Gaudineer & Comito, L.L.P., a qui tam relator, brought this action under the False Claims Act against Iowa, the Iowa Department of Human Services (DHS), Gary Gesaman, an employee of DHS and the director of a state program which receives Medicaid funding, and other individuals and organizations which implement the state program. After the Supreme Court issued its decision in Vermont Agency of Natural Res. v. United States ex rel. Stevens, 529 U.S. 765, 120 S.Ct. 1858, 146 L.Ed.2d 836 (2000), relator voluntarily dismissed all of its claims except that asserted against Gesaman in his official capacity. It also moved for leave to amend its complaint to assert a claim against Gesaman in his individual capacity. The district court1 dismissed the action and denied the motion for leave to amend. Relator appeals, and we affirm.
Iowa received federal funding through DHS for a Medicaid program called the Home and Community Based Services Waiver. The waiver program allowed an individual with a developmental disability requiring intermediate level care to receive Medicaid funding for home and community based services rather than obtaining them in an institution. DHS promulgated and published eligibility rules for each year the waiver program was in operation. The Iowa rules defined “mental retardation” and “intermediate care facility.” See IOWA ADMIN. CODE 441-83.60. The Iowa regulations were consistent with federal law, and the United States Department of Health and Human Services and Iowa entered into a three year funding agreement for the waiver program in 1992 and a five year agreement in 1995. The program was administered by Gary Gesaman.
Relator sued Iowa, DHS, Gary Gesaman in his official capacity, and other parties for violating the False Claims Act (FCA), 31 U.S.C. § 3729. The FCA allows a private party, like the relator in this case, to bring a qui tam action on behalf of the United States alleging submission of a fraudulent claim to the government. A relator may recover damages and attorneys fees if it is successful, but it is required to deliver a copy of its complaint to the United States which has the right to intervene if it wants to pursue the claim. The United States has declined to intervene in this case.
The allegations in the complaint were based on information acquired by Carlton G. Salmons, one of the attorneys in relator law firm, while he was representing Keokuk County, Iowa in a state civil proceeding in which a key issue was whether an individual was mentally retarded. The federal district court abstained from hear*935ing relator’s claims until the state case had been concluded.
In the original complaint in this case relator sued the state, DHS, and Gesaman in his official capacity, alleging that they had defrauded the United States and inappropriately spent Medicaid funds. Relator alleged that DHS and Gesaman had disregarded published rules and that “Iowa, DHS, and Gary Gesaman ha[d] operated the [waiver] program ... allowing eligibility to those who were not mentally retarded.” In respect to its claims against Gesa-man in his official capacity, it alleged that contrary to DHS regulations, “[he] decided that between March, 1992 and August 1993 persons would be eligible [for the waiver program] ... with IQs of 78 or less,” and after August 1993 with IQ’s of 75 or less. Relator claimed that Gesaman, acting on behalf of the state and DHS, allowed person “with IQs of between 70 and 78 [to participate] knowing there would be an exponential increase in the numbers of persons eligible.” Relator asserted that “Iowa, DHS or Gary Gesaman [did not] disclose or inform the United States Department of Health and Human Services” about this aspect of the program. Relator also claimed that the individual in the Keokuk County case should not have been eligible for the program but had received federal funding. Relator sought triple damages, a civil penalty of up to $10,000 for each violation, costs, and attorney fees.
The defendants filed motions to dismiss on the basis that relator’s action was not authorized by the FCA, that it was barred by the Eleventh Amendment, and that Salmons was not the original source of the information. The district court denied the motions, and discovery was initiated. Then the Supreme Court issued its decision in Stevens, 529 U.S. at 788, 120 S.Ct. 1858, holding that states and state agencies were not “persons” subject to liability under the FCA. There was thus no longer a basis to sue them under the FCA, and relator voluntarily dismissed its claims except for that against Gesaman in his official capacity. Relator also moved to amend to assert a claim against Gesaman in his individual capacity.
Relator continued to maintain that it could sue Gesaman in his official capacity even after Stevens and also submitted a proposed amended complaint in support of its motion to amend. The proposed pleading, alleging a claim against Gesaman in his individual capacity, was almost identical to the original allegations against the state, DHS, and Gesaman in his official capacity. Relator merely eliminated Iowa and DHS from the allegations that published rules had been disregarded and that the waiver program had allowed “eligibility to those who were not mentally retarded” and now alleged them only against Gesa-man. Relator again alleged that “Gesa-man decided that between March, 1992 and August 1993 persons would be eligible [for the waiver program] ... with IQs of 78 or less,” and after August 1993 with IQ’s of 75 or less and that Gesaman operated the program knowing there would be an increase in eligible persons. Relator now left out its earlier allegation that Ge-saman was acting “for the Defendants State and DHS.” The allegations in the proposed complaint were directed against Gesaman alone, but no new facts were alleged about his role and responsibilities as program administrator or how he may have been acting in his individual capacity.
The district court dismissed the original complaint after concluding that the remaining claim against Gesaman in his official capacity was really against the state and barred by Stevens. It also denied relator’s motion to amend, reasoning that the proposed amendment would be futile since Gesaman had been implementing a *936state policy on behalf of DHS and had performed no acts in his individual capacity-
Relator argues on appeal that the district court erred in denying it leave to amend because Gesaman is a person amenable to suit under the FCA and the Eleventh Amendment does not bar its claims for money damages against him in either his official or individual capacity. Gesa-man responds that he did not act outside his official capacity, that he is not a person under the FCA because the state is the real party in interest, and that the claims are in any event barred by the Eleventh Amendment.
