X05 — Exposure to ignition or melting of nightwear
X05 is a non-billable header ICD-10-CM code for exposure to ignition or melting of nightwear. 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 code X05
- 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.
- exposure to uncontrolled fire in building or structure (X00.-)
- exposure to uncontrolled fire, not in building or structure (X01.-)
- exposure to controlled fire in building or structure (X02.-)
- exposure to controlled fire, not in building or structure (X03.-)
- exposure to ignition of highly flammable materials (X04.-)
Risk adjustment
X05 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.
How X05 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to X05.
