# CPT 64555

> Medicare paid $1,236.59 for CPT 64555 in the office (non-facility) setting and $350.64 in a facility under the Q1 2018 Physician Fee Schedule, effective January 2018. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This is a 475.2% increase from the previous quarter.

## What it is

Placement of a stimulator electrode next to a peripheral nerve through the skin, using a needle rather than an open incision, usually with ultrasound or x-ray to find the nerve. Once in place the electrode delivers mild electrical pulses to that specific nerve to dampen pain signals. This covers peripheral nerves out in the limbs, trunk, or head - the sacral nerves have their own separate code - and it is the lead-placement step, not implantation of the generator that powers it.
