Chemotherapy Measure (OP-35)
The Centers for Medicare & Medicaid Services (CMS) originally developed the chemotherapy measure with the support of multidisciplinary clinical and research experts and in accordance with development guidelines. CMS convened a Technical Expert Panel (TEP) of physicians, nurses, patient advocates, and experts in quality improvement to provide input on key methodological decisions during measure development, and continue to meet with the Expert Working Group to support measure reevaluation.
