F19.239
BillableOther psychoactive substance dependence with withdrawal, unspecified
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is F19.239 an HCC code?
Yes. F19.239 maps to Drug Use Disorder/Substance Use Disorder, Moderate/Severe under the CMS-HCC V28 risk adjustment model (and Drug/Alcohol Dependence under V24).
HCC Category Mapping
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 F19.239
For F19.239to 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 F19.239 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
F19.239 is the ICD-10-CM diagnosis code for other psychoactive substance dependence with withdrawal, unspecified. Addiction to various drugs or substances with withdrawal symptoms, but the specific type of withdrawal is not specified. F19.239 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, F19.239 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, F19.239 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 only when withdrawal is present but the specific manifestations are not documented. Because F19.239 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 F19.239 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 present but the specific manifestations are not documented
- •Query the provider if withdrawal symptoms are documented but not clearly specified to allow for more specific coding
Clinical Significance
This code captures other psychoactive substance withdrawal syndrome where the specific complications are not documented. Withdrawal indicates physiological dependence and requires medical management to prevent potentially life-threatening complications. While less specific, this code still captures a clinically significant state that elevates resource needs.
Documentation Requirements
- ✓Provider documentation specifying the psychoactive substance(s) involved (e.g., designer drugs, bath salts, kratom, polysubstance use)
- ✓Clinical documentation supporting dependence criteria: tolerance, withdrawal symptoms, compulsive use despite harm, or inability to control use
- ✓Documentation of withdrawal symptoms temporally related to cessation or reduction of substance use
- ✓Assessment and plan addressing the substance use disorder with treatment approach documented
Commonly Confused Codes
- •F19.10-F19.19 (Other psychoactive substance abuse) — abuse indicates a less severe use pattern without meeting dependence criteria
- •F19.90-F19.99 (Other psychoactive substance use, unspecified) — unspecified use is used when the severity of the use disorder is not documented
- •F19.230 (Withdrawal, uncomplicated) — use when documentation confirms no delirium or perceptual disturbances during withdrawal
- •F10-F16 (Specific substance codes: alcohol, opioids, cannabis, sedatives, cocaine, stimulants) — use substance-specific codes when the substance is identified; F19 is for 'other' or multiple unspecified substances
