Great question and the most important thing to sort out first is actually pretty simple.

Is this lien against the person or against the property?

Medical and hospital liens in Florida are almost always against the person, not the real estate. They are typically meant to attach to any insurance settlement or personal injury recovery the patient receives, not to their house.

For a lien to actually stick to real property and survive a foreclosure, there needs to be a clear legal connection between the debt and the property itself. A hospital bill has zero connection to someone's home. The patient did not mortgage their house to pay for their surgery.

On top of that, even for a property related lien to be enforceable against a future buyer, it needs to have been properly recorded as a duly recorded instrument in the county public records before the foreclosure sale. That means the debtor would have had to actually sign something giving the hospital a security interest in the property, and that document would need to be on record as constructive notice. A hospital simply filing a lien claim does not come close to meeting that standard.

And if the hospital was not even named as a defendant in the foreclosure action, that is another major problem for them, not for the buyer.

Bottom line: the new owner almost certainly has nothing to worry about here. This looks like a personal debt of the former owner, not an encumbrance on the property. A title attorney can confirm it with a quick look at what was actually recorded, or more likely, what was not.

I am not an attorney and nothing I share here should be taken as legal advice. Every situation has its own facts and nuances, so I always recommend consulting with a qualified real estate or title attorney before making any decisions.

Fernando is more of an expert than me, but the key is homestead. I put my answer into AI and had it fluff it out for you:

There are two different types of documents a hospital might record:
A Statutory Hospital Lien: As established above, this only targets personal injury settlements. Homestead status is irrelevant because the lien cannot attach to real estate anyway.

A Certified Civil Judgment: If the hospital sued the former homeowner for the unpaid medical debt, won the lawsuit, and recorded a certified copy of the final civil judgment, that judgment can act as a lien against real estate.

This is where Homestead changes everything.

Article X, Section 4 of the Florida Constitution provides one of the strongest homestead protections in the country. If the foreclosed property was the prior owner's primary residence (homestead), no judgment creditor, including a hospital or credit card company, can attach a lien to it or force its sale.

If it was their homestead: The hospital's judgment lien is completely invalid against the property. The new buyer takes title free and clear.

If it was an investment property (non-homestead): The recorded civil judgment would attach to the real estate. In that specific scenario, if the hospital was omitted from the foreclosure suit, the judgment lien would survive the sale and cloud the new buyer's title.

Statutes & Constitution
Fernando gave excellent guidance. A standard hospital lien is a personal debt issue, not a property encumbrance. A title attorney looking at the actual recorded document can confirm whether it is just a statutory hospital lien (no threat to the property) or a civil judgment (a potential threat only if the property was non-homestead).
