Midland Psychiatric Associates, Inc. (Midland) appeals the district court’s two-pronged order dismissing Midland’s lawsuit against the United States and Mutual of Omaha Insurance Company (Mutual) for lack of subject matter jurisdiction. See Fed.R.Civ.P. 12(b)(1). The district court held Midland’s tortious interference with contract claim against Mutual, and Midland’s Federal Tort Claims Act (FTCA) negligent supervision claim against the United States, were juris-dictionally barred by 42 U.S.C. §§ 405(h) and 1395Ü. The district court also dismissed Midland’s claim against Mutual based on common-law official immunity. We affirm.
Like the district court, we take our statement of the facts from Midland’s complaint, but we supplement the complaint with the district court’s findings where the complaint is silent on jurisdictionally significant facts. Under contracts with two Kansas City area hospitals, Midland provided partial hospitalization services to nursing-home residents. Partial hospitalization is an intensive outpatient service covered under Part B of the Medicare Act. See 42 U.S.C. §§ 1395k(a)(2)(J), 1395x(ff) (1994). Part B *1002 claims are processed by Medicare carriers— chiefly insurance companies, see id. § 1395u(f) — under contract with and on behalf of the Department of Health and Human Services. See id. § 1395u(a). Midland billed the hospitals, and the hospitals in turn submitted Medicare claims for Midland’s services to Mutual, a Medicare carrier.
Mutual denied thousands of the hospitals’ Midland-related claims on the grounds that Midland’s services were unsupervised by a physician and medically unnecessary.
See id.
§§ 1395x(ff)(l), (2). Midland contends Mutual denied the claims to put Midland out of business. According to the district court, the hospitals sought administrative review of Mutual’s claims denials,
see Midland Psychiatric Assocs., Inc. v. United States,
Like the district court, we begin our analysis with the Missouri law governing Midland’s diversity-based tortious interference with contract claim. Under that law, Midland would have to prove, among other elements, that Mutual interfered with Midland’s hospital contracts without justification.
See Rice v. Hodapp,
The district court also concluded 42 U.S.C. § 405(h) deprived it of the power to conduct such a review. See id. at 547-50. Section 405(h) is a provision of the Social Security Act made applicable to the Medicare Act by 42 U.S.C. § 1395Ü. As modified by § 1395Ü for Medicare Act purposes, § 405(h) reads:
The findings and decision of the [Secretary of Health and Human Services] after a hearing shall be binding upon all individuals who were parties to such hearing. No findings of fact or decision of the [Secretary] shall be reviewed by any person, tribunal, or governmental agency except as herein provided. No action against the United States,'the [Secretary], or any officer or employee thereof shall be brought under section 1331 or 1346 of title 28 to recover on any claim arising under this subchapter.
The district court held § 405(h) barred Midland’s tortious interference claim in two distinct ways. First, because Midland failed to exhaust administrative remedies, its claim was barred by sentence two of § 405(h).

As the district court noted,
see Midland,
*1003
U.S.C. § 405, particularly § 405(g),
see Illinois Council on Long Term Care Inc. v. Shalala,
The burden of establishing that federal jurisdiction exists “rests upon the party asserting jurisdiction.”
Kokkonen v. Guardian Life Ins. Co. of Am.,
Midland argued below, and argues on appeal, that its claim does not fall within the scope of § 405(h)’s third sentence: “No action against the United States, the [Secretary], or any officer or employee thereof shall be brought under section 1331 or 1346 of title 28 to recover on any claim arising under this subchapter.” To decide if Midland is correct, we must determine whether, as a matter of law, (1) Mutual is an officer or employee of the United States, (2) sentence three bars diversity-based claims as well as those brought under federal-question jurisdiction (§ 1331) or the jurisdictional statute for suits against the United States (§ 1346), and (3) Midland’s tortious interference claim arises under the Medicare Act. We consider these issues in turn.
The district court first concluded that as a Medicare carrier, Mutual is an officer or employee of the United States.
See Midland,
Second, the district court concluded that despite its literal wording, sentence three of § 405(h) bars claims based on diversity of citizenship under 28 U.S.C. § 1332, the jurisdictional basis of Midland’s claim against Mutual.
See Midland,
This conclusion is not in disagreement with our decision in
Rochester Methodist Hosp. v. Travelers Ins. Co.,
Third, the district court concluded Midland’s tortious interference claim arises under the Medicare Act.
See Midland,
We take up next the district court’s last alternative basis for dismissing Midland’s claim against Mutual: the federal common-law doctrine of official immunity. Under Westfall
v. Erwin,
Despite the changes wrought by the Westfall Act, it is well established that
West-fall
still articulates the more restrictive federal common-law rule 'limiting official immunity to discretionary conduct.
See Beebe v. Washington Metro. Area Transit Auth.,
Before we conclude our analysis, however, the Supreme Court directs us to consider whether providing immunity would potentially do more harm than good.
See Westfall,
Finally, we turn briefly to the • district court’s dismissal of Midland’s FTCA claim brought against the United States under 28 U.S.C. § 1346. According to Midland’s complaint,, the Government is liable to Midland for negligent supervision because it allowed Mutual to deny Medicare claims wrongfully. As the district court points out, “[t]he Government’s liability is ... derivative; it depends upon a showing that the entity the Government was supposed to supervise— Mutual — acted tortiously.”
Midland,
We affirm the district court’s dismissal of Midland’s claims for lack of subject matter jurisdiction.
