[Add incentives](/bulk-billing?item=15990) Item descriptor --------------- Proton beam dosimetry, and proton-photon comparative plan reporting, to assess eligibility for proton beam therapy via the Medical Treatment Overseas Program if: (a) proton planning is required to calculate dose to single or multiple-target structures and requires a dose-volume histogram to complete the planning process; and (b) the proton planning process optimises the differential between target dose, organs at risk, and normal tissue dose, based on review and assessment by a radiation oncologist; and (c) all relevant gross tumour volumes, clinical target volumes and organs at risk are rendered as volumes and nominated with planning dose objectives; and (d) organs at risk are nominated as planning dose constraints; and (e) dose calculations and dose-volume histograms are generated in an inverse planned process, using a specialised calculation algorithm, with prescription and plan details approved and recorded with the plan; and (f) a three-dimensional or four-dimensional image volume dataset is used for the relevant region to be planned and verified; and (g) the final proton dosimetry plan is: (i) validated by a radiation therapist and a medical physicist, using quality assurance processes; and (ii) approved by the radiation oncologist; and (h) a proton-photon comparative plan report is generated; and (i) the service is bulk-billed [Explanatory notes and rules on MBS Online ↗](https://www9.health.gov.au/mbs/fullDisplay.cfm?type=item&q=15990) Health fund and DVA rates ------------------------- Total fee each scheme recognises for this item in hospital.
