Cash or insurance?
At 2 of 2 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at none is it below every plan's rate.

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.
