CPT® Code 20700

Add-On Code

Manual preparation and insertion of drug-delivery device(s), deep (eg, subfascial) (List separately in addition to code for primary procedure)

The CPT® Code 20700 refers to the manual preparation and insertion of drug-delivery device(s) into deep tissue, specifically in subfascial locations. This procedure is performed by a physician who crafts the drug delivery devices to address the unique therapeutic needs of the patient. These devices are typically utilized in conjunction with other surgical procedures, such as debridement or arthrotomy, to enhance healing in cases of deep infections that may arise from trauma or to deliver specific treatments directly to the affected area. The process begins with the surgeon preparing the site for implantation by cleaning out any infected tissue and irrigating the area to ensure a sterile environment. Following this, the surgeon fabricates the drug delivery device using a combination of cement powder and antibiotic powder, which is mixed with a liquid monomer under vacuum conditions. This mixture is then shaped into the desired form, such as tubes or beads, which are subsequently placed into the prepared subfascial space. The insertion of these devices is critical for targeted therapy, as they can provide localized treatment and support the healing process in challenging cases. The procedure is reported separately in addition to the primary surgical procedure performed, highlighting its significance in the overall treatment plan.
