Excludes1 — never code together — inherited from R05
The conditions below can never be reported together with R05.3 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 18
The conditions below are not part of R05.3, but a patient may have both at the same time. When documentation supports it, R05.3 and the excluded code may both be reported.
