Excludes1 — never code together

The conditions below can never be reported together with Z36 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 examination- code to sign or symptom
encounter for suspected maternal and fetal conditions ruled out (Z03.7-)
suspected fetal condition affecting management of pregnancy - code to condition in Chapter 15

Excludes2 — not included here

The conditions below are not part of Z36, but a patient may have both at the same time. When documentation supports it, Z36 and the excluded code may both be reported.
