Hello everyone ,
Needing some assistance with a denial code CO-109 we billed L1830-LT but it came back as unprocessable and to send to correct payor. I am Jurisdiction D . Who do I submit it to? And/ or what modifiers am I missing? Thanks!!
 
Go on CSNAP and check the patient’s Medicare eligibility. It will tell you if they have a Medicare advantage plan. If the MCO box is highlighted, click on it and it will tell you which plan they have. That is the most likely cause for the CO-109 denial.
