Sentinel Lymph Node Mapping During Surgery

New Mexico rates for HCPCS 38900

During a cancer operation the surgical team traces and identifies the first lymph node or nodes that fluid draining from the tumor would reach, known as the sentinel node, so that node can be found and checked for cancer spread. A dye injected at the site may be used to trace the path, and tracing methods such as a radioactive tracer may be used instead or as well. The mapping is billed in addition to the main operation.
