O9A vs T86

O9A (Maternal malignant neoplasms, traumatic injuries and abuse classifiable elsewhere but complicating pregnancy, childbirth and the puerperium) compared with T86 (Complications of transplanted organs and tissue), from the official CMS tabular data. Both may be reported when both conditions are documented (Excludes2).

Can these codes be reported together?

Yes, when both are documented. T86 carries an Excludes2 note covering O9A: “complications of surgical procedures during pregnancy, childbirth and the puerperium (O00-O9A)”

Excludes2 marks distinct conditions — both may be reported when both are documented.
