> Medicare paid $440.86 for CPT 64721 in the office (non-facility) setting and $437.64 in a facility under the Q2 2015 Physician Fee Schedule, effective April 2015. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2015, when it increased 1.1%.

## What it is

Surgery to free the median nerve where it is squeezed at the wrist. The surgeon divides the transverse carpal ligament, the tough band forming the roof of the carpal tunnel, which immediately enlarges the tunnel and relieves pressure on the nerve. It can be done through a small open palm incision or endoscopically, and the ligament is left divided rather than repaired.
