Chronic dacryocystitis of bilateral lacrimal passages

This code signifies a persistent, long-standing inflammation of the tear drainage system affecting both eyes. It indicates a chronic infection or obstruction of the nasolacrimal ducts, leading to symptoms like excessive tearing, discharge, and swelling in the medial canthal region.

Apply this code when documentation explicitly states "chronic dacryocystitis" affecting "bilateral" lacrimal passages. This is appropriate for patients presenting with ongoing symptoms of tear duct obstruction or infection in both eyes, confirmed by clinical examination or imaging.

• Ensure documentation specifies "chronic" and "bilateral" to support this code; otherwise, consider acute or unilateral codes.
• Do not confuse with codes for acute dacryocystitis (H04.3-) or other lacrimal gland disorders.
• If an underlying cause (e.g., specific infection, trauma) is identified, code it as a secondary diagnosis.
