N90 vs O70
N90 (Other noninflammatory disorders of vulva and perineum) compared with O70 (Perineal laceration during delivery), 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. N90 carries an Excludes1 note covering O70: “current obstetric trauma (O70.-, O71.7-O71.8)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
