Help, my rating looks bad! Coding comorbidities in arthroplasty

In medicine today, there is a trend toward increasing transparency. Higher quality and better value are being sought, and one of the methods being used is publicly reported health care outcomes. However, there is a problem that comes from our loss of anonymity. Physicians who are being individually watched have to choose between doing what is best for the patient and doing what would look good when it is publicly reported. Often this might mean choosing not to treat a particularly sick patient who is unlikely to have a good outcome. Adjusting outcomes to account for risk factors should be a way to prevent this effect, but these methods need to be studied more. The current performance measures being released are based on administrative claims data, and to date, much of that information is not properly risk adjusted. To ensure that the increasing transparency reveals an accurate picture, it is critical that the complexity of care provided by surgeons be carefully documented. Therefore, we propose accurate coding of patients' comorbidities during hospitalization for total knee arthroplasty and total hip arthroplasty, and we have included a chart detailing our recommendations of the specific diagnostic codes that are most important.
