I agree with glade. A surgical group of 4 or more surgeons is getting on the larger side and can have the resources to afford a mid-level. Even here, in a large city, many surgical groups are 3 or fewer surgeons. The "super groups" will often have 1 person who is MIS trained, another CRS, and so on - they clearly have PAs, RNs or NPs on staff.
That being said, my partner has a PA but she is entirely responsible for her salary, as I am able to get my work done without one so am not willing to split the costs. So you have to evaluate the cost-benefit analysis; if a midlevel allows you to spend more time with your family, less time answering calls during the day, less paperwork, then perhaps its worth the cost.
You are right to some extent. Less than 5% of general surgery PAs work in solo practices while more than 10% of ortho PAs for example work in solo practices. The majority of PAs in both general surgery and orthopedics work in either group practices of some type. Bariatrics is also a huge area for surgical PAs right now.
From a reimbursement standpoint there are three ways that surgical PAs bring in income for a practice.
1. First assist fees
2. Office procedures
3. Physician additional downstream revenue.
In orthopedics, these are about equal. Ortho provides lots of in office procedures as well as many surgeries that reimburse for first assist. The downstream revenue is a bit more difficult to quantify but it essentially is productivity by the physician allowed by shifting poorly reimbursed items to the PA. For example if the PA sees followups that are not reimbursed because of the global period this frees up the physician to see more new consults. Consults not only produce the consult fee, but also more procedures and surgeries.
In breast first you have the problem that many surgeries such as lumpectomies do not reimburse for first assist. You also probably don't have many in office procedures to pawn off on the PA. Finally depending on how busy you are you may not have enough business to generate downstream revenue.
You also touch on the reasons for hiring a PA.
1. You are too busy for one provider. You have to be careful here. In surgery you will still have to have a surgeon on call no matter what so if you are really busy with surgery then it may be better to add another surgery. On the other hand if you are backed up with follow ups and can't see new consults then a PA will allow you to see more consults and do more surgery without splitting the number of procedures with another surgeon.
2. You are getting things done but with a significant social cost - ie you are getting home every night at 9pm. In this case unlike the first you are not counting on full reimbursement to offset the cost of the PA. You are essentially paying money to enhance your lifestyle.
3. The third reason if for patient safety. This is most common in academic settings. There are too many patients for the current team to handle but there won't be any more income by adding another provider.
Most cases are some combination of these. Of course in big groups with PAs you also get into issues with "sharing" the PA. YMMV.
