Health Problems in Pregnancy

A health problem in pregnancy is any disease or condition that could affect your health or the health of your fetus. Some health problems may make it more likely that you will have a high-risk pregnancy. A high-risk pregnancy is one in which you, your fetus, or both are at higher risk for health problems than in a typical pregnancy.

The full article covers:

  • What are health problems in pregnancy?
  • What raises my risk for health problems during pregnancy?
  • Can chronic health conditions cause problems in pregnancy?
  • Can health problems in pregnancy be prevented?

Questions About O22Overview

What is the ICD-10 code for venous complications and hemorrhoids in pregnancy?

O22 is the ICD-10-CM category for venous complications and hemorrhoids in pregnancy, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is O22 (Venous complications and hemorrhoids in pregnancy) a billable code?

No. This is a category header that groups the codes for venous complications and hemorrhoids in pregnancy, and headers cannot be submitted on claims. Claims for venous complications and hemorrhoids in pregnancy need a more specific code from this category, such as O22.00, O22.01, and O22.02.

Can O22 be reported with O03.9?

Not as a rule. The Excludes1 note on O22 lists "abortion NOS (O03.9)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
