Excludes1 — never code together
The conditions below can never be reported together with Z31.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- postvasectomy sperm count (Z30.8)
Excludes2 — not included here — inherited from Z31
The conditions below are not part of Z31.4, but a patient may have both at the same time. When documentation supports it, Z31.4 and the excluded code may both be reported.
