CPT 68816: Probing and Balloon Dilation of Nasolacrimal Duct
Headline: CPT code 68816: Balloon Dilation of the Nasolacrimal Duct Addresses Tear-Drainage Obstruction
Lead: CPT code 68816 describes probing and balloon dilation of the nasolacrimal duct to correct ductal stricture and restore tear drainage. The minimally invasive procedure is performed via catheter-based balloon dilation and is commonly delivered in outpatient surgical settings.
CPT code 68816 represents a targeted, procedural solution for nasolacrimal duct obstruction, a condition that can cause chronic tearing and recurrent eye irritation. Nationally, this code matters because it captures a distinct endoscopic/balloon intervention that differs from traditional nasolacrimal surgery and influences site-of-service and device-use considerations. Key payers addressed in standard analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context of the procedure, where it is typically performed, and how the code is used to represent balloon catheter dilation of the nasolacrimal duct. The publication summarizes common billing modifiers and related administrative considerations, offers benchmarking context where available, and highlights relevant coding relationships and policy updates. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 68816 describes probing and balloon dilation of the nasolacrimal duct to correct stricture or narrowing of the duct. The procedure involves passing a catheter through the nasolacrimal passage and dilating the duct with a balloon to restore tear drainage from the eye into the nasal cavity.

Service type: Minor ambulatory surgical procedure to relieve nasolacrimal duct obstruction

Typical site of service: Outpatient ambulatory surgery center or hospital outpatient department
Clinical & Coding Specifications
Clinical Context
A 62-year-old female presents to an outpatient ophthalmology clinic with months of persistent tearing (epiphora) and intermittent mucopurulent discharge from the right eye. Conservative treatments including topical antibiotics and lacrimal sac massage provided only transient relief. Lacrimal irrigation demonstrates high-grade resistance to saline passage at the nasolacrimal duct. After counseling, the patient is scheduled for a balloon dacryoplasty (nasolacrimal duct balloon dilation) under monitored anesthesia care.
The clinical workflow: pre-procedure evaluation by the ophthalmologist or oculoplastic surgeon includes a focused ocular history, nasal examination to exclude intranasal pathology, and assessment of comorbidities that affect anesthesia. In the procedure suite or ambulatory surgery center, local anesthesia with sedation or general anesthesia is administered. The provider cannulates the canaliculus, threads a catheter through the nasolacrimal duct into the nasal cavity, advances a balloon catheter to the stricture, inflates the balloon to dilate the lumen, then deflates and removes the catheter. Post-procedure instructions include topical antibiotics, nasal care, activity restrictions, and follow-up to assess symptom resolution and patency with repeat irrigation if indicated. Typical site of service is an ambulatory surgery center or hospital outpatient department; the service type is minor surgical endoscopic/interventional ophthalmic procedure for lacrimal drainage system (balloon dacryoplasty).
