Overutilization of IMRT/IGRT in treatment of rectal cancer: Cost implications of deviation from evidence-based practices.
2014
34 Background: Current evidence-based guidelines for management of rectal cancer (RC) caution against routine use of IMRT and do not address the role of IGRT. To explore patterns of care and cost implications for treatment of RC in commercially insured patients, we assessed treatment requests submitted for preauthorization through eviti Connect. Methods: A proprietary web-based application enables oncology providers to obtain automated precertification for patients insured by payers across the US that use the platform. All requests for pelvic radiation for treatment of RC submitted from 6/1/11-5/31/14 were reviewed. Treatment delivery costs for 3D CRT + weekly port films and for IMRT + IGRT were calculated based on average reimbursement rates from 3 payers for a typical course of 50.4 Gy/28 fractions. Results: A total of 195 cases for treatment of RC were submitted. At submission, 50.3% (98/195) of cases met evidence based standards and received automated preauthorization; 49.7% required treatment justifi...
