Yah basic coding is not really hard to learn. Like it has been said, someone with very little education is often doing it many places.
Podiatry is a little different than other specialties with all of our modifiers and extensive rules on nails and diabetic foot care. Is is also a very procedure based speciality. The podiatry specific coding aspects will be learned quickly with experience.
A brand new practitioner will be overwhelmed thinking about what level E/M to charge.
A more seasoned practitioner may or may not be any better than the new associate as far as accurate E/M coding, but will be focusing much more on what pays well with the particular pathology and insurance plan as well as cash pay options available for each patient. It takes a while to get a feel for this and then suddenly it is obvious why treatment plans are the way the way they are for common pathologies at each individual private practice (different insurance mixes/disposable income levels, codes that pay well, different modalities owned by the practice, cash pay options, some have lucrative referrals, tolerance for risk of paybacks etc.).
RVU based hospital employed obviously think differently.
An unethical practitioner will blatantly change the pathology actually present to something that pays much more and also unbundle.
