O72.3 vs O99.1
O72.3 (Postpartum coagulation defects) compared with O99.1 (Other diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism complicating pregnancy, childbirth and the puerperium), 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. O99.1 carries an Excludes1 note covering O72.3: “hemorrhage with coagulation defects (O45.-, O46.0-, O67.0, O72.3)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
