About coding Wilkinson-Sneddon disease or syndrome
The ICD-10-CM code for Wilkinson-Sneddon disease or syndrome is L13.1 (Subcorneal pustular dermatitis).
Within L13 (other bullous disorders), L13.1 is specifically for Subcorneal pustular dermatitis. Related codes cover dermatitis herpetiformis (L13.0), other specified bullous disorders (L13.8) and bullous disorder, unspecified (L13.9).
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.
