X00.4XXD — Hit by object from burning building or structure in uncontrolled fire, subsequent encounter
X00.4XXD is a billable, specific ICD-10-CM code for hit by object from burning building or structure in uncontrolled fire, subsequent encounter. It is valid for submission on a claim.

The appropriate 7th character is to be added to each code from category X00
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes2 inherited from the categories above X00.4XXD
Also inherited, and the opposite of Excludes1: these conditions are not part of X00.4XXD, but a patient can have both, so you may code both.
Other codes that can never be billed with X00.4XXD
These codes carry an Excludes1 note pointing at X00.4XXD. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading X00.4XXD 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
Risk adjustment
X00.4XXD 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 history
X00.4XXD has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
