Diabetic Shoe Paperwork, Right the First Time

The Most Common Reason Diabetic Shoe Claims Fail

Insufficient documentation accounts for 86% of improper payments for diabetic shoes. Not medical necessity. Not coding. Paperwork.

That is why we ask, and it is why we would rather ask early. Everything on this page comes from Medicare policy, with links below.

2 roles, 2 signatures

The written order can come from a podiatrist, PA, NP, clinical nurse specialist, or any MD or DO. The certification statement must be signed by the MD or DO who manages the patient’s diabetes.

6 months, 3 months

Both in-person visits must fall within six months of delivery. The certification statement must be signed on or after those visits and within three months of delivery.

1 of 6 specific foot conditions

A diabetes diagnosis alone does not qualify the patient. The condition must be one of six named in the policy, and it has to be described in the record.

In the medical record

Medicare states directly that the certification statement does not satisfy the medical record requirement. The chart needs the qualifying foot condition and the diabetes management, separately.

The Detail and Supporting Sources

Who can sign what?

Certifying physician

An MD or DO responsible for diagnosing and treating the patient’s diabetic systemic condition under a comprehensive plan of care. A podiatrist cannot serve in this role. Neither can a clinical nurse specialist.

An NP or PA may serve only “incident to” a supervising physician, and only if all three of the following are true: the supervising physician has documented that the patient is diabetic and under a comprehensive management program; the NP or PA certifies that the shoes are part of that treatment plan; and the supervising physician reviews, signs, and dates the NP or PA notes pertaining to the shoes.

Prescribing practitioner

The standard written order may come from the certifying physician, a different MD or DO, a PA, an NP, a clinical nurse specialist, or a podiatrist – whoever writes the order must be knowledgeable in fitting diabetic shoes and inserts.

What the certification statement must say:

Signed and dated by the certifying physician, stating that the patient has diabetes mellitus; has at least one of the qualifying foot conditions; is being treated under a comprehensive plan of care for the diabetes; and needs therapeutic shoes.

What qualifies the patient?

The patient must have diabetes mellitus, plus at least one of the following:

Amputation of the other foot, or part of either foot
History of foot ulceration of either foot
History of pre-ulcerative calluses of either foot
Peripheral neuropathy with evidence of callus formation of either foot
Foot deformity of either foot
Poor circulation in either foot

What does not qualify on its own:

hypertension, coronary artery disease, congestive heart failure, or the presence of edema. Documentation needs to include objective, quantifying information, for example pedal pulses, or a finding that clearly pertains to the foot.

Two paths to satisfy this.

The certifying physician either documents the finding personally, at an in-person visit within six months before delivery and on or before the date they sign the certification. Or they adopt another clinician’s note.

Can I use another clinician’s exam?

Yes. And if you did not write the order, you do not need to perform your own foot exam. In fact, a podiatrist’s foot exam is often the strongest documentation in the chart, and the certifying physician may rely on it.

This is an often-misunderstood part of the policy, and it makes the process considerably lighter for a primary care office. When a podiatrist or another practitioner documents a qualifying condition and writes an order, you can rely on their record. Your notes are not required to match theirs.

The sequence is what matters:

Obtain the record of the in-person visit
Sign and date it
Indicate on the record your agreement with the information in it
Sign the certification statement

The initials, date, and agreement go on the practitioner’s record you obtained, not on the certification statement. Annotating that record is what brings it into your chart, which is what satisfies the requirement. Notes from a podiatrist, another MD or DO, a PA, an NP, or a CNS are all eligible.

How long is the paperwork valid?

Three dates count backward from the delivery date.

Visit where the diabetes was managed, with the certifying physician – no more than six months before delivery.
Visit where the foot condition was documented, often the same visit but can be a different practitioner – no more than six months before delivery.
Certification signature, on or after these visits – no more than three months before delivery.

The written order carries its own rule. It must be dated on or after the in-person visit with the practitioner who wrote it.

Watch this common pitfall. If the diabetes visit happens more than three months before delivery, you cannot sign the certification at that visit. It would be older than three months by the time the shoes get fitted, and the claim fails even though every word in it is correct. Hold the certification and sign closer to delivery. Ask us for the delivery date before you sign, because the patient schedules that date directly with us.

Recertification. A new certification statement is required for anything provided more than one year after the most recent one on file.

Replacements. A new order is not required to replace an insert or a modification within a year of the order on file. Replacing a shoe always requires a new order. Both windows count backward from the delivery date.

What we handle

Before anything is delivered, we complete the in-person evaluation, document the foot abnormalities which the shoes or inserts need to accommodate, take the measurements, and scan, cast, or take impressions for custom-molded items. At delivery we conduct an in-person evaluation with the patient wearing the shoes and inserts, before documenting fit.

We review every packet against the policy before it goes out. If something is missing, we would rather ask you once, early, than send an addendum request after the fact.
