Alert — how to use this page
This case involves invasive medical procedures on real patients — many of them Navajo and other Native relatives living with diabetes and peripheral artery disease. The federal lawsuit here is an allegation, not a verdict; the company denies wrongdoing and the litigation was still moving through the courts in the most recent records we found. This page names no private individuals, marks each item’s status, and exists to practice one skill: seeing where a system’s oversight seams sit — so the community can judge what candidates propose to close them. If you or a relative had procedures at one of these clinics, see the bottom of this page.
What happened, in one paragraph
A Phoenix-based chain of outpatient vascular clinics grew rapidly treating peripheral artery disease (PAD) — a complication of diabetes that can lead to amputation — including through a clinic entity the U.S. Department of Justice lists as “Modern Vascular - Navajo LLC.” Investigative reporting by Searchlight New Mexico and The Arizona Republic in 2022 described patients, doctors, and former employees alleging profit-driven, unnecessary procedures. In December 2022 the DOJ filed a False Claims Act complaint alleging the chain’s founder offered physician-investors equity stakes to induce patient referrals and pressured clinic doctors to increase invasive procedures. The company publicly denied the allegations. Medicare suspended payments in early 2023; the chain’s management company filed for bankruptcy months later; in March 2024 a federal judge declined to dismiss the government’s case. The reporting also traced how the chain’s lead surgeon — who had a documented criminal past — including a felony drug conviction, later commuted — and prior state medical board discipline, and who had earlier worked in Tuba City — continued rising through the system. Every step of that record is public, and this page shows where to find it.
The documented timeline
Each item marked by status
Reported = investigative journalism · Alleged = claims in lawsuits · Action = official act on the record · Response = the company’s position
- 2017 — founding. The chain is founded in Phoenix, operating “office-based labs” (OBLs) — outpatient clinics performing vascular procedures outside hospitals. It grows to more than a dozen clinics in several states. (Public record / company statements)
- June 2022 — reported. Searchlight New Mexico publishes a six-month investigation: patients, doctors, and former employees allege unnecessary procedures and profits-first pressure; malpractice suits are filed.
- October 2022 — reported. The Arizona Republic publishes its investigation: claims that patients were harmed or died after procedures; the chain’s lead surgeon’s documented history — a criminal record including a felony drug conviction whose sentence was commuted in 2002 while co-defendants served theirs in full, later work in Tuba City, prior Arizona Medical Board discipline, and a 2022 board censure — drawn from court, clemency, and board records.
- December 13, 2022 — action & alleged. The DOJ files a False Claims Act complaint against the founder, 15 clinic entities (including Modern Vascular - Navajo LLC), and 5 affiliated companies — alleging that from January 2018 to June 2022 physician-investors were offered equity to induce Medicare and TRICARE referrals, and that clinic doctors were pressured with procedure tracking and aggressive weekly goals. These are allegations.
- December 2022 — response. The company publicly states the complaint lacks merit, says its structure complies with the law, and notes the government’s complaint does not allege its specialists performed medically unnecessary procedures.
- February 2023 — action. Medicare suspends payments to the clinics pending the lawsuit — the program had covered roughly half the chain’s patients.
- May 2023 — action. The chain’s parent management company files for Chapter 11 bankruptcy; reporting notes the clinic count falling from seventeen to five.
- March 2024 — action. A federal judge in Arizona denies the defendants’ motions to dismiss; the government’s case proceeds. As of the most recent records this page’s sources found, the litigation had not reached a final judgment — check the sources below for the current status.
The structural lesson: the border-clinic oversight seam
Who was supposed to be watching?
The system question this case teaches
Nation members with diabetes are often referred off-Nation for specialty care — including through Purchased/Referred Care. Outpatient clinics in border towns can treat mostly Nation patients, bill Medicare and Medicaid for them, even carry “Navajo” in the entity name — while sitting outside every oversight ring the Nation controls:
- Nation licensure (NDOH’s authority under CO-50-14, including the Quality Control and Performance Improvement Center’s credentialing role) reaches providers on the Navajo Nation — not an LLC in Phoenix or Farmington.
- Hospital credentialing & privileging (the checks a hospital runs before letting a physician operate — see the Academy lesson) doesn’t apply: office-based labs aren’t hospitals.
- State medical boards discipline individual physicians — and their orders are public — but board discipline in one chapter of a career doesn’t automatically stop the next chapter.
