Excludes1 — never code together — inherited from S32

The conditions below can never be reported together with S32.421 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • transection of abdomen (S38.3)

Code first — inherited from S32

The underlying condition below must be sequenced before S32.421. S32.421 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • any associated spinal cord and spinal nerve injury (S34.-)
