Stenosis of right lacrimal sac

This code signifies a narrowing or obstruction of the right lacrimal sac, which is a component of the tear drainage system. This stenosis impedes the normal flow of tears, leading to epiphora (excessive tearing) and potential recurrent infections of the lacrimal sac (dacryocystitis).

Apply this code when documentation explicitly states stenosis of the right lacrimal sac. This condition is often diagnosed following an ophthalmological examination, dacryocystography, or during evaluation for chronic tearing or recurrent eye infections affecting the right eye.

• Ensure laterality is clearly documented as "right" to support this specific code.
• Distinguish from stenosis of the nasolacrimal duct (H04.56-) or other parts of the lacrimal drainage system.
• Consider coding any associated dacryocystitis (H04.3-) or epiphora (H04.2-) as secondary diagnoses.
