Claims submitted with reasonable proof must be paid within 30 days
. If the insurance carrier feels reasonable proof was not submitted, they must inform you in writing within 30 days of your submission. Properly submitted claims that remain unpaid after 30 days are considered overdue and bear simple interest at 12% as a penalty against the insurer. If the insurer unreasonably delays or refuses to pay, they may be subject to a penalty attorney fee as well.
