O90.1 vs T81.3
O90.1 (Disruption of perineal obstetric wound) compared with T81.3 (Disruption of wound, not elsewhere classified), 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. T81.3 carries an Excludes1 note covering O90.1: “disruption of perineal obstetric wound (O90.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
