About coding Cock's peculiar tumor
The ICD-10-CM code for Cock's peculiar tumor is L72.3 (Sebaceous cyst).
Within L72 (follicular cysts of skin and subcutaneous tissue), L72.3 is specifically for sebaceous cyst. Related codes cover epidermal cyst (L72.0), Pilar and trichodermal cyst (L72.1), Steatocystoma multiplex (L72.2), other follicular cysts of the skin and subcutaneous tissue (L72.8) and follicular cyst of the skin and subcutaneous tissue, unspecified (L72.9).
The conditions in its Excludes2 note aren't part of L72.3, but may be coded alongside it if the patient has both: pilar cyst (L72.11) and trichilemmal (proliferating) cyst (L72.12).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
