Chapter 23 Coding and Billing for Neurostimulation

Jeffrey T.B. Peterson

Chapter Overview

Chapter Synopsis: Most physicians want to spend their time treating patients, not dealing with payment issues, but the reality is that coding and billing are an integral part of any medical practice. Electrical stimulation for indications of intractable pain is a widely used and accepted technique with demonstrable benefits to many patients. Proper handling of the documentation associated with payment can protect not only the patient and the clinic but the very practice of electrical stimulation itself. Inappropriate coding or billing can expose the practice to legal liability. This chapter provides some guidance in the proper handling of the process; but, because of regional differences and continual updates to policies, clinicians should regularly refer to relevant guidelines. Medical necessity for the technique needs to be documented, including the patient’s disease state, pain characteristics, and failure of other treatments. Providing the most complete documentation of these conditions before treatment increases the likelihood of payment; failure to do so represents the most common cause of nonpayment. The location of the procedure can also affect payment, as can billing by a facility versus by a physician.

Important Points:

Inappropriate coding and billing practices may expose the practice to financial and legal liability.

Medical necessity must be properly documented in the note or operative preamble.

Always refer to national coverage determination (NCD) and local coverage determination (LCD) guidelines for issues specific to the service and practice locale.

Ensure that billing and documentation are appropriate for the site of service setting.

Proper authorization is a key component of coding and billing protocol.

Non-adherence to carrier requirements could lead to denial of authorization.

Improper documentation may lead to payer audit and payer sanctions.

Inadequately trained billing personnel can be a compliance and financial risk to the practice.

Improper modifier usage can result in payer audit.

Introduction

Appropriate documentation and coding for neurostimulation procedures are not only imperative for maintaining a proper record, but, if they are done incorrectly, they can expose the practice to financial and legal liability risk.¹ Because of regionally diverse payer- and carrier-related issues, this chapter presents an overview of coding and billing topics. It is also important to note that regulations pertaining to coding and billing changes are updated routinely; all readers are strongly encouraged to refer to their local carrier policies for the latest information. Although local policies are prone to change, proper documentation as a measure of practice health and stability remains a staple of practice management that demands daily attention.

Proper Documentation and Medical Necessity

Medical necessity should be documented in the office notes or operative preamble. This documentation should include the disease state, pain characteristics, functional limitations, and degree of suffering. Additional documentation should include failed treatments such as physical therapy, medications, injections, and previous surgical efforts. Any current options should be addressed, and a decision to move forward with the device should be noted. The surgical documentation should not only represent justification for necessity, but should contain complete, concise data that support what the practitioner billed and why. An example of this documentation would be, “Before this spinal cord trial the patient underwent medical management with oral medications from different classes (list classes), injections (list injections), physical medicine, and other (list other options). The patient had no acceptable surgical options and wished to move forward. Informed consent was obtained, and the patient was taken to the procedure area.”

Spinal Cord Stimulation

The proper current procedural technology (CPT) coding for the trial and permanent stimulator procedures is listed in Table 23-1.² All patients must meet clinical criteria, and medical necessity should be documented extensively in the patient record. Note that billing for removal of the trial percutaneous leads is not appropriate if no surgical incision and no surgical anchoring were performed in the initial placement. These codes were created specifically for trial leads that were placed using the “cut-down” technique. The global period for the listed surgical codes is 10 days. Wound checks and physical examinations are not typically billable for the first 10 days after placement of the spinal cord stimulation (SCS) system.
