## **What is HCPCS C1767?**
HCPCS C1767, an HCPCS Level II C-code (Device Category Code), has a service type of Outpatient Prospective Payment System (OPPS) for Assorted Devices, Implants, and Systems. Healthcare providers use this code to report the cost of the device (the pulse generator) implanted during a surgical procedure, such as a Spinal Cord Stimulator (SCS) implantation, as C-codes are generally used for temporary or transitional billing for new medical devices in the hospital outpatient setting.
The equipment described under this code refers to an implantable, non-rechargeable neurostimulator generator—essentially the battery-powered “pulse generator” component used in neurostimulation systems such as spinal cord, peripheral nerve, or sacral nerve stimulators.
This device generates electrical pulses delivered via leads to modulate specific neural targets, offering therapeutic relief for chronic pain, spasticity, or urinary dysfunction when conventional therapy or other therapeutic interventions have failed to achieve sustained improvement. In clinical practice, patients are closely monitored after implantation to assess functional outcomes, manage potential severe adverse events, and document treatment response over follow-up visits.
The “non-rechargeable” designation indicates that once the internal battery depletes—typically after several years—the generator requires surgical replacement.
## **HCPCS code C1767 documentation requirements**
Accurate and detailed documentation is critical for establishing medical necessity and supporting reimbursement. While specific requirements can vary by payer (e.g., Medicare Local Coverage Determinations or LCDs), general documentation for a neurostimulator procedure should include information that demonstrates how the therapy helps treat patients with intractable conditions and achieves meaningful clinical outcomes over time.
- **Medical necessity**: Clear documentation of the patient's condition (e.g., chronic pain, failed back surgery syndrome, complex regional pain syndrome) and that they meet the criteria for the implant (e.g., conservative therapies like pain medications, physical therapy, or nerve blocks have failed).
- **Procedure report**: Operative note detailing the surgical procedure, including the implantation of the neurostimulator generator and the electrodes/leads.
- **Device information**: The name and type of the device (confirming it is a non-rechargeable generator), the invoice for the device, and the U.S. Food and Drug Administration (FDA) approval status.
- **Trial period results (if applicable)**: For spinal cord stimulation, documentation of a successful temporary trial/test stimulation phase often precedes permanent implantation.
- **Pre-procedure assessments**: May include imaging results (e.g., MRI or CT scans) and, for certain procedures, a psychological evaluation to ensure patient suitability for the implant.
## **C1767 billing requirements**
Outpatient claims require correct pairing of the C-code with suitable revenue center coding to ensure accurate cost capture. Non-facility provider claims (e.g., physicians billing under Part B office services) typically do not bill the device separately, as it is incorporated into global or bundle reimbursements.
- **Hospital Outpatient Setting (OPPS)**: C-codes, including C1767, are primarily used by hospitals or ambulatory surgical centers to bill the cost of the implantable device under Medicare's OPPS.
- **Device vs. procedure**: C1767 is for the device (product cost), not the surgical procedure to implant it. The procedure is billed using a separate CPT code (e.g., CPT code 63685 for permanent implantation of a spinal neurostimulator pulse generator).
- **Medicare claim edits**: Medicare often employs claims processing edits that require the device code (C1767) to be included on claims that contain the associated procedure code (CPT) that is assigned to a device-dependent Ambulatory Payment Classification (APC).
- **Revenue codes**: In a hospital outpatient setting, C1767 may be reported under specific revenue codes, such as 272, 274, 275, 276, 278, 279, 280, 289, 290, or 624, depending on where the procedure was performed.
- **Prior authorization**: Prior authorization may be required by payers for both the trial and the permanent implantation of the device.
