What 20985 covers

This add-on describes a surgeon’s use of computer navigation during a musculoskeletal operation without a preloaded CT or MRI image set. The system registers the patient’s anatomy during surgery and tracks instruments to help guide their position or alignment. Orthopedic surgeons commonly use this approach during joint replacement, including total knee arthroplasty, in hospital operating rooms and ambulatory surgical settings.

Report 20985 with the primary operation for which the navigation was used, not by itself. The operative record should identify the musculoskeletal procedure and support that image-less computer navigation was performed, such as intraoperative anatomy registration and instrument tracking. Medicare treats 20985 as an add-on: it is billed with a primary procedure and paid within that procedure’s global period. The navigation service supplements the operative work; the primary code still identifies the surgery performed.
