42 U.S. Code § 11135 - Duty of hospitals to obtain information
With respect to a medical malpractice action, a hospital which does not request information respecting a physician or practitioner as required under subsection (a) of this section is presumed to have knowledge of any information reported under this subchapter to the Secretary with respect to the physician or practitioner.
Each hospital may rely upon information provided to the hospital under this chapter and shall not be held liable for such reliance in the absence of the hospital’s knowledge that the information provided was false.
 So in original. The closing parenthesis probably should not appear.