- Medicare pays claims first and investigates later; here, whistleblower suits and journalism came before the payment suspension.
The seam: each watcher covered its own square, and the patients lived in the space between the squares. That’s not unique to this company — it’s the same shape as the sober-living scheme: services aimed at Native patients, funded by public insurance, sitting where no single regulator owns the whole picture.
Reading it with the five lenses
Practice the lenses on this case
Evaluation tools — the same lenses used across this site
- Root cause: Is the problem bad actors, or a payment system that rewards procedure volume on a population with high diabetes rates — or both?
- Jurisdiction: Which pieces could the Nation actually control (referrals, PRC contracting standards, patient navigation) and which belong to states, CMS, and federal courts?
- Evidence: Notice which statements are journalism, which are sworn allegations, which are court actions, and which are the company’s denials. The timeline above marks each.
- Transparency & accountability: Every fact on this page came from a public record — board lookups, DOJ filings, court dockets, investigative reporting. Could a voter have found it before the harm was alleged?
- K’é: Patients followed referrals in good faith to protect their limbs and their lives. What does a system owe relatives at their most vulnerable?
Questions to ask any candidate
Carry these to a forum
Community participation
- When Nation patients are referred to off-Nation clinics, who checks those clinics — and should PRC contracts require credentialing standards the Nation sets?
- Should the Nation publish a plain-language guide to looking up any physician’s license and discipline history before an appointment?
- The NDOH has regulatory authority on the Nation under CO-50-14. What would you do with it — and what would you propose for the border-town seam it doesn’t reach?
- Diabetes drives the amputation risk that these clinics treated. What’s your prevention plan, so fewer relatives ever need a vascular clinic?
If you or a relative were affected
Practical steps — no lawyer needed to start
• Look up any physician’s public record: Arizona Medical Board license search at azmd.gov — discipline orders are public documents anyone may read. New Mexico: nmmb.state.nm.us.
• Questions about a past procedure: ask your IHS or 638 provider for your records and a second opinion — you have a right to both.
• Report suspected Medicare fraud: 1-800-MEDICARE or the HHS Office of Inspector General at oig.hhs.gov.

Where this record comes from
The timeline and statements above are drawn from these primary and investigative sources — the naming of individuals is theirs, and the current case status is theirs to update:
• U.S. Department of Justice press release (Dec. 13, 2022) — the complaint, the alleged scheme dates, and the full defendant list, including Modern Vascular - Navajo LLC.
• The Arizona Republic investigation (Oct. 5, 2022) — patient accounts, the lead surgeon’s documented history including his time in Tuba City, and the 2022 board censure.
• The Republic’s video report on the investigation (YouTube) — their own summary of what they found, in their words.
• Searchlight New Mexico — the original June 2022 investigation and DOJ complaint coverage, including the roughly $50 million in claims alleged.
• The Arizona Republic (May 2023) — the Medicare payment suspension and the Chapter 11 filing.
• U.S. ex rel. Radhakrishnan v. Gampel, D. Ariz. (Mar. 2024) — the court’s denial of the motions to dismiss; litigation status.
Allegations, not verdicts
The DOJ complaint states claims the government must still prove; the company denies them; the malpractice suits are civil claims. Board orders and the Medicare suspension are official actions on the record. This page will be corrected as the record develops — tell us if you spot an update.

How this site handles a case study
The same rules on every one. The Covenant
- We name no private individual. Public officials are named in their public capacity, and their own statements are printed alongside.
- An allegation is not a finding. An indictment is an allegation. A dismissal on jurisdiction decides nothing about the facts. Everyone is presumed innocent until proven guilty.
- Where a party declined to comment, we say so — and we do not treat silence as an admission.
- Claims are labeled as claims, findings as findings. Every page carries a verification level.
- No case study is linked from any candidate’s profile, in either direction. A case is not a mark against a person.
- These exist to practice evaluation — not to decide a dispute. The five lenses
What this case study does not say
It names no physician and reaches no verdict beyond what courts have reached. Some matters were resolved by settlement or bankruptcy; some allegations were never adjudicated at all.
The company did not respond to the reporting on which this page relies, so far as the published record shows. We do not treat that silence as an admission.
The reason this case is here is not what any individual did. It is that a clinic in a border town, treating Diné patients and billing federal programs, sits outside every oversight ring the Navajo Nation controls. Who watches the money? → · The Seams →
