O9A.4 (Sexual abuse complicating pregnancy, childbirth and the puerperium) compared with T74.91XS (Unspecified adult maltreatment, confirmed, sequela), 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. T74.91XS carries an Excludes1 note covering O9A.4: “abuse and maltreatment in pregnancy (O9A.3-, O9A.4-, O9A.5-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
