O08.3 vs R57
O08.3 (Shock following ectopic and molar pregnancy) compared with R57 (Shock, 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. R57 carries an Excludes1 note covering O08.3: “shock complicating or following ectopic or molar pregnancy (O00-O07, O08.3)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
