CPT code 25800 denotes wrist arthrodesis performed without a bone graft, a definitive surgical option to fuse wrist bones for pain relief, stabilization, or deformity correction. Nationally, this code captures an important set of upper-extremity orthopedic interventions with implications for surgical utilization, perioperative planning, and post-acute care pathways.

Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and coding description, typical sites of service, and the kinds of benchmarks and policy considerations that commonly inform coverage and payment: utilization benchmarks for wrist fusion procedures, common modifier patterns and billing considerations, and clinical context for when fusion without bone graft is indicated.

This publication provides practical reference material for billing and coding teams, revenue cycle managers, and policy analysts seeking a national perspective on CPT code 25800. It summarizes where the procedure is typically performed, who pays for it at scale, and what areas—such as coding specificity and documentation—warrant attention in payer contracts and policy updates.
