What code(s) would be reported for arthrodesis of two interphalangeal joints?

The correct codes for arthrodesis of two interphalangeal joints are indeed 26860 and 26861. These codes are specifically designated for fusion procedures involving the phalanges of the fingers and toes.

Code 26860 describes the arthrodesis of one interphalangeal joint, while code 26861 is used for an additional interphalangeal joint when more than one joint is arthrodesed. Since the question specifies that two interphalangeal joints are being fused, both codes are correctly reported together to accurately reflect the surgical procedure performed.

Understanding the anatomy involved and the specific coding for the type of joints is critical in correctly assigning the CPT codes. Each code captures the essential elements of the procedures, ensuring that the documentation aligns with the coding guidelines for surgical procedures in the context of orthopedic surgery. Moreover, this choice of codes effectively communicates the extent of the surgery performed, which is vital for billing and insurance purposes.

The other choices provided pertain to different surgical procedures or anatomical areas which are not relevant to arthrodesis of the interphalangeal joints, hence why they would not be applicable in this case.
