About O70

O70 is the ICD-10-CM diagnosis code for perineal laceration during delivery. It belongs to block O60-O77 (complications of labor and delivery) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: O70.0 (delivery), O70.1 (delivery), O70.2 (delivery), O70.3 (delivery), O70.4 (laceration) and O70.9 (unspecified).

Don't report O70 together with the conditions in its Excludes1 note: obstetric high vaginal laceration alone (O71.4).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
