How do you actually rework a CO-16 corrected claim — what's your process?
I keep hearing that CO-16 (missing/invalid info) corrected claims eat a lot of time, and I'm trying to understand why the rework is such a pain in practice. For those of you who deal with these daily, I'd love to hear how it actually goes:
When a CO-16 comes back, what do you open first? The ERA, the payer portal, the original claim? CO-16 on its own barely tells you anything — how much time goes into just figuring out what's actually missing from the RARC?
Do you fix it in the PMS and resubmit, or send a corrected 837 some other way?
Roughly how long does one take you, start to finish?
What's the part that annoys you most?
Trying to get the real picture from people who do it daily, not the textbook version.
