Cash or insurance?
At the one hospital here that publishes insurer rates for this code, the cash price is below the highest rate a health plan has negotiated. If you have insurance but have not met your deductible, you usually pay your plan's negotiated rate, which falls somewhere in the "Insurers pay" column. Paying cash can cost less, but a cash payment usually does not count toward your deductible. Ask the hospital for both numbers before you book.
What it is
A PET/CT scan combines a PET scan, which shows how active cells are after a tracer is injected, with a CT scan that shows anatomy. This code covers the usual area from the base of the skull to mid-thigh. It is mostly used to find, stage and follow cancer.
What the price covers
The hospital price usually covers the combined scan. The radioactive tracer is often billed separately, as is the radiologist's or nuclear medicine doctor's reading.
