Can you bill Worker's Compensation for my claim?

Yes, we normally can bill Worker’s Compensation, but we need this information: your social security number, the name of your employer, the date of injury, your Worker’s Compensation claim number and the name and address of the Worker’s Compensation carrier. (The carrier is usually your employer – in some states, it’s the Worker’s Compensation Commission.)

I cannot locate a treatment or diagnosis code on my statement?
We don’t show treatment and diagnosis information because we handle only the billing portion of the medical process. If you have questions about your treatment, diagnosis or other medically-related questions, contact your health care provider.
Why did I receive a bill from the hospital and the physician's or specialist's office?
The hospital bills you for the use of their facility and the supplies used during your stay. The physician or specialist bills you for services that he or she performed.
Will you bill my secondary insurance organization?
Yes, we’ll bill your secondary insurance organization, but we need this information; your insurance organization’s name and address, your policy and group numbers and the policyholder’s name and employer. We will file your secondary insurance once as a courtesy.
How can I find out if my insurance company has paid this claim?

Please read your bill carefully. A line-item adjustment will be printed on your bill if we have received payment from the insurance company.

How do I file a claim using secondary insurance for the remainder of my lab bill?
How do I file a claim using secondary insurance for the remainder of my lab bill?
If you have more than one insurance policy, you must submit to the secondary insurance company directly with a copy of your Explanation of Benefits (EOB) from your primary insurance company. Mail the bill you received, along with the EOB, to your secondary insurance company’s claim processing address. Understanding your EOB
Medicare requires the ordering provider to supply diagnostic codes of why lab work is being performed. Medicare generally does not pay for “routine lab work” and the patient will be responsible for payment in these scenarios. To request a Medical Necessity booklet please call (800) 633-4227 or (877) 486-2048.

If the diagnostic codes provided do not justify medical necessity or if a certain test has frequency limitations, we may ask for the patient to sign an Advanced Beneficiary Notice that states we are uncertain if Medicare will pay for this and the patient may be responsible for payment. A valid ABN list the test(s), gives a reason why the test(s) may be denied, and has the patients’ signature that if the test is denied, the patient will be fully responsible for payment.

If Medicare denies a test as not medically necessary or routine, PLA will verify that an ABN was signed and bill the patient. If an ABN was not signed, and client collected the specimen(s) in their office, PLA will have no recourse except to bill the requesting physician for the test(s) ordered, since failure to do so could invoke the anti-kickback statutes that pertain to physician/laboratory relationships.

If an ICD10 code or diagnosis is not written on the requisition or submitted with an electronic order, PLA will contact the client by fax to obtain an ICD10 code. If the ICD10 code given does not justify medical necessity, PLA will attempt twice to notify the client.

We urge the patient to call their physician if there is any question on the diagnostic code that is being submitted. Your physician will need to contact PLA if a change in diagnosis codes is needed.

Self Pays

Patients are encouraged to pay at the time services are rendered or must supply address and phone number to be billed. We offer a 50% discount to all self pay patients. 

Insurance Filing

Pathology Laboratory Associates will file Primary and Secondary with any insurance so long as all required billing information is provided by the patient and/or client. Depending on plan and whether PLA is in-network, patients may be responsible for the entire bill, co-pay or deductibles. It is the patient’s responsibility to verify if PLA is in-network lab.
