In the burn patient case, which external cause code is listed?

• A. X12.XXXB
• B. X12.XXXC
• C. X12.XXXD
• D. X12.XXXA

Answer: (D)

External cause codes show how an injury happened and under what circumstances, including the mechanism (such as exposure to heat) and the encounter status. In ICD-10-CM, these codes in the X12 family describe exposure to heat or fire, with the final character indicating the encounter type: A for the initial encounter, D for a subsequent encounter, and S for a sequela. For a burn patient’s current presentation, you want the code that reflects the initial treatment encounter, so it ends with A. Codes ending in B, C, or D would indicate subsequent encounters or other statuses and aren’t appropriate for the present visit. Therefore, the correct external cause code is X12.XXXA.
