Other vomiting complicating pregnancy

This code represents instances of vomiting during pregnancy that are more severe than typical morning sickness but do not meet the criteria for hyperemesis gravidarum. It encompasses various forms of nausea and vomiting in pregnancy that require medical attention or intervention, but are not life-threatening or associated with significant weight loss or electrolyte imbalance.

Use this code when documentation indicates vomiting in pregnancy that is problematic for the patient, such as persistent nausea and vomiting requiring antiemetics, intravenous fluids, or other medical management, but without the severe dehydration, ketonuria, or significant weight loss characteristic of hyperemesis. Documentation should specify "vomiting complicating pregnancy" or similar phrasing, and rule out hyperemesis.

• Differentiate carefully from hyperemesis gravidarum (O21.0-O21.2), which involves severe, intractable vomiting with metabolic disturbances.
• Ensure documentation clearly states the vomiting is "complicating pregnancy" and not just a normal physiological symptom.
• Consider additional codes for any associated conditions or complications, such as dehydration (E86.0) if present but not severe enough for hyperemesis.
