Where our data comes from - The data you see on providers' Healthgrades profiles comes from both the provider and public sources. The Top Care Areas section uses public data from billing claims that providers submit to insurance companies. That data is filed nationwide on behalf of the provider to either the government or a private health insurance company.

How we evaluate our data - Patient volume is analyzed by provider and compared nationally with all providers who perform the same procedure, or treat the same condition. We organize the volume data in percentile ranking from 'may perform' for the lowest claims volume to 'Very High' for the highest claims volume data. For a given condition or procedure, performance categories are defined based on 80%, 90%, and 95% confidence intervals from the average patient volume for all providers in our database. Providers identified as ‘may perform’ do not have sufficient volume for Healthgrades to create a statistical evaluation.
