Z13.7 vs Z31.4
Z13.7 (Encounter for screening for genetic and chromosomal anomalies) compared with Z31.4 (Encounter for procreative investigation and testing), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Z13.7 carries an Excludes1 note covering Z31.4: “genetic testing for procreative management (Z31.4-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
