W03.XXXD vs W18.30
W03.XXXD (Other fall on same level due to collision with another person, subsequent encounter) compared with W18.30 (Fall on same level, unspecified), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. W03.XXXD carries an Excludes1 note covering W18.30: “fall on same level NOS (W18.30)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
