DPM stands for Doctor of Podiatric Medicine. In the United States a podiatrist with those letters is a physician: four years of undergraduate study, four years of podiatric medical school, then a surgical residency. They diagnose, they write prescriptions, and they operate on the foot and ankle.
The question behind most searches for DPM vs MD is simply whether this person is a real doctor. They are. The training is a parallel track, not a shorter one.
How does DPM training compare to MD training?
Structurally it runs alongside. The DPM podiatry degree is a four-year professional doctorate, sat after an undergraduate degree and followed by residency, which is the same shape as the MD route. Podiatric medical school covers the same basic sciences and then specialises early and hard into the lower limb, which is where the paths separate.
Residency is where a DPM becomes surgical. Three years is the standard, in hospitals, alongside residents from every other service. The difference from an MD is scope, not depth: a DPM's licence covers the foot and ankle, and within that area they do the medicine and the surgery both.
Is a podiatrist a real doctor?
Yes. They are licensed physicians whose scope is defined anatomically rather than by specialty in the usual sense. State law sets the outer edge of that scope, and it is not identical everywhere, particularly around how far up the leg surgical privileges extend.
The practical version for a patient: a podiatrist can order imaging, prescribe medication, perform a nail procedure or a bone procedure, and manage a foot problem from first appointment to end without referring you anywhere else.
What is the scope of a DPM?
The foot and the ankle, and everything medical or surgical inside that boundary. DPM podiatry scope is drawn anatomically instead of by specialty, so within the lower limb a podiatrist covers diagnosis, imaging, prescribing, nail and skin procedures, and bone and soft tissue surgery.
The edges are set by state law and they are not identical from one state to the next, mostly around how far above the ankle surgical privileges reach. If that matters for your case, the practice will tell you plainly, and the state board publishes the wording.
Is DPM different from a chiropodist?
Chiropodist is not an American title. If you have run into it, you were almost certainly reading Canadian or British material.
In Ontario it is a distinct regulated profession with its own college, sitting between a nurse and a podiatrist in scope. Elsewhere in Canada the word podiatrist is used much as it is in the US. We cover the Canadian arrangement in what a foot care nurse does in Canada and in our guide to what a chiropodist is.
So who does routine nail care in the US?
Three different people, and they are not interchangeable.
The podiatrist. Diagnosis, procedures, prescriptions, surgery, and routine nail and callus care too, particularly for patients where a small foot problem is not a small problem.
The foot care nurse. A smaller field in the US than it is in Canada, but a real one, with its own national association. A licensed nurse who has added foot care training and works on nails, calluses and skin, often in long-term care or in patients' homes. That house-call model is a business in its own right, and we have written up how to start a mobile foot care business for anyone weighing it up.
The nail technician. A cosmetology licence, not a medical credential. Most states restrict work to healthy, intact nails and prohibit diagnosis of any kind. A salon is not a substitute for either of the two roles above, and a good technician will be the first to say so and send you on.
Podiatrist or dermatologist for a toenail problem?
Either can help, and which is faster usually comes down to who can see you. A podiatrist works on that anatomy all day and can reduce a thickened nail in the same visit. A dermatologist brings a broader skin and nail differential, which matters when the question is whether it is fungal at all.
Not everything that looks fungal is. Psoriasis, old trauma, lichen planus and a plain bruise all imitate it. Our guides to telling toenail fungus apart from injury, psoriasis and bruising and to nail fungus versus nail psoriasis go through the differences.
For what happens once you are in the chair, we have a separate piece on what podiatrists recommend for toenail fungus.
Does Medicare cover routine foot care?
Generally no, and the exception is narrower and more specific than most people are told. This is the single most misunderstood thing about seeing a podiatrist in the United States, so it is worth reading the actual wording rather than a summary of it.
The exclusion. Federal regulation at 42 CFR 411.15(l) excludes "routine foot care, such as the cutting or removal of corns, or calluses, the trimming of nails, routine hygienic care (preventive maintenance care ordinarily within the realm of self care), and any service performed in the absence of localized illness, injury, or symptoms involving the feet". In other words, turning up to have healthy nails cut is not a covered benefit.
The exception people mean when they say "but I'm diabetic". It is not written around diabetes by name. It is written around severity. A Medicare Administrative Contractor policy, LCD L33636, Routine Foot Care and Debridement of Nails, states it directly: "Medicare payment may be made for routine foot care when the patient has a systemic disease, such as metabolic, neurologic, or peripheral vascular disease, of sufficient severity that performance of such services by a nonprofessional person would put the patient at risk." The same document adds that the findings have to be documented in the record.
