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
Carpal tunnel release cuts the ligament across the palm side of the wrist to take pressure off the median nerve. It is done for numbness, tingling and weakness in the hand that do not improve with splints or injections.
What the price covers
