Healthcare fraud investigations rarely start with a dramatic raid. They usually begin with billing or referral patterns that make someone look twice. If you run a practice, manage billing or oversee operations, you need to know which behaviors tend to attract scrutiny. Knowing what they are allows you to fix problems before they escalate.
Here are three warning signs that most often draw attention.
Billing for services not provided
Billing for services that never happened creates immediate legal exposure. If you submit a claim for a visit a patient missed, a procedure you did not perform or a test no one ordered, you create a paper trail that does not match reality. Insurers routinely compare claims data against patient records to find those gaps. Even a few unsupported claims can trigger an audit. Regulators refer to this as “phantom billing” and treat it as fraud.
Inflating or misrepresenting billing codes
Upcoding happens when you bill for a more expensive or complex service than you actually provided. If your claims regularly show higher-level procedures or longer visits without clear support in your notes, reviewers will start asking whether your documentation truly backs up what you billed. One mistake may look like a coding error, but when the same gap between your notes and your billing shows up again and again, it stops looking accidental.
Engaging in improper referral or kickback arrangements
Improper referral arrangements arise when you offer or receive something of value in exchange for patient referrals. Federal law prohibits financial incentives that influence where a patient receives care. Investigators look closely at compensation models that track referral volume instead of legitimate services. If money or benefits flow in a way that depends on how many patients someone sends you, enforcement agencies may view that structure as unlawful.
Address concerns before regulators do
You do not have to wait for a subpoena to take these warning signs seriously. If you notice billing, coding or referral practices that raise concerns, review them now and correct the issue before a routine audit turns into a formal investigation. If you are unsure about your legal risk, get guidance from a health care lawyer. A proactive step today can protect your practice tomorrow.
