Stenosis of left lacrimal sac

This code describes a narrowing or obstruction of the lacrimal sac located in the inner corner of the left eye. This condition impedes the normal drainage of tears, leading to epiphora (excessive tearing) and potential recurrent infections (dacryocystitis).

Use this code when documentation specifies stenosis of the left lacrimal sac, often presenting with symptoms like persistent watery eye, discharge, or inflammation. This diagnosis is typically made after an ophthalmological examination, possibly including lacrimal irrigation or dacryocystography.

• Ensure the laterality (left) is clearly documented.
• Distinguish from congenital lacrimal duct obstruction (Q10.5) or other lacrimal gland disorders.
• Code any associated dacryocystitis (H04.3-) or other complications separately.
