In simple words: A mild burn affecting an area of the torso, excluding specific regions like the chest, abdomen, back, buttocks, or genitals.

First-degree burn involving areas of the trunk other than the chest wall, abdominal wall, upper back, lower back, buttock, male genital region, or female genital region. This excludes burns of the axilla (T22.-) and requires an additional external cause code (X00-X19, X75-X77, X96-X98, Y92).

Example 1: A patient presents with mild sunburn across the flank, diagnosed as a first-degree burn., A patient accidentally splashes hot coffee on their side, resulting in a first-degree burn., A patient sustains a first-degree burn on their hip area due to prolonged contact with a heating pad.

Detailed description of the burn's location, size, and depth. Documentation of associated symptoms, such as pain, redness, or swelling. The cause and circumstances of the burn should also be recorded.

** Distinguishing "other site of trunk" is crucial. Ensure appropriate documentation to support medical necessity for treatment.Always include an external cause code describing the origin of the burn (e.g., contact with hot object, scald).
