AnnexMed’s “Knee Arthroscopy CPT Codes for 2025” is a comprehensive resource for orthopedic coders, billing departments, surgeons, and audit teams who must stay current to ensure accurate procedure reporting, reimbursement, and compliance. The article delves deeply into three major CPT codes relevant to knee arthroscopy:

CPT 29875: Limited synovectomy – code used when synovectomy is performed in only one compartment of the knee (e.g. medial compartment) and as a separate procedure.
CPT 29876: Major synovectomy – applies when synovectomy spans two or more compartments.
CPT 29877: Articular cartilage debridement (chondroplasty) – when cartilage surfaces rather than synovial tissue are the target. https://annexmed.com/knee-arthroscopy-cpt-codes.
