CPT code 67120 identifies the surgical removal of previously implanted extraocular material from the posterior segment of the eye.

Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical definition and typical settings, a summary of payer coverage patterns and common billing modifiers, and context on how the procedure fits into ophthalmic surgical practice. The publication highlights benchmark considerations for coding and claims submission, describes typical sites of service (hospital operating room and ambulatory surgical center), and summarizes policy considerations that affect prior authorization and documentation. Data not available in the input are noted where applicable. This analysis is intended to inform coding professionals, billing teams, and policy analysts about the clinical scope and payer relevance of CPT code 67120 on a national level.
