Epiphora due to insufficient drainage, bilateral

This code signifies excessive tearing (epiphora) affecting both eyes, specifically caused by an obstruction or inadequacy in the lacrimal drainage system. This means the tears are produced normally but cannot drain properly, leading to overflow onto the cheek.

Use this code when documentation clearly indicates bilateral epiphora resulting from an issue with tear drainage, such as lacrimal duct obstruction, punctal stenosis, or canalicular blockage. Supporting documentation should specify the laterality and the underlying cause being insufficient drainage.

• Ensure the documentation explicitly states "bilateral" and attributes the epiphora to insufficient drainage, not excessive tear production.
• Distinguish from codes for epiphora due to excessive lacrimation (e.g., H04.1xx) or unspecified causes.
• Look for specific diagnoses like dacryostenosis or punctal occlusion to support the "insufficient drainage" etiology.
