

F15.922 is the ICD-10-CM diagnosis code for other stimulant use, unspecified with intoxication with perceptual disturbance. A person using stimulant drugs who is currently intoxicated and experiencing perceptual disturbances such as hallucinations or illusions caused by the drug. F15.922 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, F15.922 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. 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 the type of perceptual disturbance (visual, auditory, tactile hallucinations) for clinical clarity. For F15.922, 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 F15.922 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Document the type of perceptual disturbance (visual, auditory, tactile hallucinations) for clinical clarity
•Differentiate between stimulant-induced perceptual disturbances and primary psychotic disorders

Clinical Significance

Stimulant use, unspecified with intoxication with perceptual disturbance captures patients experiencing sensory alterations during stimulant intoxication when the use pattern is not specified. Perceptual disturbances are a common complication of stimulant intoxication and may include visual, auditory, or tactile hallucinations. This code is important for documenting the severity of the intoxication episode.

Documentation Requirements

✓Documentation of stimulant use
✓Evidence of current intoxication
✓Specific perceptual disturbances described (visual, auditory, tactile hallucinations or illusions)
✓Documentation that disturbances are occurring during acute intoxication
✓Clinical assessment of severity and safety interventions

Commonly Confused Codes

•F15.920: Stimulant use, unspecified with uncomplicated intoxication; no perceptual disturbances
•F15.921: Stimulant use, unspecified with intoxication delirium; delirium involves broader cognitive impairment
•F15.950: Stimulant use, unspecified with psychotic disorder with delusions; persistent psychosis, not transient intoxication
•F15.222: Stimulant dependence with intoxication with perceptual disturbance; use when dependence is documented
