The Harvey L. Neiman Health Policy Institute studies the value and role of radiology in evolving health care delivery and payment systems, including quality based approaches to care and the impact of medical imaging on overall health care costs. Neiman Institute research provides a foundation for evidence-based imaging policy to improve patient care and bolster efficient, effective use of health care resources. Read the 2016 Neiman Institute Annual Report.

Neiman Imaging Types of Services (NITOS) codes provide a variable that can be merged into datasets by HCPCS code to identify imaging procedures by modality and anatomic site. This new coding system augments the existing BETOS system for imaging focused studies, and was designed to be usable either in conjunction with or in lieu of BETOS for imaging analyses.

 

NITOS NMBF

 

Each specific character in the NITOS four digit code indicates whether the procedure is: 1) invasive or non-invasive; 2) modality; 3) body region; and 4) focus area.   For a detailed description for how NITOS was developed and can be used please see NITOS Mapping Methodology and our policy brief.