Although relator contended in its brief that Gesaman was a person under the FCA when he was acting in his official capacity,2 it conceded at oral argument that this position was no longer viable under Stevens. Since a damage claim against a state official in his official capacity is a suit against the state, see Kentucky v. Graham, 473 U.S. 159, 105 S.Ct. 3099, 87 L.Ed.2d 114 (1985), a state employee sued for money damages for actions taken in an official capacity stands in the shoes of the sovereign and is not a person under the FCA. See Stevens, 529 U.S. at 788, 120 S.Ct. 1858. The district court did not err in dismissing the damage claim against Gesaman in his official capacity.
Permission to file a first amended complaint “shall be freely given when justice so requires,” Fed.R.Civ.P. 15(a), but denial of leave to amend may be justified by “undue delay, bad faith on the part of the moving party, futility of the amendment or unfair prejudice to the opposing party.” Sanders v. Clemco Indus., 823 F.2d 214, 216 (8th Cir.1987). The denial of leave to amend based on futility means that the court found that the amended complaint failed to state a claim, and our review is therefore de novo. See J.R. Stripling v. Jordan Prod. Co., LLC, 234 F.3d 863, 873 (5th Cir.2000); Frey v. City of Herculaneum, 44 F.3d 667, 671 (8th Cir.1995).
The FCA, 31 U.S.C. § 3729, subjects to liability “[a]ny person” who “knowingly presents, or causes to be presented, to an officer or employee of the United States Government ... a false or fraudulent claim for payment or approval.” Although “person” has been defined by Congress to include “individuals,” 1 U.S.C. § 1, the term does not include states or state agencies. See Stevens, 529 U.S. at 788-89, 120 S.Ct. 1858, overruling in part, United States ex rel. Zissler v. Regents of the Univ. of Minn., 154 F.3d 870, 874-75 (8th Cir.1998) (holding that states are persons under the FCA).
Relator argues that Gesaman is a person when sued in his individual capacity for money damages under the FCA and claims that Gesaman acted in his individual capacity in extending the eligibility requirements and that the state is not the real party in interest. It also argues that whether an official is a person under the FCA should be construed the same as “person” under 42 U.S.C. § 1983. Gesaman responds that the state is the real party in interest because he did not act in his individual capacity, the Iowa indemnification statute would require that any judgement be paid with state funds, the complex DHS administrative process impacts critical aspects of state sovereignty, *937and a judgment against Mm would require Iowa to alter its waiver program.
In determining whether a state official may be liable for money damages in his individual capacity, courts should not rely wholly on “the elementary mechanics of captions and pleading.” Idaho v. Coeur d’Alene Tribe of Idaho, 521 U.S. 261, 270, 117 S.Ct. 2028, 138 L.Ed.2d 438 (1997). We should look at whether the alleged conduct of the defendant was “outside of [his] official duties.” Bly-Magee v. California, 236 F.3d 1014, 1016 (9th Cir.2001). Relator’s allegations arise out of a multi year federal waiver program which Iowa was to administer, and Iowa delegated responsibility to determine eligibility to DHS and Gesaman. Iowa was the party which had the contractual relationship with the United States which would make it liable to the federal government for monies wrongly paid. After Stevens an FCA relator can no longer pursue money damages from the state, which Gesaman claims is the real party in interest.
When relator’s original claims were blocked by the Stevens decision, relator attempted to add a claim against Gesaman in his individual capacity for the same acts it had previously alleged he was performing in his official capacity. Relator added no new or different factual allegations in its amended complaint, but simply reworded its complaint to remove Iowa and DHS as defendants and to eliminate statements that Gesaman was acting “for the Defendant State and DHS.” Relator has not alleged what Gesaman’s specific duties or powers were as administrator of the program or how he acted outside those duties by issuing eligibility standards which allegedly conflicted with state regulations.
Without any allegations about the extent and nature of Gesaman’s duties, the mere assertion that he issued standards that conflicted with state law does not allege actions outside his official duties as administrator of the waiver program. Relator also has not provided any specifics of the agreements between the United States and Iowa or how Gesaman’s actions may have been in violation of those agreements and federal law. Under these circumstances, the district court did not err in denying the motion for leave to amend to add a new claim against Gesaman in his individual capacity.3
Since the district court did not err in dismissing the complaint or in denying the motion to amend, we affirm the judgment.
. The Honorable Charles R. Wolle, United States District Judge for the Southern District of Iowa.
. Relator had argued in its brief that United States ex rel. Rodgers v. Arkansas, 154 F.3d 865 (8th Cir.1999), would permit the suit against Gesaman in his official capacity. Rodgers did not address the statutory question of whether a damages claim can be. made under the FCA against state officials in their official capacity, however.
. In light of this conclusion, we need not consider whether a state official sued in his individual capacity is a person under the FCA or whether the claims against Gesaman are barred by the Eleventh Amendment. We also need not reach the issue of whether the term "person” under the FCA should be construed as under § 1983, a position advanced by relator without citation to any authority.
