I am going to start billing from our office for patients at the rehab hospital which my doc rounds on daily. The facility has been doing this. When I bill for hospital patients I wait and enter all the chgs when discharged. But since these patients can be at the rehab center for 30 days should I submit the chgs daily or weekly? We use Greenway software and I'm trying to figure out how to get reimbursed the quickest way.
