OPINION
Nichole Medical Equipment and Supply Company (“Nichole Medical”) appeals the district court’s dismissal of an action that Nichole Medical brought to recover damages for various state and federal claims. The district court dismissed the suit for lack of subject matter jurisdiction and because Nichole Medical had not stated a claim for which relief could be granted. For reasons that follow, we agree. We also agree that all of Nichole Medical’s claims arise under the Medicare Act and that the Defendants/Appellees are therefore immune from suit as officers or employees of the Secretary of the Department of Health and Human Services. Accordingly, we will affirm the district court’s dismissal of the complaint.
I. Statutory and Regulatory Background
This suit originates from relationships that were created under the Medicare Act, 42 U.S.C. § 1395 et seq., (“Act”). The Act is administered through private organizations that contract with the Secretary of the Department of Health and Human Services.1 30 Fed. Proc. § 71:746. Pursuant to statutory provisions in effect prior to October 1, 2005, Medicare Part B was administered by organizations known as “carriers.”2 Id. Carriers entered into contracts with the Centers for Medicare and Medicaid Services (“CMS”). The obligations undertaken by carriers under those contracts include paying for items Medicare suppliers provide to Medicare beneficiaries, adjusting any incorrect payments, and recovering overpayments when the carrier concludes an overpayment was made for a covered Medicare benefit. 42 C.F.R. §§ 421.100, 421.200; see also 30 Fed. Proc. §§ 71:747, 71:754.
As a result of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, the obligations previously imposed on carriers are now undertaken by Medicare Administrative Contractors (“MACs”). See Medicare Prescription Drug, Improvement, and Modernization Act of 2003, Pub.L. No. 108-173, § 911(e), 117 Stat.2066, 2256 (2003).3 MACS enter *343into contracts with CMS to perform various duties pursuant to 42 U.S.C. § 1395kk-l. 42 U.S.C. § 1395kk-l; see also 42 C.F.R. § 421.401. Those duties include assisting in the administration of the Medicare Integrity Program. 42 U.S.C. § 1395kk-l; see also, 30 Fed. Proc. § 71:746.
Pursuant to the Medicare Integrity Program, entities known as “Program Safeguard Contractors” (“PSCs”) contract with CMS to perform various program integrity tasks to “safeguard” Medicare payments on behalf of the Secretary. See 42 U.S.C. § 1395ddd(a). PSCs responsibilities include reviewing Medicare payments for potential fraud and ensuring that amounts billed under the Medicare program are appropriate and supported by proper documentation. See 42 U.S.C. § 1395ddd(b).
This auditing obligation thus requires MACs and PSCs to determine if amounts paid under Medicare “are reasonable and necessary in accordance with Medicare coverage policies and program instructions.” 42 C.F.R. § 421.500. In discharging this obligation, CMS or a Medicare contractor can suspend payments under the Act in whole or in part “if CMS or the Medicare contractor possesses reliable information that an overpayment existed or that the payments to be made may not be correct, although additional information may be needed for a determination.”4 42 C.F.R. § 405.371(a)(1) (emphasis added). A Medicare contractor is also authorized to offset or recoup Medicare payments, in whole or in part, if it is “determined that the provider or supplier to whom payments are to be made has been overpaid.” 42 C.F.R. § 405.371(a)(3) (emphasis added).
At all times relevant to our inquiry, Nichole Medical was a durable medical equipment supplier,5 National Heritage Insurance Company (“NHIC”) was a carrier and/or a MAC6 and TriCenturion was a PSC. See 42 U.S.C. § 1395u.
II. Factual Background
This dispute arises from an audit TriCenturion conducted of Nichole Medical’s in the course of TriCenturion discharging its obligations under the Act as a PSC. After examining records obtained from Nichole Medical’s office, TriCenturion concluded that Nichole Medical “might” be improperly billing Medicare for medical equipment such as the motorized wheelchairs and hospital beds that Nichole Medical provided to Medicare beneficiaries. TriCenturion’s examination of Nichole Medical’s records also caused TriCenturion to conclude that Nichole Medical had received overpayments from Medicare. *344Id. at p. 00007, ¶ 26.7 TriCenturion also concluded that Nichole Medical had not maintained sufficient medical records to establish the reasonableness and/or medical necessity of some of the medical equipment it had supplied to Medicare beneficiaries. Id. at 00037.
