About coding Milium
The ICD-10-CM code for Milium is L72.0 (Epidermal cyst). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on L72.0.
Within L72 (follicular cysts of skin and subcutaneous tissue), L72.0 is specifically for epidermal cyst. Related codes cover Pilar and trichodermal cyst (L72.1), Steatocystoma multiplex (L72.2), sebaceous cyst (L72.3), other follicular cysts of the skin and subcutaneous tissue (L72.8) and follicular cyst of the skin and subcutaneous tissue, unspecified (L72.9).
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.
