Durable Medical Equipment Advance Determination of Medicare Coverage: What the Reviewer Saw and What the Supplier Billed

When a supplier with an affirmative ADMC decision still faces a claim denial, we examine the decision’s stated scope, the information submitted for review and the later claim. An insider may know something the reviewer did not: who changed the prescription, where the clinical account came from or whether the supplier delivered what it billed. An altered prescription can make a sales decision look like a medical one.

Medicare separates ordering equipment from paying the supplier. The practitioner signs the order. The supplier holds the order and supporting medical documentation, maintains proof of delivery and submits the claim. We compare those records with the review decision, keeping the particular review process and the particular item in view.

What an Affirmative ADMC Decision Covers

An advance determination of Medicare coverage is voluntary. Before delivery, a supplier or the beneficiary can ask the Medicare contractor that handles equipment claims whether a customized item will meet Medicare’s medical-necessity requirements. Neither has to ask before submitting a claim, and Medicare’s program-integrity contractors may not require a request first. Under the Program Integrity Manual’s ADMC rules, the item must be customized, meaning uniquely constructed or substantially modified for one beneficiary on the treating physician’s description and orders, and it cannot be an inexpensive item. The contractors publish examples each year, as billing codes for the categories of eligible items.

The request carries enough of the patient’s medical record to identify the patient, the intended use and the condition that requires a customized item. The contractor decides whether the documentation supports medical necessity and checks the beneficiary’s claims history for any other reason a claim would be denied, such as the same or similar equipment already provided. It answers in writing within 30 calendar days. Because no payment has been requested, the decision cannot be appealed.

An affirmative ADMC decision assures the supplier and the beneficiary that, on the information submitted, the beneficiary meets Medicare’s medical-necessity requirements for the item. It lasts six months: the item must reach the beneficiary within six months of the decision. It does not assure that the beneficiary meets Medicare eligibility requirements or that any other Medicare requirement has been met, and it does not extend to the price Medicare will pay.

Why Can an Affirmative ADMC Decision Be Followed by a Claim Denial?

Only a complete claim lets the contractor make a full determination. Eligibility, other Medicare requirements and the price remain open after an affirmative decision, and an item delivered more than six months after the decision falls outside it. The contractors also keep the right to review claims before or after payment and to deny them when they determine that the affirmative decision rested on incorrect information.

That last limit is where an insider’s knowledge counts. If the clinical account in the request was altered or assembled inside the supplier, the favorable decision does not stop the contractor from denying the claim. We compare the request file with the practitioner’s own records, the item delivered and the claim.

Customized Durable Medical Equipment Is Priced Individually

Under the Medicare law’s equipment payment rules, customized durable medical equipment has no fee-schedule amount. The contractor determines a lump-sum payment through individual consideration. How the supplier describes the item matters to what Medicare pays.

Medicare divides durable medical equipment into payment categories. The Centers for Medicare & Medicaid Services assigns items to those categories through program instructions. The categories include customized items, frequently serviced equipment, oxygen equipment and capped rentals. A supplier’s product description and the category used for billing belong beside each other when we examine a claim.

For an insider handling a customized item, we want to understand what the request described, what the supplier furnished and how the requested price was presented.

Does DME Require Prior Authorization?

Unlike ADMC, required prior authorization is not voluntary. Selected durable medical equipment items require prior authorization as a condition of Medicare payment. The Centers for Medicare & Medicaid Services identifies them on the Required Prior Authorization List. Its July 2026 notice distinguishes that list from the larger Master List and the separate Required Face-to-Face Encounter and Written Order Prior to Delivery List.

The Master List identifies potential review targets. The required lists and their effective dates determine which extra requirements apply.

For required prior authorization, the requester submits the order, relevant medical records and supplier documentation before furnishing the item and submitting the claim. The reviewer communicates a provisional affirmation or non-affirmation.

Why Can Required Prior Authorization Be Followed by a Claim Denial?

Under the required prior-authorization program, an affirmative decision is provisional because information available only after claim submission can still produce a denial. The Centers for Medicare & Medicaid Services gives a duplicate claim as an example in its November 2019 final rule. The reviewer can assess the submitted material before delivery, while a later claim raises a payment question that the earlier review could not resolve.

The same rule limits reviewers to the documentation submitted with the request. That documentation must support the medical necessity of the related options, supplies or accessories for which payment is sought. A replacement item requires its own medical-necessity support.

That distinction gives an insider a concrete comparison. We look at the equipment described in the request beside the equipment and accessories on the bill. We also examine the clinical material the reviewer received alongside the practitioner’s underlying records. The useful evidence is the difference between those documents and who was responsible for it.

What Are the Documentation Guidelines for Durable Medical Equipment?

Medicare requires a written order and supporting medical documentation, while the supplier also maintains proof of delivery. The order must identify the patient and the item, carry a date and be signed by the practitioner.

For a health care supplier, the order date matters. For power mobility devices and other items on the required face-to-face and written-order list, the supplier must receive the order before delivery. For other durable medical equipment, the order must reach the supplier before claim submission. The CMS documentation policy says that, where an order before delivery is required, obtaining it afterward does not cure the claim.

For someone inside a supplier, the original order, the copy sent for review and the version retained for billing can therefore be important together. A changed date can alter the apparent sequence. A changed description can alter the medical-necessity story. We examine who created each version and how it reached the next person in the chain.

Orbit Medical Shows Why the Earlier Version Matters

Orbit Medical and Rehab Medical agreed to a $7.5 million civil settlement in May 2015 over alleged false claims for power wheelchairs. In the Justice Department’s account of the settlement, the alleged changes reached both the clinical explanation and the apparent origin of the paperwork. The two former employees who brought the whistleblower case were to receive approximately $1.5 million of the recovery.

The government alleged that Orbit sales representatives changed dates on prescriptions and chart notes, changed prescriptions to falsely establish medical necessity, created or altered chart notes and forged physician signatures. They also allegedly added fax stamps so documents appeared to have come from a physician’s office.

The fax stamp matters. It could make a supplier’s altered paperwork appear to be a doctor’s communication. Medicare was among the federal health care programs billed on those allegedly false records. The government alleged manipulation of the very records used to explain why the patient needed the equipment and when the prescribing work occurred.

Someone inside a healthcare supplier can know how an apparently complete medical file was assembled. That knowledge lets us examine the documents the reviewer saw against the work that actually produced them.

What an Insider Can Connect

An insider can connect the paperwork submitted for review to the decisions made inside the supplier. We examine the original clinical record, the submitted copy, the decision letter, the delivery record and the claim as parts of the same transaction. The person who knows why a date, signature or description changed may supply the connection that a finished billing file conceals.

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

When You Know What Changed

If you have seen a supplier rely on a favorable review while changing the records behind its claim, speak with our whistleblower experts about what the reviewer never saw. We work with you to connect those changes to the billing, bring in Medicare fraud whistleblower lawyers who understand durable medical equipment documentation, and stay beside you through the case.