Accordingly, TriCenturion directed Nichole Medical’s prior carrier, HealthNow, to withhold payments to Nichole Medical in an effort to recoup the amount that TriCenturion believed had been overpaid to Nichole Medical. Id. at 00007, ¶27. TriCenturion determined the offset amount by calculating the actual overpayment of several specific claims. It then used those claims as a representative sampling of Nichole Medical’s claims and extrapolated an overpayment amount for all of Nichole Medical’s x-elevant claims from that sample. Id. at 00019.
In addition to the offset, TriCenturion also informed the Attorney General’s Office that Nichole Medical had improperly requested reimbursement for certain medical devices delivered to Medicare beneficiaries to fill their prescriptions. TriCenturion persisted in its belief that payments had been improperly made to Nichole Medical even after the Attorney General found no evidence of fraud and refused to prosecute. Id. at 00006, ¶ 23.
For reasons that remain unclear, but presumably because the Attorney General refused to prosecute, HealthNow stopped withholding payments to Nichole Medical and did not attempt to recoup any further payments. Id. at 00066. However, after NHIC succeeded HealthNow, TriCenturion instructed NHIC to re-institute the offset. Id. According to Nichole Medical, reinstituting the offset eventually forced it out of business. Id. Nevertheless, after it went out of business, Nichole Medical pursued an appeal of TriCenturion’s determination that it (Nichole Medical) had been overpaid.8
The administrative law judge who was handling that appeal subsequently determined that Nichole Medical was entitled to reimbursement on some of the appealed claims for which payment had been withheld or offset, but not all such claims.9 Id. at 00035. The ALJ also ruled that TriCenturion had failed to: (i) provide proper notice of the post-payment audit; (ii) establish new evidence justifying the post-payment audit; and (in) fully explain the methodology used for the statistical sampling that resulted in the determination *345that Nichole Medical had been overpaid or improperly paid under the Act. Id. at 00035-55. The ALJ found that the extrapolated amount determined by examining the 39 claims that were sampled had no legal force because it was impossible to recalculate the sampling. Id. at 00054-6.10
The Medicare Appeals Council (“Council”) reviewed the ALJ’s decision and found that the ALJ had erred in determining which of the 39 claims was properly paid because all 39 claims had been reopened and reviewed improperly. Id. at 00018-25.
After the Council entered that ruling, Nichole Medical filed this suit against TriCenturion and NHIC alleging that TriCenturion had wrongfully withheld Medicare payments owed to Nichole Medical for equipment it had supplied to Medicare beneficiaries and that that caused Nichole Medical’s insolvency. Id. at 00007. Nichole Medical also claimed that “TriCenturion conducted an unannounced, unauthorized and illegal search and seizure of Nichole Medical’s Medicare records” when it audited Nichole Medical’s cost reports and records.11 Appx., p. 00006, ¶ 21.
According to Nichole Medical’s allegations, it was forced into insolvency because TriCenturion “developed and implemented a business pattern and practice of ignoring and failing to follow statutory and regulatory guidelines and procedures with regard to its audit activities.” Id. at 00009, ¶¶ 37, 40. Nichole Medical asked the district court to award compensation “including, but not limited to, past and future damages of an economic nature, including: attorneys fees, costs, loss of sales, loss of revenue, loss of profits, and other expenses.” Id. at ¶43. Nichole Medical bases its claim for damages on various state law torts and breach of the statutory duty of care pursuant to 42 U.S.C. § 1320c-6(b).12 Id. at 00065.
