A pilonidal sinus is a small hole or tunnel in the skin at the top of the buttocks, where they divide (the cleft). It does not always cause symptoms and only needs to be treated if it becomes infected.
A pilonidal cyst (also called pilonidal cyst disease, intergluteal pilonidal disease or pilonidal sinus) is a skin condition that happens in the crease of the buttocks — anywhere from the tailbone to the anus. A pilonidal cyst can be extremely painful especially when sitting.

According to the AMA CPT Manual, Integumentary section, codes 10080-10081 (Incision and drainage of pilonidal cyst) or 11770-11772 (Excision of pilonidal cyst or sinus) must include an ICD-10 diagnosis code of Pilonidal Cyst or Pilonidal Sinus.
Additional sinuses are frequent. Cyst cavities are lined with chronic granulation tissue and may contain hair, epithelial debris, and young granulation tissue. Cutaneous appendages are not seen in the wall of cysts, meaning the cysts lack epithelial lining, unlike the sinus.
The pilonidal sinus may terminate at a cavity that is wider than the rest of the tract and can be filled with debris or hair. This is the part of the pilonidal structure that is usually described as the cyst, even though it doesn't officially meet the qualifications to be a cyst.
