About O22
O22 is the ICD-10-CM diagnosis code for venous complications and hemorrhoids in pregnancy. It belongs to block O20-O29 (other maternal disorders predominantly related to pregnancy) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: O22.0 (pregnancy), O22.1 (pregnancy), O22.2 (pregnancy), O22.3 (pregnancy), O22.4 (pregnancy), O22.5 (pregnancy), O22.8 (pregnancy) and O22.9 (unspecified).
Don't report O22 together with the conditions in its Excludes1 note: abortion NOS (O03.9), ectopic or molar pregnancy (O08.7), failed attempted abortion (O07.35), induced abortion (O04.85) and 1 more.
The conditions in its Excludes2 note aren't part of O22, but may be coded alongside it if the patient has both: obstetric pulmonary embolism (O88.-) and venous complications and hemorrhoids of childbirth and the puerperium (O87.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