The district court granted a motion to dismiss based on Nichole Medical’s failure to exhaust its claims before the ALJ and the Council as required by the Act. Id. at 00070-77. Alternatively, the district court concluded that the complaint should be dismissed because the challenged conduct was within the scope of TriCenturion’s and NHIC’s official duties under the Act and that they were therefore immune from suit under the Medicare Act.13 Id. at 00070-77.
This appeal followed.
*346III. Discussion
A. Jurisdiction
1. Judicial Review under the Act.
42 U.S.C. § 405(h) is incorporated into the Act pursuant to 42 U.S.C. § 1395Ü. Section 405(h) provides
[t]he findings and decision of the [Secretary] 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 134.6 of Title 28 to recover on any claim arising under this sub-chapter.
Id. (emphasis added). Section 405(h) thus limits judicial review of claims “arising under” the Act. See Midland Psychiatric Assocs., Inc. v. United States, 145 F.3d 1000, 1002-3 (8th Cir.1998). In Midland Psychiatric Associates, Inc., the Eighth Circuit explained: “the last four words of § 405(h)’s second sentence — ‘except as herein provided’ — refer to the rest of 42 U.S.C. § 405, particularly § 405(g).... ” Id. (internal citations omitted). Section 405(g) provides that
[a]ny individual, after any final decision of the Commissioner [is] ... made after a hearing to which he was a party, irrespective of the amount in controversy, may obtain a review of such decision by a civil action commenced within sixty days after the mailing to him of notice of such decision____The court shall have power to enter, upon the pleadings and transcript of the record, a judgment affirming, modifying, or reversing the decision of the Commissioner of Social Security, with or without remanding the cause for a rehearing.
Id. at § 405(g) (emphasis added). “Section 405(h) purports to make exclusive the judicial review method set forth in § 405(g).” Shalala v. Illinois Council on Long Term Care, Inc., 529 U.S. 1, 10, 120 S.Ct. 1084, 146 L.Ed.2d 1 (2000). We have previously explained that: “there is no judicial review of final agency action under the district court’s federal question jurisdiction [under the Act].” Fanning v. United States, 346 F.3d 386, 402 (3d Cir. 2003).
Nichole Medical argues that Congress only intended § 405(h) to bar federal jurisdiction of suits under 28 U.S.C. §§ 1331 and 1346 and, therefore, its suit against TriCenturion and NHIC was improperly dismissed because the court had diversity jurisdiction under 42 U.S.C. § 1332.
When it was originally enacted, however, § 405(h) barred virtually all grants of jurisdiction under Title 28. Subsequent “technical corrections” were made in 1976, which resulted in the current wording of that section. We agree that the language may at first appear to bar only jurisdiction under §§ 1331 or 1346 of Title 28. However, it is clear that the changes enacted in 1976 were intended only as “technical corrections” and they were therefore not intended to make any substantive change in the statute. See Bodimetric Health Services, Inc. v. Aetna Life & Casualty, 903 F.2d 480, 488 (7th Cir.1990). Accordingly, we hold that § 405(h) continues to bar *347virtually all grants of jurisdiction under Title 28.
In Bodimetric, the Seventh Circuit explained: “In this section, Congress clearly expressed its intent not to alter the substantive scope of section 405(h). Because the previous version of section 405(h) precluded judicial review of diversity actions, so too must newly revised section 405(h) bar these actions. Any other interpretation would contravene section 2664(b) by ‘changing or affecting a right, liability, status, or interpretation’ of section 405(h) that existed before the Technical Corrections were enacted.” 903 F.2d. at 489 (quoting Griffin v. Oceanic Contractors, Inc., 458 U.S. 564, 571, 102 S.Ct. 3245, 73 L.Ed.2d 973 (1982)). Similarly, in Midland Psychiatric Associates, the Court of Appeals for the Eighth Circuit found “the jurisdictional bar imposed by sentence three of § 405(h) extends to claims based on diversity of citizenship” because “[w]hen Congress revised sentence three, it labeled the amendment a technical correction, and at the same time made clear that no substantive change in the law was intended.” 145 F.3d at 1004.
