Are doctors violating the hippocratic oath, when they do not treat patients without money?

No.

The Hippocratic Oath does not require free treatment.

First, doctors don't have to take the oath. Second, the oath has no legal effect and is not law. For example, it is against abortion, which obviously doctors do. It also says they will support for life the person who taught them. It also talks about never using the knife, which leaves all doctors who do surgery out.

They have changed the oath for modern times, but neither include a requirement to treat people for free.

Why do people think professionals like lawyers and doctors should work for free? You don't expect anyone else to.

Harley, wow, three ignorant posts in a row. Operations are NOT cheap. You have the OR, the nurses, the anesthesiologists, the doctors time (where he could be earning money), the hospital, the aftercare. That's why we need the ACA, so that everyone can get the treatment they need. But you apparently think small businesses (doctors) should pick up the slack instead of wealthy corporations (insurance companies and businesses that should insure their employees.)

No the Hippocratic oath does not say anything about treating people for free.

The spirit of the Hippocratic Oath is that they will do no harm. It doesn't say anything about supplying medicine and care for free.

@Harley You do realize that medical care isn't cost-free for the supplier, right?

No

If a doctor wont treat someone, then by definition that person is not their patient.

how any "doctor" can turn away a person in suffering when an easy cheap operation could cure them is beyond me the gouging that goes on in the medical profession borders on the criminal, dentists and vets have also joined in

Yes. They should be imprisoned and deported to Siberia.
