Medicare requires contractors to pay your clean claims within 30 days, but private payers differ by state. You've submitted a claim that you know is clean, you've waited three months, and you still haven't collected. Do you have any recourse? Yes, thanks to the prompt pay laws that each state must follow when paying your medical claims. What are prompt pay laws: Each state requires private insurers to pay all clean claims within a certain time frame. If the insurer does not pay the claim in a timely manner, then the payer is subject to paying interest on the charges owed to the practice (or directly to the beneficiary). Although each state publishes its own individual law, most range from 15 to 45 working days, with 30 days about the average. How to find yours: Better option: Caveat: States Take Rules Seriously If you thought the prompt pay rules were simply fluid "guidelines," think again. Last month, the New York State Insurance Department fined 20 health insurers over $700,000 for violating that state's prompt pay law. "The Prompt Pay Law has been extremely effective in ensuring that consumers and health care providers are paid in a timely fashion and it remains an excellent deterrent against entities slow to pay undisputed claims," said New York State Insurance Dept. Superintendent James Wrynn in an Aug. 24 statement. If your private payer consistently lags on paying claims and fails to meet prompt pay law requirements, in most cases, you are due interest. New York, for example, pays interest at the greater of 12 percent per year or the state's corporate tax rate, according to information on the state's Web site. In Illinois, insurers must pay interest at the rate of 9 percent per year, the state Web site indicates. Most states employ consumer hotline numbers so you can contact the insurance department directly if you want to dispute whether your claim was paid on time. You should contact your state medical association or insurance department if you feel your claim was not paid in a timely manner. For Medicare payers, contact your carrier directly if you feel your claim has not been paid in a timely manner.
