...Some of our office procedures are more technical and invasive than these and yet we are paranoid to bill 4’s. Are people actually getting audited for justified 4’s or have we just been reading too much PM News with foot baths being billed as 4’s?
As mentioned, there certainly are some 99204 ingrown visits. Making every single one that level is very likely to make the office into a tallest blade of grass, though. It is virtually impossible to have decision complexity for 99204 on most basic ingrowns (kids, healthy adult, maybe unhealthy but basically no other foot complaint, already on abx from ER, specifically already referred for that complaint, etc). It is possible to try 99204 based on time if one sees low volume.
In the end, a lot comes down to what peers (same specialty / tax category) are doing. DME is probably the biggest example lately, but it can apply for any procedure code/set. That is doubly so if one sees any kind of volume or stays above peers for an extended period (many more of certain code/codes, higher avg E&Ms vs peers, way more XRs or DME or whatever).
....Keep in mind nearly anything can work for a few years (upcoding, bad surgery, procedures never done, prefab DME billed as customs, gross overutilization of testing, etc etc). Nothing gets tagged and investigated the very next week after the visit was billed or even right after it was paid. This is why the 'hot tips' for coding are usually newer ideas, codes from a different specialty that podiatry is now starting to hammer on, etc. It's the longer term trends (usually vs peers) or patient complaints that usually attract the magnifying glass. The mag glass isn't always disaster, but it's stressful and can result in big claw backs, wasted time sending audit charts, attorney consult fees, or much worse if the documentation isn't there or the codes were wrong, not done, or level not supported. I wouldn't say it's 'paranoid' to code WNL to peers; most ppl just don't want to make themselves low hanging fruit to even start that payer eval or audit process... they'd rather just keep the golden goose humming along happily.
