Surface Radiation Source Application

Massachusetts rates for HCPCS 77789

Radiation treatment given by placing a sealed radioactive source directly against the surface being treated and holding it in contact so the dose builds up gradually. The source gives off its radiation at a low rate over the treatment period, and tissue deeper down receives far less than the surface itself.

Rates data updated July 2026.
