The Next Step for Your CGM Business

How to establish a scalable resupply model for diabetes care

By Brian O’Neill

Continuous glucose monitoring (CGM) is revolutionizing diabetes care—and it’s also changing how durable medical equipment (DME) providers structure their businesses. While launching a CGM program is an important first step, long-term success lies in establishing a scalable, patient-centered resupply model. That’s where real revenue, efficiency and impact are found.

For DME providers, resupply isn’t just about shipping another sensor. It’s about building systems that keep patients compliant, engaged and consistently receiving the tools they need to manage their health.

The Importance of Resupply in CGM

CGM products are inherently built around replacement. Sensors typically require replacement every 10 to 14 days. Transmitters may last three months. Receivers or readers—if the patient is not using a smartphone—can last even longer. This predictability offers DME providers a valuable opportunity to create a recurring revenue stream.

But to do this well, the resupply process needs to be efficient, automated and compliant with payer requirements.

Build Around Predictable Reorder Cycles

The foundation of any resupply program is a system that tracks when patients are due for new sensors, transmitters or readers. Whether through a customer relationship management system, an electronic health record (EHR) integration or a billing platform like Brightree or NobleHouse, your system should:

Set patient-specific resupply timelines
Trigger alerts for upcoming reorders
Support automated communication via email, text or phone

This ensures patients are prompted before they run out—and keeps your inventory flow in sync.

Patient Communication Is Everything

One of the most common pitfalls in CGM resupply is losing the patient due to a lack of communication. People may move, switch devices, forget to reorder or run into insurance issues. Consistent communication ensures your patients know what to expect—and when.

Top providers use multi-channel outreach and give patients the ability to confirm, update or cancel their resupply. When resupply becomes predictable and seamless, patients stay loyal. It’s not just fulfillment—it’s continuity of care.

A scalable CGM resupply program is more than logistics—it’s a strategic advantage. It improves patient outcomes, creates predictable revenue & builds long-term loyalty between you and the people you serve.

Documentation Still Matters

Just because a patient is already using a CGM doesn’t mean documentation requirements go away. Many insurers require updated documentation for renewals or even certain supply shipments.

Make sure your resupply system ties into your documentation tracking process, flagging any missing or outdated paperwork. Working with a supply partner that understands these requirements can reduce errors and denials.

Avoiding Supply Gaps With Strategic Inventory

Resupply is only scalable if you have consistent access to product. If your warehouse or vendor is out of stock, the chain breaks.

That’s why many providers rely on wholesalers who:

Maintain dependable stock of major CGM brands
Offer real-time inventory updates
Provide fast, trackable shipping to minimize delays

A wholesaler with proactive communication ensures you can forecast accurately and avoid patient care disruptions due to product shortages.

Final Thoughts

A scalable CGM resupply program is more than logistics—it’s a strategic advantage. It improves patient outcomes, creates predictable revenue and builds long-term loyalty between you and the people you serve.

By combining smart automation, patient-centered communication and reliable inventory partners, DME providers can transform resupply from a task into a growth engine.
