PDAC Coding and Medicare Coverage: A Product Code Is Not a Promise of Payment

PDAC coding does not establish Medicare coverage, and fraud allegations can begin with the manufacturer’s sales pitch. In the BSN Medical case, the government alleged that the manufacturer promoted products under codes for which approval was missing or had expired. For an insider examining durable medical equipment billing, the question reaches beyond the code on the product sheet. A product can pass the coding review while the claim fails on something the coding contractor never decided.

What a PDAC Product Listing Actually Decides

The Pricing, Data Analysis and Coding contractor determines which HCPCS code a product falls under. The DME Medicare Administrative Contractors process claims and write coverage policies. Product classification and patient coverage answer different questions, even when both affect whether Medicare pays.

For some products, coding verification is an entry requirement. Negative-pressure wound therapy equipment and continuous glucose monitors have policies that make the contractor’s product designation a condition of payment.

Medicare uses different payment categories for equipment, including purchased items, capped rentals, frequently serviced equipment, oxygen, prosthetics and orthotics. A code can shape both the amount and the stream of revenue attached to an item.

An old approval becomes particularly consequential when a company continues promoting a code after that approval expires. The product’s coding history and the sales instructions can tell different stories.

What Is Covered Under Durable Medical Equipment?

Medicare coverage requires an item within a covered benefit category and a claim that meets the applicable coverage and documentation requirements. DMEPOS brings equipment, prosthetics, orthotics and supplies together for billing, but those products have different coverage rules.

A continuous glucose monitor illustrates the benefit-category question. For coverage under the durable medical equipment benefit, a component of the system must qualify as durable equipment. The receiver is that durable component; the rest of the system is billed through a separately coded supply allowance.

Wound dressings show why the patient’s condition matters alongside the product. The coverage policy requires a qualifying wound that was surgically created, surgically modified or debrided. Compression bandages and multilayer systems used without a qualifying wound fall outside that benefit. A product description can identify the dressing’s material. The patient’s medical record has to establish the wound that supports the claim.

Brace classification adds another distinction. Custom-fabricated, custom-fitted and off-the-shelf orthotics carry different requirements. An off-the-shelf brace requires only minimal self-adjustment and no expertise in fitting it to the individual. A code tied to fitting work puts the work actually performed inside the inquiry. A catalog description alone cannot tell us what happened when the supplier furnished the brace.

Does DME Require Prior Authorization?

Medicare requires prior authorization for selected durable medical equipment items. For items on the required list, an affirmative decision is a condition of payment. The patient’s claim still has an order, supporting documentation and delivery requirements of its own. We examine the authorization and the underlying claim together, including what information the supplier used to obtain the decision.

What Are the Documentation Guidelines for Durable Medical Equipment?

Durable medical equipment documentation requirements include a standard written order, the practitioner’s supporting medical records and proof of delivery, with additional requirements tied to the product. The supplier holds the documents supporting its claim. Their dates and contents matter as much as their presence in a folder.

An order signed after the brace shipped can expose a gap that a complete-looking file conceals. For selected items, the supplier must receive the written order before delivery, and obtaining it afterward does not cure that failure. We examine when the order reached the supplier alongside what it says.

The standard documentation requirements for claims submitted to DME MACs also reach delivery and refills. Where the refill rule applies, the supplier must document the patient’s affirmative response before shipment. We compare what the practitioner ordered, what the clinical record supports, what the supplier delivered and what it billed.

A PDAC-Listed CGM Product Is Not a Promise of Payment

A PDAC-listed CGM product does not mean Medicare will pay the claim because the beneficiary and the billed items must also meet the coverage rules. The product’s classification does not establish the patient’s diabetes treatment or history of hypoglycemia.

In April 2023, the glucose-monitor coverage policy removed the requirement for three or more daily insulin administrations and added a pathway based on a history of problematic hypoglycemia. Patient criteria include insulin treatment or a qualifying history of problematic hypoglycemia. That distinction sits in the medical record, regardless of how the monitor appears in the product list.

The claim also has to account for supplies billed alongside the monitor. A blood glucose monitor and supplies billed in addition to a non-adjunctive continuous glucose monitor are subject to denial. Reviewing only the receiver’s code misses the other claim lines.

There is a consequential exception for recurring supplies, too. The CGM supply allowances under A4238 and A4239 are exempt from the ordinary affirmative-contact refill requirement. A 90-day supply cap applies instead.

BSN Medical and the Missing Coding Approvals

BSN Medical agreed to a $785,672 settlement in August 2022 over allegations involving products marketed under codes without the required PDAC approval. The Charlotte manufacturer specialized in compression therapy, wound care and orthopedics.

The government alleged that, from January 2015 through December 2017, BSN marketed and promoted products that were not reimbursable because it had never obtained PDAC approval or because the approval had expired. The allegations concerned E2607, L0625 and L0626. A whistleblower brought the case, and the government investigated and joined it to complete the settlement.

The alleged conduct connected the manufacturer’s promotion of the products to the coding requirement. That is why the marketing material belongs beside the contractor correspondence. An employee who knows what the company told customers about billing may hold a different part of the story from the supplier who submitted the claim.

The product sheet and the coding decision have to describe the same permission for the same period.

Why the Product Page Is Not the Claim File

The physician’s order and the supplier’s bill can describe different equipment. The whistleblower’s complaint against Kinex Medical Company alleged that cold-therapy orders came bundled with unnecessary braces or slings. Medicare and the patient then faced separate bills for those components, according to the complaint. One patient example puts the discrepancy plainly:

The complaint also alleged that Kinex omitted the metal strut from a shoulder brace supplied to another patient. The inquiry reaches the physical item the patient received, alongside its name and code. Kinex later agreed to a $6,925,000 settlement announced in March 2026 over allegations involving medically unnecessary equipment and improper waivers of patient cost sharing.

Who furnished the equipment matters as well. HHS-OIG’s Medicaid Fraud Control Units Fiscal Year 2014 Annual Report, published in 2015, described a civil case involving back braces supplied by an excluded company. Another equipment company allegedly billed Medicare and Medicaid, passed part of the reimbursement to the excluded company and used false invoices to support the billing. The alleged arrangement put false invoices between the actual supplier and the health care programs paying for the braces.

These examples put different records in view. The order shows what the practitioner requested. The delivery record shows what reached the patient. The invoice can show who actually supplied it. Together, those records test the story the billing code tells.

What Happens If DMEPOS Billing Is Improper?

Knowingly false equipment claims can lead to a False Claims Act case. We examine what the business knew and what it told the government or the suppliers submitting claims.

The decisions inside the company matter: promoting an expired approval, billing a different item from the one ordered, or using an invoice that conceals who furnished the equipment. An insider may know who gave those instructions and whether billing continued after the problem was raised.

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