There are no codes in the vulvar excision section for a cyst removal (other than Bartholin's) and this cyst was of the labia so that rules out the vaginal cyst excision code of 57135. The code I have settled on is 11423: Excision, benign lesion including margins...genitalia; excised diameter 2.1 to 3.0cm.
pilonidal cyst vs. abscess. I code for a billing company. The ED physician gave the dx as pilonidal abscess. He performed an I&D which included packing. If this were just any abscess, I would choose the CPT code 10061. If he had said pilonidal cyst, I would choose CPT code 10080 (I don't believe that 10081 applies since he did not mention primary closure, excision of tissue, or a Z-plasty).
