CPT code 1012T identifies a minimally invasive intraocular procedure that creates one or more small openings from inside the eye in the sclera or trabecular meshwork, with optional injection of antifibrotic agents. This procedure addresses aqueous outflow to lower intraocular pressure and is increasingly relevant as glaucoma management expands toward microinvasive surgical options. Nationally, the code matters because it defines how payers and providers classify and bill for evolving glaucoma interventions that sit between topical/interventional therapy and traditional filtration surgery.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and service setting, plus benchmarks and policy-relevant material where available. The publication highlights what to expect in coverage patterns, coding contexts, and clinical documentation needs tied to device-based intraocular outflow procedures.

The report outlines: (1) the clinical procedure and typical sites of service; (2) how the code fits into procedural coding frameworks and billing workflows; and (3) areas where payers commonly focus prior authorization and coverage criteria. Data not provided in the input are noted as unavailable.
