Scarring of conjunctiva, bilateral

This code signifies the presence of scar tissue affecting the conjunctiva in both eyes. This scarring can result from various etiologies, including chronic inflammation, trauma, or previous surgical interventions, leading to potential functional impairment of the ocular surface.

Assign this code when documentation clearly indicates bilateral conjunctival scarring. This typically applies to conditions like trachoma sequelae, cicatricial pemphigoid, or chemical burns affecting both conjunctivae. Supporting documentation should specify the bilateral involvement.

• Ensure the medical record explicitly states "bilateral" involvement of conjunctival scarring.
• Do not confuse with unilateral scarring (H11.241, H11.242) or unspecified laterality (H11.249).
• Code any underlying cause of the scarring, such as a specific inflammatory condition or trauma, as an additional diagnosis.
