Bone Lengthening With An Internal Rod

Massachusetts rates for HCPCS 0594T

Cuts a long bone and places a powered rod inside its hollow center, which is then extended a fraction at a time by a controller held against the skin so new bone fills the widening gap. The service covers the operation itself along with the alignment checks, the worked-out adjustment schedule, and management of the rod while lengthening goes on.
