ICD-10 Code H04.432 – Chronic lacrimal mucocele of left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.432 – Chronic lacrimal mucocele of left lacrimal passage
What it is
This code identifies a chronic mucus-filled dilation in the left lacrimal drainage passage. It reflects a long-standing obstruction or blockage in the tear pathway on the left side.
Clinical signs
Typical findings include persistent swelling near the medial canthus, tearing, or a palpable cystic mass along the lacrimal sac area. Clinical features vary; refer to documentation.
When to use this code
Use H04.432 when the record clearly states a chronic lacrimal mucocele involving the left lacrimal passage. It is appropriate when the provider documents a chronic obstructive lesion or mucus retention in the left tear drainage system. Check documentation if laterality or chronicity is not explicit.
Do not use for
Do not use this code for acute dacryocystitis, nonspecific tearing, or lacrimal disorders without documented chronic mucocele. If the side is not left, choose the correct laterality code.
Coding tip
Verify both chronicity and left-sided documentation before assigning H04.432.
