OK SB1047

Prohibits out-of-network providers and facilities from "surprise billing" patients for emergency care or non-emergency services rendered at in-network facilities, limiting patient costs to what they would pay for in-network care

Requires health insurance carriers to reimburse out-of-network providers at the "minimum benefit standard" (80th percentile of allowed amounts from an independent benchmarking database) within 30 days for electronic claims or 45 days for paper claims

Establishes a verification process through the Insurance Commissioner allowing out-of-network providers to challenge reimbursement amounts within 30 days of payment, with response required within 15 days

Imposes penalties on carriers that underpay: the difference between the minimum benefit standard and billed amount, split 50% to the provider and 50% to the Oklahoma Health Insurance High Risk Pool, with additional fines possible for patterns of underpayment
