Learn about Cannabinoid Hyperemesis Syndrome (CHS), a condition related to chronic cannabis use. This page provides information on CHS diagnosis, clinical documentation, and medical coding for healthcare professionals. Find details on symptoms, treatment, and ICD-10 codes associated with Cannabis Hyperemesis. Understand the connection between CHS and long-term marijuana use for accurate patient care and documentation.

Follow this step-by-step guide to choose the correct ICD-10 code.
Cyclic vomiting with regular cannabis use?
Yes
Compulsive hot bathing relieves symptoms?
No
Do not code CHS. Code the presenting symptoms or underlying condition.
When to use each related code
| Description |
|---|
| Cyclic vomiting and nausea related to chronic cannabis use. |
| Severe nausea and vomiting unrelated to cannabis. |
| Vomiting from other causes, such as infection or medication. |
Coding CHS without specific symptoms or complications may lead to rejected claims or lower reimbursement. Use specific ICD-10-CM codes when available for accurate coding and documentation.
Misdiagnosis of CHS as cyclic vomiting syndrome can impact patient care and reimbursement. Accurate documentation of cannabis use is crucial for proper diagnosis and coding.
Insufficient documentation of CHS symptoms and their relation to cannabis use can lead to coding errors and compliance issues. Clear documentation supports accurate code assignment and medical necessity reviews.
Q: How to differentiate Cannabinoid Hyperemesis Syndrome (CHS) from cyclic vomiting syndrome and other gastrointestinal disorders in clinical practice?
A: Differentiating Cannabinoid Hyperemesis Syndrome (CHS) from cyclic vomiting syndrome (CVS) and other gastrointestinal disorders requires a thorough patient history, focusing on cannabis use patterns. While both CHS and CVS present with cyclical vomiting and abdominal pain, CHS is characterized by compulsive hot bathing/showering for relief, a symptom not typically seen in CVS. Further, CVS often has a childhood onset, unlike CHS which predominantly affects chronic cannabis users. Consider ruling out other conditions like gastroenteritis, pancreatitis, and bowel obstructions through appropriate diagnostic testing (e.g., complete blood count, metabolic panel, lipase, abdominal imaging). Explore how detailed history taking, including cannabis use frequency, duration, and method of consumption, can help identify CHS in patients presenting with recurrent vomiting. Learn more about the specific diagnostic criteria for CHS to improve accurate diagnosis.
Q: What are the evidence-based best practices for managing Cannabinoid Hyperemesis Syndrome (CHS) patients in the emergency department and outpatient settings?
A: Managing CHS involves both immediate symptomatic relief and long-term behavioral modification. In the emergency department, focus on intravenous fluid resuscitation to address dehydration and electrolyte imbalances. Administering antiemetics, such as ondansetron or haloperidol, can help control nausea and vomiting. Benzodiazepines may be considered for anxiety management. Critically, educate patients on the link between their symptoms and cannabis use. In outpatient settings, reinforce abstinence from cannabis as the cornerstone of CHS treatment. Consider implementing cognitive behavioral therapy (CBT) or motivational interviewing techniques to support cessation. Explore the role of topical capsaicin cream applied to the abdomen, which has shown promise in relieving symptoms. Learn more about developing a comprehensive management plan for CHS that includes both pharmacological and behavioral interventions.
Patient presents with symptoms consistent with Cannabinoid Hyperemesis Syndrome (CHS), also known as Cannabis Hyperemesis. The patient reports cyclical vomiting, nausea, and abdominal pain, specifically noting a history of chronic, regular cannabis use. The patient describes experiencing compulsive hot showering or bathing for relief, a hallmark symptom of CHS. Onset of symptoms began approximately [duration] ago and episodes typically last [duration]. The patient reports temporary relief from hot water immersion. Physical examination reveals [findings, e.g., mild dehydration, epigastric tenderness]. Differential diagnoses considered include cyclic vomiting syndrome, gastroenteritis, and other gastrointestinal disorders. Assessment points towards Cannabinoid Hyperemesis Syndrome based on the patient's history of regular cannabis use, characteristic symptoms of cyclical vomiting and compulsive bathing, and the reported temporary relief with hot water. Treatment plan includes cessation of cannabis use, intravenous hydration for dehydration management, antiemetic medication for nausea and vomiting control, and patient education regarding the connection between cannabis use and CHS. Follow-up appointment scheduled in [timeframe] to monitor symptom resolution and reinforce abstinence from cannabis. ICD-10 code T40.7X1A (poisoning by cannabinoids, accidental or unintentional) and related CPT codes for evaluation and management (e.g., 99203, 99214) are documented for medical billing and coding purposes. Patient counseling on substance abuse cessation provided, focusing on long-term management of CHS. The patient acknowledges understanding of the diagnosis and agrees with the treatment plan.
