Cash or insurance?
At 3 of 8 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 1 it is below every plan's rate. 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
ACL reconstruction rebuilds a torn anterior cruciate ligament in the knee with a tendon graft, using a small camera and instruments through small cuts. It is commonly done for knee instability after a sports or twisting injury.
What the price covers
The facility price usually covers the operating room, recovery and often the screws or anchors; a donor tendon graft, if used, may be listed separately. The surgeon, anesthesia (often with a nerve block) and physical therapy afterward are billed separately.
