Before MELLOY, HANSEN, and SMITH, Circuit Judges.
                           ___________

PER CURIAM.

       Allen and Debra Payne appeal the district court’s1 adverse grant of summary
judgment to the United States in this medical malpractice action brought under the
Federal Tort Claims Act, 28 U.S.C. §§ 2671-80 (FTCA). Upon de novo review, see
Meyers v. Neb. Health and Human Servs., 324 F.3d 655, 658-59 (8th Cir. 2003), we
agree that summary judgment was proper, because the undisputed evidence showed
that Allen was or should have been aware of his injury and its cause no later than
April 1, 1991, the date of a letter he sent to the Department of Veterans Affairs (VA),

      1
      The Honorable Nanette K. Laughrey, United States District Judge for the
Western District of Missouri.
seeking increased benefits, see Motley v. United States, 295 F.3d 820, 822 (8th Cir.
2002) (FTCA claim for medical malpractice accrues when plaintiff actually knew, or
in exercise of reasonable diligence should have known, cause and existence of
injury). Even if Allen did not actually know of the probable cause of his injury on
that date, he would have discovered the probable cause in short order if he had
exercised reasonable diligence, and the undisputed evidence showed that he did not.
See United States v. Kubrick, 444 U.S. 111, 123-24 (1979) (plaintiff has
responsibility to seek advice in medical community once aware of harm and cause);
Garza v. United States Bureau of Prisons, 284 F.3d 930, 935 (8th Cir. 2002)
(suspicions of claim give rise to duty to inquire into existence of claim in exercise of
due diligence; determination of whether plaintiff acted reasonably is objective).
Because Allen knew or should have known of his injury and its probable cause more
than two years before January 1999, the Paynes’ January 1999 and March 2000
administrative claims to the VA were untimely, and their action is barred. See 28
U.S.C. § 2401(b) (plaintiffs must file claim with federal agency within 2 years of
accrual of tort claim). We agree with the district court that the Paynes did not show
any basis for equitable tolling.

      Accordingly, we affirm the judgment of the district court.
