W18.43XD (Slipping, tripping and stumbling without falling due to stepping from one level to another, subsequent encounter)
compared with
W31 (Contact with other and unspecified machinery),
from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Not coded here — these two are mutually exclusive.
“fall (in) (from) machinery (in operation) (W28-W31)”
An Excludes1 note means the two conditions cannot occur together, so the pair should not be reported for the same encounter. The sole exception is when the conditions are documented as unrelated to each other.
Slipping, tripping and stumbling without falling due to stepping from one level to another, subsequent encounter is a billable ICD-10-CM diagnosis code (W18.43D).
Contact with other and unspecified machinery is a non-billable ICD-10-CM category code (W31).
