What it is

This code covers replacing only the worn part of the knee joint, usually the inner side, instead of the whole joint.

What the price covers

The hospital price usually covers the operating room, recovery and supplies. The surgeon and anesthesia usually bill separately.

Why prices differ

Ambulatory surgery centers often charge much less than hospitals, and hospital prices for the same operation vary widely.

What to ask

Ask whether the self-pay price for CPT 27446 is a bundled price that includes the surgeon, anesthesia and follow-up visits.
