Burn of first degree of trunk, unspecified site, sequela

This code signifies a healed or residual effect from a first-degree burn that previously affected the trunk. A first-degree burn involves only the epidermis, causing redness and pain without blistering, and the "sequela" indicates that the acute injury has resolved, but a lasting consequence or condition related to the burn is being addressed.

Use this code when documenting a patient encounter where a long-term effect or complication stemming from a past first-degree burn of the trunk is the focus of care. This could include persistent skin discoloration, altered sensation, or other chronic issues directly attributable to the prior burn. Do not use this code for the initial treatment of an acute burn.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the burn injury, even for sequela codes.
• Ensure documentation clearly links the current condition to the previous first-degree burn of the trunk.
• If the specific site on the trunk is known, a more specific code should be used instead of "unspecified site."
