X00 — Exposure to uncontrolled fire in building or structure
X00 is a non-billable header ICD-10-CM code for exposure to uncontrolled fire in building or structure. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category X00
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
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.
Code first
The underlying condition must be sequenced before this code.
- any associated cataclysm
Includes
Conditions this code covers.
- conflagration in building or structure
Other codes that can never be billed with X00
These codes carry an Excludes1 note pointing at X00. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading X00 alone.
- W13.9Fall from, out of or through building, not otherwise specified
- W13.9XXAFall from, out of or through building, not otherwise specified, initial encounter
- W13.9XXDFall from, out of or through building, not otherwise specified, subsequent encounter
- W13.9XXSFall from, out of or through building, not otherwise specified, sequela
- W20.1Struck by object due to collapse of building
- W20.1XXAStruck by object due to collapse of building, initial encounter
- W20.1XXDStruck by object due to collapse of building, subsequent encounter
- W20.1XXSStruck by object due to collapse of building, sequela
Risk adjustment
X00 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead X00
7 child codes. Green means billable.
- X00.0Exposure to flames in uncontrolled fire in building or structure
- X00.1Exposure to smoke in uncontrolled fire in building or structure
- X00.2Injury due to collapse of burning building or structure in uncontrolled fire
- X00.3Fall from burning building or structure in uncontrolled fire
- X00.4Hit by object from burning building or structure in uncontrolled fire
- X00.5Jump from burning building or structure in uncontrolled fire
- X00.8Other exposure to uncontrolled fire in building or structure
Questions about X00
- Is X00 a billable ICD-10-CM code?
- No. X00 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does X00 sit in the tabular list?
- External causes of morbidity (V00-Y99), in the block Exposure to smoke, fire and flames (X00-X08).
