Well then no hospital based group will hire you nor any reference lab. And like I sort of explained you won't be able to charge seniors fee for service. The federal govt has some law that limits the max you can charge geezers. It says in effect "If we only give you 30 for an 88305, then you can only charge them 35 if you opt out of medicare" or something like that. In other words you can't bilk geezers. And to make it worse, I believe the govt gives the medicare rate to the patient and then you have to go try to collect it from the patient, and the geezer is probably saying "Screw it, I am going to die anyway, so I'll just keep the $30. Screw that pathologist guy, who the hell is he anyway. I never saw no Dr. Nilf. Is he even a real doctor? Don't pathologists just do autopsies and solve crimes".
You could try to start your own path lab and take only outpatient stuff and send out the medicare cases.
Or you could go into pediatric pathology.
