About coding Papillaris capillitii dermatitis
The ICD-10-CM code for Papillaris capillitii dermatitis is L73.0 (Acne keloid).
Within L73 (other follicular disorders), L73.0 is specifically for acne keloid. Related codes cover Pseudofolliculitis barbae (L73.1), Hidradenitis suppurativa (L73.2), other specified follicular disorders (L73.8) and follicular disorder, unspecified (L73.9).
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.
