DME Supplier Ownership: Who Owned the Business When the Billing Changed?

In private equity DME supplier fraud, the question is which company billed, who owned it at the time and who directed its billing. An employee asking who owns the supplier needs the legal entity behind the business and ownership documents for the period in question. You may know who told the billing team to keep submitting claims, even when the investor announcement says little about how the business actually ran.

The Supplier Name and the Company Behind It

A supplier location, a billing identifier and a corporate parent describe different parts of the business. Medicare enrollment records connect locations and NPIs, the identifiers used in billing, to legal entities. A parent company can own several of those entities. Counting storefronts or billing numbers therefore gives a different answer from counting owners.

This matters in durable medical equipment because acquisitions can bring regional suppliers into a larger group while their legal names survive. Linde’s subsidiary list, for example, includes Lincare entities alongside American HomePatient and Health Care Solutions at Home.

For an insider, the connections are concrete. Which company employed you? Which entity submitted the claim? Which office issued the instruction? We connect those answers to the parent and investment records for the period when the billing happened. The employee who saw an instruction and the filing that identifies an owner each supply a different part of that account.

Who Owns Durable Medical Equipment?

Ownership of the equipment depends on its payment category. With capped-rental equipment, title can pass to the patient after the rental period. An oxygen supplier keeps title and continues furnishing the equipment after the equipment-payment cap.

Who Owned AeroCare When AdaptHealth Announced the Purchase?

AeroCare’s owners included Peloton Equity, SkyKnight Capital, SV Health Investors, management and employees when AdaptHealth announced its purchase agreement on December 1, 2020. The announcement filed with the SEC identifies them as private investors. It describes AeroCare as a respiratory and home medical equipment business supplying CPAP and BiPAP machines, oxygen concentrators, home ventilators and other equipment directly to patients.

The proposed transaction valued AeroCare at approximately $2.0 billion, with $1.1 billion in cash and 31 million AdaptHealth shares. The announcement expected the transaction to close in the first quarter of 2021, subject to closing conditions and regulatory approvals.

AdaptHealth also said it intended to finance the cash portion and associated costs through additional debt. The announcement anticipated a larger geographic reach and stronger relationships with referral partners, manufacturers and health care plans.

AdaptHealth said a Peloton Equity shareholder designee would join its board at closing.

Who Owns Lincare?

The Justice Department’s August 2023 account identifies Lincare Holdings as a wholly owned subsidiary of Linde plc. Its parent at the time was an industrial gas company, not a private equity firm.

Lincare’s Billing Instructions Show the Other Half

In a qui tam case brought by two former employees and joined by the government, Lincare agreed to a $29 million settlement in August 2023 and admitted improperly billing Medicare, Medicare Advantage plans and beneficiaries for oxygen equipment rentals after receiving three years of payments. Lincare also admitted that regional billing officials and corporate headquarters instructed employees who raised concerns that the billing would continue.

What Is the DME 36-Month Rule?

The 36-month ownership rule for durable medical equipment suppliers generally requires a new owner to obtain new Medicare enrollment and accreditation when a supplier undergoes a qualifying majority-ownership sale within 36 months of its initial enrollment or its last majority-ownership change. The Centers for Medicare & Medicaid Services describes that requirement in its DMEPOS accreditation guidance. Specified internal restructurings and other exceptions receive different treatment.

This rule concerns the sale of the supplier. Oxygen’s rental-payment cap concerns payments for the equipment.

For an ownership inquiry, the transaction date belongs beside the enrollment history and the dates of the claims. We examine those together with the legal entities involved. The question is who held the business and its billing privileges when the disputed practice occurred.

The agency also imposed a six-month nationwide pause on new Medicare enrollments for covered medical supply companies beginning February 27, 2026. Its moratorium notice said the pause also blocked re-enrollment after a majority-ownership change that required the supplier to enroll anew under the ownership rule. Buying an existing supplier could therefore bring the buyer back to the same closed enrollment door.

When the Ownership Change Meets the Claims

Ownership timing can reveal a sharp change in a supplier’s billing. The Centers for Medicare & Medicaid Services described a rise in catheter claims in early 2023 from 15 durable medical equipment supply companies that had recently changed ownership.

In a separate criminal case, the indictment described in the Justice Department’s Operation Gold Rush announcement alleged that an organization bought suppliers with Medicare billing privileges, paid people to appear as owners and created false corporate records hiding who controlled them. The acquired companies allegedly submitted false claims using stolen identities.

The Old Company Name Can Carry the Case

AdaptHealth LLC, formerly QMES, agreed to a $5.3 million settlement announced in April 2023 over allegations of billing for ventilators while supplying BiPAP devices. A former QMES employee brought the case. The settlement announcement uses the later company name, while the employee’s complaint uses QMES.

The employee’s complaint alleged that managers directed continued Medicare billing under incorrect codes and instructed staff against notifying payers.

Private Equity Ownership and DME Billing Decisions

An insider who knows who approved a supplier’s billing or sales arrangement can help us connect that decision to its owners.

A whistleblower complaint against Respironics alleged that the manufacturer supplied AeroCare with valuable prescribing data free of charge while selling it respiratory products. The complaint described the data as a way for suppliers to identify physicians to target for sales, and alleged that Respironics provided it to encourage recommendations of its products.

The passage below is the whistleblower’s allegation in the complaint against the manufacturer. This page does not report an outcome for AeroCare.

What Evidence Is Needed for Reporting Fraud?

For a supplier-ownership question, useful evidence connects the claim to the equipment, the instruction and the people controlling the business at that time. An employee may know which office changed the billing practice, which managers received objections or how a product recommendation became a paid claim. We work through that account with the employee and connect it to the ownership dates.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

You Know Who Gave the Instruction

If you worked inside a supplier and know who directed the billing, speak with our whistleblower experts about the company, the instruction and when it happened. We build your strongest case around those decisions, connect them to the ownership history and bring in durable medical equipment fraud whistleblower lawyers who know oxygen and respiratory billing cases. We stay beside you as your partners through the case.
