CPT® Code 27604

The procedure described by CPT® Code 27604 refers to the surgical intervention known as incision and drainage of an infected bursa located in the leg or ankle. An infected bursa is a fluid-filled sac that becomes inflamed and can lead to pain and swelling in the affected area. The procedure involves making a precise incision in the skin directly over the infected bursa to allow for drainage of the accumulated fluid and pus. This is a critical step in managing infections, as it helps to alleviate pressure, reduce pain, and promote healing. The drainage process typically includes flushing the cavity with saline or an antibiotic solution to ensure that any remaining infectious material is cleared out. Depending on the extent of the infection and the surgeon's assessment, drains may be placed to facilitate ongoing drainage and prevent fluid accumulation. The incision may be closed in layers to promote proper healing or packed with gauze and left open to allow for continued drainage. This procedure is essential for treating infections effectively and preventing further complications.
