Before Smith, Higginson, and Willett, Circuit Judges. Jerry E. Smith, Circuit Judge: George Martinez appeals the dismissal of his 42 U.S.C. § 1983 claims against Nueces County, Texas, and the denial of leave to amend his § 1983 claims against Wellpath, L.L.C.[1] Finding no error, we affirm. I. Martinez was incarcerated in the Nueces County Jail in September 2019.[2] He notified”[d]efendants”[3] that he had severe problems with his foot and had been scheduled for surgery. He alleges that he continued to submit complaints about “the increasingly horrific condition of his foot” and about his medications and antibiotics, but “[d]efendants continually ignored [his complaints] over a significant period of time.” “As a result,” Martinez’s toe “exploded,” and all his toes on that foot were “unnecessarily amputated/removed.” Martinez sued Nueces County and Wellpath for “County/Municipal [L]iability” under § 1983. Specifically, he alleged that the county was liable because it “sanctioned the custom, practice, and/or policy or procedure of failing to protect and/or ignoring the serious medical needs of those entrusted to [its] care.” The original claim was not specific about how Well-path was supposedly liable. The county and Wellpath moved to dismiss. The district court granted both motions but permitted Martinez to file a “Motion for Leave to Amend his Complaint.” Martinez did so and attached a proposed amended complaint, but the judge denied the motion, finding that any amendment would be futile. Martinez timely appeals the dismissal of his claim against Nueces County and the denial of leave to amend as to Wellpath.[4] II. We begin with the dismissal of the claims against Nueces County. We review a dismissal de novo. Lampton v. Diaz, 639 F.3d 223, 225 (5th Cir. 2011). We ask whether, construing all inferences in favor of the plaintiff, there are sufficient factual allegations “to raise a right to relief above the speculative level.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007). There is no “heightened pleading requirement” for actions against municipalities. Anderson v. Pasadena Indep. Sch. Dist., 184 F.3d 439, 443 (5th Cir. 1999) (citing Leatherman v. Tarrant Cnty. Narcotics Intel. & Coordination Unit, 507 U.S. 163, 166–67 (1993)). As with all motions to dismiss, the court must determine whether the plaintiff has pleaded “factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged” such that he has “‘state[d] a claim to relief that is plausible on its face.’” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (quoting Twombly, 550 U.S. at 570). Martinez alleged that Nueces County violated § 1983 by “acting with deliberate indifference to a substantial and known risk of harm to [p]laintiff,” “ignoring [p]laintiff’s serious medical needs,” and “failing to impose proper and sufficient policies and/or procedures as to the screening, reassessment and medical treatment of inmates/detainees/arrestees in regard to their medical needs and/or training concerning same.” Nueces County cannot be held liable under § 1983 unless “execution of a government’s policy or custom, whether made by its lawmakers or by those whose edicts or acts may fairly be said to represent official policy, inflicts the injury.” Monell v. Dep’t of Soc. Servs. of City of N.Y., 436 U.S. 658, 694 (1978). This is an important distinction: A plaintiff may not recover against a municipality via theories of respondeat superior—the municipality itself must be responsible for the constitutional violation. To succeed, the plaintiff must show “(1) an official policy (or custom), of which (2) a policy-maker can be charged with actual or constructive knowledge, and (3) a constitutional violation whose ‘moving force’ is that policy or custom.” Pineda v. City of Houston, 291 F.3d 325, 328 (5th Cir. 2002) (quoting Piotrowski v. City of Houston, 237 F.3d 567, 578 (5th Cir. 2001)). Such claims are referred to as Monell claims. A Monell claim does not require the plaintiff to identify a written pol-icy. In some situations, a plaintiff can succeed by pointing to similar incidents that are “sufficiently numerous” and have “occurred for so long or so frequently that the course of conduct warrants the attribution to the governing body of knowledge that the objectionable conduct is the expected, accepted practice of city employees.” Peterson v. City of Fort Worth, 588 F.3d 838, 850–51 (5th Cir. 2009) (quotations omitted). Martinez has attempted to plead Monell in this way, providing a list of examples that he claims support his allegations that Nueces County had a policy of “ignoring the serious medical needs of those entrusted to [its] care.”[5] In Bond v. Nueces County, No. 20-40050, 2022 WL 4595000, at *5 (5th Cir. Sept. 30, 2022) (unpublished), we accepted this way of establishing a policy. But we cannot accept Martinez’s version: Martinez fails because the pattern of examples must have “similarity” and “specificity.” Davidson v. City of Stafford, 848 F.3d 384, 396 (5th Cir. 2017). “Prior indications cannot simply be for any and all ‘bad’ or unwise acts, but rather must point to the specific violation in question.” McCully ex rel. Estate of Davis v. City of N. Richland Hills, 406 F.3d 375, 383 (5th Cir. 2005) (internal quotations removed). Because Martinez’s description of what happened to him is so vague, we cannot accept that the proffered examples are sufficiently similar to his own incident that the municipality can be found liable. Consider the above-referenced Bond, where the mother of the deceased Tami Bond sued Nueces County for policies that allegedly caused Tami’s death. This court held there was “enough . . . [to] determine whether the past incidents were like Tami’s death” because the complaint described what happened to Tami in sufficient detail. Bond, 2022 WL 4595000, at *6. For example, we outlined how officers “observed that Tami had seemingly become extremely intoxicated, stumbling and slurring her speech, but the officers did not have Tami medically reassessed or otherwise address the signs of a possible narcotics over-dose.” Id. at *2. We noted that Tami was “unwilling or unable to follow verbal commands,” but officers put her into a “holding cell” instead of calling for assistance. Id. at *1. The specificity in that pleading allowed the court to say that the occurrence was similar enough to the previous incidents that the county’s acquiescence in the pattern of previous incidents was the moving force behind Tami’s injury.