Billing Services

Welcome to Billing Services. This section contains helpful information on the billing process - whether you bill your patients or have us handle the billing for you. Also included in this section is information on the Advanced Beneficiary Notice (ABN) and the ABN form.

Client Account Billing

If you elect client billing, an itemized statement will be rendered each month for testing services performed during the preceding billing period. Terms of payment are net 30 days. Please notify HealthLab within 45 days if you believe any portion of the statement is in error. Questions regarding your bill can be directed to the billing department at 630.933.6657.

Advance Beneficiary Notice (ABN)

Medicare has a complicated set of rules to determine if a test is eligible for payment. These rules exclude some testing that represents the standard of care in our community, including testing done for screening purposes and testing associated with a general physical. Payment may also be denied based upon the diagnosis associated with the test order or the allowed frequency of a specific test. An ABN is a written acknowledgement that advises beneficiaries, before items or services are rendered, that Medicare is likely to deny payment. ABNs serve as an important fraud and abuse compliance function that is the responsibility of all parties involved in supplying a service or item to a patient.

ABNs are not required for services that are never covered by Medicare. If a service is “never covered,” consider presenting an ABN to the patient as a tool to initiate conversation about the expense.

For laboratory services, the ABN “L” form may be downloaded from the Centers for Medicare & Medicaid Services (CMS) website: in both English and Spanish. Copies of the completed ABN must be given to the patient and kept on file in your office. The original must accompany the requisition with the specimen.
