Excludes1 — never code together
The conditions below can never be reported together with R19 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- acute abdomen (R10.0)
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R19, but a patient may have both at the same time. When documentation supports it, R19 and the excluded code may both be reported.
