Medical billers — how do you actually handle a CO-16 corrected claim?
I'm trying to understand the real workflow for administrative denials, especially CO-16 cases where the RARC points to missing or invalid claim information. When you receive one, what do you actually do first? Do you open the claim in your PMS/EHR, make the correction there and resubmit? Or do you ever work directly with the 835/837 files or upload a corrected 837 through your clearinghouse? One thing I'm specifically trying to understand: if a corrected 837 were already prepared for you, would uploading that file to the clearinghouse actually eliminate work — or would you still need/want to open and update the claim in the PMS first? I'm not looking for patient data or examples containing PHI. I'm just trying to understand the workflow from people who actually work these denials.
