About L72.1

L72.1 is the ICD-10-CM diagnosis code for Pilar and trichodermal cyst. It belongs to category L72 (follicular cysts of skin and subcutaneous tissue), block L60-L75 (disorders of skin appendages) and chapter 12 (diseases of the skin and subcutaneous tissue). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within L72 (follicular cysts of skin and subcutaneous tissue), L72.1 is specifically for Pilar and trichodermal cyst. Related codes cover epidermal cyst (L72.0), 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).

To report this condition, pick the subcode that matches the documentation: L72.11 (cyst) and L72.12 (cyst).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
