Clinical notes

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

  • acute traumatic of lumbosacral region (S33.1)
  • acute traumatic of sites other than lumbosacral- code to Fracture, vertebra, by region
  • congenital spondylolisthesis (Q76.2)
