Carpometacarpal arthroplasty

Patient with right thumb metacarpophalangeal (MCP) joint instability, carpometacarpal (CMC) osteoarthritis, and wrist scaphotrapeziotrapezoidal (STT) arthritis presents for treatment of the thumb and wrist. A CMC arthroplasty was performed along with excision of the trapezoid bone. Arthrodesis was also performed on the MCP joint using K-wires to immobilize the joint. Fluoroscopic images showed the hardware utilized was placed appropriately. If a patient has a thumb CMC arthroplasty, MCP joint arthrodesis and excision of the trapezoid bone, for wrist STT arthritis and not for the CMC osteoarthritis, can excision of the trapezoid bone be separately reported?

Article Overview

This premium article addresses a hand surgery coding scenario involving thumb carpometacarpal arthroplasty with additional procedures at the metacarpophalangeal joint and trapezoid bone. It focuses on how the case is presented for coding review, the presence of an NCCI edit, and the broader issue of when separate reporting and modifier use are being considered. The content is most relevant to orthopedic, hand surgery, and coding professionals reviewing CPT-based reporting questions.

Hands and upper-extremity procedures often involve multiple closely related operative services, and coding accuracy can affect claim edits and reporting integrity. This article helps readers evaluate a specific multi-procedure scenario in the context of CPT and NCCI edit review without needing to infer the full coding guidance from the title alone.
