G6016 — Compensator-based beam modulation treatment delivery of inverse planned treatment using 3 or more high resolution (milled or cast) compensator, convergent beam modulated fields, per treatment session
G6016 is a HCPCS Level II code for compensator-based beam modulation treatment delivery of inverse planned treatment using 3 or more high resolution (milled or cast) compensator, convergent beam modulated fields, per treatment session. It belongs to the Procedures and Professional Services (Temporary) section. It was terminated on December 31, 2025 and is not valid on new claims.
This code has been terminated
CMS terminated G6016 on December 31, 2025. It stays in the file as history — a claim you are auditing from before that date may legitimately carry it — but it must not appear on a new claim. The adjacent codes below are the usual place to look for its replacement.
