Diabetic Shoe Certification Fraud: Who Certifies, Prescribes and Fits

Diabetic shoe certification fraud uses false statements about a patient’s eligibility or fitting to obtain Medicare payment for therapeutic shoes and inserts. False certifications can leave patients without properly fitted footwear while Medicare pays the supplier. The diabetes chart, prescription and fitting record can pass through different hands. If you work in a physician’s office or for a shoe supplier, you may know what happened before the signed form reached billing.

Medicare pays for therapeutic footwear through a separate Part B benefit, and the contractors that handle durable medical equipment process the claims. The benefit connects health care to a physical product. A physician establishes the patient’s eligibility, a practitioner orders the footwear and a supplier selects and fits it. Each part of that work leaves its own evidence.

Who Certifies, Prescribes and Fits Diabetic Shoes?

For diabetic shoes, the certifying physician, prescriber and fitter have different roles, even when the same person performs more than one of them. The distinction matters because the person selling the shoes may also write the order, while someone else is responsible for the medical certification.

The certifying physician is the MD or DO responsible for diagnosing and treating the patient’s systemic diabetes through a comprehensive plan of care. That physician certifies the diabetes, the qualifying foot condition and the need for diabetic shoes. A podiatrist or clinical nurse specialist cannot serve as the certifying physician.

The prescribing practitioner writes the order. This can be a podiatrist, MD, DO, physician assistant, nurse practitioner or clinical nurse specialist. The supplier is the person or business that furnishes the footwear, including the required evaluation and fitting.

The prescriber may also be the supplier. A podiatrist can therefore prescribe and furnish the shoes, with the diabetes physician providing the certification. The certifying physician may also supply the footwear when practicing in a defined rural area or health professional shortage area.

What Documentation Connects the Certification to the Shoes?

The medical record, certification, prescription and supplier’s evaluations connect the patient’s condition to the shoes Medicare pays for. Under the Centers for Medicare & Medicaid Services’ therapeutic-footwear requirements, the patient must have diabetes and at least one qualifying foot condition documented in the medical record:

• Previous amputation of the other foot or part of either foot.
• A history of foot ulceration.
• A history of pre-ulcerative calluses.
• Peripheral neuropathy with evidence of callus formation.
• Foot deformity.
• Poor circulation in either foot.

The physician must also certify that the patient is receiving diabetes treatment under a comprehensive care plan and needs diabetic shoes. The condition on the form has to come from the medical record. The agency expressly says that the certification statement alone does not satisfy that requirement.

The diabetes-management visit and the foot examination supporting eligibility must be in person and within six months before delivery. The certification must be signed on or after the diabetes-management visit and within three months before delivery.

The certifying physician can document the foot condition personally, no later than the day of signing the certification. Alternatively, the physician can obtain, initial, date and agree with another practitioner’s examination record before signing. That examination may come from a podiatrist, another physician, a physician assistant, a nurse practitioner or a clinical nurse specialist.

For someone in a physician’s office, this is where the chart and the request for a signature meet. The useful comparison is the condition the certification describes against the examination that supports it. We work through that comparison with insiders who know how the office received, reviewed and signed the documents.

The Supplier Has Work Before Selection and at Delivery

The supplier must conduct and document an in-person evaluation before selecting the specific footwear. At delivery, it must objectively assess the fit of the shoes and inserts and record the results. The patient’s statement that the shoes feel fine cannot, by itself, serve as the fitting record.

The product matters to that assessment. Depth shoes provide space for inserts, while custom-molded shoes are constructed over a model of the patient’s foot. Inserts may be molded to the foot or a model, or carved from a patient-specific electronic model. The fit assessment concerns the shoes and inserts actually delivered.

When the Insert Does Not Match the Claim

A patient’s eligibility and a signed certification do not establish how an insert was manufactured. Custom-insert billing raises a separate question for the people making, purchasing and billing the product: did the fabrication match the claim?

