About 27429: Combined knee ligament reconstruction
Reports open intra-articular plus extra-articular ligament reconstruction in one knee operation for instability requiring both forms of stabilization.
This code describes reconstruction of knee ligament stabilizers using both an intra-articular and an extra-articular component. Orthopedic surgeons commonly perform the procedure for substantial knee instability when stabilization is needed inside and outside the joint, such as an intra-articular cruciate ligament reconstruction combined with extra-articular augmentation. It is generally performed in an operating room, often for complex ligament injuries or persistent instability.
Report the code when the operative documentation supports both components of the reconstruction; an isolated intra-articular or extra-articular reconstruction belongs to a different code in the family. The note should identify the reconstructed structures and describe the work performed in each location. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 bilateral reporting is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

27429 billing questions
When is this code selected instead of 27427 or 27428?
Use this code when the operation includes both intra-articular and extra-articular ligament reconstruction. Code 27427 describes extra-articular reconstruction, while 27428 describes intra-articular reconstruction.
Can this code be reported with an arthroscopic ACL reconstruction code?
The operative report should establish whether the service represents the combined intra- and extra-articular reconstruction described here or a separately reportable service. Do not separately report overlapping work merely because different techniques or incisions were used.
What documentation supports reporting the combined reconstruction?
Document the instability being treated, the ligament structures addressed, and the intra-articular and extra-articular reconstructive work performed. The record should make clear that both components were completed in the same operation.
Are routine postoperative visits separately reported?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How does CMS handle multiple procedures in the same session?
The highest-valued procedure is paid in full, and other procedures are paid at 50%. Modifier 50 bilateral reporting is paid at 150%.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
