Other stimulant abuse with other stimulant-induced disorder

This code describes a situation where someone is abusing stimulant drugs (like cocaine, amphetamines, or similar substances) and has developed other related health problems as a result of that abuse. The 'other' designation means the specific disorder caused by the stimulant use doesn't fit into more common categories like anxiety or sleep problems.

Documented stimulant abuse pattern
Specific description of the induced disorder that does not fit other F15.18x categories
Clear causal link between stimulant use and the disorder
Documentation that the disorder is not a pre-existing condition or primary diagnosis

Audit Caution

HCC Buddy guidance
Using this catch-all code when a more specific F15.18x code applies
Failing to document the specific disorder induced by stimulant use, making the code difficult to audit
Confusing with F15.19 (unspecified) — F15.188 indicates a known but 'other' disorder, while F15.19 means the disorder is unknown
Not recognizing less common stimulant-induced conditions like movement disorders or OCD-like symptoms

Common Mistakes

HCC Buddy guidance
F15.180 — Stimulant abuse with anxiety disorder; use when anxiety is the specific induced condition
F15.181 — Stimulant abuse with sexual dysfunction; use when sexual dysfunction is specified
F15.182 — Stimulant abuse with sleep disorder; use when sleep disorder is specified
F15.19 — Stimulant abuse with unspecified induced disorder; use only when the disorder cannot be identified at all

Is F15.188 an HCC code?

Yes. F15.188 (Other stimulant abuse with other stimulant-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: F15.188 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.

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 F15.188

For F15.188, 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

F15.188 is the ICD-10-CM diagnosis code for other stimulant abuse with other stimulant-induced disorder. This code describes a situation where someone is abusing stimulant drugs (like cocaine, amphetamines, or similar substances) and has developed other related health problems as a result of that abuse. The 'other' designation means the specific disorder caused by the stimulant use doesn't fit into more common categories like anxiety or sleep problems. F15.188 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, F15.188 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 F15.188; 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.

Verify documentation specifies both the abuse of stimulants AND an additional stimulant-induced disorder; if only abuse is documented without a specific induced condition, use F15.18 instead. For F15.188, 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 F15.188 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • •Verify documentation specifies both the abuse of stimulants AND an additional stimulant-induced disorder; if only abuse is documented without a specific induced condition, use F15.18 instead
  • •Review the medical record to identify what specific disorder was induced (such as psychosis, mood disorder, or sexual dysfunction) as this may require an additional code for the induced condition itself

Clinical Significance

This code captures other stimulant-induced disorders during abuse that do not fit into the specific categories of psychosis, anxiety, sexual dysfunction, or sleep disorder. Examples include stimulant-induced obsessive-compulsive disorder, movement disorders, or neurocognitive changes. Documenting these less common but clinically significant complications ensures complete representation of the patient's condition burden.

Documentation Requirements

  • ✓Documented stimulant abuse pattern
  • ✓Specific description of the induced disorder that does not fit other F15.18x categories
  • ✓Clear causal link between stimulant use and the disorder
  • ✓Documentation that the disorder is not a pre-existing condition or primary diagnosis
  • ✓Clinical management plan for the induced disorder

Commonly Confused Codes

  • •F15.180: Stimulant abuse with anxiety disorder; use when anxiety is the specific induced condition
  • •F15.181: Stimulant abuse with sexual dysfunction; use when sexual dysfunction is specified
  • •F15.182: Stimulant abuse with sleep disorder; use when sleep disorder is specified
  • •F15.19: Stimulant abuse with unspecified induced disorder; use only when the disorder cannot be identified at all
  • •F15.288: Stimulant dependence with other induced disorder; requires documented dependence
