Acute dacryocystitis of left lacrimal passage

This code signifies an acute inflammatory process affecting the lacrimal sac and nasolacrimal duct system on the left side. It typically presents with sudden onset of pain, redness, swelling, and tenderness in the inner corner of the left eye, often accompanied by epiphora and purulent discharge.

Apply this code when documentation clearly indicates an acute infection or inflammation of the left lacrimal drainage system. Supporting documentation should specify the acute nature of the condition and laterality (left side). This code is appropriate for initial presentations or acute exacerbations of dacryocystitis.

• Ensure documentation specifies "acute" and "left" to differentiate from chronic or unspecified dacryocystitis.
• Do not confuse with codes for lacrimal gland disorders (e.g., dacryoadenitis) or other orbital cellulitis.
• Consider an additional code for the causative organism (e.g., bacterial infection) if identified and documented.
