ICD-10 Code H04.572 – Stenosis of left lacrimal sac (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.572 – Stenosis of left lacrimal sac
What it is
H04.572 identifies narrowing of the left lacrimal sac, the tear-drainage space in the inner corner of the eye. This code is used when the left-sided sac is stenotic and tear outflow is impaired.
Clinical signs
Common findings include tearing, recurrent discharge, and swelling near the medial canthus. Clinical features vary; refer to documentation, especially if exam or imaging describes reduced drainage from the left lacrimal system.
When to use this code
Use this code when the clinician documents stenosis of the left lacrimal sac as the diagnosed condition. It also fits when evaluation confirms left-sided tear drainage obstruction at the sac level, even if symptoms are described more generally as epiphora.
Do not use for
Do not use H04.572 for right-sided or bilateral lacrimal sac disease. Also avoid it when the record only mentions nonspecific tearing without documentation of left lacrimal sac stenosis.
Coding tip
Confirm laterality and the exact anatomic site in the note before assigning H04.572.
