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

An endometrial biopsy takes a small sample of the uterine lining with a thin tube passed through the cervix, without stretching the cervix open. It is used to investigate abnormal bleeding, such as bleeding after menopause.

What the price covers

The price covers taking the sample. The pathologist's exam and the office visit are usually billed separately.
