O20-O29: Other maternal disorders predominantly related to pregnancy

The ICD-10 group range O20-O29 pertains to maternal disorders predominantly related to pregnancy. These disorders are specific health conditions that a woman might experience during her pregnancy period and that are not fundamentally linked to the growing fetus. They could be existing health problems that become complicated due to pregnancy, or new issues that develop as a result of the pregnancy itself. Symptoms and disease progression vary widely depending on the specific disorder, but can often include discomfort, pain, bleeding, or unusual discharge. These issues might affect various body systems, from cardiovascular and respiratory to digestive and endocrine systems. Causes can be as diverse as the conditions themselves, from physiological changes that happen during pregnancy, pre-existing chronic diseases that worsen due to pregnancy, to pregnancy-induced complications. All these disorders could potentially influence the course and outcome of the pregnancy. These conditions do not get transmitted as they are not infectious diseases.
