An Overview of the Radiation Oncology Alternative Payment Model and Impact on Practices Serving Vulnerable Populations.

Radiation oncology reimbursement methodology has been largely unchanged over the past 30 years, and new approaches are of great interest to practicing radiation oncologists and other health care stakeholders. Traditional radiation oncology reimbursement is based on a series of individual codes for evaluation and management (professional) and technical services, yielding a complex reimbursement system. In an attempt to move toward a simpler, episodic payment model, bundling all of the codes into a single payment, an alternative payment model for radiation oncology was developed. The radiation oncology alternative payment model is a revolutionary change in how radiation oncologic services will be reimbursed and has potential to affect all aspects of radiation oncologic care. Here, the authors review the origin of the currently proposed radiation oncology model and discuss potential implications of this model on the provision of care, especially as it relates to rural practices and other underserved and vulnerable patient populations.
