About coding transient acantholytic dermatosis
The ICD-10-CM code for transient acantholytic dermatosis is L11.1 (Transient acantholytic dermatosis [Grover]).
Within L11 (other acantholytic disorders), L11.1 is specifically for transient acantholytic dermatosis [Grover]. Related codes cover acquired keratosis follicularis (L11.0), other specified acantholytic disorders (L11.8) and acantholytic disorder, unspecified (L11.9).
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.
