Frequently Asked Questions

Some patients are unable to pay balances in full and need extended time to pay for services. Mather Hospital offers short-term financing options to assist in these situations. All patients qualify by agreeing to accept the terms of the Mather Hospital payment program.

Please contact the 631-476-2801, option #2 to establish a payment arrangement. Note: Sending a partial payment does not establish a formal payment plan.

Insurance claims are submitted within days of service to Medicare, Medicaid, commercial, managed care, liability and other carriers.

Patients who have the ability to pay are expected to pay any known co-pays, deductibles and non-covered amounts when services are received. All requests for payments are based upon estimated amounts and are not considered final billing totals. A statement of any remaining balance will be sent once your insurance company has processed your claim. The balance is due and payable upon receipt of your statement. Insurance claims are submitted as a courtesy service and do not relieve patients of financial obligations.

If a patient’s account(s) become past due, Mather Hospital may pursue outside collection activity, including legal action, if necessary.

Many diagnostic tests and procedures performed at Mather Hospital consist of two parts:

  • Technical (hospital services)
  • Professional (physician services)

You will receive separate bills for Technical and Professional service rendered at Mather Hospital. Please contact the Patient Financial Services Department at (631) 476-2801 for all Technical/Professional billing questions.

Upon receipt of the primary insurance payment or denial, secondary claims are processed. Typically, the secondary claim is submitted with the primary insurance explanation of benefits, payment or coverage within days of notification.

Once your insurance company has processed your claim, they will send you an explanation of benefits. The explanation will provide payment amounts, adjustment amounts and any denials associated with your benefit plan.

It is a predetermined amount of money that a person commits to pay before the insurance company is responsible for any benefit payments.

A co-payment is a required payment by the insured to pay a set or fixed dollar amount (i.e. $35, $50, etc.) each time a particular medical service is provided.

Co-Insurance is the portion of medical costs that are shared by both the insured (the patient) and the insurer.

Please be aware that our facility is required by the federal government to add an 9.63% surcharge to all inpatient and outpatient hospital bills.

Accounts exempt from the NYS Surcharge: Medicare, Medicaid, federal employees and outpatient lab fees.

Mather lists the insurance plans we participate in here.  However you should contact your insurance carrier to confirm if our facility participates with your insurance company. Most insurance companies provide their contact information on the back-side of the patient’s insurance card.

The Emergency Room will provide you with a “No Insurance Card” form that will need to be completed and returned to the Hospital Business Office within 48 hours of your visit. If for any reason you lose this form, please contact (631) 473-1320 Extensions: 4342 or 4243.

If an insurance carrier denies your claims due to a Coordination of Benefits (COB), please contact your insurance carrier immediately. If your insurance carrier sent information to your home requesting additional information necessary for them to process and pay your claim, please contact them in order to avoid total financial responsibility for your unpaid claim.

If your insurance carrier requires a Student Status Form for your son/daughter who is a full-time student at a college/university please contact the college/university Bursar’s Office to request a Student Status Form. The Student Status Form must be completed by the college/university your son/daughter is attending. The completed form must have a raised university seal on it. After you obtain the completed form with a raised seal, please forward it to your insurance carrier.

A financial counselor is a member of Mather Hospitals’ Patient Admitting Services team who is dedicated to assisting patients in identifying and/or determining healthcare coverage or sources of reimbursement that may be available to them, whether from commercial insurance or government programs.

As a not-for-profit healthcare provider, it is imperative for both patient and hospital, that any and all means of reimbursement for hospital services are identified.  Our financial counselors work closely with patients as early in the admitting process as possible to ensure that the necessary documentation, research, and approval can be completed before services are provided.
