Summary & Overview
CPT 65222: Corneal Foreign Body Removal with Slit Lamp
CPT code 65222 denotes corneal foreign body removal performed with slit-lamp assistance, a common ophthalmic procedure to extract superficially embedded objects from the cornea. This code is nationally relevant because foreign body injuries to the eye are frequent, often urgent, and require timely, skilled removal to prevent infection, scarring, or vision loss. Accurate coding affects clinical workflow, facility routing, and claims adjudication for ambulatory and emergency eye care.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context and the typical sites where the service is delivered, followed by benchmarking and policy-focused content covering reimbursement patterns, payer-specific coverage considerations, and common billing practices. The publication outlines procedural nuances that influence coding choices, such as the use of slit-lamp visualization and whether the removal is superficially limited to the cornea.
This resource helps clinicians, coders, and revenue cycle professionals understand how CPT code 65222 is positioned within outpatient ophthalmic care, what to expect from major payers, and which clinical and administrative factors commonly affect claims for corneal foreign body removal. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 65222 describes removal of a foreign body from the cornea performed with the assistance of a slit lamp, a specialized microscope and light source used to visualize the eye. The procedure typically involves microscopic localization and extraction of a superficially embedded object from the corneal surface.
-
Service type: Minor ophthalmic surgical procedure for foreign body removal under slit-lamp visualization
-
Typical site of service: Ophthalmology clinic, eye emergency clinic, or outpatient ambulatory surgery setting when performed at the slit lamp
Clinical & Coding Specifications
Clinical Context
A 34-year-old carpenter presents to the ophthalmology clinic with acute onset ocular pain, tearing, foreign body sensation, and photophobia after a workplace incident where a metal fragment struck his right eye. Visual acuity is slightly reduced but intact. Slit lamp examination reveals a small superficial metallic foreign body embedded in the central cornea with localized staining on fluorescein exam. Topical anesthetic is instilled, and under slit lamp magnification the provider uses a sterile spud and jeweler’s forceps to remove the particle. Post-procedure care includes topical antibiotic drops, a pressure patch if indicated, and instructions for urgent follow-up if symptoms worsen.
Typical workflow:
-
Triage and history focused on mechanism of injury, tetanus status, and time since exposure.
-
Visual acuity and external eye exam.
-
Slit lamp exam with fluorescein staining to locate corneal foreign body and assess for rust ring or penetrating injury.
-
Application of topical anesthesia and, if needed, eyelid speculum.
-
Removal of the corneal foreign body at the slit lamp using appropriate sterile instruments.
-
Immediate post-removal exam for residual material, corneal defect size, and intraocular penetration.
-
Prescribe topical antibiotic and pain control; provide follow-up within 24–48 hours and return precautions.
