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 root canal on a molar removes infected or damaged pulp from the tooth's roots, cleans and shapes the canals, and seals them. Molars have more canals than front teeth, so the treatment usually takes longer.
What the price covers
The fee usually covers all appointments to finish the root canal and X-rays taken during treatment. The exam and X-rays before treatment, a buildup and the crown that usually follows are billed separately.
