Generate Your Free Appeal Letter →Your insurer refused to pay at the standard rate because your provider is outside your plan's network.
Most plans only pay full rates for in-network providers. Out-of-network claims are denied or reimbursed at a lower rate — sometimes nothing. This often catches patients off-guard when a specialist, anesthesiologist, or facility is unexpectedly out-of-network.
Check whether the No Surprises Act (US), balance billing protections, or continuity of care provisions apply. Emergency care and situations where in-network alternatives were unavailable give strong grounds for appeal.
