Chronic lacrimal mucocele of left lacrimal passage

This code signifies a persistent, non-infectious obstruction of the left lacrimal drainage system, characterized by the accumulation of mucus within the lacrimal sac. This chronic condition typically results in epiphora (excessive tearing) and a palpable, often painless, swelling in the medial canthal region.

Assign this code when documentation clearly indicates a long-standing mucocele affecting the left lacrimal passage. This diagnosis is supported by clinical findings such as chronic epiphora, a distended lacrimal sac on examination, and imaging studies confirming a mucocele without acute infection.

• Ensure documentation specifies "chronic" to differentiate from acute dacryocystitis or other acute lacrimal sac conditions.
• Verify laterality; this code is specific to the left eye.
• Do not use this code for congenital lacrimal sac mucocele (P00-P96 codes).
