Common Mistakes to Avoid
- 1
Not starting Medicare credentialing immediately — a 6-month delay costs $50,000-$100,000 in lost revenue
- 2
Underestimating the importance of physician referral relationships — build MD relationships before opening
- 3
Not hiring a physician liaison or dedicating time to referral marketing
- 4
Overrelying on a single referral source — losing one surgeon or orthopedist can eliminate 30% of revenue
- 5
Insufficient working capital — PT reimbursement averaging $150-$300/visit with 30-90 day payment delay creates cash flow challenges
