X00.4 — Hit by object from burning building or structure in uncontrolled fire
X00.4 is a non-billable header ICD-10-CM code for hit by object from burning building or structure in uncontrolled fire. 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.

Risk adjustment
X00.4 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 X00.4 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 X00.4.
