Billing Options

Billing Options Image


The University of Iowa Diagnostic Laboratories (UIDL) produces client invoices once each month. The invoices itemize the date of service (collection date), patient name and date of birth, charge description, price and CPT code of each test performed. Payment of the invoice is due within 30 days of receipt. The client is responsible for applicable insurance and patient billing.


CPT Codes are provided in the University of Iowa Diagnostic Laboratories Test Directory Handbook as a convenience to our clients. CPT codes are subject to change at any time; it is the client’s responsibility to verify their accuracy for the test performed. Clients are encouraged to consult the CPT Coding Manual published by the American Medical Association and to address questions regarding the use of any particular code to their local Medicare carrier.


UIDL is a participating provider with Medicare and Medicaid, in addition to a large number of private insurance companies and managed care organizations. UIDL accepts assignment on all insurance payers accept Medicaid outside of Iowa.

Private Insurance and Managed Care Organizations
As a service to your patients, and in compliance with agreements established with insurance and managed care companies, UIDL will bill your patient’s insurance carrier(s) or managed care organization directly when provided with complete and accurate billing information. For those insurance companies and managed care organizations where a contract does not exist with UIDL, we will still file a claim to those carriers. Your patient may or may not have out-of-network coverage.


UIDL will bill Medicare for all physician services as well as laboratory (technical) charges associated with office visits.  In the event a health care practitioner orders tests that Medicare deems medically unnecessary, a properly executed Advance Beneficiary Notification (ABN) must be secured by the client prior to collection of the specimen. The ABN form must accompany the specimen to our laboratory. The ABN enables UIDL to bill the patient if Medicare denies our claim for medical necessity or frequency limitations. It is the client’s responsibility to ascertain the need for the ABN (refer to the Guideline Information). In the absence of a properly executed ABN, University of Iowa Diagnostic Laboratories (UIDL) will bill denied charges back to the client.


Medicaid claims can only be filed after all other third-party resources have been exhausted. Patients should be asked at the time of service if there is other coverage, such as Medicare, Medicaid HMO, or private insurance. When applicable, any Medicare, private insurance, or managed care (HMO) information should also be provided.  UIDL can only file Medicaid or state aid claims in Iowa.

If Medicaid denies payment for non-covered services or eligibility reasons, the patient may be responsible for the payment. Medicaid is always the last source of payment.


It is the patient/provider’s responsibility to obtain a referral for work sent to UIDL in the event the patient’s insurance carrier considers UIDL to be an out-of-network provider. UIDL makes billing as flexible as possible by providing many different payment options to our patients and customers. Depending on the arrangement your clinic, hospital, or health insurance plan has with us, you may or may not receive a bill directly from UIDL for all or part of the services provided by us. We do our best to obtain reimbursement from insurers without contacting you.

Some of the circumstances that can result in your receiving a bill from us are:

  • You have non-government insurance and are responsible for a co-payment, co-insurance, deductible, and/or non-covered services.
  • You have Medicare and are responsible for 20% of the amount Medicare has set as the cost of the test.
  • You have Medicare and have signed an ABN (advanced beneficiary notice). In this case, you may owe the difference between what Medicare paid and what they have set as the cost of the test.
  • Required prior authorization for testing was not properly obtained prior to testing.
  • The UIDL needs additional information to be able to successful file 3rd party payer claims on your behalf in a timely manner.

Please contact your insurance carrier directly, should you receive a bill from the UIDL and feel your insurance claims were not processed correctly.


If you receive a bill, there are several options for payment:

  • US mail:  Please return the top portion of your invoice with either a check, money order or credit cars information.
  • By phone:  You may call 319-353-7958 between the hours of 8 am - 4:30 pm to provide credit card payment.
