Analysis of cost differences between comparing percutaneous transforaminal endoscopic discectomy (PTED) and unilateral biportal endoscopy (UBE) in the treatment of lumbar disc herniation under diagnosis-related group (DRG) payment: a retrospective co

PTED provides a more cost-effective option than UBE for LDH treatment under DRG payment, without compromising clinical outcomes. The economic benefit of PTED is consistent across various patient subgroups, supporting its use especially in resource-sensitive settings. These findings offer valuable insights for clinicians and policymakers aiming to optimize resource allocation and reduce financial burden within DRG frameworks.
