Sequelae of trachoma

This code identifies the long-term, residual effects or complications resulting from a past trachoma infection. These sequelae can include chronic conjunctivitis, corneal scarring, trichiasis (in-turned eyelashes), entropion (in-turned eyelid), and ultimately, vision impairment or blindness. It indicates that the active trachoma infection has resolved, but its lasting damage persists.

Use this code when a patient presents with chronic ocular conditions directly attributable to a previously diagnosed and treated, or resolved, trachoma infection. Documentation should clearly link the current eye condition to a history of trachoma, often noting findings like corneal opacities or eyelid deformities characteristic of trachoma sequelae.

• Always sequence this code after the code for the specific sequela (e.g., H11.21- for corneal opacity, H02.0- for entropion).
• Do not use this code if the trachoma infection is still active; instead, use codes from category A71.
• Ensure the medical record explicitly states a history of trachoma and describes the resulting chronic eye condition.