We therefore agree with the district court’s conclusion that Nichole Medical’s attempt to rely on the court’s diversity jurisdiction by filing under § 1332 is barred by § 405(h) if those claims “arise under” the Medicare Act. Congress clearly prohibited federal courts from exercising subject matter jurisdiction or diversity jurisdiction over claims arising under the Act.
2. Nichole Medical’s Claims Arise “under the Act.”
We exercise plenary review over the district court’s dismissal of a complaint for lack of subject matter jurisdiction. Gould Electronics Inc. v. United States, 220 F.3d 169, 176 (3d Cir.2000). In reviewing a facial attack to the court’s jurisdiction, “courts must only consider the allegations of the complaint and documents referenced therein and attached thereto, in the light most favorable to the plaintiff.” Id. Moreover, Nichole Medical carries the burden of convincing us that Congress has not barred federal courts from exercising subject matter jurisdiction over this suit.
Nichole Medical’s claims for damages are supported by allegations that the defendants: (i) wrongfully entered Nichole Medical’s premises to review its records; (ii) improperly withheld payments to offset purported overpayments; and (iii) unnecessarily informed the CMS of their concerns with Nichole Medical’s billing practices. Appellant’s Brief, pp. 10-16. Despite those allegations and their relationship to Medicare, Nichole Medical argues that its claims do not arise under the Act because it is not asking a court to determine “whether Medicare should pay the claims as submitted, how much should be paid, or whether the [Appellees’] conduct was illegal, wrongful or improper” and “at bottom [it is] not seeking to recover benefits” but rather it is seeking damages arising from Appellees’ “unlawful” conduct.14 Id. Of course, that argument totally ignores the underlying reality that *348all of the actions complained of are squarely rooted in, and arise from, the relationship between the parties. That relationship is firmly rooted in the Act and certainly arises from it.
In attempting to argue the contrary proposition, Nichole Medical relies on Ardary v. Aetna Health Plans of Southern California, Inc., 98 F.3d 496 (9th Cir. 1996), wherein the Court of Appeals for the Ninth Circuit found state law claims did not arise under the Act because, at bottom, they were not seeking to recover benefits. See Appellant’s Brief, pp. 15-16. However, that case involved a wrongful death action and the court merely concluded that the Act did not preclude the heirs of a deceased Medicare beneficiary from bringing state law claims for wrongful death against a private Medicare provider. See Ardary, 98 F.3d at 498. The plaintiffs there were seeking compensatory and punitive damages on the grounds that the Medicare provider improperly denied emergency medical services and misrepresented its managed care plan. Id.
Moreover, the Court of Appeals for the Ninth Circuit subsequently clarified the limited nature of the holding in Ardary by explaining that it “does not extend beyond patients and torts committed in the sale or provision of medical services.” Kaiser v. Blue Cross of Cal., 347 F.3d 1107, 1113 (9th Cir.2003). That is simply not this case.
The Supreme Court has defined claims that “arise under” the Act as claims that are “inextricably intertwined” with a claim for benefits or claims where “both the standing and the substantive basis for presentation” is the Act. Shalala, 529 U.S. at 12, 120 S.Ct. 1084. A claim is “inextricably intertwined” if it does not involve issues separate from the party’s claim that it is entitled to benefits and/or if those claims are not completely separate from its substantive claim to benefits. See Cathedral Rock of North College v. Shalala, 223 F.3d 354, 363 (6th Cir.2000).
A claim can arise under the Medicare Act even if the substantive relief sought is not permitted by the Act. See Heckler v. Ringer, 466 U.S. 602, 623, 104 S.Ct. 2013, 80 L.Ed.2d 622 (1984). As the Ninth Circuit explained in Kaiser, “[t]he fact that [Appellant] seek[s] damages beyond the reimbursement payments available under Medicare does not exclude the possibility that [its] case arises under Medicare. Simply put, the type of remedy sought is not strongly probative of whether a claim falls under § 405(h).” 347 F.3d at 1112.
