Vomiting of pregnancy, unspecified

This code signifies the presence of emesis during gestation without further specification of its severity or underlying cause. It represents a common symptom experienced by pregnant individuals, ranging from mild morning sickness to more persistent nausea and vomiting.

This code is appropriate when documentation indicates vomiting related to pregnancy but lacks specific details to classify it as hyperemesis gravidarum or other specified forms. It is used when the physician's notes simply state "vomiting in pregnancy" or "nausea and vomiting of pregnancy" without further elaboration on severity, dehydration, or metabolic disturbances.

• Avoid using this code if documentation supports hyperemesis gravidarum (O21.0-O21.2) or other specified vomiting conditions.
• Always review the medical record for any mention of dehydration, weight loss, or electrolyte imbalance, which would necessitate a more specific code.
• This code should be sequenced as a primary diagnosis when the vomiting is the primary reason for the encounter, or as a secondary diagnosis if it's a co-morbidity.
