About coding Chafing
The ICD-10-CM code for Chafing is L30.4 (Erythema intertrigo).
Within L30 (other and unspecified dermatitis), L30.4 is specifically for erythema intertrigo. Related codes cover Nummular dermatitis (L30.0), Dyshidrosis [pompholyx] (L30.1), cutaneous autosensitization (L30.2), infective dermatitis (L30.3), pityriasis alba (L30.5), other specified dermatitis (L30.8) and dermatitis, unspecified (L30.9).
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.