Bodimetric Health Services, Inc. v. Aetna Life & Casualty is illustrative of this point and “on all fours” with Nichole Medical’s attempt to argue that its claims do not “arise under” the Act. There, a Medicare intermediary refused to pay certain claims and, as a result, Bodimetric went out of business. Bodimetric, 903 F.2d 480, 482-83 (7th Cir.1990). Bodimetric sued the intermediary for fraud, fraudulent concealment, breach of contractual relationship, tortious breach of the implied covenant of good faith and fair dealing and intentional harm to property interest. Id. The Court of Appeals for the Seventh Circuit rejected Bodimetric’s assertion that its tort claims did not arise under the Act. The court explained: a “party cannot avoid the Medicare Act’s jurisdictional bar simply by styling its attack as a claim for collateral damages instead of a challenge to the underlying denial of benefits.” Id. at 487 (“If litigants who have been denied benefits could routinely obtain judicial review of these decisions by recharacterizing their claims under state and federal causes of action, the Medicare Act’s goal of limited judicial review for a substantial number *349of claims would be severely undermined”). We agree.
Here, based on its own recitation of facts, it is clear that Nichole Medical’s action is, at bottom, nothing more than an argument that it was entitled to payments under the Medicare program, those payments were delayed or denied, and Nichole Medical suffered damages as a result. Thus, these claims are not only “inextricably intertwined” with Nichole Medical’s claim for benefits, they derive from (and are firmly rooted in) the Act. See, e.g. Midland Psychiatric Assocs., Inc., 145 F.3d at 1005 (finding a tortious interference claim to be “inextricably intertwined” with a Medicare benefits determination because “[a]t bottom, [Appellant] is claiming [the Medicare carrier] should have paid for its services.”); Bodimetric, 903 F.2d at 486 (“[Appellant’s] grievance is, at bottom, a challenge to [the intermediary’s] approach to processing claims. Judicial review of such a challenge seems to be foreclosed.”); Fanning, 346 F.3d at 400 (It is “apparent that both the standing and the substantive basis for the claim ... are rooted in, and derived from, the Medicare Act” when the claim was wholly dependent on whether the parties qualified as a primary plan as defined by the Act).
3. Judicial Review of Nichole Medical’s Claims
Nichole Medical concedes that it did not raise the tort and contract claims that this suit is based on during its Medicare appeals process.15 To obtain judicial review under § 405(g), however, Nichole Medical “must have complied with (1) a nonwaivable requirement of presentation of any claim to the Secretary, and (2) a requirement of exhaustion of administrative review, which the Secretary may waive.” Cathedral Rock, 223 F.3d at 359 (emphasis added); see also Ringer, 466 U.S. at 617, 104 S.Ct. 2013 (“[T]he exhaustion requirement of § 405(g) consists of a nonwaivable requirement that a ‘claim for benefits shall have been presented to the Secretary’ and a waivable requirement that the administrative remedies prescribed by the Secretary be pursued fully by the claimant.”) (internal citations omitted). “ ‘[A]ll aspects of [Nichole Medical’s] claim for benefits should be channeled first into the administrative process which Congress provided for the determination of claims for benefits.’ ” Fanning, 346 F.3d at 395 (quoting Ringer, 466 U.S. at 614, 104 S.Ct. 2013).
Moreover, Nichole Medical is not exempt from this exhaustion requirement simply because the claims arising under the Act are not within the jurisdiction of the Secretary. See Salfi, 422 U.S. at 765, 95 S.Ct. 2457 (“Plainly [the purposes for exhaustion] have been served once the Secretary has satisfied himself that the only issue is the constitutionality of a statutory requirement, a matter which is beyond his jurisdiction to determine, and that the claim is neither otherwise invalid nor cognizable under a different section of the Act.”).16
*350To conclude otherwise would allow any party to avoid the Act’s administrative procedures for reviewing the Secretary’s determinations simply by restyling their argument as something different. See Cathedral Rock, 223 F.3d at 363. Accordingly, Nichole Medical improperly advances an action based on unexhausted claims that “arise under” the' Act. See Kaiser, 347 F.3d at 1116 n. 4 (9th Cir.2003) (“[A]ll inextricably intertwined claims must first be raised in an administrative process. In that process, the agency, with the benefit of its experience and expertise, can resolve whatever issues it can, limiting the number of issues before judicial review (and limiting review on those issues according to the appropriate standard of deference).”).
