Epiphora due to insufficient drainage, right side

This code describes excessive tearing (epiphora) in the right eye resulting from an obstruction or dysfunction in the lacrimal drainage system. This prevents tears from properly draining into the nasal cavity, leading to overflow onto the cheek.

Apply this code when documentation specifies right-sided epiphora directly attributed to an issue with the lacrimal drainage system, such as a blocked tear duct or punctal stenosis. The physician's notes should clearly indicate the laterality and the underlying cause being insufficient drainage.

• Ensure documentation specifies "right side" for laterality; avoid using this code for bilateral or unspecified epiphora.
• Distinguish from epiphora due to excessive lacrimation (e.g., irritation, allergies), which would use different codes.
• Look for terms like "nasolacrimal duct obstruction," "punctal stenosis," or "canalicular blockage" in the right eye as supporting documentation.
