About L72.3

L72.3 is the ICD-10-CM diagnosis code for sebaceous 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

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.

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

Before ICD-10, this condition was coded in ICD-9-CM as 706.2 (sebaceous cyst).
