Excludes1 — never code together — inherited from Q50-Q56
The conditions below can never be reported together with Q50.5 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 17
The conditions below are not part of Q50.5, but a patient may have both at the same time. When documentation supports it, Q50.5 and the excluded code may both be reported.
