Can these codes be reported together?
No — do not report together. R86 carries an Excludes1 note covering O28: “abnormal findings on antenatal screening of mother (O28.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
