About 29884: Arthroscopic knee adhesion release
Arthroscopic knee adhesion release treats motion-limiting scar tissue, typically when postoperative stiffness requires surgical release rather than manipulation alone.
An orthopedic surgeon uses a knee arthroscope and instruments to release adhesions that restrict joint motion, often in a patient with arthrofibrosis after prior knee surgery. The procedure may include manipulation of the knee to improve motion. It is generally performed in an operating room, with the operative report identifying the adhesions and describing their release.
Report this code when the surgeon performs arthroscopic lysis of adhesions, not for manipulation alone or routine inspection of the joint. Documentation should support the presence of adhesions, the surgical work performed, and any manipulation. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When related endoscopies are performed together, endoscopy family pricing applies. For a bilateral procedure, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team surgery is not permitted.

29884 billing questions
When is this code more appropriate than manipulation alone?
Use it when the surgeon arthroscopically releases adhesions restricting knee motion. Manipulation without arthroscopic lysis is a different service, represented by code 27570.
Is manipulation included when performed with the adhesion release?
Yes. Manipulation may accompany the arthroscopic release; do not separately report code 27570 for that same manipulation in the same knee session.
What should the operative report support?
Document the motion-limiting adhesions, the arthroscopic release performed, and any manipulation. The report should make clear that the surgeon treated adhesions rather than performing only diagnostic inspection or another arthroscopic procedure.
How does the 90-day global period affect postoperative care?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
How is a bilateral procedure handled under the CMS facts?
For bilateral performance, modifier 50 is paid at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
