Lacrimal cyst, left lacrimal gland

This code signifies the presence of a fluid-filled sac or lesion originating from the left lacrimal gland. This condition is typically benign and results from an obstruction or developmental anomaly within the tear-producing gland.

Use this code when documentation clearly indicates a diagnosis of a cyst affecting the left lacrimal gland. This diagnosis is often made following an ophthalmic examination, imaging studies like MRI or CT, or surgical exploration.

• Ensure laterality is explicitly documented as "left" for the lacrimal gland cyst.
• Differentiate from cysts of the lacrimal sac (H04.3-) or other orbital cysts.
• If the cyst is congenital, consider additional codes from Q10.x for congenital malformations of the lacrimal apparatus.
