Excludes1 — never code together
The conditions below can never be reported together with R03.1 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 R03.1, but a patient may have both at the same time. When documentation supports it, R03.1 and the excluded code may both be reported.
How long has R03.1 existed?
R03.1 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
