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.
