Did your mom ever tell you or did you ever tell your own children, “Because I said so!”? That may or may not have worked to accomplish the desired behavior depending on the pre-existing dynamics of the parent-child relationship. CMS encounters the same problem when dealing with the provider community. Sometimes providers follow the rules, sometimes they have never heard of the rules, sometimes they ignore the rules and sometimes they deliberately disobey. This is why where there are Medicare coverage policies, Medicare medical review audits will likely follow. Such is the case for Spinal Cord Stimulators.

Medicare has a National Coverage Determination (NCD) for Electrical Nerve Stimulators (NCD 160.7) which addresses Spinal Cord (Dorsal Cord) Stimulation. The following conditions must be met in order for Medicare to make payment for these services:

• The implantation of the stimulator is used only as a late resort (if not a last resort) for patients with chronic intractable pain;
• Other treatment modalities (pharmacological, surgical, physical, or psychological therapies) have been tried and did not prove satisfactory, or are judged to be unsuitable or contraindicated for the given patient;
• Patients have undergone careful screening, evaluation and diagnosis by a multidisciplinary team prior to implantation. (Such screening must include psychological, as well as physical evaluation);
• All the facilities, equipment, and professional and support personnel required for the proper diagnosis, treatment training, and follow up of the patient must be available; and
• Demonstration of pain relief with a temporarily implanted electrode precedes permanent implantation.

In addition to the NCD, several Medicare Administrative Contractors (MACs) also have Local Coverage Determinations that address this procedure.

As stated above, a medical review audit often follows coverage policies. The Medicare Supplemental Medical Review Contractor (SMRC) recently published their findings for Project Y3P167 – Spinal Cord Stimulator (SCS) Services. The review looked at claims that contained CPT codes 63650 (Percutaneous implantation of neurostimulator electrode array), 63655 (Laminectomy for implantation of neurostimulator electrode plate/paddle), and 63685 (Insertion or replacement of spinal neurostimulator pulse generator or receiver). There was a 72% denial rate for this review, with 26% of claims denied for lack of record submission and 46% denied for failing to meet Medicare’s coverage requirements. According to the report, “The main reason for claim denials following medical review was the provider’s failure to provide documentation of a psychiatric evaluation/screening as required by NCD 160.7.”

Hospitals that provide this service should evaluate their practices and documentation to make sure Medicare’s requirements for payment are being met. Why? Because Medicare said so!
