Radiation Oncology-Correct provider

Good morning,

I have a question for all Radiation Oncology Coders. Who is the proper provider for services rendered. Currently we code everything with the Oncologist as the provider, amd I am not sure that is correct. We are a facility.

I know certain codes are technical only and some are combination codes.

For example:

Radiation treatment- 77418 - technical only should the technition be the provider, or the oncologist?

Isodose plans- 77315 (technical and professional) -

IGRT- 77421- (technical and professional)

Any assistance or direction is greatly appreciated.

Thank you,

Radiation Oncology-Correct provider
