What 29873 covers

This procedure uses a knee arthroscope and instruments to release tight tissue along the outer side of the patella, reducing lateral restraint when patellar tracking or tilt is the surgical problem. Orthopedic surgeons perform it in an operating room, commonly for symptomatic patellar maltracking or lateral compression. The operative report should identify the lateral retinacular release rather than only diagnostic inspection or work on cartilage, synovium, or meniscus.

Report the arthroscopic release actually performed, supported by the indication, laterality, arthroscopic findings, and operative description. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. If related endoscopies are performed together, endoscopy-family pricing applies. For bilateral reporting, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

29873 billing questions

How does this differ from an open lateral release?

This code describes release performed arthroscopically. CPT 27425 is the open approach to lateral retinacular release.

Can it be reported with a meniscectomy or chondroplasty?

It may be reported with separately performed arthroscopic work when the operative report supports each service. CMS applies endoscopy-family pricing when related endoscopies are performed together.

What does the 90-day global period include?

The global period includes the day-before preoperative visit and 90 days of related postoperative care.

How is bilateral surgery reported?

For a bilateral procedure, modifier 50 is paid at 150% under the CMS rule for this code.

May an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this code. Co-surgeons are paid only with supporting documentation; 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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
