RESUMO

The authors address three issues associated with the implementation of the model proposed by Hsiao, et al. First, the mathematical model used and its underlying assumption, in particular as it relates to "time," is questioned. Second, the authors argue that measured rather than perceived (surveyed) data should be used whenever possible. This is particularly true for "time." Third, the authors raise the possibility that adjustments can and should be made based on the type and average complexity of examinations performed at different facilities. The potential implications of RBRVS reimbursement schemes on the practice of diagnostic radiology are significant and, once implement, they will be difficult to alter.
