Questions About F19.982Overview

Is F19.982 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other psychoactive substance use, unspecified with psychoactive substance-induced sleep disorder on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does F19.982 group to?

When other psychoactive substance use, unspecified with psychoactive substance-induced sleep 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 F19.982 be reported with a code from F19.1?

Not as a rule. The Excludes1 note at F19.9, which applies to F19.982, lists "other psychoactive substance abuse (F19.1-)". 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 F19.982?

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 F19.982 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, F19.982 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).
