What is the ICD-10 code for unspecified contact dermatitis due to drugs in contact with skin?
The ICD-10-CM code for unspecified contact dermatitis due to drugs in contact with skin is L25.1 (sometimes written as L251). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is L25.1 (Unspecified contact dermatitis) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report unspecified contact dermatitis due to drugs in contact with skin on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does L25.1 group to?
When unspecified contact dermatitis due to drugs in contact with skin is the principal diagnosis on an inpatient stay, it groups to MS-DRG 607, 606, with relative weights from 0.8772 to 1.5721 depending on complications. Higher weights mean higher Medicare reimbursement.

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).
