Home Ventilator Billing Fraud: When a Respiratory Assist Device Would Have Met the Need

Home ventilator Medicare fraud includes knowingly billing for a ventilator when a patient needs a less expensive respiratory assist device, or continuing monthly claims after the patient stops using the equipment. A respiratory therapist may see a machine sitting unused. A billing employee may see the rental claim go through again. The clinical record, the device settings and the company’s instructions can connect those separate views of the same patient.

The money follows the category on the claim. The treatment follows the patient’s condition. When those part company, taxpayers can keep paying for equipment that delivers less than the bill promises, or no treatment at all.

Why a Home Ventilator Pays Differently

Medicare’s payment categories give a supplier more than a higher price for a home ventilator. They give it a continuing rental stream. Ventilators belong to the frequent and substantial servicing category, which has no rental cap or transfer of ownership to the patient. By comparison, a CPAP device reaches patient ownership after 13 paid rental months.

The difference shows up in the Medicare equipment payment data. In 2024, the average payment per rental month for a noninvasive home ventilator, code E0466, was about $953. Bi-level respiratory assist devices averaged about $91 without a backup rate, code E0470, and $227 with one, code E0471. The category determines both the size of the payment and how the rental business works.

The Department of Health and Human Services inspector general’s 2016 ventilator review explained why the technology made this distinction consequential. A single device could operate in CPAP, respiratory assist or traditional ventilator mode. Medicare covered ventilators and respiratory assist devices for overlapping diagnoses, with the choice depending on the severity of the patient’s condition.

That review found that Medicare paid 85 times as many claims for ventilator code E0464 in 2015 as in 2009. Three national suppliers accounted for 54 percent of the growth in beneficiaries with those claims from 2012 to 2015. Use shifted toward respiratory conditions and away from neuromuscular conditions.

Home Ventilator Billed When Patient Uses Respiratory Assist Settings

A home ventilator billed when the patient uses respiratory assist settings raises a specific comparison: what treatment the clinician ordered, what the machine actually delivered and what category the supplier billed. The name on the machine leaves the treatment question unanswered.

Apria Healthcare’s December 2020 settlement shows the decision inside a sales operation. The company agreed to pay $40.5 million to resolve claims involving ventilator rentals and improper copay waivers. Three former employees brought the qui tam case. The allegations included TRICARE claims.

Apria admitted that in 2015 it encouraged salespeople to urge physicians to order Astral ventilators in PAC mode. Salespeople frequently did not tell physicians that the same mode of therapy was available through a less expensive VPAP respiratory assist device. On some occasions, patients received the more expensive ventilator even though the cheaper device may have met their medical needs.

Apria also admitted that branch managers authorized copay waivers to persuade patients to rent ventilators from Apria instead of competing suppliers. It granted full waivers to hundreds of patients without assessing whether they could afford part of the payment. The sales pitch reached both sides of the order: the physician choosing the equipment and the patient choosing the supplier.

What Is Covered Under Durable Medical Equipment?

For home respiratory equipment, Medicare coverage turns on the patient’s medical need and the treatment selected. The diagnosis needs clinical detail behind it. The inspector general’s ventilator review described how the same respiratory diagnosis could lead to different device choices depending on severity. A prescription saying ventilator does not explain that difference by itself.

The 2021 Sleep Management audit shows why the supporting records matter. An independent medical reviewer examined monthly rental claims paid in 2016 and 2017. The inspector general found that 98 of 100 sampled claim lines failed Medicare requirements and estimated at least $29,131,187 in overpayments. It attributed the problem to insufficient documentation of medical necessity and failure to discontinue service for lack of patient use.

The treatment rules also have dates. A Centers for Medicare & Medicaid Services respiratory-device policy revision effective June 9, 2025 aligned the policy with new national coverage for home ventilation treating chronic respiratory failure caused by COPD. The clinical notes, prescription and treatment settings need to explain the device selected for that patient at that time.

When the Patient Stops Using the Ventilator

Continuing monthly ventilator billing depends on continued use and medical necessity. A supplier’s respiratory staff may know the patient has stopped using the machine while its billing operation keeps sending claims.

Lincare agreed to a $25.5 million civil settlement in February 2024 over ventilator billing and coinsurance waivers. It admitted that staff frequently failed to make the home visits, called vent checks, required by its own policy every 60 days. Some centers lacked enough staff to monitor patients, and visits sometimes went unperformed for months.

The company also admitted that it could remotely monitor usage for certain newer ventilators but did not use those systems to confirm patient use. It continued monthly claims in many instances without verified use or documentation. In some instances, Lincare knew patients were not using the devices and kept seeking payment anyway.

The visit note, the usage data and the monthly claim describe different parts of that decision. A respiratory therapist’s observation can show what was happening in the home. The company’s response shows whether that information ever changed the bill.

Respiratory Billing Cases Expose Different Decisions

The cases against AdaptHealth, SuperCare and Oxygen Plus put different parts of the rental process in view: the code selected, the need for the ventilator and the decision to keep billing. Each began with an employee who could see inside the business.

AdaptHealth and the Device on the Claim

AdaptHealth, formerly QMES, agreed to a $5.3 million settlement announced in April 2023. The matter involved Medicare and the Federal Employees Health Benefits Program. A former employee’s complaint alleged that the company billed Medicare for ventilators while supplying BiPAP devices:

The complaint also alleged that executives directed continued billing under incorrect codes for existing patients and instructed staff not to notify payers. That allegation connects the original code choice to a later management decision. The billing problem allegedly continued after people inside the company had identified it.

SuperCare and the Need for the Service

SuperCare Health agreed to a $3,315,308 settlement announced in August 2021 with the United States, California and Nevada. The allegations concerned billing for ventilator services that were not medically necessary or reasonable.

A respiratory therapist who worked for SuperCare brought the case. That role puts the treatment itself in view: the reason for the device and what service the patient actually receives.

Oxygen Plus and the Unused Machines

Oxygen Plus agreed to a $200,000 settlement announced in October 2023 over allegations that it billed Medicare and Medicaid for respiratory devices patients did not need or use. Two former employees brought the case.

Their complaint alleged that the company used a six-question form called “Questionable Vent Patients” to find existing customers for ventilator rentals, then pressured healthcare providers to write orders. It alleged that some patients likely qualified for a less costly BiPAP device and that staff objections did not stop the solicitations.

The respiratory therapist’s allegation brought the monthly claim into the patient’s home:

The alleged sales process generated the order. The therapist then saw what happened after delivery. Both parts belong beside the recurring claims when examining why the rentals continued.

What Respiratory Staff and Billing Employees Can Show

The strongest connection runs from the reason for the prescription to the equipment delivered, the treatment settings, the patient’s use and the monthly claim. Respiratory staff can explain the clinical notes and usage records. Billing staff can explain the code and the instructions that kept a rental active. A manager’s response to a reported problem can connect those records to the company’s decision.

The Apria admissions show salespeople steering the order toward more expensive equipment. The Lincare admissions show monitoring failures and claims continuing after known nonuse. The QMES complaint alleges instructions to keep using incorrect codes. Admitted or alleged, those are decisions inside a health care business, and they give a whistleblower case its substance.

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