O30-O48: Maternal care related to the fetus and amniotic cavity and possible delivery problems

O33: Maternal care for known or suspected disproportion

Maternal care for known or suspected disproportion, as classified under the ICD-10 code range O33, refers to a group of conditions that arise during pregnancy where there is a mismatch between the size of the mother's pelvis and the size of the baby. This can be due to a small or abnormally shaped pelvis in the mother, or a larger than normal baby. These conditions are not transmitted, but arise naturally due to biological factors and can sometimes be linked to the mother's health or the baby's growth. Typical symptoms can include prolonged labor, intense pain, or the baby not moving down into the birth canal as expected. The progress of these conditions is usually monitored closely by healthcare professionals to ensure the safety of both mother and baby. If not well managed, they can affect the process of childbirth and may potentially lead to complications.
