About coding seasonal bullous dermatitis
The ICD-10-CM code for seasonal bullous dermatitis is L30.8 (Other specified dermatitis).
Within L30, choose L30.8 (Other specified dermatitis) only when documentation doesn't support a more specific option: Nummular dermatitis (L30.0), Dyshidrosis [pompholyx] (L30.1), cutaneous autosensitization (L30.2), infective dermatitis (L30.3), erythema intertrigo (L30.4), pityriasis alba (L30.5) 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.
