O70.1 vs O70.2
O70.1 (Second degree perineal laceration during delivery) compared with O70.2 (Third degree 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. O70.1 carries an Excludes1 note covering O70.2: “perineal laceration involving anal sphincter (O70.2-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
