: Consensus statements regarding the evidence-base for lumbar total disc replacement, as it pertains to payer decision-making, were developed through a modified-Delphi technique involving 17 spine surgeons and a former payer medical director. The Delphi process involved one round of anonymous survey and one round with a face-to-face meeting. The survey was a 51-item, electronically administered questionnaire to determine level of agreement with proposed statements on the evidence for lumbar total disc replacement and to provide additional diagnosis and management practice information for further deliberations. ⋯ The voting processes during meeting deliberations remained anonymous. Consensus was defined as ≥ 90% agreement. Consensus was reached on 11 statements, divided into themes that focused on patient eligibility and diagnosis, evidence criteria for coverage decisions, clinical evidence, and budgetary implications.
