Burn of first degree of unspecified ankle, sequela

This code signifies a healed or residual condition resulting from a first-degree burn that previously affected an unspecified ankle. A first-degree burn involves only the epidermis, causing redness and pain without blistering, and the "sequela" indicates that the acute injury has passed, but its long-term effects are being addressed.

Use this code when documenting follow-up care for a patient who previously sustained a first-degree burn to an ankle, and the current encounter is for a residual problem or late effect directly attributable to that burn. This could include persistent discoloration, altered sensation, or scar management after the initial healing phase.

• Always assign a sequela code (S) as a secondary diagnosis, following the code for the current condition being treated.
• Ensure the medical record clearly documents the link between the current issue and the previous first-degree ankle burn.
• Verify that the burn was indeed first-degree and that the specific ankle (right or left) was not documented.
