Summary & Overview
CPT 68811: Nasolacrimal Duct Probing Under General Anesthesia
CPT code 68811 covers diagnostic probing of the nasolacrimal duct performed with the patient under general anesthesia, with optional irrigation. This code is used for evaluation of suspected nasolacrimal duct obstruction or stricture when an anesthetized exam and potential irrigation are clinically necessary. Nationally, correct use of this code affects surgical coding accuracy, facility and professional fee allocation, and claims adjudication for ophthalmic and otolaryngology practices.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of the clinical context in which 68811 is reported, typical sites of service, common billing modifiers associated with surgical and anesthesia settings, and how payers commonly classify the service for coverage and reimbursement. The publication summarizes benchmark elements such as typical facility versus professional billing lines and highlights areas where coding clarity impacts claims processing.
This summary provides a national overview useful for coding professionals, billing managers, and clinical administrators seeking to align documentation and billing practices with payer expectations for nasolacrimal duct probing under general anesthesia. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 68811 describes a procedure performed with the patient under general anesthesia in which the provider probes the nasolacrimal duct to identify a possible obstruction or stricture. The procedure may include irrigation of the duct but irrigation is optional and not required for reporting the service.
-
Service type: Diagnostic probing of the nasolacrimal duct under general anesthesia
-
Typical site of service: Operating room or ambulatory surgery center where general anesthesia is administered
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or child with persistent epiphora (excessive tearing), recurrent dacryocystitis, or a history of nasolacrimal drainage dysfunction. The patient is evaluated in the ophthalmology or oculoplastic clinic with history, external ocular exam, and lacrimal irrigation/assessment. When canalicular probing/office irrigation is inconclusive or the child/uneasy adult requires immobilization, the patient is scheduled for probing of the nasolacrimal duct under general anesthesia in an ambulatory surgery center or hospital operating room. Under general anesthesia the surgeon introduces a lacrimal probe through the punctum into the canaliculus and nasolacrimal duct to identify a mechanical obstruction or stricture; irrigation with saline may be performed to confirm patency or dislodge debris. The procedure may be diagnostic and therapeutic in the same session; intraoperative findings determine whether additional intervention (stent placement, dacryocystorhinostomy) is planned or scheduled later. Typical perioperative workflow includes preoperative anesthesia evaluation, informed consent, topical antisepsis, probing/possible irrigation, documentation of duct patency, postoperative instructions, and brief recovery for discharge to home when stable.
