About coding Pilar cyst
The ICD-10-CM code for Pilar cyst is L72.11 (Pilar cyst).
Within L72.1 (Pilar and trichodermal cyst), L72.11 is specifically for Pilar cyst. Related codes cover trichodermal cyst (L72.12).
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.
