Issue: CCDE logic includes all patients with Medicare at any time historically or currently. Many of these pts had Medicare at a time when MBI was not being used. Hospitals are trying to validate MBI prior to submitting the QRDA file and concerned that:

1) Historic Medicare patients included in the CCDE IPP / QRDA files (for which there was NO claim submitted for the reporting year) will impact their results (in the HSR) when calculated by CMS and/or impact meeting the requirements. Can you explain how these pt files would be handled? Confirm that they are 'filtered out' and will not impact a hospitals HSR results?

2) Missing MBIs - are these pts excluded from CMS calculations completely? Are the hospital's results (in the HSR) impacted if it is a historic Medicare patient with a missing MBI?
