Burns: depth, same site, healing and infection

Official text from the FY2027 ICD-10-CM Official Guidelines for Coding and Reporting. The wording is quoted exactly.

Guidelines I.C.19.d

“Burns are classified by depth as first degree (erythema), second degree (blistering), and third degree (full-thickness involvement).”

“Classify burns of the same anatomic site and on the same side but of different degrees to the subcategory identifying the highest degree recorded in the diagnosis”

“Non-healing burns are coded as acute burns.”

“For any documented infected burn site, use an additional code for the infection.”

“When coding burns, assign separate codes for each burn site.”
