What is the cost of testing?
The cost of each test, along with applicable CPT billing codes, may be found by scrolling to the bottom of each test description (under “See All Tests”)
How do I find out if my insurance will cover this testing?
You may contact your insurance provider to ask about coverage (or “preauthorization”) for the specific CDL test ordered, or ask us for help in obtaining pre-authorization. They may ask for the CPT code(s), price of the test (see above), our lab’s Federal Tax ID (91-1220843) and/or NPI# (102 304 1159).
The CPDx can file pre-verification/pre-authorization with the insurance company on your behalf. To initiate this service, please ask your provider to complete the CPDx INSURANCE VERIFICATION FORM. Please consult our Billing page for more information
What do you need to bill my insurance?
We ask for a photocopy of the front and back of your insurance card, along with completion of all information in the “Insurance Billing” section of our test requisition form.
What if my insurance denies testing?
If genetic testing through the CDL is denied, your physician may need to submit an appeal letter on your behalf. Here is an example of an APPEAL LETTER OF MEDICAL NECESSITY AFTER DENIAL OF GENETIC TESTING.
Do you offer financial assistance?
In the event a patient is not able to afford testing (or insurance is billed and denies coverage) the Collagen Diagnostic Laboratory offers several options through University of Washington Physicians (UWP), including a monthly payment plan, full pay discounts, and charity care options. Please contact the UWP at 206-543-8606 or 888-234-5464 for more information.
