Design:Using 100% Medicare claims data, we identified patients aged 66–99 undergoing elective inpatient surgery (coronary artery bypass grafting, colectomy, and total hip/knee replacement) in 2014. We calculated price-standardized Medicare payments for the surgical episode from admission through 30 days after discharge (episode payments). On the basis of predictor variables from 2013, that is, Elixhauser comorbidities, hierarchical condition categories, Medicare’s Chronic Conditions Warehouse (CCW), and total spending, we constructed models to predict the costs of surgical episodes in 2014.Results:All sources of comorbidity data performed well in predicting the costliest cases (Spearman correlation 0.86–0.98). Models on the basis of hierarchical condition categories had slightly superior performance. The costliest quintile of patients as predicted by the model captured 35%–45% of the patients in each procedure’s actual costliest quintile. For example, in hip replacement, 44% of the costliest quintile was predicted by the model’s costliest quintile.Conclusions:A significant proportion of surgical spending can be predicted using patient factors on the basis of readily available claims data. By adjusting for patient factors, this will facilitate future research on unwarranted variation in episode payments driven by surgeons, hospitals, or other market forces.
