What 27405 covers

This code describes an operation to restore a torn knee collateral ligament or capsule through primary repair, such as suturing or reattaching repairable tissue. An orthopedic surgeon typically performs the procedure in an operating room for a knee injury where the operative plan is direct repair rather than graft-based reconstruction. The operative report should identify the repaired structure and describe the repair performed.

Select this code for primary repair of collateral ligament or capsular tissue; a cruciate ligament repair or a reconstruction calls for a different code. The day before surgery and 90 days of related postoperative care are included in its 90-day global period. When multiple procedures occur 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.

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.

27405 billing questions

When should 27405 be chosen instead of 27407?

Use 27405 for primary repair of a collateral ligament or capsule. Code 27407 is for primary repair involving a cruciate ligament.

When does 27409 apply?

Use 27409 when the operative service is primary repair of both collateral and cruciate ligaments. It distinguishes that combined repair from a collateral-only repair reported with 27405.

Is primary repair different from ligament reconstruction?

Yes. This code represents direct primary repair of collateral ligament or capsular tissue; a ligament reconstruction is a different service, such as the reconstruction represented by 27427.

What postoperative care is included?

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

How is bilateral repair reported?

For repair of both knees, modifier 50 is paid at 150% under the bilateral rule.

Can an assistant or co-surgeon be paid?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
