Wound/infect pts have little to no insurance.
The hospital FTE docs get paid on wRVU. The patient could have no insurance, MCA, whatever... pay is same: wRVU rate.
In PP, you want many, many well-insured pts who come to you in a defined schedule from refer sources (PCPs and maybe ER or other).
Pus bus does
none of those things PP thrives on... educated and therefore well-insured and well-employed ppl with reliable transportation don't (statistically) have very high rates of DM or related complications. If the higher edu/finance ppl are DM, it'll typically be well-controlled by Endo or IM with few or no complications due DM education and compliance. At the end of the day, diabetes (DM2) is a side effect of being out of shape and low education; those are facts proven many times over. Obesity and DM are a lot lower in educated populations; they maintain their weight better and just don't bomb the glucose receptors so hard with the candy and fast food. Therefore, not only do wound/amp ppl
not help your PP goals of good payers and good schedule above, they do the reverse: they
screwww your other private pt appt times, and they consume your lunches, evenings, weekends, etc to round and do the surgery (as PP docs seldom/never get paid for call).
Basically, in PP, you want to dump the wound/pus/amp pts onto hospital and their employed docs (who don't mind them since they get paid to take call and paid in wRVU) as much as possible. Most of them are their pts to begin with (as they have had wounds before and/or use ER as their PCP). Even the mediocre insured (MCR) pts with wound/amp stuff are very time and resource consuming for PP, and you typically want that office time filled with better stuff. The wounds clog the schedule, have complications (aka not taking care of themself) that require urgent attentions, and they pop up again and again despite good shoes/exam/etc prevent care. Most just go steadily downhill even if you do good good limb salvage; they just don't take care of themselves. This is why trying PP in low socio-econ area is such a headache and needs such high pt volume (and scammy grafts now not paid) to do ok. You get some high level E&M and inpt billing, but that's not usually the way to do it well in PP.
It's a PP worst nightmare to get called for a no-pay ER gas osteo that needs amp+admit+DPC which has Dr PP missing some office private pay ingrowns, warts, bunion, PF, etc in that same time. The hospital Dr FTE doesn't care about that situation... wRVU are wRVU. If the insurance mix of an area is bad, that's where it makes more sense to be hospital FTE (but that leaves a lot of job quality and $$ on the table in good payer mix area).
...Personally, I'm in a small town and do it all (all foot/ankle path) since that's what the community needs and refer sources send all, but I definitely make more $/hr on elective derm/nail/ortho office than trauma surg ... and much more on that than on wound/amp stuff. Office payers are good. The trauma payers are variable. The wound/amp/pus is the worst payers, sickest pts, many no-pays, most likely to also pull no show or show late or last minute resched, not pay copays, ask for disability papers, show up in ER or office needing admit going into a weekend, etc. Between the low pay and the low challenge and the low compliance and poor outcomes, the wound/amp/pus is not my favorite (and 99% of MDs agree, hence podiatry's very existence in most areas/hospitals).
YMMV
