Cannabis Hyperemesis Syndrome
Learn about Cannabis Hyperemesis Syndrome (CHS), a condition characterized by cyclical vomiting and abdominal pain associated with chronic cannabis use. This page provides information on CHS diagnosis, clinical documentation, and medical coding for healthcare professionals. Find resources on cannabinoid hyperemesis syndrome symptoms, treatment, and ICD-10 codes relevant to CHS for accurate medical billing and reporting. Understand the connection between chronic cannabis use and CHS to improve patient care and documentation.
A cyclic vomiting syndrome associated with chronic, heavy cannabis use.
Severe nausea, vomiting, abdominal pain, and compulsive hot bathing for relief.
Emergency departments, urgent care clinics, and gastroenterology offices.
ICD-10 Code Families
Complete code families applicable to F12.221
When to use each related code
| Description | When to use |
|---|---|
| Recurring nausea and vomiting related to chronic cannabis use. | Code C when cyclical vomiting, abdominal pain, and compulsive hot bathing are present in a chronic cannabis user. |
| Recurring episodes of severe nausea and vomiting unrelated to cannabis. | Code Cyclical Vomiting Syndrome when chronic cannabis use is not implicated and other causes are ruled out. Consider if symptoms improve with hot bathing. |
| Nausea and vomiting due to another identifiable cause. | Code the underlying cause of nausea and vomiting, e.g., gastroenteritis, chemotherapy-induced nausea, etc., not CHS. |
Best-practice checklist
- ✓Document cyclical vomiting episodes.
- ✓Confirm chronic cannabis use.
- ✓Note compulsive hot bathing behavior.
- ✓Symptom resolution with cannabis cessation.
- ✓Rule out other GI diagnoses (e.g., cyclic vomiting syndrome).
Common pitfalls to avoid
Symptoms mimic cyclic vomiting syndrome, leading to misdiagnosis and incorrect coding (R11.10, R11.11 vs. T40.7X5A).
Using unspecified nausea/vomiting codes (R11.0, R11.10, R11.2) when CHS is suspected delays proper diagnosis and treatment.
Insufficient documentation of cannabis use and characteristic symptoms hinders accurate coding and compliance audits (Z72.0).
Best-practice tips
- 01Discontinue cannabis use immediately. Document cessation thoroughly.
- 02Hydration with IV fluids, monitor electrolytes for imbalances (ICD-10-CM: T40.7X1A).
- 03Antiemetic therapy, consider capsaicin cream for symptom relief (CPT: 9928X).
- 04Educate patients on CHS, emphasize complete abstinence for recovery.
- 05Regular follow-up to assess symptom resolution and prevent relapse. Document in medical record.

Ready-to-paste narrative
Patient presents with symptoms consistent with Cannabis Hyperemesis Syndrome (CHS), also known as Cannabinoid Hyperemesis Syndrome. The patient reports cyclical vomiting, nausea, and abdominal pain, specifically noting a history of chronic, heavy cannabis use. The patient describes experiencing temporary relief of symptoms with hot bathing or showering, a hallmark sign of CHS. On physical examination, the patient appears dehydrated with mild epigastric tenderness. Differential diagnoses considered include cyclic vomiting syndrome, gastroenteritis, and other causes of abdominal pain and vomiting. Laboratory tests, including a complete blood count (CBC) and comprehensive metabolic panel (CMP), were ordered to rule out other medical conditions and assess hydration status. Diagnosis of Cannabis Hyperemesis Syndrome is based on the patient's history of regular cannabis use, characteristic symptoms of cyclical vomiting and nausea, compulsive hot bathing behavior, and the absence of other identifiable causes. The patient was advised to cease cannabis use. Treatment plan includes intravenous fluid hydration for dehydration management and antiemetic medication to control nausea and vomiting. Patient education was provided on the association between cannabis use and CHS, emphasizing the importance of cessation for symptom resolution. Follow-up appointment scheduled to monitor symptom improvement and provide further support for cannabis cessation. ICD-10 code T40.7X1A (poisoning by cannabinoids, accidental unintentional) and related billing codes will be applied for documentation and reimbursement purposes.
Common questions and answers
How to differentiate Cannabis Hyperemesis Syndrome (CHS) from other cyclical vomiting syndromes in a clinical setting?+
Differentiating Cannabis Hyperemesis Syndrome (CHS) from other cyclical vomiting syndromes like cyclic vomiting syndrome (CVS) and abdominal migraine can be challenging due to overlapping symptoms. Key differentiators for CHS include a history of chronic cannabis use, characteristic prodromal phase of nausea and abdominal pain, compulsive hot bathing behavior that relieves symptoms, and resolution of symptoms with cannabis cessation. Consider incorporating a detailed substance use history, assessment of bathing habits for symptom relief, and evaluating the patient's response to a trial of cannabis abstinence into your diagnostic workup. Explore how detailed patient history and targeted physical exam findings can aid in accurate CHS diagnosis and improve patient outcomes. While laboratory and imaging studies may be used to rule out other conditions, they are not typically diagnostic for CHS. Learn more about the diagnostic criteria for CHS and the importance of ruling out other potential causes of cyclical vomiting.
What are the most effective management strategies for patients presenting with Cannabis Hyperemesis Syndrome (CHS) in the emergency department?+
Managing acute episodes of Cannabis Hyperemesis Syndrome (CHS) in the emergency department typically involves supportive care focused on symptom relief. This includes intravenous fluid rehydration to address dehydration and electrolyte imbalances, antiemetics such as ondansetron or haloperidol for nausea and vomiting, and anxiolytics like benzodiazepines to manage anxiety and agitation. While hot bathing behavior may provide temporary relief for patients, it's important to discourage this practice due to the risk of burns and dehydration. Consider implementing a patient education strategy that emphasizes the link between cannabis use and CHS symptoms and encourages cessation. Learn more about the long-term management of CHS and the role of behavioral therapies in supporting cannabis abstinence. Explore how integrating substance abuse counseling and support services can improve patient outcomes in the long term.
What are the long-term complications and prognosis of Cannabis Hyperemesis Syndrome (CHS) if cannabis use continues?+
If cannabis use continues, patients with Cannabis Hyperemesis Syndrome (CHS) can experience recurrent and increasingly severe episodes of cyclical vomiting, leading to significant disruptions in their daily lives. Long-term complications can include electrolyte imbalances, malnutrition due to persistent vomiting, and psychological distress related to the unpredictable nature of the symptoms. Furthermore, continued cannabis use can exacerbate underlying psychological conditions and increase the risk of developing cannabinoid dependence. Consider implementing a comprehensive treatment plan that addresses both the physical symptoms and the underlying substance use disorder. Learn more about the effectiveness of harm reduction strategies and motivational interviewing techniques in promoting cannabis cessation. Explore how integrated treatment approaches can improve the prognosis for patients with CHS and minimize the risk of long-term complications.
