Questions About F16.24Overview

What is the ICD-10 code for hallucinogen dependence with hallucinogen-induced mood disorder?

The ICD-10-CM code for hallucinogen dependence with hallucinogen-induced mood disorder is F16.24 (sometimes written as F1624). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is F16.24 (Hallucinogen dependence) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report hallucinogen dependence with hallucinogen-induced mood disorder on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does F16.24 group to?

When hallucinogen dependence with hallucinogen-induced mood disorder is the principal diagnosis on an inpatient stay, it groups to MS-DRG 894, 897, 895, 896, with relative weights from 0.6272 to 1.6610 depending on complications. Higher weights mean higher Medicare reimbursement.

Can F16.24 be reported with a code from F16.1?

Not as a rule. The Excludes1 note at F16.2, which applies to F16.24, lists "hallucinogen abuse (F16.1-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of F16.24?

Under the General Equivalence Mappings, hallucinogen dependence with hallucinogen-induced mood disorder converts to ICD-9-CM 292.84 (drug-induced mood disord) and 304.50 (hallucinogen dep-unspec). The mapping is approximate, so confirm the match fits the documentation.

What HCC is F16.24?

F16.24 (hallucinogen dependence with hallucinogen-induced mood disorder) maps to CMS-HCC Category 137 (Drug Use Disorder, Moderate/Severe, or Drug Use with Non-Psychotic Complications), commonly written as HCC 137, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 55 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does F16.24 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, F16.24 adds a risk adjustment factor of about 0.424 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.297 to 0.502 depending on the payment segment). A more severe related category (HCC 135 and HCC 136) supersedes it when both are reported. See the full factor table on the HCC 137 category page.
