Super interesting. Here are my thoughts:
1. I always thought a doctor who made house calls would really bring something unique to the table (as long as everything was done safely) and bring a lot of business and low overhead into their practice.
2. I'd be really interested to see what their take home salaries are like. It seems to me that the cut in overhead is obvious, but I'm not sure if this is balanced out by the fact that they see so many fewer patients. My guess is that it could be close to a wash.
3. I wonder how much of their time they spend doing clerical BS that normally no doc would do because they don't even have a patient coordinator or someone to do billing.
Interesting model for sure. Guess time will tell if it catches on.
I've seen this done at a few private practices. Usually they are small practices with not too many physicians. If your practice is big, then the paperwork as well as losing organizational efficiency gets to be a problem.
Billing and insurance becomes a nightmare -getting the right billing form for various insurnace (state medicaid, medicare, sCHIP, workman comp, blue cross, aetna, cigna, tricare, etc) ... determine the right co-pay. Also you have to submit these bills to insurance companies, keep track of account-receivables, reimbursement denials, etc. Also to submit claims you need appropriate ICD9 codes (and wasting time looking up ICD9 codes*). At the same time you need someone to man the phones, schedule appointments and follow-ups, and also send letters (or phone calls) reminding people about their appointment. Remember, thanks to our legal system, if you don't send a reminder to patients about their appointments (and send certified letters reminding them of their missed appointments) and sometime medically happens to them (injury/death), you can be liable for medical malpractice. Also you need someone to take the phone calls from patients who are sick seeking advice
There's also paperwork associated with insurance - prior authorizations and denials. Again if you don't help your patient appeal a denial, and sometime bad happens to the patient, then you can be liable (but not the insurance company who issued the denial).
In addition, you have to be able to keep track of your cash flow and make sure all the bills are paid on time.
A small practice can get away with this. But I can't see a medium size practice or large group practice getting away with this - there's too many complexities (include physician personal billing code that is difference with each insurance companies)
Now to JaggerPlate's questions,
Home visits - Medicare does reimburse for home visits but the reason why so few doctors do home visits is the opportunity cost involved. In 2005, Medicare will reimburse $110 for a detailed (level 4) home visit. The visit can last 30-45 minutes (but can easily exceed that, especially if you're in a home environment with the patient and start talking about nonmedical stuff, ie life). Physicians that do home visits get a lot of satisfaction out of it. But time wise, each visit (including transportation time) can take an hour or more. For that hour, you could have 3-4 patients (at 15-20 minutes each) in the office - billing level 3 or level 4 for each visit. Basically in that hour, you could have made $110 (plus transportation cost) if you did the home visit, or you could have billed $50-$80 per patient (for a level 3-4 visit) for the 3-4 patients you saw in that hour. The differerences adds up over time.
And for the elderly, they seldom only see one physician (a PCP) but have other specialists involved in their care too. But the physicians that I know who do house calls, they get great personal satisfaction out of it.
