Home Sleep Test Billing Fraud: Attended Studies and Approved Sites on Paper

An operator can commit fraud by billing a home sleep test as an attended sleep laboratory study that it never provided. If you assign devices, schedule technicians or submit claims, you may know why the recording and the bill describe different work. This page follows tests that were performed but misrepresented by attendance, service type or testing site.

Can a Home Sleep Test Be Billed to a Public Health Care Program?

Yes. Medicare’s national sleep-testing coverage decision covers specified home tests for people with signs and symptoms of obstructive sleep apnea. The covered service depends on what the device records, how the test is attended and where it occurs. Those details give an insider something concrete to compare with the claim.

The Centers for Medicare & Medicaid Services describes Type I polysomnography as an attended study in a sleep laboratory. It records brain activity, eye movements, muscle activity, heart activity, airflow, respiratory effort and oxygen saturation. A technologist supervises the recording during sleep and can intervene when needed. That attendance is part of the service Medicare covers.

Portable monitors record different combinations of signals. Medicare covers specified portable tests performed unattended inside or outside a laboratory, or attended in a laboratory. The device’s recorded signals and the technician’s attendance describe separate parts of the service.

Does a Physician Have to Be at the Bedside Throughout a Study?

No, not under general supervision. The physician directs and controls the service without having to be present during its performance. Technician attendance during Type I recording is a separate requirement from physician supervision. The physician’s interpretation afterward supplies another part of the work. For someone reviewing an attended-study claim, the technician’s recording and intervention record answers a different question from the physician’s signed report.

Which Codes Describe the Test That Was Performed?

The attended polysomnography codes at issue in the Coastal criminal case were 95810 and 95811, with the latter including initiation of CPAP therapy or bilevel ventilation. The charging document describes both as requiring a technologist’s attendance. Device assignment, recorded signals and attendance records supply the comparison with that representation.

The home-test code families describe different services. CMS’s short descriptors identify 95800, 95801 and 95806 as unattended studies, with differences in the work described. G0398, G0399 and G0400 identify Type II, Type III and Type IV home testing respectively. Which code fits a claim depends on the actual service and the payer’s rules for it.

Modifier 26 identifies professional interpretation, TC identifies the technical component, and a global diagnostic service includes both. A report sent from another location belongs in the interpretation trail. The raw recording and attendance records establish what happened while the patient was being tested.

Why the Approved Sleep Testing Site Must Match the Claim

For an independent diagnostic testing facility, enrollment attaches to the practice location. The Centers for Medicare & Medicaid Services’ enrollment instructions require separate enrollment for each practice location, with an exception for locations used only for warehousing or repair. The relevant comparison brings together the legal entity, its National Provider Identifier, the approved physical location, the approval dates, the services approved there and the place the patient actually underwent testing.

A corporate address or shipping label cannot settle that comparison. The device assignment and recording answer where and how the test was performed. The place-of-service rule distinguishes testing wholly administered at the patient’s location from arrangements in which the testing facility performs part of the service. We examine the actual arrangement and the billed component together, including what the claim says about the service location.

Site approval has a date as well as an address. A later approval cannot supply billing privileges for earlier services. For an employee who scheduled patients at several locations, the appointment and staffing records can connect the site actually used to the enrollment record and the claim sent for payment.

Which Sleep Test Coverage Rule Applies to an Older Claim?

The applicable rule is the one governing that service date, payer, location and component. Medicare’s national decision established coverage for specified diagnostic sleep tests for dates of service beginning March 3, 2009. Before that change, coverage of the tests themselves had been left to local contractors.

TRICARE and the Federal Employees Health Benefit Program have their own payment terms. TRICARE’s sleep-study benefit page updated in October 2026 permits qualifying adult home testing for obstructive sleep apnea and requires a physician referral and supporting medical evidence. The older Sleep Solutions case concerned what those programs reimbursed during the conduct alleged there. A historical claim needs its historical payment terms, alongside the study and the bill.

