CPT 65400 Corneal Surface Excision Reimbursement

CPT code 65400 represents a surgical procedure for excision of a thin layer from the corneal surface to remove lesions such as masses or scar tissue, excluding pterygium removal. Nationally, this code is relevant for ophthalmology surgical practices, ambulatory surgery centers, and hospital outpatient departments that provide corneal lesion management. It reflects a targeted anterior corneal procedure with implications for coding accuracy, site-of-service designation, and reimbursement for ocular surface surgery.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical context for when CPT code 65400 is used, an explanation of typical settings for the service, and an outline of the administrative elements that affect billing for corneal surface excisions. The publication summarizes common modifiers and administrative considerations when available, and highlights areas where institutions commonly track utilization and authorization needs.

Billing Code Overview

CPT code 65400 describes an excision of a thin layer from the surface of the cornea to remove a mass, scar tissue, or other lesion, explicitly excluding removal of a pterygium. This procedure targets the anterior corneal surface that helps focus light onto the lens.

Service type: Corneal surface excision (superficial corneal lesion removal)
Typical site of service: Ophthalmology outpatient surgical suite or ambulatory surgery center; may also be performed in hospital outpatient settings when clinically indicated.

Data not available in the input.

Clinical Context

A 62-year-old patient presents to the ophthalmology clinic with a slowly enlarging, well-demarcated superficial corneal lesion causing localized irritation and decreased visual acuity. Slit-lamp examination reveals a superficial corneal mass confined to the epithelial and anterior stromal layers without full-thickness involvement. The provider discusses options and schedules an outpatient superficial keratectomy to excise the lesion for symptomatic relief and histopathology.

The clinical workflow: the patient undergoes preoperative screening and informed consent, topical or local anesthesia is administered in an ambulatory surgical center or office-based procedure room, and the ophthalmic surgeon performs a superficial keratectomy to remove the lesion from the corneal surface. Tissue is submitted for pathology if appropriate. Immediate postoperative care includes topical antibiotics and/or steroid drops, brief observation for complications, and follow-up visits to monitor healing and visual recovery.
