Burn of third degree of unspecified foot, sequela

This code indicates a full-thickness burn injury to an unspecified foot, where the burn has progressed beyond the acute healing phase and is now causing long-term effects or complications. These sequelae can include chronic pain, scarring, contractures, nerve damage, or impaired function directly attributable to the original third-degree burn.

This code is appropriate for documenting a patient presenting with a current condition or complication that is a direct result of a previously sustained third-degree burn to an unspecified foot. It should be used when the initial burn injury has healed, but its lasting impact requires ongoing medical attention or management.

• Always assign an external cause code (V00-Y99) to identify the circumstances of the original burn injury, even for sequela codes.
• Do not use this code for active, acute third-degree burns; instead, use the appropriate acute burn code from the T20-T25 range.
• Consider additional codes for specific sequelae, such as scar contracture (e.g., L90.5) or chronic pain (e.g., G89.29), if documented.
