Chronic dacryocystitis of right lacrimal passage

This code signifies a persistent inflammation of the tear sac (dacryocystitis) affecting the right eye's lacrimal drainage system. This chronic condition typically results from an obstruction in the nasolacrimal duct, leading to tear stagnation and recurrent infection.

Apply this code when documentation indicates a long-standing or recurrent infection of the right lacrimal sac. Supporting documentation should specify chronicity and laterality, often including symptoms like epiphora, discharge, and tenderness in the medial canthal area.

• Ensure documentation clearly specifies "chronic" dacryocystitis and laterality (right eye).
• Distinguish from acute dacryocystitis (H04.311) which has a sudden onset and shorter duration.
• If an underlying cause for the obstruction is identified, code it as a secondary diagnosis.
