The conditions below can never be reported together with R88 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

- diagnostic abnormal findings classified elsewhere - see Alphabetical Index
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R88, but a patient may have both at the same time. When documentation supports it, R88 and the excluded code may both be reported.
