Audit Caution

HCC Buddy guidance

Confusing stimulant withdrawal symptoms (fatigue, depression) with a primary depressive episode

Coding intoxication when the patient is actually in withdrawal — the presentations can overlap in early stages

Not documenting withdrawal when the patient presents with classic post-stimulant crash symptoms

Failing to assess and document suicide risk, which is elevated during stimulant withdrawal

Common Mistakes

HCC Buddy guidance

F15.220 — Stimulant dependence with intoxication; opposite presentation — withdrawal vs. intoxication

F15.20 — Stimulant dependence, uncomplicated; use when no withdrawal or other complications are present

F15.93 — Stimulant use, unspecified with withdrawal; less specific regarding dependence status

F14.23 — Cocaine dependence with withdrawal; use when cocaine is specifically identified

Is F15.23 an HCC code?

Yes. F15.23 (Other stimulant dependence with withdrawal) 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: F15.23 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 F15.23

For F15.23, 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

F15.23 is the ICD-10-CM diagnosis code for other stimulant dependence with withdrawal. A person dependent on stimulants who is experiencing withdrawal symptoms, such as fatigue, depression, or anxiety, after stopping or reducing stimulant use. F15.23 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, F15.23 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 withdrawal symptoms such as dysphoria, fatigue, sleep disturbance, or anhedonia. For F15.23, 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 F15.23 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Document withdrawal symptoms such as dysphoria, fatigue, sleep disturbance, or anhedonia
•Withdrawal from stimulants typically presents differently than withdrawal from depressants

Clinical Significance

Stimulant dependence with withdrawal captures the acute physiological and psychological response to cessation or reduction of stimulant use in a dependent patient. Stimulant withdrawal, while generally not life-threatening like alcohol or benzodiazepine withdrawal, is characterized by profound dysphoria, fatigue, psychomotor retardation, and increased suicide risk. This diagnosis is clinically significant for both treatment planning and risk adjustment.

Documentation Requirements

✓Documented stimulant dependence
✓Documentation of withdrawal symptoms: dysphoria, fatigue, vivid dreams, insomnia or hypersomnia, increased appetite, psychomotor agitation or retardation
✓Temporal relationship to cessation or reduction of stimulant use
✓Assessment of suicide risk during withdrawal period
✓Treatment plan for withdrawal management and ongoing dependence
