Acute dacryoadenitis, left lacrimal gland

This code signifies an acute inflammatory process affecting the left lacrimal gland, characterized by sudden onset of pain, swelling, and redness in the outer part of the upper eyelid. It represents an infection or inflammation of the tear-producing gland, distinct from other ocular or adnexal conditions.

Apply this code when documentation clearly indicates a diagnosis of acute dacryoadenitis specifically affecting the left lacrimal gland. This typically occurs in patients presenting with unilateral, rapid-onset symptoms localized to the left upper outer eyelid area. Supporting documentation should include physician notes detailing the acute nature and laterality.

• Ensure the documentation specifies "acute" and "left" to differentiate from chronic or right-sided conditions.
• Do not confuse with dacryocystitis (inflammation of the lacrimal sac) or other eyelid inflammatory conditions.
• Look for associated signs and symptoms like pain, erythema, and swelling in the superotemporal orbit.
