As you work to keep your patients engaged and loyal, you may run into a costly issue: referral leakage. It’s a common but often overlooked reason why practices lose revenue and why staff may feel discouraged as patients slip away.
Before diving into this article, consider these key stats about referral leakage:
- 55–65% of referrals are sent out-of-network, costing health systems approximately $821,000–$971,000 per physician each year
- Nearly 20 million clinically inappropriate referrals occur annually, often due to a lack of clear information about in-network specialists
- 79% of providers believe in-network care coordination is important, but 8 in 10 still refer out-of-network
- While 91% of providers value access to specialty details, 70% repeatedly refer to the same provider, regardless of the patient’s needs
- Shockingly, 1 in 4 health systems doesn’t track how much revenue is lost due to referral leakage
What Is Referral Leakage?
Referral leakage, which is considered a form of patient leakage across care settings, occurs when patients are referred—or choose to go—to providers outside of your practice’s intended referral network. This can happen either when:
- A provider refers a patient to an out-of-network specialist, or
- A patient independently chooses to seek care elsewhere.
While some leakage is unavoidable, much of it can be managed with the right systems, tools, and communication strategies.
