Audit Caution

HCC Buddy guidance

Accepting this unspecified code without querying the provider — sedative withdrawal specificity affects patient safety decisions

Not reviewing the record for delirium or perceptual disturbance documentation that would support a more specific code

Confusing unspecified withdrawal with uncomplicated withdrawal — they are different codes with different meanings

Missing the opportunity to capture HCC 54 (Psychosis) if delirium or perceptual disturbances are actually documented

Common Mistakes

HCC Buddy guidance

F13.230 — Withdrawal uncomplicated; use when confirmed no delirium or perceptual disturbances

F13.231 — Withdrawal delirium; use when delirium criteria are met

F13.232 — Withdrawal with perceptual disturbance; use when hallucinations are present without delirium

F13.939 — Unspecified use with withdrawal unspecified; use when dependence is not confirmed

Is F13.239 an HCC code?

Yes. F13.239 (Sedative, hypnotic or anxiolytic dependence with withdrawal, unspecified) 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: F13.239 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 F13.239

For F13.239, 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

F13.239 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic dependence with withdrawal, unspecified. A person dependent on sedative, hypnotic, or anti-anxiety medications is experiencing withdrawal, but the specific type or severity of withdrawal symptoms are not documented. F13.239 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, F13.239 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.

Use this code only when withdrawal is documented but cannot be classified as uncomplicated, with delirium, or with perceptual disturbance. For F13.239, 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 F13.239 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Use this code only when withdrawal is documented but cannot be classified as uncomplicated, with delirium, or with perceptual disturbance
•Request additional documentation from the provider about withdrawal symptom details

Clinical Significance

Unspecified withdrawal from sedative dependence indicates the provider documented withdrawal but did not specify the severity or complications. Given the potentially life-threatening nature of sedative/benzodiazepine withdrawal, this documentation gap is clinically concerning. Querying the provider for specificity is important both for patient safety and accurate risk adjustment coding.

Documentation Requirements

✓Documentation of sedative, hypnotic, or anxiolytic dependence
✓Evidence of withdrawal from the substance
✓Any available clinical details about the withdrawal presentation
✓Note indicating why the specific withdrawal type could not be determined
✓Vital signs and monitoring data from the withdrawal period

Commonly Confused Codes

•F13.230: Withdrawal uncomplicated; use when confirmed no delirium or perceptual disturbances
•F13.231: Withdrawal delirium; use when delirium criteria are met
•F13.232: Withdrawal with perceptual disturbance; use when hallucinations are present without delirium
•F13.939: Unspecified use with withdrawal unspecified; use when dependence is not confirmed
•F13.20: Uncomplicated dependence; does not capture the withdrawal episode