Dia-Foot and its chief executive agreed to a $5,538,338 civil settlement, announced in January 2022, over allegations that the company sold custom diabetic-shoe inserts that did not meet Medicare’s custom-fabrication standards. The alleged conduct ran from 2013 through 2018. A former Dia-Foot employee brought the whistleblower case.

For a manufacturing or purchasing insider, the insert’s production history can answer a question the physician’s chart cannot. The medical record explains why the patient qualifies. The fabrication evidence explains what the supplier provided. Billing custom work while furnishing an off-the-shelf product moves the false statement from the patient’s condition to the product itself.

When a Fitting Certification Covers Work Nobody Did

A whistleblower’s complaint against Oxygen Plus alleged that the company sold diabetic shoes and inserts to Medicare and Medicaid beneficiaries without properly fitting them. It described periods when the company continued selling the footwear without a certified shoe fitter on staff, then alleged a paid arrangement for signatures:

The allegation makes the fitting record a question about the supplier’s actual work. Staffing records can show who was available to fit patients. Appointment and fitting records can show what the supplier says happened. A payment arrangement for signatures connects the document to the person allegedly paid to produce it.

For an employee who knows which patients were seen and who fitted their shoes, those are concrete comparisons. We examine them alongside the claims and the people who directed the work. The fitting certification is supposed to record an assessment of the product on the patient.

An Annual Benefit With an Annual Certification

Medicare’s annual benefit covers a pair of depth shoes or custom-molded shoes, with inserts. A new certification statement is required annually.

The depth-shoe category reached 220,231 beneficiaries through 6,136 supplier billing identifiers in the 2024 Medicare data. That is a substantial supply business built around a recurring patient relationship. Each year’s certification has to support that year’s footwear.

In its therapeutic-shoe audit announcement, the HHS Office of Inspector General reported that Medicare paid more than $143 million for therapeutic shoes and inserts across 2024 and 2025. The review, announced in May 2026, asks whether supplier payments met Medicare requirements. Its stated concern is insufficient documentation supporting the payments.

What Happens If DMEPOS Billing Is Improper?

Medicare can recover a therapeutic-shoe payment when the required certification is incomplete. The Centers for Medicare & Medicaid Services gives a specific example involving a shoe modification: the supplier produced a correctly coded written order and proof of delivery, but the treating practitioner’s medical record lacked complete certification. The review contractor classified the claim as an insufficient-documentation error, and the Medicare contractor recouped the payment.

The order was there. The delivery evidence was there. The missing certification still determined the payment outcome.

For the 2024 reporting period, CMS reported a 47.1% improper-payment rate for diabetic shoes. Insufficient documentation accounted for 85.5% of those improper payments. For an insider describing deliberate false certification, the question goes further: what did the document claim happened, who knew otherwise and how did that document reach a Medicare claim?

Diabetic Shoe Fraud Evidence Lives on Both Sides of the Handoff

The strongest account connects the clinical record to the supplier’s work and the claim. A healthcare employee may know what the physician actually examined. A fitter may know whether a patient attended. A manufacturing employee may know whether the insert came from patient-specific work or off-the-shelf stock. Together, those observations can explain a discrepancy that looks like a completed file to someone seeing only the forms.

The patient’s account matters too. In a Los Angeles-area criminal trial, beneficiaries testified that they had been promised diabetic shoes and other items in exchange for their Medicare numbers but never received them, according to the Justice Department’s account of the testimony. What a patient was promised and what arrived can expose another break in the transaction.

Federal investigators have also examined the manufacturer side. In the House Ways and Means Committee’s 2003 hearing, Waste, Fraud, and Abuse, the Justice Department described Operation Headwaters, an undercover investigation targeting manufacturers in diabetic footwear and other equipment categories. The FBI posed as a national medical-equipment distributor. The inquiry reached the businesses supplying the products, beyond the final billing office.

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