[6] Not so here, where the entirety of Martinez’s specific allegations is that “despite [Martinez's] numerous complaints concerning his medications, antibiotics, and . . . condition of his foot, Defendants continually ignored such over a significant period of time.” The bar to survive a motion to dismiss is low, but not that low. On the face of these allegations, we cannot say that it is plausible that the county’s policy, as distinguished from the isolated acts of the employees who interacted with Martinez, was responsible for what happened to Martinez.[7] Because Martinez has not properly alleged a custom or policy that was the moving force of his injuries, the district court was correct to dismiss his claims against Nueces County. III. We turn now to Wellpath. Martinez’s initial complaint mentioned Wellpath only in passing and couched the rest of the complaint as against Nueces County. Accordingly, the district court dismissed the claims against Wellpath as failing to state a claim upon which relief could be granted, but the court gave Martinez permission to file a motion to amend his complaint. He did so and included a proposed amended complaint along with several exhibits related to his allegations against Wellpath. The district court denied his request, finding that amendment would be futile. Martinez appeals only this denial of leave to amend. We review denials of leave to amend for abuse of discretion bounded by the Federal Rules of Civil Procedure, Lowrey v. Tex. A & M Univ. Sys., 117 F.3d 242, 245 (5th Cir. 1997); but when a court denies leave to amend for futility of amendment alone, our analysis mimics that of a motion to dismiss. Ariyan, Inc. v. Sewage & Water Bd. of New Orleans, 29 F.4th 226, 229 (5th Cir. 2022). “If the complaint, as amended, would be subject to dismissal, then amendment is futile and the district court was within its discretion to deny leave to amend.” Id. As with reviewing an order to dismiss, our review of denial of leave to amend is de novo. Thomas v. Chevron U.S.A., Inc., 832 F.3d 586, 590 (5th Cir. 2016). We therefore ask whether, in his proposed amended complaint, Martinez has pleaded “factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Iqbal, 556 U.S. at 678. We read Martinez’s proposed amended complaint as alleging that Wellpath, as a state actor, had a pattern or policy of deliberate indifference as to adequate medical care, and that policy was the moving force behind a deprivation of Martinez’s constitutional rights that led to his injury. Assuming, without deciding, that a nationwide corporation such as Wellpath can be sued as a municipality,[8] we proceed to the merits. As with his claim against Nueces County, Martinez must show the existence of a policy or custom that was the moving force behind the violation of his constitutional rights. Spiller v. City of Tex. City, Police Dep’t, 130 F.3d 162, 167 (5th Cir. 1997). Martinez has alleged a custom or policy of deliberate indifference. Again, he can show this via a pattern that has “occurred for so long or so frequently that the course of conduct warrants the attribution to the governing body of knowledge that the objectionable conduct is the expected, accepted practice of [Wellpath's] employees.” Davidson, 848 F.3d at 396 (quoting Peterson, 588 F.3d at 850). And again, there is not enough detail in Martinez’s complaint to clear this bar. Martinez’s proposed amended complaint included exhibits describing lawsuits, allegations, and investigations against Wellpath for injuries and deaths of inmates from medical negligence, along with allegations that Wellpath continuously prioritizes profit over quality medical care. The complaint concludes that “Wellpath, in an effort to make money, has a history of incompetence, failure to train, failure to provide even the basic care and has systemically denied, ignored and/or refused to provide medical care.” That is not enough. Wellpath is a nationwide company that operates in jails and other institutions across the country. Plaintiff’s own exhibits state that the company operates in more than 500 facilities in 34 states and is responsible for around 300,000 people in custody every day.[9] The complaint does not allege a single instance of medical negligence (aside from his own) that occurred in Nueces County and that was caused by Wellpath.[10] In fact, it is unclear from the face of the complaint what exact role Wellpath even played at Nueces County. True, a plaintiff is not required to identify the precise policymaker to make out a Monell claim. Balle, 952 F.3d at 552. But he is required to “state a claim to relief that is plausible on its face,”[11] and from the face of Martinez’s pleadings, there is no reason to conclude that Wellpath, at an organization-wide level, had a policy of deliberate indifference that was the moving force of Martinez’s alleged constitutional violation at the Nueces County Jail. This is doubly so because of Martinez’s failure to allege, with sufficient detail, what happened to him at the jail. Martinez’s sparse complaint and conclusory allegations would not survive a motion to dismiss. Denial of leave to amend was therefore proper. The dismissal of the claims against Nueces County and denial of leave to amend the claims against Wellpath are thus AFFIRMED.
