Cyclical vomiting syndrome unrelated to migraine
ICD-10 R11.15 is a billable code used to indicate a diagnosis of cyclical vomiting syndrome unrelated to migraine.
Cyclical vomiting syndrome (CVS) is characterized by recurrent episodes of severe vomiting that can last for hours to days, with symptom-free intervals in between. Unlike migraine-associated vomiting, CVS is not linked to headache or other migraine symptoms. Patients often present with nausea, vomiting, abdominal pain, and dehydration during episodes. The etiology of CVS is not fully understood, but it may involve autonomic nervous system dysfunction, gastrointestinal motility disorders, or psychological factors. Laboratory findings may show electrolyte imbalances due to vomiting, but no specific tests confirm CVS. Diagnosis is primarily clinical, based on the pattern of symptoms and exclusion of other causes of vomiting. It is essential to document the frequency, duration, and severity of episodes, as well as any associated symptoms, to support the diagnosis and coding accurately.
Detailed history of vomiting episodes, including triggers, duration, and associated symptoms.
Patients presenting with recurrent vomiting without headache, often requiring hydration and electrolyte management.
Consider psychological evaluations if stress or anxiety is suspected as a trigger.
Acute care notes should include vital signs, hydration status, and immediate interventions.
Patients presenting to the ED with severe vomiting, dehydration, and potential electrolyte imbalances.
Rapid assessment and treatment are crucial; ensure documentation reflects the urgency of care.
Used for follow-up visits to manage CVS symptoms.
Document history of present illness, review of systems, and management plan.
Internal medicine may focus on chronic management, while emergency medicine may focus on acute care.
The primary difference is that CVS occurs without the presence of headache or other migraine symptoms, making it a distinct clinical entity.
