Z03.7Encounter for suspected maternal and fetal conditions ruled out

Z03.7 is the ICD-10-CM diagnosis code for encounter for suspected maternal and fetal conditions ruled out. It belongs to category Z03 (encounter for medical observation for suspected diseases and conditions ruled out), block Z00-Z13 (persons encountering health services for examinations) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within Z03 (encounter for medical observation for suspected diseases and conditions ruled out), Z03.7 is specifically for encounter for suspected maternal and fetal conditions ruled out. Related codes cover observation for suspected toxic effect from ingested substance ruled out (Z03.6) and observation for other suspected diseases and conditions ruled out (Z03.8).

To report this condition, pick the subcode that matches the documentation: Z03.71 (out), Z03.72 (out), Z03.73 (out), Z03.74 (out), Z03.75 (out) and Z03.79 (out).

Don't report Z03.7 together with the conditions in its Excludes1 note: known or suspected fetal anomalies affecting management of mother, not ruled out (O26.-, O35.-, O36.-, O40.-, O41.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
