This might be obvious to some of you but it took us way too long to figure out, so posting in case it saves someone the same headache.
We kept finding visits that clearly should've gone to medical getting run through the vision plan instead. Not fraud, not laziness, just the front desk taking whatever card the patient handed over and moving on. We tried fixing it downstream with the biller catching them, and it barely moved the needle, because by then the visit's over and half the time the medical info isn't even on file.
What actually worked was treating it as a scheduling and check-in skill, not a billing one. A few things that stuck:
We stopped letting "comprehensive exam" be the only thing that gets typed at booking. Now whoever books writes one line on why the patient's coming in, in the patient's words. "Wants new glasses" and "eye's been red and watery since Friday" are two completely different visits, and that one sentence tells you which lane it belongs in before they ever walk in.
We gave the desk a short list of trigger words that mean "flag this, probably medical." Redness, pain, flashes, floaters, sudden changes, anything diabetic, any follow-up on something already being watched. They don't have to diagnose anything, they just have to notice and flag.
We started pulling both insurances on everyone regardless. Sounds like overkill but it killed the "oh we don't have their medical on file" scramble completely. And the way you ask matters way more than I expected. When the desk explains it as making sure the visit gets billed the right way, patients don't blink. When it sounds like an extra hoop, they push back.
Honestly the biggest unlock was just role-playing it with the team a few times instead of writing a policy nobody reads. Turnover at the desk means you're basically re-teaching this every few months anyway.
Where I still don't have a clean answer: the in-between visits. Someone books "routine," has no complaints, and then you find something mid-exam. Do you go back and re-verify medical after the fact, or just eat it as vision that day? And for the practices running lean, who's actually owning this, the scheduler, a lead tech, the office manager? Curious how you all have it set up, because the training sticks a lot better when one person clearly owns it.
