W03 vs X08
W03 (Other fall on same level due to collision with another person) compared with X08 (Exposure to other specified smoke, fire and flames), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).
Can these codes be reported together?
Yes, when both are documented. W03 carries an Excludes2 note covering X08: “fall into fire (X00-X04, X08)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
