Excessive vomiting in pregnancy.
Medical necessity for treatment is established by the severity of the symptoms and their impact on the patient's health.In cases of mild nausea and vomiting, conservative management is sufficient.For moderate to severe cases, medical intervention becomes necessary to address dehydration, nutritional deficiencies, and potential complications.
The clinical responsibility for managing excessive vomiting in pregnancy falls upon obstetricians or other healthcare professionals providing prenatal care.This includes assessing the severity of the condition, managing symptoms, and providing nutritional support.In severe cases, hospitalization and intravenous fluid therapy might be necessary.

- O20-O29 (Other maternal disorders predominantly related to pregnancy)
In simple words: This code is used when a pregnant woman experiences excessive vomiting.This can range from mild nausea to severe sickness that affects her health.
This ICD-10-CM code classifies excessive vomiting during pregnancy.It encompasses a range of severity, from mild nausea and vomiting to severe hyperemesis gravidarum, which can lead to significant dehydration, electrolyte imbalances, and nutritional deficiencies.The diagnosis requires careful assessment of the patient's symptoms, including frequency, intensity, duration, and impact on overall health.Further specification may be necessary depending on the presence of metabolic disturbances (O21.1).
Example 1: A 28-year-old woman at 8 weeks gestation presents with persistent nausea and vomiting for the past week, resulting in mild dehydration., A 35-year-old woman at 12 weeks gestation has severe hyperemesis gravidarum, leading to significant weight loss, dehydration, and electrolyte imbalances, requiring hospitalization and IV fluids., A 25-year-old woman at 6 weeks gestation experiences moderate nausea and vomiting that interferes with her daily life but does not cause significant dehydration or weight loss.
Detailed documentation should include the onset, frequency, intensity, and duration of vomiting.Weight changes, electrolyte levels (if tested), hydration status, and any interventions or treatments should also be recorded.Include any impact on the patient's daily activities and overall well-being.
** This code should only be used on the maternal record and never on the newborn record.The code should be used for conditions related to or aggravated by pregnancy, childbirth, or the puerperium.
