Burn of second degree of trunk, unspecified site, sequela

This code signifies a second-degree burn affecting the trunk, where the specific location on the trunk is not documented. Second-degree burns are characterized by blistering, pain, and damage to both the epidermis and dermis. The "sequela" seventh character indicates that this encounter is for complications or conditions arising directly from a previous burn injury, not the initial treatment of the acute burn.

This code is appropriate when a patient presents for follow-up care, scar revision, or management of chronic pain directly attributable to a second-degree burn of the trunk that occurred in the past. It is used when the original burn site on the trunk (e.g., chest, back, abdomen) was not specified in the initial documentation or is no longer relevant to the current sequela.

• Always ensure documentation clearly states the encounter is for sequelae of a burn, not an acute injury.
• Verify that the burn is indeed second-degree and located on the trunk, with no more specific site identified.
• Do not use this code for initial treatment of an acute burn; instead, use the appropriate acute burn code with the initial encounter seventh character.
