Hello all! I have a question regarding Medicare, hoping someone will share wisdom with me. My question is: with the new Medicare change regarding provider enrollment only retro 30 days, what happens with claims that fall during the "non-par" status? (Non-par status being the time provider practicing prior to the date of effective participating status with Medicare). According to the EOMB I received, these claims are all patient responsibility. We were unaware there would be issues during the enrollment process that would cause these claims to be non-par, and we are appealing, but in the meantime......... I guess I wonder: if the claims have accept assignment checked, then shouldn't 'something' other than zeroes process on EOMB? I really appeciate any help offered!! THANKS!
