We are having issues with insurance carriers paying for our 59425 and 59426 codes. Carriers often deny because of timely filing as we put a from date (the date the patient started their care with us) with a to date (the last date the patient saw us for their antepartum care). It seems the payer picks up on the first date which is the from date and of course it's greater than 120 days and they deny timely filing. How do you bill your antepartum only - can you offer me resources. We are in TN and have the hardest time with our MCO Wellpoint. Also, how many antepartum visits do you consider for OB global billing when you do the delivery and post partum care? Most policies say "about 13". Someone said ACOG say 7--. Any resources you can provide on any of these questions would be appreciated?
