Summary & Overview
CPT 67220: Laser Photocoagulation of Localized Choroidal Lesion
CPT code 67220 denotes laser photocoagulation directed at a localized choroidal lesion to ablate abnormal blood vessel growth in the vascular layer of the eye. This procedure is an established ophthalmic treatment for focal choroidal neovascularization and other localized choroidal abnormalities that pose a risk to visual function. Nationally, accurate coding for this intervention impacts clinical tracking, reimbursement, and utilization monitoring for retinal and choroidal disease therapies. Key payers included in this analysis are 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 service type. The publication also summarizes payer coverage patterns and benchmark considerations, outlines common billing modifiers, and situates the code within ophthalmic procedural coding practice. Clinical context explains when laser photocoagulation of the choroid is used relative to other retinal therapies. Policy implications address coding specificity and documentation elements that commonly affect claim adjudication. Data limitations and missing elements from the input are identified where applicable. The briefing is intended for clinicians, billing professionals, and policy analysts seeking a practical, national-level summary of CPT code 67220.
Billing Code Overview
CPT code 67220 describes treatment of a localized choroidal lesion using a laser beam to destroy abnormal blood vessel growth in the choroid, the vascular middle layer of the eye. The procedure targets abnormal neovascularization or focal choroidal lesions that threaten vision by delivering photocoagulation directly to the affected area.
Service type: Laser photocoagulation of choroidal lesion
Typical site of service: Ophthalmology clinic or ambulatory surgical center, where ocular laser procedures are performed under monitored conditions.
Clinical & Coding Specifications
Clinical Context
A typical patient is a 70-year-old with new-onset blurred central vision and metamorphopsia in one eye. Ophthalmic examination reveals subretinal hemorrhage and pigment epithelial detachment consistent with a focal choroidal neovascular membrane (CNV). Optical coherence tomography (OCT) and fluorescein angiography confirm a localized choroidal lesion amenable to focal laser photocoagulation. The clinical workflow: informed consent and preprocedure counseling; topical anesthesia and pupil management in an outpatient ophthalmology clinic or ambulatory surgical center; application of a slit-lamp-mounted or indirect laser to deliver confluent burns to the targeted choroidal neovascularization; immediate postprocedure assessment of intraocular pressure and anterior segment; discharge with topical anti-inflammatory and antibiotic drops when indicated; scheduled follow-up for vision assessment and imaging to monitor treatment response and detect recurrence.
