That's a difficult question to answer, since there are a lot of different views/theories regarding this issue.
Some believe you can open your office with just one treatment chair until you get busy enough to purchase/lease a second, and some believe it's mandatory to start off with two from the start.
Some believe you should rent space large enough from the start to accommodate your anticipated growth, and other's believe that means you're spending too much money in the beginning that you can't afford. They believe you should sign a relatively short term lease and move to a bigger space as you grow.
Most new docs purchase their big items on a lease/purchase arrangement, which means you pay X amount of dollars for X amount of years, similar to a car payment. At the end of the last year, the equipment is yours for a nominal final payment. If that is too costly, bank loans accomplish the same thing.
As far as staff goes, I believe in being a "minimalist" in the beginning and not trying to overspend. Don't try to impress everyone with too many staff that you can't afford.
Additionally, since it's YOUR office, it's also my opinion that YOU should know EVERYTHING about your office, and not simply delegate chores. YOU should know how to bill. YOU should know the ins and outs of insurance issues. YOU should know how to take and develop an x-ray. YOU should know how to order supplies. YOU should know how to pay all the bills. YOU should know the numbers of the insurance companies. YOU should know the numbers of the utility companies if your phones don't work, your heat doesn't work, your electricity doesn't work, etc. YOU should know how to call the hospital to schedule a surgery.
I think you get my point. The reason for this is because someday you will come to the office on a busy day and a key member of your staff will not show up due to illness, irresponsibility or some goofy reason.
And the show still must go on, and YOU are the captain of the ship. When I opened my office and it started getting extremely busy, my office manager who THOUGHT she was the only one who knew how to do the billing, etc., became extemely ill and was out for 4 months. I was too busy to realize that NO ONE else in the office was ever taught how to do the billing.
Fortunately, I knew how to do it, so at nights and on weekends for 4 months (I didn't have time to teach my other staff) I did the billing myself.
APMA dues presently are about $1600-$1700 a year which includes state dues. (I'm not sure about first year rates). The American College of Foot & Ankle Surgeon dues are presently $550 a year and I believe that dues for the American Board of Podiatric Surgery are about "$500.
You must also add in state licensing fees which vary from state to state, but can be costly, because some have 3 year renewals. Additionally, there are DEA registration fees which also can be costly for a 2-3 year renewal (several hundred dollars). Some states such as NJ also require an additional CDS license, which is relatively inexpensive. Most hospitals also require an application fee of several hundred dollars just to APPLY for privileges and most hospitals also require "staff dues" of several hundred dollars every year or two.
One of the most difficult parts, which is free, but frustrating and time consuming, is contacting all the insurance companies and getting on the insurance "panels". That can take months and a lot of red tape. And naturally, it's difficult to treat patients without the ability to bill insurance.
Another consideration will be a computer/software system for your office, which can be one of your biggest expenses.
Purchasing an x-ray unit may be your single largest expense. Some young doctors are opting not to invest in this equipment initially, if they are close to a free standing x-ray facility or hospital. With capitated insurance plans, we can often NOT get paid for taking x-rays, and those plans are getting more popular in some areas. Additionally, in some areas some insurance companies are "contracted" with specific radiology sites for x-rays, therefore you can't take them in your office.
I just read that in NJ, one of the largest insurers in that state is proposing that they will no longer pay DPM's or other specialists to take x-rays in the office. All x-rays must be performed at approved facilities.
So you must weigh whether your expense is worth the investment. Especially when considering that most docs are no longer purchasing simple x-ray machines and processors, but are now going digital, which is a VERY large expense.
I can recommend a few sources that will probably be able to give you actually "numbers" and speak with you about actually setting up an office.
I would contact a rep at one of the podiatry suppliers such as Surgical Supply Service (if you need the number, let me know) or Gill Podiatry Supply. And I would DEFINITELY contact the American Academy of Podiatric Practice Management. This is right up their alley.
