Medicare covers one diabetic foot exam every six months under Part B, as long as you have a diagnosis of diabetic peripheral neuropathy with loss of protective sensation. That’s the baseline, but the rules shift depending on your specific foot condition, and some patients qualify for more frequent visits.
The Six-Month Rule for Foot Exams
The standard schedule is one foot exam every six months with a podiatrist or other foot care specialist. This coverage has been in place since July 2002 and applies specifically to people with documented diabetic sensory neuropathy and loss of protective sensation (LOPS). There’s one important catch: if you see a foot care specialist for any other reason between those scheduled visits, Medicare won’t cover the next routine exam on the six-month timeline. The clock essentially resets.
To qualify, your provider needs to confirm LOPS through a specific nerve test using a thin filament pressed against five spots on the bottom of each foot. If you can’t feel the filament at two or more of those five sites on either foot, that meets Medicare’s threshold for the diagnosis. This test result must be documented in your medical record.
When Medicare Covers More Frequent Visits
Some patients qualify for visits more often than every six months. Medicare may cover additional foot care if you’ve had a non-traumatic amputation of all or part of your foot, or if your feet show visible changes that signal serious foot disease. In these cases, your provider can justify more frequent visits based on medical necessity.
Separately, routine foot care services like nail trimming, corn removal, and callus treatment follow a different frequency rule. When these services are covered (more on that below), Medicare considers them medically necessary once every 60 days. If your provider bills for them more often than that, the claim will be denied.
Routine Foot Care Is Not Automatically Covered
This is where many people get confused. Medicare normally excludes what it calls “routine” foot care: trimming nails, removing corns and calluses, soaking feet, and applying skin creams. For most people, these services are an out-of-pocket expense regardless of how often they’re done.
However, Medicare makes an exception when a systemic condition like diabetes causes severe circulatory problems or reduced sensation in your feet. In those cases, routine procedures like nail care and callus removal become covered because having a non-professional do them could be dangerous. Your provider must document the systemic condition and explain why professional care is necessary.
Fungal toenails (mycotic nails) can also qualify for coverage without a systemic condition, but only when the thickened, damaged nail is causing pain, limiting your ability to walk, or leading to secondary infection. Your provider needs to document both the clinical evidence of the fungal infection and the functional impact it’s having.
What Happens During a Covered Visit
A covered diabetic foot exam typically includes a sensory evaluation, inspection for wounds or skin changes, assessment of blood flow, and treatment of any problems found during the exam. If your provider discovers an ulcer, wound, or infection during a routine visit, the diagnosis and treatment of that problem is covered separately from the routine exam itself. These medically necessary services aren’t limited to the six-month schedule since they fall outside the “routine care” category entirely.
Therapeutic Shoes and Inserts
Medicare also covers therapeutic footwear for people with diabetes, but with strict annual limits. Each calendar year, you can receive one pair of extra-depth shoes and three pairs of custom inserts (not counting the standard inserts that come with the shoes). Your prescribing physician must certify that you need therapeutic footwear as part of a comprehensive diabetes treatment plan.
Your Costs for Covered Foot Care
Diabetic foot care falls under Medicare Part B, which means standard cost-sharing applies. You’ll pay 20% of the Medicare-approved amount after meeting your annual Part B deductible. If you have a Medigap or Medicare Advantage plan, your supplemental coverage may reduce or eliminate that coinsurance. Medicare Advantage plans must cover at least what Original Medicare covers, though they may use different provider networks or require referrals.
How to Make Sure Your Visits Are Covered
The most common reason for denied claims is missing documentation. Before your appointment, confirm that your medical record includes a diabetes diagnosis, a documented LOPS evaluation with monofilament testing results, and a note explaining why professional foot care is medically necessary. Your primary care provider or endocrinologist typically establishes this documentation, and your podiatrist references it when billing.
Keep track of when your last covered foot exam was. If you schedule a visit at five months instead of six, or if you saw a foot specialist in between for a separate issue, your claim may be denied. Timing matters with Medicare’s coverage rules, and a visit that’s even a few days early can result in you paying the full cost out of pocket.
