Stem cell clinics across the U.S. often say their procedures are legal because they follow what’s called the “same surgical procedure exception.” This idea comes from a regulation that allows cells and tissues to be taken out and put back into the same patient during the same operation—without needing FDA approval.
The original purpose of this rule was pretty specific. For example, if you have fat removed during liposuction and it’s re-injected into your body in the same procedure—without changing it much—that might qualify. But here’s where it gets tricky.
Many clinics stretch the meaning of “same procedure” and “minimal manipulation.” They claim that because the cells come from the patient and go back into the patient, they don’t need FDA approval. Some even use lab processing techniques or store cells temporarily—but still say it’s all part of one procedure.
The FDA Disagrees (At least as of today)
In most cases, the FDA says that processing stem cells in any significant way—especially if it’s done in a lab or if the cells are not returned right away—means the product is now a biological drug. That means it must be approved under more strict regulations (called section 351 products).
So why do clinics keep using this loophole?
Because until recently, there wasn’t much enforcement. Many clinics saw it as a gray area and took advantage of the FDA’s limited oversight power. Some even used this as a business model.
That’s changing now. The FDA is cracking down, and court rulings—like the one involving a Florida clinic using umbilical cord stem cells—are reinforcing the limits of the same surgical procedure exception.
Clinics and patients should both know: Just because a treatment uses your own cells doesn’t mean it’s legal—or safe.
Why it matters to you:
If a therapy isn’t FDA-approved and doesn’t clearly qualify as a 361 product, there may be legal and medical risks involved. Patients should understand classification their treatment falls under—and how the clinic justifies it.
