About O74
O74 is the ICD-10-CM diagnosis code for complications of anesthesia during labor and 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: O74.0 (delivery), O74.1 (delivery), O74.2 (delivery), O74.3 (delivery), O74.4 (delivery), O74.5 (delivery), O74.6 (delivery), O74.7 (delivery) and 2 more.
Use an additional code, if applicable, to identify specific complication.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
