X00-X08Exposure to smoke, fire and flames

ICD-10-CM codes X00-X08 cover exposure to smoke, fire and flames, within external causes of morbidity. The block holds 169 codes across 8 categories, of which 120 are billable and 49 are header codes that cannot be submitted on a claim. 169 of them (100%) require a 7th character.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

The 7th character in X00-X08

A code in this block is not complete without its 7th character, and a missing one is a rejected claim rather than a denied one: the clearinghouse never passes it on. 169 of the 169 codes here take one.

A
initial encounter
D
subsequent encounter
S
sequela
