Excludes1 — never code together — inherited from W00-W19

The conditions below can never be reported together with W18.09XA on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • assault involving a fall (Y01-Y02)
  • fall from animal (V80.-)
  • fall (in) (from) machinery (in operation) (W28-W31)
  • fall (in) (from) transport vehicle (V01-V99)
  • intentional self-harm involving a fall (X80-X81)

Excludes1 — never code together — inherited from W18.0

The conditions below can never be reported together with W18.09XA on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