Without a final agency decision on Nichole Medical’s claims, the district court lacks jurisdiction to review this action. See 42 U.S.C. § 405(h). Because §§ 1331 and 1332 jurisdiction is barred and the prerequisites of § 405(g) have not been satisfied, the district court properly determined that it was without subject matter jurisdiction to entertain Nichole Medical’s state law claims.
B. Official Immunity for Medicare Contractors
In the alternative, the district court also dismissed Nichole Medical’s action for failing to state a claim for which relief may be granted because it found TriCenturion and NHIC were entitled to official immunity. Our review of the district court’s grant of a motion to dismiss for failure to state a claim is plenary. Morse v. Lower Merion School Dist., 132 F.3d 902, 906 (3d Cir.1997). “In considering whether a complaint should have been dismissed for failure to state a claim upon which relief can be granted, [this Court] must consider only those facts alleged in the complaint and accept all of the allegations as true.” ALA, Inc. v. CCAIR, Inc., 29 F.3d 855, 859 (3d Cir.1994).
A Rule 12(b)(6) motion should be granted when it appears to a certainty that no relief can be granted under any set of facts which could be proved. Morse, 132 F.3d at 906. Though Nichole Medical’s complaint need not set forth detailed allegations, it must provide the grounds for its entitlement to relief which requires more than labels, conclusions and a formulaic recitation of the elements of a cause of action. See Bell Atlantic Corp. v. Twombly, 550 U.S. 544, 555, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007).
On appeal, TriCenturion and NHIC assert that, “as Medicare contractors — acting on behalf of the Secretary and performing functions under their contract with CMS — and because the complaint alleges only state-law tort claims, [Appellees] are entitled to official immunity.” Appellees’ Brief, p. 17. Nichole Medical argues that “government contractors who engage in illegal conduct have no claim to immunity” and, therefore, official immuni*351ty should not be extended to Appellees.17 Appellant’s Brief, pp. 18-22.
Nichole Medical’s argument is unpersuasive. TriCenturion and NHIC, as Medicare contractors, are entitled to immunity for discretionary conduct that falls within the outer perimeter of their official duties. Westfall v. Erwin, 484 U.S. 292, 300, 108 S.Ct. 580, 98 L.Ed.2d 619 (1988); see also 42 C.F.R. § 421.5(b) (Medicare contractors “act on behalf of the CMS in carrying out certain administrative responsibilities that the law imposes”); Midland Psychiatric Associates, 145 F.3d at 1003-4 (Medicare contractors are government agents because they are “[u]nder contract with the Secretary of Health and Human Services, [and] do the work of the Government on the Secretary’s behalf.”).
Under the Act, Appellees had discretion to suspend payments to recoup monies they believed had been overpaid to suppliers. See 42 C.F.R. § 405.371. Appellees were discharging that discretionary duty when they withheld benefits to recoup the perceived overpayments to Nichole Medical. See id. Since Nichole Medical is seeking damages purportedly arising from the exercise of Appellees’ discretion to withhold benefits they are seeking damages for the exercise of discretion that is easily within the outer perimeter of Appellees’ official duties. See id.
Accordingly, the district court properly found that Appellees are entitled to immunity and dismissed Nichole Medical’s complaint. See Bodimetric, 903 F.2d at 488 (“Congress apparently did not differentiate between the respective abilities of public and private agencies to serve as fiscal intermediaries, 42 U.S.C. § 1395h(a), we see no reason to allow claimants to proceed against private agencies when they clearly cannot proceed against federal agencies.”).
IV. CONCLUSION
For the forgoing reasons, we conclude that the district court properly granted Appellees motions under Fed. R. Civ P. 12(b)(1) and (6) and we will therefore affirm its decision.
