Orthopedic surgery
About 27486: Single-component knee prosthesis revision
Reports revision of an existing total knee replacement when the surgeon revises one prosthetic component, such as for loosening, wear, or instability.
An orthopedic surgeon uses this code when revising one component of an existing total knee replacement, such as a femoral or tibial component. Typical reasons include component loosening, wear, or instability. The operation may include removing the old component and placing its replacement; the code also covers use of allograft. These revisions are generally performed in an operating room, usually in a hospital or ambulatory surgery setting.
Select this code when the operative report supports revision of one component, rather than revision of both components. Document the existing prosthesis, the component revised, the reason for revision, and the work performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27486 billing questions
How do I distinguish this code from 27487?
Use this code when one prosthetic component is revised. Code 27487 describes revision of both components.
Can removal of the old component be billed separately?
Removal performed as part of replacing the component is part of the revision service. Code 27488 is for removal of a knee prosthesis without replacement.
Does allograft use change the code selection?
No. This code covers revision of one component with or without allograft; the component count remains the key distinction.
What documentation supports reporting this code?
The operative report should identify the existing knee prosthesis, the single component revised, the reason for revision, and the work performed.
How is bilateral reporting handled?
For a bilateral procedure reported with modifier 50, CMS pays 150% under the supplied fee schedule rule.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
