Is FTCA the exclusive remedy for a tort claim for personal injury or death resulting from the performance of a self-determination contract?

Yes, except as explained in § 900.183(b). No claim may be filed against a self-determination contractor or employee for personal injury or death arising from the performance of medical, surgical, dental, or related functions by the contractor in carrying out self-determination contracts under the Act. Related functions include services such as those provided by nurses, laboratory and x-ray technicians, emergency medical technicians and other health care providers including psychologists and social workers. All such claims shall be filed against the United States and are subject to the limitations and restrictions of the FTCA.
