Advanced Diabetes Supply in Carlsbad's La Costa area has specialized in nationwide home delivery of continuous glucose monitors, insulin pumps, and diabetes testing supplies from its Campbell Place headquarters since 2002. The distribution model handles Medicare, Medicaid, and commercial insurance billing on behalf of patients, eliminating the paperwork burden that home-health coordinators at BrightStar Care also navigate when arranging durable medical equipment for homebound diabetic clients in North County. Cardinal Health acquired Advanced Diabetes Supply in November 2024, integrating the Carlsbad operation into its national medical distribution network while maintaining local fulfillment from the 92009 ZIP code. The product catalog covers CGM systems from major manufacturers, insulin pump supplies, lancets, glucose meters, control solutions, and diabetic footwear certified under Medicare's Therapeutic Shoe Program. CGM data streams generated by devices in the Advanced Diabetes Supply catalog integrate with remote patient-monitoring platforms, a telehealth workflow that Welby Health in Carlsbad uses to track glucose trends between in-person clinical visits. The fulfillment operation processes Dexcom G7 and FreeStyle Libre 3 sensor shipments under Medicare's Durable Medical Equipment category E0787, requiring 90-day prescription renewal cycles and prior-authorization documentation for each CGM resupply order.
