There are a lot of doctors now that don't take insurance, and that you pay on retainer. The phrase you want to google here is "concierge medicine". It's definitely expensive, but not Saudi prince expensive.
Most concierge practices retain the same business model. They ditch insurance, and the billing staff they hired to wrangle the insurance, and reclaim the time they personally spent wrangling insurance.
They then keep roughly the same business model, charging more or less what insurance would have paid them. They spend more time with patients because (a) not on the phone fighting, (b) though the patient pool goes down, they’re replaced by not having to pay for billing staff.
Very very few “concierge” practices aim for any more deviation from the standard business mode than that.
If you want someone to spend 40 minutes with you rather than 15, that’s your guy. If you want someone to spend a week analyzing all your old records and sleuthing it out, that model still doesn’t support it.
