Insurance Claim Denied in Chattanooga, TN? Here's How to Fight Back

Chattanooga sits at the Tennessee-Georgia border, straddling a state line that creates real health insurance complications. Many Chattanooga area residents live in Catoosa, Walker, or Dade County, Georgia, while working and receiving healthcare in Tennessee. Others live in Tennessee but cross into Georgia for specific providers. When a claim arises from care delivered near this border, the applicable insurance law — Tennessee's or Georgia's — depends on where the plan is issued, not necessarily where the care was received.

Chattanooga's Health System and Insurance Landscape

Erlanger Health System is Chattanooga's public hospital and Level I Trauma Center, operated by the Hospital Authority of Hamilton County. Erlanger is affiliated with the University of Tennessee College of Medicine Chattanooga and serves as the region's academic and safety-net medical center. CHI Memorial Hospital (CommonSpirit Health) is the major Catholic health system in the Chattanooga market. Parkridge Medical Center (HCA Healthcare) rounds out the inpatient options.

Commercial insurance in Hamilton County is led by BlueCross BlueShield of Tennessee (BCBST), which dominates the state's commercial market. UnitedHealthcare and Aetna serve large employer groups, including automotive manufacturers and logistics companies. Tennessee's TennCare Medicaid in the Chattanooga region is served by UAHP (UnitedHealthcare Community Plan) and BlueCare Tennessee.

For Georgia-side residents, the applicable insurer may be a Georgia-regulated plan — which falls under the Georgia Department of Insurance (GDI) rather than TDCI.

The Tennessee-Georgia Border Healthcare Puzzle

Patients from north Georgia counties who seek healthcare in Chattanooga represent a significant share of Hamilton County hospital volume. Key complications:

• Georgia-regulated plans at Tennessee hospitals: A Walker County, Georgia resident with a Georgia-issued health plan seeking care at Erlanger is covered under Georgia insurance law. If that claim is denied, the appeal goes through Georgia's process — not Tennessee's.
• TennCare vs. Georgia Medicaid: Tennessee TennCare will not pay for routine care received in Georgia without Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization; Georgia Medicaid similarly does not cover Tennessee-based providers without specific authorization.
• Out-of-state emergency care: Emergency care received across the state line is generally covered under federal law (EMTALA protections and the No Surprises Act), but follow-up care for an emergency may not be covered as readily.

Common Denial Patterns in Chattanooga

• Erlanger billing complexity: As a public academic medical center, Erlanger bills under both facility and physician practice entities. Prior authorization obtained for the facility procedure may not cover physician services billed separately.
• Automotive industry ERISA plans: Chattanooga's Volkswagen and Amazon facilities, along with other large manufacturers, offer self-funded ERISA plans. These are not governed by Tennessee state law — ERISA applies.
• CHI Memorial network negotiations: CHI Memorial's CommonSpirit ownership has led to evolving network contracts with BCBST and other carriers. Patients should confirm network status before scheduling elective procedures.
• TennCare specialty referral denials: Hamilton County TennCare enrollees seeking subspecialty care at Erlanger or CHI Memorial may face prior authorization denials from their MCO.
