Burn first deg mult left fngr (nail), not inc thumb, sequela

This code signifies a healed first-degree burn affecting multiple fingers on the left hand, excluding the thumb, where the burn involved the nail or nail bed. A first-degree burn is superficial, causing redness and pain without blistering, and "sequela" indicates that the acute injury has resolved, and the code is for a residual condition or late effect.

This code is appropriate when documenting a patient presenting with a long-term consequence or late effect of a first-degree burn to multiple left fingers (excluding the thumb) that specifically involved the nail. This might include persistent nail discoloration, altered nail growth, or other chronic issues directly attributable to the original burn. It is used after the initial healing phase of the acute burn.

• Always use an external cause code (V00-Y99) in conjunction with this sequela code to describe the circumstances of the original burn.
• Ensure documentation clearly specifies "multiple left fingers" and explicitly excludes the thumb, as well as indicating nail involvement.
• This code is for a sequela; do not use it for an acute burn. For acute burns, refer to the appropriate T23.13- codes without the "S" seventh character.
