Patients should follow the instructions for use in their kit for additional test instructions and updated return shipping information. Patients can also contact CDI’s dedicated customer service team at 888-258-5966 or customerservice@commdx.com with questions or concerns.
Our hydrogen and methane breath test kits are available to health care providers at no cost. Orders may be placed through our website’s Ordering page or by submitting the pdf order form via email or fax. Test kits can be shipped directly to your patients’ homes or to your office. Contact our Provider Services Department at 978-233-4601 or providerservices@commdx.com for more information.
Our patient-centric model allows your patients to administer these tests in the comfort of their own home. Your office will simply fill out the one-page Requisition Form included in every kit and send your patient home to take it. A pre-paid return shipping label is included in the kit for easy patient return to our laboratory. We will take care of the rest.
We provide a pre-paid, pre-addressed shipping label in each kit. Patients will simply take the completed test kit, seal it with the provided label, and return it to us using the shipping carrier listed on the label.
When the kit arrives at our laboratory, it will be analyzed within 1 business day. Results are reported within 1-2 business days, barring any missing information. Kits that arrive on Saturdays or holidays will be analyzed the following business day. Results will be sent to your practice via a secure fax system, secure email, or your office can set up an account with us to receive results via our HIPAA-compliant web portal, MyGI Gateway.
Insurance may cover some or all of your patient’s breath test depending on the patient’s insurance plan and benefits. Please direct your patients to contact their insurance carrier(s) ahead of time with CDI’s billing information in order to determine potential coverage and out-of-pocket cost. We bill the medical insurance provider specified by patients on their Requisition Form included in each kit after kits are returned for processing. CDI does not accept Medicaid, any Medicaid patient who returns a completed test will be responsible for the out-of-pocket cost. We offer a patient assistance program for qualified individuals who cannot afford the test. Additional information is available here: Insurance & Billing Policies.
This depends on the patient’s individual health plan. Even within the same medical health insurance company, some plans require pre-authorization and others do not. It is best for the patient to contact the appropriate health insurance representative to inquire about pre-authorization. Your patients’ claim may require an out-of-network pre-authorization referral. If an authorization is required, your office will be the party responsible for necessary documentation to prove medical necessity as required by the insurance carrier.
If a pre-authorization is obtained, please ask the patient to write the authorization number on the Requisition Form they will be sending to us with the breath samples and forward a copy of the document(s).
If your patient has no medical insurance, ask him or her to call our office for information. We do have cash pay options available, and we work with patients individually on a case-by-case basis to determine appropriate payment options. Dial 1-888-258-5966 to reach our Customer Service Department.
CDI may not know that a test is invalid until it is fully processed by the lab. Patients may still be billed for the test if the test is invalid due to patient error. For more information on Invalid reports, view the page here: Invalid Test Results.
Additional information is listed on the result report rider provided with these reports that explains why the overall determination is Invalid, as well as to determine if you may use the result data to form an interpretation or if retesting is recommend.
CDI will bill patients when the result is an “Invalid” (invalid baseline, incorrect collection interval, etc.), “Rejected” (incorrect sample type, non-CDI components, etc.), or “Expired”. However, CDI also offers patients a complimentary second test, if the patient completes payment for their original test, when requested within 90 days of release of the original result.
Glucose is absorbed by the digestive tract so it will not be able to detect SIBO that is further along in the small intestine (proximal jejunum/ileum). However, because of this, glucose is considered to be more sensitive than lactulose, providing less false positives with colonic bacteria. Review patient’s history prior to prescribing as this is not advised for patients with diabetes or certain sugar sensitivities.
Lactulose is not absorbed by the digestive tract and will travel through the entire gastrointestinal tract, ultimately providing a complete depiction of all intestinal segments, including the colon (large intestine). As lactulose is a prescribed laxative, evaluate risks for patients prone to diarrhea, without a colon, or other potential factors.
If the physician requests SIBO tests with both substrates, please note on the order form this is intentional.
Lactulose is a synthetic sugar solution, used as a prescribed laxative. The liquid lactulose substrate is provided in a small cup included in the kit.
Glucose is 100% glucose (dextrose) sugar provided in powder form in the amount of 75g. If you are sensitive and/or have diabetes (Type I or II), please consult with your healthcare provider if this substrate is right for you. (This substrate may be derived from corn.)
Fructose is 100% fructose sugar, provided in powder form in the amount of 25g.
Lactose is 100% lactose sugar, provided in powder form in the amount of 25g.
Sucrose is 100% sucrose sugar, provided in powder form in the amount of 50g.
CDI offers interpretation assistance to providers for all of our diagnostic test kits. Please note, CDI can only discuss the following as each patient’s symptom and history may vary: parameters of our test, test methods, most common results, and instrumentation questions. CDI does not provide treatment recommendations. Providers can find an explanation of the 6 most common results for hydrogen & methane breath tests here. CDI follows guidance from the North American Consensus on Breath Testing for all of our hydrogen & methane breath tests. A summary of the consensus can be found here, and the full consensus from the American Journal of Gastroenterology can be found here. For additional assistance, please contact our customer support team at 888-258-5966.
For any patient that has tested positive for COVID-19, CDI has adopted a corporate policy whereby you should not administer and return your test kit, and CDI will not accept samples from any known COVID-19 positive patient, until thirty days (30) have passed following a negative follow-up test for COVID-19 from your healthcare provider.
We are implementing this policy in an abundance of caution in order to provide for the safest possible environment for our patients as well as our employees and clinical staff. We thank you for your cooperation with our policies, we wish you a speedy recovery and good health, and we look forward to working with you in the near future to help diagnose your gastrointestinal symptoms.
For more information regarding test preparation, medication, or activity restrictions, and more, please review the patient-focused FAQ here: Patient Resources.
CDI will submit a claim on the patient’s behalf to commercial insurance, Medicare or Tricare. Insurance may cover some or all of the test depending on the patient’s insurance plan and benefits. In the event the patient’s insurance provider denies the insurance claim, or if the patient has not met the deductible or has a coinsurance or co-pay, or if for any reason the insurance does not cover the full amount of the test, the patient is responsible to pay CDI for products and services received. Please contact your insurance carrier(s) regarding coverage prior to testing, with the following information:
CPT Code: 91065 x 2 units, totaling $699.00
NPI: 1831625342
Tax ID: 47-4725769
CDI does not accept any Medicaid plans: therefore, any Medicaid patient taking a test will be responsible for the full cost of the test. CDI offers convenient payment plans and financial hardship programs for qualifying patients; patients should inquire prior to testing by reaching out to Customer Service at customerservice@commdx.com. Patients may pay upfront via check sent with the kit or credit card. The maximum out-of-pocket cost is $299 per breath test for patients that pay promptly in accordance with CDI patient billing policies and programs. For an updated list of in-network providers and additional information, please visit commdx.com/insurance. Please review this page and contact your insurance carrier(s) prior to testing.
