Summary & Overview
CPT 65865: Incisional Lysis of Anterior Segment Adhesions for Glaucoma
CPT code 65865 designates an incisional ophthalmic procedure to sever adhesions or goniosynechiae in the anterior segment of the eye for treatment of glaucoma. This code captures a targeted surgical approach to restore aqueous outflow pathways when peripheral anterior synechiae or other adhesions contribute to elevated intraocular pressure. Nationally, accurate coding of such procedures supports proper clinical documentation, enables consistent tracking of glaucoma surgical patterns, and informs payment and quality measurement for anterior segment glaucoma care.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent of the code, typical sites of service, and the common contexts in which the procedure is reported. The publication outlines benchmarks and coding considerations relevant to facility and professional billing, highlights potential policy updates that affect coverage and bundling, and provides clinical context that clarifies when the incisional lysis of adhesions is used versus alternative glaucoma procedures.
This national-oriented summary is intended for health plan analysts, coding professionals, and clinical leaders who need a clear reference for CPT code 65865, its clinical role in glaucoma management, and the payer landscape that commonly covers the service.
Billing Code Overview
CPT code 65865 describes an incisional procedure to sever adhesions or goniosynechiae in the anterior segment of the eye performed to treat glaucoma. The technique involves surgical incision of adhesions that obstruct aqueous outflow, with the clinical goal of improving intraocular fluid dynamics and reducing intraocular pressure.
Service type: Ophthalmic surgical procedure — anterior segment adhesion/goniosynechiae lysis
Typical site of service: Ambulatory surgical center or hospital outpatient department
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with a history of primary angle-closure glaucoma presents with progressive intraocular pressure elevation despite maximal tolerated topical therapy. Slit-lamp examination and gonioscopy demonstrate focal peripheral anterior synechiae (PAS) obstructing the trabecular meshwork in the anterior chamber angle. The ophthalmologist schedules a targeted anterior segment incisional procedure to sever adhesions/goniosynechiae to restore aqueous outflow and reduce intraocular pressure.
The clinical workflow includes preoperative evaluation (history, visual acuity, intraocular pressure measurement, gonioscopy, and anterior segment imaging as needed), informed consent documenting risks and alternatives, perioperative topical or local anesthesia, intraoperative gonioscopic visualization and microsurgical incision of adhesions (CPT 65865), intraoperative assessment of angle opening, and postoperative follow-up visits to monitor intraocular pressure, inflammation, and wound healing. Typical postoperative management includes topical antibiotics and corticosteroids and planned IOP checks at day 1, week 1, and subsequent visits to guide glaucoma therapy adjustments.
