Knee arthroscopy with meniscus repair in Dallas, TX costs $3,270 to $21,427. Here's every hospital's price.

CPT 29881 is a keyhole knee operation to trim a torn meniscus, the cartilage cushion in the knee. It is one of the most common orthopedic procedures, done as an outpatient in 30 to 60 minutes under general or spinal anesthesia, with a few weeks of recovery.

What the price covers

The hospital's price is the facility fee: operating room, arthroscopy equipment, nursing, supplies and recovery. The surgeon and the anesthesia provider bill separately. Post-operative physical therapy and a knee brace are separate.

Is it needed?

For degenerative meniscus tears in middle age, trials have found physical therapy works as well as arthroscopy for many patients. If the tear is degenerative rather than from an injury, it is reasonable to ask whether a course of therapy first would be sensible.

Why prices vary

The same operation is priced several times higher at some hospitals than others in the same area, and ambulatory surgery centers, which do not publish these files, are often the cheapest option. Ownership and system size drive hospital prices more than anything else.
