Acquired stenosis of unspecified nasolacrimal duct

This code describes a non-congenital narrowing or obstruction of the tear drainage system within the nose, where the specific side (right, left, or bilateral) is not documented. This condition typically leads to epiphora (excessive tearing) due to impaired tear outflow.

Use this code when the patient presents with symptoms of nasolacrimal duct obstruction, and the physician's documentation confirms an acquired stenosis without specifying laterality. This often occurs when the medical record simply states "nasolacrimal duct stenosis" or "tear duct obstruction" without further detail on the affected eye.

• Avoid using this code if laterality (right, left, or bilateral) is clearly documented; instead, select a more specific code from the H04.55 subcategory.
• Ensure the documentation explicitly states "acquired" or implies it by the absence of congenital origin.
• Consider querying the provider for clarification on laterality if possible, to allow for more precise coding.
