A3 year-old is brought to the burn unit after pulling a pot of hot soup off the stove and spilling it on herself. she sustained 18% second degree burns on her legs and 20% third degree burns on her chest and arms. total body surface area burned is 38%. what icd-10-cm codes are reported for the burns (do not include external cause codes for the accident)?

T21.31XA, T22.399A, T24.299A, T31.32

Explanation:

The guideline I.C.19.d.1 of ICD-10-CM code says that the when there are more than one burn in body, the burn of highest degree must be kept at first position in any sequence.  

Here the burning on chest and arm is of third degree , thus it must be at first position and signified by subcategory T21.31. Also there are burns on arms and legs , therefore these must be quoted as  

Burn on upper limb/multiple sites - T22.399

Burn on upper limb/multiple sites - T24.299

The code of percentage degree of burn is T31.32 which signifies 30-39 % body surface burn and 20-29 percent third degree burns

Also A denote the initial encounter and X signifies a place holder.

Thus the correct code will be  

T21.31XA, T22.399A, T24.299A, T31.32

it has one origin of replication, but it proceeds in two directions - d)
