I'm guessing a lot of people run into this: Before performing a procedure, we check benefits and eligibility, the insurance says no prior authorization is required. When we bill for the procedure, they deny for no prior authorization. Usually we're not able to get the "No Auth Required" in writing. When we say Jane told us no prior auth required, and provide the reference number from the call, they say no one told you that. Or they send to reprocess, and it still gets denied. What can we do to avoid this? The denied claims are really adding up, and it eats up a lot of time with few good results. I would appreciate any helpful tips.
