About 27430: Quadricepsplasty for knee stiffness
Reports surgical lengthening or release of contracted quadriceps muscle to improve knee flexion, often for persistent post-traumatic stiffness.
A quadricepsplasty releases or lengthens a shortened quadriceps mechanism that is restricting knee flexion. Orthopedic surgeons commonly perform it for persistent stiffness after trauma, such as a distal femur fracture, when scarred or contracted thigh muscle limits motion. It is an open operative treatment, generally performed in a hospital or ambulatory surgical setting, rather than a manipulation or ligament reconstruction.
Report 27430 when the operative work is quadricepsplasty; the operative note should identify the contracture, its effect on knee motion, and the muscle release or lengthening performed. The code has a 90-day global period, including 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27430 billing questions
When is quadricepsplasty appropriate instead of knee manipulation?
Report 27430 for operative release or lengthening of contracted quadriceps muscle. Code 27570 describes manipulation of the knee under anesthesia, not quadricepsplasty.
How is this different from a knee capsular release?
Quadricepsplasty addresses restriction from contracted quadriceps muscle. A capsular procedure such as 27435 addresses the knee capsule.
What documentation supports 27430?
Document the quadriceps contracture, the resulting restriction in knee flexion, and the operative release or lengthening performed.
Can modifier 50 be used for bilateral quadricepsplasty?
Yes. CMS identifies this as a bilateral procedure; bilateral reporting with modifier 50 is paid at 150%.
How does the 90-day global period affect postoperative claims?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation.
