If a patient suffers multiple burns describe the correct coding sequence?

Correct coding sequence for multiple burns:

Step 1: Identify the most severe burn.

The most severe burn is defined as the burn with the highest Total Burn Surface Area (TBSA) percentage. If there are multiple burns with the same TBSA percentage, the most severe burn is the one that is located on a critical area of the body, such as the face, hands, feet, or genitals.

Step 2: Code the most severe burn.

The most severe burn is coded using the appropriate burn code from Chapter 19 of the ICD-10-CM code book. The burn code is based on the location of the burn and the depth of the burn.

Step 3: Code any additional burns.

If there are any additional burns that are not considered to be the most severe burn, they should be coded using the appropriate burn codes from Chapter 19 of the ICD-10-CM code book. The burn codes for additional burns should be listed in descending order of severity.

Step 4: Add the appropriate external cause code.

An external cause code from Chapter 20 of the ICD-10-CM code book should be added to each burn code. The external cause code indicates the cause of the burn, such as fire, hot liquid, or electrical current.

Example:

A patient suffers from the following burns:

- A 15% TBSA partial-thickness burn to the left arm

- A 10% TBSA full-thickness burn to the right leg

- A 5% TBSA superficial burn to the face

The most severe burn is the 10% TBSA full-thickness burn to the right leg. This burn is coded using the code T23.41XA (Full-thickness burn of right leg, initial encounter for open wound).

The additional burns are coded using the codes T20.31XA (Partial-thickness burn of left arm, initial encounter for open wound) and T14.01XA (Superficial burn of face, initial encounter for open wound).

The external cause code for all of the burns is X94.0 (Accidental contact with hot objects and substances).

The final code sequence is:

- T23.41XA

- T20.31XA

- T14.01XA

- X94.0
