O22.4Hemorrhoids in pregnancy

O22.4 is the ICD-10-CM diagnosis code for hemorrhoids in pregnancy. It belongs to category O22 (venous complications and hemorrhoids in pregnancy), 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 4 subcodes must be used instead.

Within O22 (venous complications and hemorrhoids in pregnancy), O22.4 is specifically for hemorrhoids in pregnancy. Related codes cover varicose veins of lower extremity in pregnancy (O22.0), genital varices in pregnancy (O22.1), superficial thrombophlebitis in pregnancy (O22.2), deep phlebothrombosis in pregnancy (O22.3), cerebral venous thrombosis in pregnancy (O22.5), other venous complications in pregnancy (O22.8) and venous complication in pregnancy, unspecified (O22.9).

To report this condition, pick the subcode that matches the documentation: O22.40 (unspecified trimester), O22.41 (first trimester), O22.42 (second trimester) and O22.43 (third trimester).

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