O99.81 vs R73.0
O99.81 (Abnormal glucose complicating pregnancy, childbirth and the puerperium) compared with R73.0 (Abnormal glucose), 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. R73.0 carries an Excludes1 note covering O99.81: “abnormal glucose in pregnancy (O99.81-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
