Stenosis of unspecified lacrimal sac

This code signifies a narrowing or obstruction of the lacrimal sac, the small reservoir for tears located in the inner corner of the eye. This stenosis impedes the normal drainage of tears, potentially leading to epiphora (excessive tearing) or dacryocystitis (inflammation of the lacrimal sac). The "unspecified" nature indicates that the laterality (right, left, or bilateral) is not documented.

Use this code when documentation clearly indicates a diagnosis of lacrimal sac stenosis, but the medical record does not specify which eye is affected. This code is appropriate when the physician's notes describe symptoms such as persistent tearing or discharge, and diagnostic imaging or examination confirms an obstruction at the lacrimal sac level without laterality.

• Avoid using this code if laterality (right, left, or bilateral) is documented; instead, select the more specific H04.571, H04.572, or H04.573.
• Ensure the documentation specifies "lacrimal sac" stenosis, not lacrimal duct or punctum, to avoid miscoding.
• Consider sequencing this code with codes for associated conditions like epiphora (H04.2-) or dacryocystitis (H04.3-) if present and documented.
