Is it appropriate to separately report the repair of the interphalangeal joint collateral ligament ( 26540 ) when performed on the same joint as an interphalangeal joint arthroplasty with implant ( 26536 )? The radial collateral ligament was previously disrupted, and the ulnar collateral ligament was released during the procedure. Both were reattached after the permanent implant was placed, along with a volar plate reattachment. Some surgical descriptions of interphalangeal joint arthroplasty procedures describe release of the ligaments to access the joint space, but others say the collateral ligaments are spared. ...

Article Overview

This article reviews a coding question involving hand and finger surgery, specifically the relationship between interphalangeal joint arthroplasty and collateral ligament repair on the same joint. It is written for medical coders, billers, and reimbursement professionals who need to understand how bundled components of a surgical procedure are addressed in coding guidance. The discussion focuses on procedure reporting, related operative details, and the rationale behind whether separate reporting is appropriate.

Why This Topic Matters

Accurate reporting of bundled versus separately reportable surgical components affects claim integrity and consistent coding for hand procedures. This guidance helps reduce coding variation when operative reports include ligament release, reattachment, and implant placement during the same operation.

Codes Discussed

• CPT: 26540
• CPT: 26536
