Acute dacryoadenitis, bilateral lacrimal glands

This code signifies an acute inflammatory condition affecting both lacrimal glands, characterized by sudden onset of pain, swelling, and redness in the outer upper eyelid region. It represents an active, short-term infection or inflammation of the tear-producing glands on both sides.

Apply this code when documentation clearly indicates a diagnosis of acute dacryoadenitis affecting both the right and left lacrimal glands. This typically occurs in the context of viral or bacterial infections, or inflammatory processes presenting with bilateral symptoms. Supporting documentation should include physician notes detailing the acute nature and bilateral involvement.

• Ensure documentation specifies "acute" and "bilateral" involvement; otherwise, consider laterality-specific or unspecified codes.
• Distinguish from chronic dacryoadenitis (H04.1-) or other lacrimal gland disorders.
• Code any underlying infectious agent (e.g., bacterial, viral) as an additional diagnosis, if identified and documented.
