ICD-10 Code for Eczema
Also indexed as (acute) (chronic) (erythematous) (fissum) (rubrum) (squamous)
The ICD-10-CM code for eczema is L30.9 — Dermatitis, unspecified. This is the code the Alphabetic Index gives for eczema with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
L30.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
