About L25.4
L25.4 is the ICD-10-CM diagnosis code for unspecified contact dermatitis due to food in contact with skin. It belongs to category L25 (unspecified contact dermatitis), block L20-L30 (dermatitis and eczema) and chapter 12 (diseases of the skin and subcutaneous tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within L25 (unspecified contact dermatitis), L25.4 is specifically for unspecified contact dermatitis due to food in contact with skin. Related codes cover due to cosmetics (L25.0), due to drugs in contact with skin (L25.1), due to dyes (L25.2), due to other chemical products (L25.3), due to plants, except food (L25.5), due to other agents (L25.8) and unspecified cause (L25.9).
The conditions in its Excludes2 note aren't part of L25.4, but may be coded alongside it if the patient has both: dermatitis due to ingested food (L27.2).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 692.5 (contact dermatitis and other eczema due to food in contact with skin).
