CPT® Code 20615

The procedure described by CPT® Code 20615 involves the aspiration and injection for the treatment of a bone cyst. In this context, a bone cyst is defined as a one-chambered sac that contains serous fluid, which is a clear, pale yellow fluid that can accumulate in various tissues. The cyst is typically lined with a thin layer of connective tissue. This procedure is commonly performed in pediatric patients, as bone cysts are frequently found in the shaft of long bones in children. The physician begins the process by administering local anesthesia to ensure the patient experiences minimal discomfort during the procedure. Following anesthesia, a needle is carefully inserted into the bone cyst to aspirate, or withdraw, the fluid contained within it. After the fluid is removed, medication is injected into the cyst to treat the condition. This dual approach of aspiration and injection aims to alleviate symptoms and promote healing of the bone cyst.
