Medicare’s Diabetic Shoe Benefit Is Narrow, and Missing Records Drive Most Wrong Payments

Medicare does cover therapeutic shoes for some people with diabetes, but many denied claims fail for the same reason: the paperwork is incomplete, not the shoes.

Learning that Medicare may pay for diabetic shoes can sound like one less cost to handle. But a diabetes diagnosis by itself does not guarantee coverage for a pair.

Picture Carol, a 68-year-old retired bookkeeper with type 2 diabetes and Original Medicare. After a neighbor tells her about the benefit, she gets fitted for extra-depth shoes and inserts and expects Medicare to cover part of the bill. Instead, the claim is denied and the supplier bills her directly.

The most important issue is documentation. The Centers for Medicare & Medicaid Services (CMS) says inadequate paperwork caused 85.5% of improper payments for diabetic shoes in the 2024 reporting period. To qualify, Carol needs more than diabetes alone; she must also have a specific foot condition, along with medical records and a certification that meet Medicare’s timing rules.

Diabetes Alone Is Not Enough

Medicare.gov’s page on therapeutic shoes and inserts lists two medical requirements. She must have diabetes, and she must also have severe diabetes-related foot disease. If her feet are otherwise healthy, she does not qualify.

CMS says the certifying doctor must document at least one of the following:

• Previous amputation of the other foot, or part of either foot
• History of foot ulcer
• History of pre-ulcerative calluses
• Peripheral neuropathy with evidence of callus formation
• Foot deformity
• Poor circulation

If Carol has numb feet but no documented calluses, neuropathy by itself would not satisfy the rule. She would need another qualifying condition from the list. The doctor treating her diabetes must either document the qualifying foot problem or review and sign off on another qualified clinician’s findings before certifying her need for shoes.

Her Diabetes Doctor Must Certify the Need

The second requirement focuses on who signs the paperwork. The doctor managing her diabetes must certify three things: that she meets the standard, that she is under a comprehensive diabetes care plan, and that she needs the shoes.

CMS also sets strict timing requirements. That doctor must see her in person for diabetes care within 6 months before the shoes are delivered. The certification statement must also be signed within 3 months before delivery. A visit from the previous winter could easily fall outside those limits if the fitting happens in the fall.

A podiatrist or another qualified clinician writes the prescription. That could include a nurse practitioner or physician assistant, and the diabetes doctor can do it as well. The clinicians and the supplier must be enrolled in Medicare. Enrollment and accepting Medicare’s approved rate are separate matters, so Carol needs to confirm both.

What the Annual Benefit Actually Pays For

Once she qualifies, Medicare covers one of the following each calendar year, depending on her needs:

• One pair of extra-depth shoes plus 3 pairs of inserts
• One pair of custom-molded shoes, including inserts, plus 2 extra pairs of inserts, if a foot deformity prevents her from wearing extra-depth shoes

Her costs follow standard Part B rules. After she meets the annual Part B deductible, she pays 20% of the Medicare-approved amount if the supplier accepts assignment. If the supplier does not accept assignment, it can charge more, and she would be responsible for any amount above Medicare’s approved payment.

Paperwork Is Where Problems Start

A signed certification is not enough on its own. The medical record must back it up, including the foot condition that makes her eligible. A checked box cannot replace exam notes.

Three steps can help protect Carol’s claim:

1. Check whether her medical records show a qualifying foot condition. If a podiatrist or another clinician examined her feet, make sure those notes are sent to the diabetes doctor for review and approval.
2. Confirm that the clinicians and the supplier are enrolled in Medicare. Ask the supplier whether it accepts assignment, meaning it agrees to Medicare’s approved rate.
3. Work backward from the delivery date. The diabetes visit and foot exam must have occurred within the prior 6 months. The certification must follow the required visits and record review and be signed within the prior 3 months. Ask the supplier to verify the dates before delivery.

If Medicare has already denied the claim, Carol should review her Medicare Summary Notice for the reason, the amount she may owe, and appeal instructions. A denial does not automatically make her responsible for the entire supplier bill. She should ask the supplier to review what it submitted and gather the medical records supporting the claim without missing the appeal deadline.

Medicare’s shoe benefit begins with diabetes, but payment depends on whether her feet meet the medical criteria and the paperwork proves it, with every signature dated within the required window. For Carol, the records come first and the fitting comes second.
