In this article, we presented counts, rates per 100 veterans, and costs of 29 potentially low-value services across 6 domains (cancer screening, diagnostic and preventive testing, preoperative testing, imaging, cardiovascular testing and procedures, and other procedures) delivered in Veterans Health Administration (VA) facilities and in VA Community Care programs. In primary analyses, when computing rates of lowvalue service use per 100 veterans, we used a denominator of all veterans continuously enrolled in the VA during fiscal year 2017-2018 with 1 or more inpatient or outpatient encounters in fiscal year 2018.In eTable 4, in the Supplement, we presented the results of a sensitivity analysis in which we computed rates of lowvalue service use per 100 veterans using service-specific denominators consisting of veterans who were considered at risk for receiving each low-value service of interest, based on clinical criteria that render the service to be of low-value (eg, only veterans with a history of low back pain are at risk for receiving low-value back imaging). While working on a manuscript for another study, we discovered a programming error that resulted in the use of incorrect service-specific denominators for the rates reported in eTable 4. The error did not affect the main findings of the study.Corrections to address this error affect column 2 (At-risk for low-value services [N]), column 4 (rate/100 Veterans at risk for low-value services − Specific), and column 6 (rate/100 Veterans at risk for low-value services − Sensitive) of eTable 4. Columns 3 and 5, which report the raw counts of each low-value service, are unaffected. Corrections also affect the correspond-
