Summary & Overview
CPT 65450: Corneal Lesion Removal by Destructive Technique
CPT code 65450 covers destruction of a corneal lesion using cryotherapy, photocoagulation, or thermocauterization, with cryotherapy being the most common modality. This procedure code captures minor ophthalmic surface surgery focused on removing focal corneal lesions that may be symptomatic, interfering with vision, or require tissue removal for diagnostic or therapeutic reasons. Nationally, accurate coding of CPT code 65450 affects clinical documentation, billing consistency, and aggregated utilization counts for ophthalmic outpatient care.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service where the work is performed, and the types of benchmarks and policy items commonly associated with this code. The publication summarizes typical billing considerations and common modifiers used with procedural ophthalmic codes, highlights implications for outpatient ophthalmology practice patterns, and notes areas where payers commonly set prior authorization or documentation expectations.
The content is intended to inform coding staff, practice managers, and policy audiences about the clinical and billing identity of CPT code 65450, expected service settings, and the broader administrative and reimbursement considerations relevant to this specialty procedure.
Billing Code Overview
CPT code 65450 describes removal of a corneal lesion by destructive techniques, including cryotherapy, photocoagulation, or thermocauterization. Cryotherapy is the most commonly used method for lesion destruction. The procedure involves targeted destruction of corneal tissue to remove benign or pathologic surface lesions.
Service Type: Minor corneal lesion destruction / ophthalmic surface procedure
Typical Site of Service: Ophthalmology clinic, ambulatory surgical center, or office-based procedure suite
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents to the ophthalmology clinic with a superficial, elevated corneal lesion causing localized irritation and foreign body sensation. Slit-lamp examination confirms a small, well-demarcated lesion consistent with a benign epithelial or subepithelial corneal growth (e.g., Salzmann nodule, pannus, epithelial inclusion). After topical anesthesia and antisepsis, the provider performs lesion destruction using cryotherapy applied to the corneal surface with controlled freeze-thaw cycles to ablate the lesion. The procedure is brief, performed under sterile conditions at an ambulatory ophthalmology clinic or outpatient surgical center. Post-procedure, the patient receives topical antibiotic and anti-inflammatory drops, instructions for eye protection, and a scheduled follow-up visit to assess healing and to determine if additional therapy (repeat cryotherapy, excision, or adjunctive photocoagulation) is required.
