Other congenital malformations of lacrimal apparatus

This code signifies congenital anomalies affecting the lacrimal system that are not specifically classified elsewhere. These malformations can involve any part of the tear-producing and tear-draining structures, such as the lacrimal glands, puncta, canaliculi, lacrimal sac, or nasolacrimal duct. Such conditions are present at birth and can lead to issues like epiphora (excessive tearing) or dry eyes.

Use this code when documentation specifies a congenital malformation of the lacrimal apparatus that doesn't have a more specific ICD-10-CM code. This typically applies to conditions like congenital lacrimal gland hypoplasia/aplasia, accessory lacrimal glands, or other structural defects of the tear drainage system not otherwise specified as atresia or stenosis. Documentation should clearly state the congenital nature and the specific lacrimal structure involved.

• Ensure the documentation explicitly states "congenital" and identifies the lacrimal apparatus as the affected system.
• Differentiate from acquired lacrimal conditions, which would be coded elsewhere (e.g., H04.x series).
• Avoid using this code if a more specific congenital lacrimal anomaly code exists (e.g., Q10.5 for congenital stenosis/atresia of lacrimal duct).