Two details almost nobody mentions. The regulation says plainly that "treatment of warts is not excluded". And it puts a clock on nails: treatment of mycotic toenails "may be covered if it is furnished no more often than every 60 days or the billing physician documents the need for more frequent treatment".
⚠ Read that 60-day line next to the growth rate further down this page and you have the whole shape of the problem. A nail that is reduced every two months is a nail being managed, and the eight weeks in between are not covered by anything.
Before you rely on any of it: an LCD is a contractor policy for a defined region, not a nationwide rule, and coverage also differs between Original Medicare, Medicare Advantage and commercial plans. We are not a billing resource and there are no codes on this page. Ask the clinic's front desk before the appointment rather than after. They deal with this daily and will tell you how your visit is likely to be coded.
Why the same nail keeps coming back
A procedure or a reduction changes the nail on the day. What it does not change is the environment the foot spends the next six weeks in.
StatPearls notes that the risk of tinea infections is elevated with excessive sweating and that occlusive shoes worn for extended periods predispose patients to dermatophyte infections. Gupta and Versteeg, in JAPMA, put recurrence and relapse for superficial fungal infections of the feet at 10% to 53%. And nails grow at roughly 1.62mm per month (Yaemsiri and colleagues, JEADV 2010), so a full toenail takes the better part of a year to replace itself.
Put those three together and the pattern is obvious. The appointment is a reset. The shoe is the environment. Only one of the two gets any attention, and it is not the shoe.
What a home routine is for
IodinePure EZ Clear Nails is built around a soak rather than a paint, because a soak carries solution under the free edge and around the nail folds, which is precisely where a brush stops. Two ingredients, iodine and distilled water. Water-based, so no alcohol, no sting and no brown stain. Listed with Health Canada as a cosmetic and carried by more than 200 foot care clinics across North America.
Who this is not for: anyone with a painful, lifting or separating nail, a dark streak running from cuticle to tip, or diabetes with reduced sensation. Those are appointments, not routines, and they come first.
For US podiatry practices
The pitch to a DPM is not a clinical claim, and we would not make one to a physician. It is a take-home product that is cosmetic, has no drug claims attached to it, does not sting or stain, and is simple enough that patients still do it in week eight. It also lands squarely in the gap the 60-day rule creates. Partner practices earn a commission on what their patients buy at home, including recurring commission on subscriptions, rather than a discount on inventory they carry.
Chairside guidance is in how to use IodinePure in your clinic, there is a printable after a nail procedure take-home sheet, and the terms are on the For Clinics page.
Frequently Asked Questions
What does DPM stand for?
Doctor of Podiatric Medicine. It is the degree held by podiatrists in the United States, earned over four years of podiatric medical school after an undergraduate degree, and followed by a surgical residency.
Is a DPM the same as an MD?
Both are licensed physicians and both complete a four-year doctorate plus residency. The difference is scope: a DPM's licence covers the foot and ankle, and within that area they practise medicine and perform surgery. State law sets the exact boundaries.
Is a podiatrist a real doctor?
Yes. A podiatrist can order imaging, prescribe medication and perform surgery on the foot and ankle, and can manage a foot problem from first visit to resolution without referring out.
Does Medicare cover routine foot care?
Generally no. Federal regulation excludes routine foot care, including the cutting or removal of corns or calluses and the trimming of nails, where there is no localized illness, injury or symptoms involving the feet. A Medicare contractor policy allows payment where the patient has a systemic disease, such as metabolic, neurologic or peripheral vascular disease, of sufficient severity that care by a nonprofessional person would put the patient at risk, with the findings documented. Rules differ by contractor and by plan, so ask the clinic's front desk before your appointment.
How often will Medicare pay for mycotic toenail treatment?
The regulation says treatment of mycotic toenails may be covered if it is furnished no more often than every 60 days, or where the billing physician documents the need for more frequent treatment. The regulation also states that treatment of warts is not excluded. Coverage still depends on your plan and your contractor.
Should I see a podiatrist or a dermatologist for toenail fungus?
Either works, and availability often decides it. A podiatrist can reduce a thickened nail in the same visit. A dermatologist brings a wider skin and nail differential, which helps when it is not clear the problem is fungal at all.
Can a nail technician treat toenail fungus?
No. Nail technicians hold a cosmetology licence rather than a medical one, and most states limit them to healthy, intact nails and prohibit diagnosis. A technician who spots something and refers you on is doing their job correctly.
