Initial stage of trachoma

This code signifies the very first phase of trachoma, a chronic infectious eye disease caused by Chlamydia trachomatis. It is characterized by conjunctival inflammation, specifically follicular conjunctivitis, before the development of scarring or other more severe sequelae.

Apply this code when documentation clearly indicates the presence of active trachomatous inflammation, follicular (TF), without signs of conjunctival scarring (TS) or trichiasis (TT). This typically applies to early presentations identified during screening programs or initial clinical examination.

• Ensure documentation specifies "follicular" inflammation and explicitly states the absence of scarring or other advanced signs.
• Do not use this code if any degree of conjunctival scarring is noted; instead, refer to codes for later stages of trachoma.
• Consider co-reporting with codes for Chlamydia trachomatis infection if laboratory confirmation is available and clinically relevant.
