It's not quite PE (yet); doctors are getting annoyed themselves at how healthcare is playing out. Picture things like electronically messaging your doctor now has convoluted billing behind each conversation now based on the level of effort the doctor has to put in. They're getting annoyed now that they've been bought out by hospital systems and been working underneath them for a while doing family practices and other healthcare services. The paychecks were good, but the red tape got annoying over the years.
So they exit the whole system and go to a direct "you pay me monthly for access" model. Hundred bucks a person or so per month, factor a ~25% discount for families. Doc gets to keep a cap on the limit of incoming patients to manage their own day pretty nicely while getting a recurring stream of cash paid direct to him.
Even better if your wife's also a doctor (hey, healthcare partners run together a lot!), you just band together, see 5-600 patients a month as a couple, and pull in a decent $million or so on a fairly light workload and selling extra things like GLP-1s and wellness programs for a year's work. Triple-points if you're doing this in rural America - that million might not be a lot to the big techies out there, but that's big bucks that go far in some really nice places tucked away in the trees and forests.
You still need insurance for the rest of the 'stuff' they don't do, but some of these DPCs are doing everything they can in house (like prescribing and dispensing generics at the office directly in a single visit to lower your extra out of pocket costs).
If you're on a high deductible healthcare plan with an HSA and an employer contributing healthily into it, these direct-patient-care clinics may be an attractive option if you're reasonably healthy and young.
