Insured Patients

Who files the insurance claim?

A2Z will file claims directly with your Insurance provider.
It is therefore imperative that A2Z have accurate and complete billing information. Please provide us with any secondary insurance that supplements your primary coverage so that we can file the claim with the secondary carrier.

What is the Patient responsibility?

Federally funded programs and state specific laws do not permit the routine waiver of patient responsible amounts (deductibles, coinsurance, or copays).
It is the policy of A2Z to bill any secondary insurance payers for the deductible, coinsurance, and copayment amounts. If after all payers have remitted payment, it is A2Z’s policy to bill and collect from the patient any remaining amounts from any deductibles, coinsurance, or copayment as determined by the insurance payer.

A2Z accepts personal checks and all major credit cards. Payments may be processed through A2Z’s billing vendor or online through the A2Z web portal.

What if Insurance information is not provided?

            If insurance information is not provided, we may send the patient a bill for the charges.

What if Insurance company does not pay?

If A2Z has already billed the insurance company and have had no response from them after a reasonable length of time, A2Z may contact the patient to assist us with the insurance company to process the bill and/or appeal the claim. This is to avoid any possible timely filing issues with the insurance carrier.

In the event that A2Z does not participate in an insurance network, please contact our billing department.

What if Insurance company does not fully cover the services?

A2Z will work with the patient to establish reasonable payment arrangements. The patient will only be sent to a collection agency if they fail to forward payments received from their insurance company to A2Z for services. Sending patients to a collection agency will be A2Z’s last resort.

What is an EOB (Explanation of Benefits)?

Once your insurer has processed your claim, you will receive an Explanation of Benefits (EOB) from your insurer informing you of the amount it will pay for your laboratory services. The EOB is not an invoice or bill, but it may indicate that a balance remains which is your responsibility. That balance may include your copayment, deductible, or other costs outlined in your terms of coverage. If you have a question about your EOB or your terms of coverage, contact your insurance company.

Uninsured Patients

What if I do not have Insurance?

If you do not have insurance or your health care benefits do not cover clinical laboratory testing services, you will have to pay for the tests performed by A2Z.

Often these tests are available at a discounted price or costs are waived if financial hardship can be documented

A2Z accepts cash, personal checks, and all major credit cards. Sending patients to a collection agency will be A2Z’s last resort.

Stool Collection FAQs

What, exactly, do I have to do?

Instructions are provided with each kit. Or you can click here for stool collection instructions.

Why do I have two tubes to fill, one with liquid and one without? How much should I fill each one?

The tubes are different because your doctor wants us to run different tests. The tube with the blue top and the scoop should be no more than half filled. For the tube with the liquid use the swab to obtain a small sample of stool. The swab is then placed into the tube with the liquid and the cap is secured tightly on the tube. Do NOT use the swab more than one time. Only a small amount is needed for testing.

When will you get my stool sample?

Stool samples are sent priority overnight, so we will receive it the next day.

How long will my stool last, in case I get it in the tubes but can’t sent it right away?

Fresh stool (in tube without liquid) must be sent to the lab within 24 hours. Stool samples in the tube with liquid may be kept at room temperature for up to 4 days. The sooner you send it the better.

I accidentally got urine (or menstrual blood) mixed into my stool sample. Is it still okay to use?

Preferably not, it is best if a stool sample is not compromised by water, blood, or urine. Try to take specimen from an area on the collection device that hasn’t been contaminated.

My paper collection device fell into the toilet. Can I still send the sample?

No. The toilet might have contaminated the sample. It is best if a stool sample is not compromised by water, blood, or urine.

I only went enough to fill one sample tube. Can the samples come from different bowel movements?

Yes, they can.
