Burn of first degree of unspecified toe(s) (nail), sequela

This code signifies a first-degree burn affecting an unspecified toe or toes, including the nail, where the acute injury has healed and the patient is now presenting for treatment of a residual condition or complication directly related to the original burn. First-degree burns are superficial, involving only the epidermis, and typically present with redness, minor swelling, and pain without blistering.

Use this code when documenting a patient encounter for a long-term effect or complication stemming from a healed first-degree burn to an unspecified toe. This could include chronic pain, scarring, nail deformity, or altered sensation that persists after the initial burn injury has resolved. It is appropriate when the focus of the current encounter is the sequela, not the acute burn.

• Always ensure the "S" seventh character is used for sequela, indicating a late effect of the burn.
• Do not use this code for acute first-degree burns; instead, refer to the appropriate acute burn codes.
• Specify the toe if known, using more precise codes when available (e.g., T25.131S for right great toe).
