CPT code 62351 represents surgical implantation, replacement, or repositioning of a previously tunneled intrathecal or epidural catheter, including a laminectomy, to permit medication delivery into the cerebrospinal fluid via an external or internal reservoir pump. This code covers procedures used for severe acute or chronic pain (including cancer-related pain and postoperative pain) and for conditions such as spasticity that require targeted neuraxial drug delivery. Nationally, this code is relevant to hospitals, neurosurgery and pain management practices, and payers due to the procedural complexity, facility resources required, and implications for bundled payment and utilization oversight.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context about the intended use of the procedure, typical sites of service, and what this service line entails. The publication also provides benchmarks and policy context where available, including payer coverage patterns, common billing modifiers and coding considerations, and related procedural coding for neuraxial drug-delivery systems. Data gaps are identified when input was not provided. The material is intended for coding professionals, revenue cycle managers, and clinical leaders who require a concise technical overview of CPT code 62351 and its role in neuraxial drug delivery services.