Sleep Solutions and the Alleged Attendance Upgrade

Sleep Solutions supplied self-administered home sleep-study kits from Glen Burnie, Maryland. In September 2010, the Justice Department announced that the company had paid $500,000 to resolve False Claims Act allegations involving TRICARE and the Federal Employees Health Benefit Program. The alleged increase in reimbursement came from describing home studies as attended by a sleep technologist.

The Justice Department also alleged that Sleep Solutions billed those same home studies when the programs did not permit reimbursement for them. Sleep Solutions denied the allegations. For a billing employee, the case separates the description chosen for the test from the payer’s decision to cover that kind of test at all. We see the familiar bargain: a payment with the denial intact.

Coastal’s Owner Admitted Billing Home Tests as In-Office Studies

The Justice Department’s August 2026 account of the Coastal owner’s criminal guilty plea describes admitted overcharging for tests performed at home but billed as more expensive in-office studies. Coastal Diagnostic Testing Group and Coastal Diagnostic operated in Oregon. The criminal case was against their owner, who directed the businesses’ billing. The Health and Human Services and Veterans Affairs Offices of Inspector General investigated.

The criminal charging document separately alleged that the owner submitted or directed staff to submit claims using the attended-study codes, knowing they produced higher reimbursement than warranted. It described the in-office or laboratory studies in that case as billed and reimbursed at rates three to four times those of home studies. In the charging document’s account, the billing code supplied the attendance.

Bay Sleep’s Alleged Switch to Approved Locations

The Justice Department’s complaint against Qualium Corporation, doing business as Bay Sleep Clinic, alleged that the business enrolled only its Los Gatos and San Francisco locations as Medicare-approved independent diagnostic testing facilities. It alleged that patients nevertheless underwent sleep tests at other locations. The complaint describes what happened next:

The complaint alleged that leaving the other locations unenrolled prevented Medicare from conducting the required site inspections. It also described technicians calling the Los Gatos office each morning to learn which clinic to report to and recording their initials in study reports. Those details connect the day’s actual staffing and test location with the location claimed for payment.

The enrollment paperwork allegedly changed the staffing history too. In a July 2010 application, the complaint says Bay listed one technician’s certification as effective in 2004 although the technician obtained it in 2010. Another appeared with a 2006 effective date despite certification in April 2009. The dates on the application represented qualifications for earlier work.

In December 2016, the Justice Department announced a $2.6 million settlement covering allegations about testing sites, technician qualifications and equipment claims. The site allegation remains especially concrete for an insider: patients underwent tests in one place, while the payment claims represented another.

The Records That Connect the Study to Government Payment

The useful evidence connects the ordered test, the performed test and the paid claim. The treating evaluation and order identify the intended study. Device assignment, raw channels, timestamps, attendance and completion or failure status describe its performance. Scoring and interpretation records connect that recording to the report used for billing and treatment.

For a location mismatch, enrollment approvals and effective dates sit beside the appointment, device and staffing records. The submitted claim supplies the code, component, units and represented service location. Remittances, denials and corrected claims show what the payer did with those representations and what the provider later changed. An employee who knows who selected the code or substituted the site can explain how the discrepancy entered billing.

The report also travels into treatment. Medicare bars payment to a CPAP supplier when it or its affiliate provided the diagnostic sleep test, directly or indirectly, with an exception for attended facility-based polysomnography. That gives the attended-test description a financial consequence beyond the diagnostic bill. For an insider who knows both sides of the business, the actual test and the supplier relationship connect the report to the equipment payment.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. If you know how a home recording became an attended-study claim, or how an unapproved testing site disappeared from billing, that knowledge gives us a concrete starting point for assessing the case with you.

You Know Where the Patient Was

If the claims you handle describe attendance or a testing site that your work tells you was different, speak with our whistleblower experts about the mismatch. We work with you to build your strongest case around the actual study, the government payment and the decisions inside the business. We bring in healthcare fraud whistleblower lawyers who understand diagnostic billing and stay beside you through the process.
