Learn about CPT Code 62350 for intrathecal or epidural catheter implantation, its billing rules, and documentation needs.

Use Code

What is intrathecal or epidural catheter implantation?

The 62350 CPT code refers to the implantation, revision, or repositioning of a tunneled intrathecal or epidural catheter, primarily used for delivering medication directly into the cerebrospinal fluid or epidural space surrounding the spinal cord. This procedure is often part of a pain management strategy for patients experiencing chronic pain, intractable pain, or severe spasticity, especially when systemic opioids or less invasive medical therapy are no longer effective.

This type of catheter implantation procedure is typically used in conjunction with an implantable infusion pump, pain pump, or external pump, enabling long-term medication administration, such as intrathecal morphine delivered for cancer-related pain or spasticity from conditions like multiple sclerosis or spinal cord injury.

The catheter is carefully placed in the lumbar region or another segment of the spine and spinal cord, where it delivers drugs directly to the target area for pain relief. Patients may undergo a preliminary trial before permanent implantation to assess the therapy’s effectiveness. Once deemed successful, the device, whether a programmable pump, external pump, or implantable pump, can be inserted for term medication administration via an external pump or implantable reservoir.

Because of its complexity, this procedure on the spine must be performed by a skilled physician and supported by thorough documentation, including references to applicable procedure codes, medicaid services, and medicare policy standards. The 62350 CPT code encompasses all aspects of implantation, revision, or replacement of the catheter, making it vital for billing and coding accuracy.

Documentation requirements

Comprehensive operative documentation should include:

Clinical indication, such as chronic pain, severe spasticity, or intractable pain, and prior response (or lack thereof) to less invasive medical therapy or systemic opioids
Patient consent for catheter implantation and anesthesia administration
Precise anatomical site of catheter implantation (e.g., L3–L4 intrathecal entry into the spinal cord or epidural space)
Pump details, including manufacturer, model, and the subcutaneous or external pump placement site
Intraoperative confirmation of proper catheter positioning via imaging (e.g., fluoroscopy)
Programming parameters for the implantable infusion pump, such as flow rate, drug concentration, and delivery schedule

Additional documentation should also note:

Device testing and system functionality
Surgical closure technique
The patient’s immediate postoperative condition and plan for follow-up or long-term medication administration

These elements help support medical necessity and ensure compliance with Medicare, Medicaid services, and commercial payer requirements for invasive medical therapy and procedures on the spine.

Billing guidelines

CPT 62350 is a global surgical procedure code encompassing both the implantation and initial catheter insertion. It should not be reported with catheter placement codes, such as 62360–62362, since these codes are for pump placement procedures, which are performed at the same session.

General anesthesia is often used, and related anesthesia services may be billed separately. The code includes image guidance; do not report fluoroscopy separately.

Medicare and commercial payers may require prior authorization and documentation of failed trials with systemic agents. Implantation following a successful intrathecal drug trial (e.g., with a temporary catheter) is a common pathway.

Other relevant CPT codes

62351 – Revision or removal of spinal infusion pump/reservoir
62355 – Removal of previously implanted intrathecal or epidural catheter
95991 – Refilling and maintenance by physician or QHP

Frequently asked questions

Yes. Fluoroscopy or other image guidance used during the placement of the epidural catheter for long-term medication delivery is bundled into the 62350 CPT code and should not be billed separately.

No. The catheter implantation is a component of 62350. If performed during the same surgical session, it should not be reported with other catheter placement codes. This applies to both tunneled intrathecal and epidural catheter placements used with implanted infusion pumps.

Often yes. Many payers require prior authorization, particularly when using implantable infusion pumps for combination therapies involving opioid and non-opioid drugs. Documentation must show failed conservative treatments, results of a preliminary drug trial, and that the system is functioning as intended for medication delivery.
