Primary care physicians (PCP) have struggled to maintain their compensation levels, settling in at a modest $150,000-$160,000 annually. PCPs' low wages are the result of declining reimbursements which are resulting in profits dwindling to the point at which the average practice has a mere 10%-15% margin of wiggle room. Many PCPs focus their attention on declining Medicare and third-party payer reimbursements, but these may be the least of their concerns, with new retail clinics-small, kiosk-type clinics usually located in high-traffic retails stores such as Wal-Mart®, Target®, or CVS®-are likely to deliver a swifter, harsher blow to yet another area of the primary care revenue stream.
