Summary & Overview
HCPCS Level II S0812: Phototherapeutic Keratectomy (PTK)
HCPCS Level II code S0812 designates phototherapeutic keratectomy (PTK), an excimer-laser corneal surface procedure used to remove superficial corneal pathology such as recurrent erosions, superficial scars, and certain dystrophies. Nationally, this procedure matters because it addresses visual impairment and symptomatic corneal disease that often require outpatient surgical care and coordination between ophthalmology providers and payers. Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context of PTK, typical sites of service, and the payer landscape relevant to coverage and billing practices. The publication summarizes common modifiers observed for surgical ophthalmology, highlights where data is not available in the input, and outlines the types of benchmarks and policy updates that would be relevant for stakeholders. This summary is intended to help revenue cycle managers, coding professionals, and policy analysts quickly understand what S0812 represents, which payers are typically involved, and what additional data elements (utilization benchmarks, authorization requirements, and diagnosis linkage) are commonly sought when assessing PTK billing across the national market.
Billing Code Overview
HCPCS Level II code S0812 represents phototherapeutic keratectomy (PTK), a surgical procedure using excimer laser ablation to treat corneal surface disorders. The service type is ophthalmic surgical procedure directed at the cornea. The typical site of service is an ambulatory surgical center or hospital outpatient department, with procedures performed by ophthalmologists specializing in corneal surgery.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with recurrent superficial corneal scarring and symptomatic irregular astigmatism presents to an ophthalmology clinic for evaluation. Symptoms include decreased vision, glare, and discomfort refractory to conservative treatment (lubricants, contact lens refitting). After slit-lamp examination, corneal topography, and pachymetry confirm anterior stromal irregularity and sufficient residual stromal bed, the ophthalmologist schedules a phototherapeutic keratectomy (PTK) to remove superficial opacities and smooth the anterior corneal surface.
The clinical workflow includes preoperative evaluation (visual acuity, refraction, corneal imaging, informed consent), perioperative topical anesthesia and antisepsis, performing excimer laser ablation of superficial corneal tissue under sterile conditions in an ambulatory surgical center or ophthalmology outpatient suite, placement of a bandage contact lens post-procedure, and postoperative topical antibiotics and corticosteroids with scheduled follow-up visits for epithelial healing and refractive assessment. Typical sites of service are an ambulatory surgical center (ASC) or an ophthalmologist’s outpatient ophthalmic procedure room equipped with an excimer laser.
