What is the appropriate code for a breast biopsy resulting in the excision of a benign lump?

The appropriate code for a breast biopsy that results in the excision of a benign lump is 19120-LT. This code specifically relates to a percutaneous excisional biopsy of the breast, which is performed when a palpable lesion is removed for both diagnosis and often treatment of a benign condition.

The "LT" designation indicates the procedure was performed on the left side, which is important for accurately documenting the site of the procedure. This code encompasses all the actions involved in excising the lump from the breast, reflecting the surgical nature of the procedure itself.

In contrast, the other codes provided represent different types of procedures or anatomical sites. For instance, 57522 pertains to a procedure on the cervix rather than the breast, while 14040 refers to a surgical excision involving a different site altogether, specifically for skin lesions. Finally, 11420 is for excising benign skin lesions, which does not apply to breast biopsy procedures. Thus, 19120-LT is the most accurate code for the stated procedure involving the excision of a benign breast lump.
