About L24.A9

L24.A9 is the ICD-10-CM diagnosis code for irritant contact dermatitis due friction or contact with other specified body fluids. It belongs to category L24 (irritant 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 L24.A, choose L24.A9 (friction or contact with other specified body fluids) only when documentation doesn't support a more specific option: unspecified (L24.A0), to saliva (L24.A1) and to fecal, urinary or dual incontinence (L24.A2).

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 was added in FY2022, effective October 1, 2021.
