Burn of first degree of unspecified upper arm, sequela

This code signifies a first-degree burn affecting an unspecified area of the upper arm, where the burn itself is no longer an active injury but rather a long-term consequence or complication of the original burn. First-degree burns are superficial, involving only the outermost layer of skin, typically presenting with redness and mild pain without blistering.

Apply this code when documenting a patient encounter for a residual effect or late complication directly attributable to a resolved first-degree burn of the upper arm. This is appropriate for follow-up care concerning scarring, pigment changes, or other persistent issues after the initial burn has healed.

• Ensure the "S" seventh character is appended only for sequelae, meaning the acute phase of the burn has passed.
• Confirm the burn was indeed first-degree and located on the upper arm; avoid using for other burn depths or locations.
• Always code the specific sequela (e.g., scar, pain) first, followed by this code to indicate the cause.
