What 20704 covers
An orthopedic surgeon reports 20704 when manually preparing a drug-delivery device and placing it inside a joint during operative treatment. A common situation is staged management of an infected joint, with antibiotic mixed into cement and formed as an intra-articular spacer or beads. The work is performed in the operating room as part of the joint procedure; this code identifies device preparation and placement, not the underlying debridement, revision, or other primary operation.
Report 20704 only with a primary procedure; it is an add-on and is not submitted by itself. The operative note should identify the joint, describe manual preparation of the drug-delivery device and its intra-articular placement, and support the associated primary procedure. CMS places payment for this add-on within the primary procedure's global period. Select this code by the device's final location: placement in the joint, rather than deep soft tissue or the intramedullary canal, distinguishes it from neighboring insertion codes.
