Get the patient's share in dollars, from the benefits page

Most denials can be seen coming on the benefits page. Tabruns reads the coverage, deductible, yearly maximum, waiting periods and frequency limits from the insurer's portal and works out what the patient owes. Patient details stay on the office computer.
