Why would I get a separate pathology bill?

A pathology bill is often separate because the tissue, blood, or lab sample may be reviewed by a pathology group that bills independently from the hospital or doctor who saw you.

Should I pay an out-of-network pathology bill right away?

It is usually better to compare the bill with your EOB first. You want to know whether the insurer processed it as out of network, whether the patient responsibility matches, and whether the charge may need review.

Pathology Bill Out of Network? What to Check Before You Pay

If you get an out-of-network pathology bill, do not assume you must pay it as billed. First compare the bill with your EOB, check where the specimen was processed, and see whether the charge came from care tied to an in-network facility or emergency visit. The next step depends on whether the bill reflects normal plan processing or a billing problem.
