Excludes1 — never code together — inherited from K57
The conditions below can never be reported together with K57.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 11
