F13.131 is a billable ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic abuse with withdrawal delirium. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 791, 793, 894 through 897. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 458 closely related codes. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Sedative-related disorders.
For Medicare Advantage risk adjustment, F13.131 maps to CMS-HCC Category 135 (Drug Use with Psychotic Complications) under the V28 model, adding a risk factor of about 0.424 for a community, non-dual, aged beneficiary in payment year 2027.

Questions About F13.131Overview
What is the ICD-10 code for sedative, hypnotic or anxiolytic abuse with withdrawal delirium?
The ICD-10-CM code for sedative, hypnotic or anxiolytic abuse with withdrawal delirium is F13.131 (sometimes written as F13131). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is F13.131 (Sedative, hypnotic or anxiolytic abuse with withdrawal) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report sedative, hypnotic or anxiolytic abuse with withdrawal delirium on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does F13.131 group to?
When sedative, hypnotic or anxiolytic abuse with withdrawal delirium is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, 894, 897, 895, 896, with relative weights from 0.6272 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Is F13.131 a CC or MCC?
CMS lists F13.131 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 458 closely related codes in its exclusion list.
Can F13.131 be reported with a code from F13.2?
Not as a rule. The Excludes1 note at F13.1, which applies to F13.131, lists "sedative, hypnotic or anxiolytic-related dependence (F13.2-)". 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 HCC is F13.131?
F13.131 (sedative, hypnotic or anxiolytic abuse with withdrawal delirium) maps to CMS-HCC Category 135 (Drug Use with Psychotic Complications), commonly written as HCC 135, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 54 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 F13.131 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, F13.131 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 1.181 depending on the payment segment). HCC 135 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 135 category page.
