October 28 Is Coming: Is Your DME Business Ready for Medicare’s New Prior Authorization Rules?
Jennifer Wheeler, CPC, CPB, CPMA, AAPC Approved Instructor | DME Revenue Cycle Management Insights
For Durable Medical Equipment (DME) suppliers, October 28, 2026, is more than another date on the calendar. It marks an important expansion of Medicare’s prior authorization requirements—and suppliers who are unprepared could face preventable denials, reimbursement delays, and disruptions to cash flow.
The Centers for Medicare & Medicaid Services (CMS) is expanding its Required Prior Authorization List to include additional orthoses, pressure-reducing support surfaces, and manual wheelchairs.
For DME businesses already managing complex documentation, payer requirements, and aging accounts receivable, these changes add another layer of operational responsibility.
The question is simple: Is your business prepared to protect its revenue?
What’s Changing on October 28?
CMS has selected eight additional HCPCS codes for required prior authorization, with implementation beginning October 28, 2026.
Six codes will require prior authorization nationwide beginning October 28:
| HCPCS Code | Equipment Category |
| L0456, L0457, L0486 | Thoracic-lumbar-sacral orthoses |
| L1833 | Knee orthosis |
| E0194 | Air-fluidized bed |
| K0005 | Ultralightweight wheelchair |
Two additional upper-limb orthosis codes, L3761 and L3916, will follow a phased implementation schedule:
- October 28, 2026: California, Florida, Michigan, and New York
- January 26, 2027: Expansion to Arizona, Georgia, Illinois, Massachusetts, Ohio, Oregon, Pennsylvania, and Texas
- April 26, 2027: Nationwide implementation
These changes mean suppliers must carefully evaluate which products require authorization based on the HCPCS code, applicable implementation date, and state.
Importantly, not every item on CMS’s broader DMEPOS Master List requires prior authorization. Suppliers should distinguish between the Master List and the Required Prior Authorization List.
Why Should DME Suppliers Be Concerned?
Because delivering equipment does not automatically mean Medicare will pay for it.
For items subject to required prior authorization, suppliers must obtain the appropriate authorization determination and comply with applicable billing requirements.
Failure to follow the process can result in claim denials—even when the patient has a legitimate medical need for the equipment.
And for DME businesses, those denials can quickly become expensive.
Consider a supplier that routinely delivers wheelchairs, orthotic devices, or pressure-reducing support surfaces.
If authorization requirements are overlooked, the organization could experience:
- Increased claim denials and rework
- Delayed Medicare reimbursement
- Higher administrative expenses
- Growing accounts receivable balances
- Potential interruptions in equipment delivery
- Reduced cash flow needed to support inventory and operations
The financial impact is not limited to one denied claim. It can affect the efficiency and profitability of your entire operation.
Another Important Change: New DME Suppliers Face Additional Scrutiny
The October 28 expansion is not the only Medicare development suppliers should be watching.
Effective October 15, 2026, CMS implemented a nationwide probationary prior authorization process for certain newly enrolled DMEPOS suppliers and suppliers undergoing applicable changes of ownership.
This process applies to specified equipment codes and introduces a one-year probationary period beginning with the supplier’s first claim.
For DME businesses considering expansion, new locations, acquisitions, or ownership changes, understanding these requirements is especially important.
Growth should create new revenue opportunities—not unexpected reimbursement barriers.
Five Steps Every DME Supplier Should Take Right Now
1. Identify affected HCPCS codes
Review your current product inventory and claims history to determine whether you bill any of the newly selected codes.
Pay particular attention to the phased implementation requirements for upper-limb orthoses.
2. Review your authorization workflow
Determine whether your team has a reliable process for identifying authorization requirements before equipment is delivered.
Authorization responsibilities should be clearly assigned, tracked, and documented.
3. Audit medical necessity documentation
Review physician orders, supporting clinical records, and applicable Medicare coverage criteria.
Obtaining authorization does not eliminate the need to satisfy all other Medicare coverage, documentation, and billing requirements.
4. Prepare your billing and operations teams
Make sure staff responsible for intake, order processing, authorization, equipment delivery, and billing understand the changes.
A breakdown at any point in the process can affect reimbursement.
5. Monitor denials and reimbursement trends
Track authorization-related denials, claim processing delays, and outstanding receivables.
Identifying issues early can help prevent a manageable workflow problem from becoming a significant financial burden.
The Bigger Picture: Prior Authorization Is a Revenue Cycle Issue
Many DME organizations treat prior authorization as an administrative task.
In reality, it is an essential component of revenue cycle management.
When authorization, documentation, delivery, and billing processes operate independently, errors become more likely.
A proactive revenue cycle strategy connects these functions to help ensure that claims are accurate, properly supported, and submitted according to payer requirements.
The goal is not simply to submit more claims. It is to create a process that supports timely, accurate reimbursement while reducing avoidable administrative work.

Suppliers that prepare now can position themselves to minimize disruption, improve operational consistency, and protect their revenue.
