Burn of second degree of unspecified ankle, sequela

This code indicates a long-term complication or late effect resulting from a second-degree burn that previously affected an unspecified ankle. A second-degree burn involves damage to the epidermis and dermis, characterized by blistering, pain, and redness. The "sequela" designation signifies that the burn itself is no longer acute, but its lasting effects are being treated.

Use this code when documenting conditions such as chronic scarring, contractures, persistent pain, or nerve damage that are directly attributable to a past second-degree burn of the ankle. This applies when the original burn has healed, and the current encounter addresses these residual issues.

• Always use an external cause code (V00-Y99) in conjunction with sequela codes to describe the original cause of the burn, if known.
• Ensure documentation clearly links the current ankle condition to a previous second-degree burn.
• The "S" in the seventh character indicates sequela, meaning the acute phase of the injury has passed.
