Excludes1 — never code together — inherited from R40
The conditions below can never be reported together with R40.23 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first — inherited from R40.2
The underlying condition below must be sequenced before R40.23. R40.23 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R40.23, but a patient may have both at the same time. When documentation supports it, R40.23 and the excluded code may both be reported.
Excludes2 — not included here — inherited from R40-R46
The conditions below are not part of R40.23, but a patient may have both at the same time. When documentation supports it, R40.23 and the excluded code may both be reported.
