In some areas of the country, the shortage of primary-care providers is ever more acute. You can have gold-plated insurance or pay cash, but you cannot find a family practitioner, internist, pediatrician or ob/gyn to see you because their practices are full. You can only take care of so many patients and do a decent job and still have a life away from the office.
If you live in a large urban or suburban area, you can still find largely find care, since this is where primary-care physicians like to practice. In smaller urban, suburban or especially rural areas, the shortage is getting worse. If some sort of national mandate regarding healthcare insurance is passed into law, that is all well and good, but it will not increase the supply of providers. Massachusetts is an excellent example of this. Now everyone in Massachusetts has state-mandated health insurance, but the reimbursement rates from the state insurance are low, and there are just not enough physicians to see everyone. Waiting times of several weeks or months for non-urgent care are common.
