Billing Information

Client Billing

Clients receive monthly itemized invoices within the first week of every month. Payment terms are net 30 days.

Invoices can be accessed through the iLabBill Client portal, emailed as a PDF attachment, or mailed to the client’s address. We require that any notifications, changes, or errors be reported within 30 days of the invoice date.

All invoices include:

  • Patient name
  • Date of service
  • Test(s) performed
  • Accession number
  • CPT code(s)
  • Test price
  • Purchase order numbers (if provided)

Third-Party Billing

At the client’s request, we can submit payment claims to government, private, or individual payers. All Medicare plans are accepted in addition to third-party commercial insurers contracted with Cleveland Clinic Laboratories. Any third-party insurance that is not contracted with Cleveland Clinic Laboratories will be billed back to the client.

Medicare requires all providers who order or refer items for their beneficiaries to be enrolled in the Medicare program.  Only State of Ohio Medicaid plans can be billed by Cleveland Clinic Laboratories.

Patients are responsible for annual deductibles, co-payments, and any balance not covered by their insurance plan.

We accept assignments on Medicare and Ohio Medicaid billing.

Third-Party Billing Requirements

Incorrect or missing information regarding a patient, their diagnosis, and insurance are leading causes of lost or delayed reimbursement. To ensure that claims are submitted to the appropriate payer, please provide the following information:

Patient Demographics

  • Full Name
  • Date of Birth
  • SSN
  • Gender
  • Full Address
  • Phone Number

A copy (front and back) of each of the patient’s insurance cards

Ordering & Referring Physician Information

  • Full Name
  • NPI
  • SSN
  • Phone Number
  • Email Address

An appropriate ICD-10 diagnosis code for each ordered test

If the required information is missing, the client assumes responsibility and will be billed for all services.

Patient Billing

Patients may request services that are not covered by their benefits. Such services may be provided as long as the patient has completed an Advance Beneficiary Notice (ABN) and has agreed to pay for the services.

Please advise patients that they will receive a bill for laboratory services from Cleveland Clinic Laboratories and that they are solely responsible for these charges. Payment is due upon receipt of their bill. Checks and credit cards are acceptable forms of payment.

Patients can pay their bills online via the iLabBill Patient Online Bill Payment Portal.

CPT Codes

Current Procedural Terminology (CPT) codes are listed in our Test Directory to assist clients with billing.

For tests that involve several components, our Test Directory provides a comprehensive list of CPT codes for all of the possible testing components; however, only a subset of component tests may be performed on your specimen. All clients should verify the accuracy of any codes that are listed.

Because CPT codes are subject to change at any time, it is the responsibility of the client to verify the accuracy of the test(s) performed. Clients are encouraged to consult the CPT Coding Manual published by the American Medical Association and to address questions regarding the use of codes according to their local Medicare carrier.

Cleveland Clinic Laboratories does not assume responsibility for billing errors due to reliance on CPT codes listed in the Test Directory.

Credits & Cancellations

Cleveland Clinic Laboratories reserves the right to review credit reports from reporting agencies such as Equifax, TransUnion, and Experian.

All invoices are due in full upon receipt and must be paid within 30 days from the date billed.

All claims, requests for adjustments, or notifications of errors must be made within 30 days of the invoice date. If nothing is communicated within the 30-day time frame, charges are considered to be accepted.

Charges unpaid after 120 days are subject to collection. The purchaser will assume all collection expenses, attorney fees, and court costs.

Fee Changes

Fees are subject to change without notification.

Advance Beneficiary Notice

The ordering physician is responsible for ensuring that any laboratory procedures requested are medically necessary, as determined by federal guidelines.

A completed Advance Beneficiary Notice (ABN) form signed by the patient must accompany specimens that are expected to be denied by Medicare.

Printed copies can be ordered online from the Supply Storefront or downloaded as a fillable PDF.
