Transplant
Transplant covers solid-organ procedures, principally kidney and liver, and the immunosuppression and monitoring that follow for the rest of a recipient's life. Transplantation is subject to strict legal rules on donation and allocation, and those rules differ by country. Any programme you consider should be able to explain the source of the organ and the legal framework it operates under, in writing. Equally important is what happens afterwards: lifelong immunosuppression has to be managed by a transplant service in the United States, and that arrangement should be in place before you travel, not after.
Procedures in Transplant

A donor kidney is placed in the iliac fossa with vascular and ureteric anastomoses to treat end-stage kidney disease; the native kidneys are usually left in place.

Major abdominal operation that removes a diseased liver and replaces it with a deceased- or living-donor graft, indicated for end-stage liver disease and acute liver failure.
Frequently asked questions
Does U.S. insurance cover a transplant abroad?
Most U.S. health plans do not pay for elective surgery abroad, and cosmetic procedures are not covered at all. The CDC warns that care for complications after surgery abroad may not be covered either.
