Procedure Overview
This family covers procedures that widen a naturally narrow or obstructed passage in or around the eye, most commonly the tear drainage system. When the nasolacrimal duct or the small punctal openings at the inner eyelid become narrowed by scarring, chronic inflammation, or congenital underdevelopment, tears cannot drain normally into the nose, leading to persistent watering, discomfort, and sometimes recurrent infection.
A dilation procedure uses a probe, balloon catheter, or similar instrument to gently stretch the narrowed segment open, restoring normal tear flow without removing tissue or leaving a permanent implanted device behind. It is a frequently performed outpatient treatment, particularly in infants with congenital tear duct blockage and in adults with age-related or scar-related narrowing.
Anatomy & Axis Detail
Lacrimal Duct, Left
The left lacrimal duct is dilated when scarring or stenosis along its course, from the punctum through the canaliculus to the nasolacrimal duct proper, obstructs normal tear drainage and produces persistent watering of the eye. Probing with calibrated instruments is the traditional approach, particularly effective in congenital cases where a membranous obstruction at the valve of Hasner has failed to open spontaneously, while balloon catheter dilation is favored in adults with acquired fibrotic strictures, often as an alternative to bypass surgery. The duct's passage through the bony nasolacrimal canal limits the space available for instrumentation and raises the risk of mucosal trauma or false tracking if the stricture is tight or tortuous. Coding should reflect that the native duct lumen was enlarged in place, not replaced or bypassed.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Coding & Documentation
Coding requires documentation identifying the specific narrowed structure being opened, such as the lacrimal punctum, canaliculus, or nasolacrimal duct, along with the method used to achieve dilation, since the approach and any device used affect code selection. The note should confirm the intent was to expand an existing passage rather than create a new one or leave a stent permanently in place, which would shift the case toward Bypass or Insertion instead. A common error is coding a lacrimal duct probing that also involves temporary stent placement purely as Dilation when the stent's own placement and later removal may warrant separate consideration under insertion and removal conventions.
