The average cost of office space for an interventional practice is around 5-8% of the collections; billing fees typically range from 5-8%, purchase amortized or lease fees for equipment and maintenance are around 5-10%, staffing costs vary but range from 5-20%, and benefits are usually 8-15%. Therefore overhead is around 50% It appears this offer may be reasonable but it depends largely on what the office space costs are. A couple of local pain docs that got in bed with a couple of OSS ended up paying $75,000 a month as their office space allocation.
An RVU system is primarily for hospitals and anesthesiologists. It doesn't work well in the real world since these values are very difficult to calculate and would require entry of different work types (eg. follow up visits, initial consults, RVUs for each procedure are different, etc) that would probably make it a no go for the company making the offer. The bottom line is that you do have to produce around twice the collections compared to your income, but with appropriate training of the other specialists on what to refer and marketing within the 50 doctor group, you should be able to tailor a very nice interventional practice. The first year guarantee of $300K is very generous since the overall average income for all anesthesiologists is only $309. It will take around 2 months minimum for credentialing in insurance companies and Medicare and the group may have to eat part or all of the charges for some patients during that time (you are out of network and will be paid a reduced rate or zero by insurers). By 4 months collections should reach 65% of the max you will achieve, and by 7 months you will be at max. Doing the math, with a $300K guarantee, the expectation is that your anticipated collections at max will be at least $800K.
The down side: you don't have any guarantee the guys in the group will refer to you, and they may have long standing referral patterns to other docs. The group may pressure the outliers to do so, but they cannot force them. There is not a partnership offer on the table and therefore your referral to their MRI, PT, back brace, and other ancillary services that will be expected of you may not generate any partnership income for you. Without partnership opportunities, you are working year to year only. Finally, there needs to be some designation on what happens if you depart the practice....ie the residual collectables and billings. It is likely the group will want to retain these but this will leave you with zero income on your departure. This is not uncommon, but you may be able to negotiate a percentage of collections that will continue to flow to you for 6 months after departure from the practice. Best of luck with this job. It appears to be a fair offer.
