Cyclical vomiting, in migraine, not intractable

This code describes cyclical vomiting that occurs as a manifestation of migraine, where the vomiting episodes are not severe enough to be considered intractable. Patients experience recurrent, stereotypical episodes of intense nausea and vomiting, often accompanied by other migraine symptoms, with symptom-free intervals between episodes. This condition is distinct from other causes of recurrent vomiting.

Assign this code when documentation clearly links cyclical vomiting to a migraine diagnosis and specifies that the condition is not intractable. This is appropriate for patients experiencing episodic, severe vomiting associated with migraine, where standard treatments are generally effective in managing the episodes. Documentation should differentiate this from intractable migraine or other forms of cyclical vomiting.

• Ensure documentation explicitly states "in migraine" and "not intractable" to support this specific code.
• Do not use this code if the cyclical vomiting is due to another underlying condition or if the migraine itself is documented as intractable.
• Consider sequencing this code after the primary migraine code if the cyclical vomiting is a symptom or manifestation of the migraine.
