Excludes1 — never code together — inherited from S61

The conditions below can never be reported together with S61.300A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • open fracture of wrist, hand and finger (S62.- with 7th character B)
  • traumatic amputation of wrist and hand (S68.-)
