This can occur when a paid claim has been selected for review by CMS. When the claim is reprocessed, the last character of the TOB changes to an H. For examples, 32H or 81H (Hospice). Barnestorm does not have information on why the claim was selected for review or why monies may have been recouped. You can find information by pulling that claim up in DDE, or you can contact Medicare for more information regarding the claim.
