Epiphora due to excess lacrimation, left lacrimal gland

This diagnosis code signifies an overflow of tears from the left eye, specifically caused by the overproduction of tears by the left lacrimal gland. This condition is distinct from epiphora due to inadequate tear drainage.

Apply this code when documentation clearly indicates excessive tear production from the left lacrimal gland as the etiology of epiphora. This typically involves patient complaints of watery left eye and clinical findings ruling out obstruction of the lacrimal drainage system.

• Ensure laterality is explicitly documented as "left" to support this specific code.
• Differentiate from epiphora due to obstruction of lacrimal passages (H04.22-).
• Code any underlying cause of the excess lacrimation, if known and documented, as a primary diagnosis.
