I have secondary insurance. How do I submit a claim to them?
Secondary insurances need your Explanation of Benefits (EOB) in order to process a claim. Submit the EOB from your primary insurance, along with your Westcliff statement, to your secondary insurance company's claims processing address. I received a bill from a lab other than Westcliff, but Westcliff received the lab samples.

Why am I being billed from this other lab?
Westcliff Medical Laboratories performs over 99% of all Laboratory tests ordered by our physician clients. On occasion a test is sent to an outside reference laboratory, Westcliff will not bill for this test; the laboratory performing the test will bill for the test. Therefore, you will receive a billing statement from the reference lab that is separate from Westcliff bill. If you have any questions, please contact us at 949-724-3900.
