Interactive Product: The Basics of NCS and EMG Coding-Larger text slides- not full content

Pdf Summary

This document is an interactive guide to electrodiagnostic billing, specifically focusing on coding for electromyography (EMG) and nerve conduction studies (NCS). <br /><br />For EMG studies performed with a NCS on the same day, the appropriate codes to use for billing are 95885, 95886, or 95887. These codes are considered "add-on" codes and are billed in units based on the number of extremities tested. A complete study of a limb should include at least 5 muscles innervated by 3 or more peripheral nerves or 4 or more spinal levels. Non-extremity codes can also be billed for muscles innervated by cranial nerves, the phrenic nerve, paraspinal muscles, abdominal muscles, or other muscles not associated with an extremity.<br /><br />When there is no NCS performed on the same day, different CPT codes should be used for billing, such as 95860-95864 for complete studies, 95870 for limited studies, and others for specific areas like the larynx, hemidiaphragm, or muscles supplied by cranial nerves.<br /><br />For NCS, the appropriate codes to use depend on the number of nerves tested. Codes 95907-95913 are the main codes used to bill for NCS, with each code representing a specific number of nerves tested. However, it should be noted that most nerves have a contralateral counterpart, so bilateral testing may be necessary for comparison purposes.<br /><br />Appendix J provides a comprehensive list of sensory, motor, and mixed nerves that can be counted when billing for NCS. Each nerve qualifies as one unit of service, and multiple NCS codes cannot be billed for a single patient on the same day.<br /><br />Overall, this guide aims to help physicians accurately code and bill for electrodiagnostic procedures, ensuring appropriate reimbursement while adhering to established guidelines and norms.
