Bone bank graft in midcarpal fusion
A mid-carpal arthrodesis with scaphoid excision was performed due to left wrist radioscaphoid and mid-carpal arthritis. After the incision was made and dissection was taken down to the carpal joint, the scaphoid was fragmented and removed. The lunate was brought into neutral tilt and temporarily pinned. Demineralized bone matrix (DBM) allograft putty was placed into the mid-carpal articulation and the remainder of the hardware was placed. Since bone bank graft and bone graft substitutes are generally inherent to musculoskeletal procedures and not separately reported, is it appropriate to assign CPT code 25820 , Arthrodesis, wrist; limited, without bone graft (eg, intercarpal or radiocarpal), for the intercarpal fusion? Or since the narrative of code 25820 specifically states “without bone graft” is the assignment of an unlisted code more appropriate? ...

Article Overview
This premium article addresses a wrist fusion coding question involving a limited midcarpal arthrodesis, scaphoid excision, and the use of demineralized bone matrix allograft putty. It is aimed at coders, auditors, and orthopedic billing staff who need to compare the documented procedure against CPT arthrodesis reporting conventions and determine whether a standard code or an unlisted approach is being considered. The article focuses on how operative documentation is interpreted in the context of musculoskeletal surgery and graft-related reporting.
Why This Topic Matters
Accurate CPT selection for wrist arthrodesis affects claim integrity, coding compliance, and consistent reporting of orthopedic procedures when graft material is documented.
