2026 Coding Guide
Pdf Summary
The AANEM 2026 Coding Guide serves as a comprehensive resource for neuromuscular and electrodiagnostic (EDX) coding, aiding physicians and healthcare professionals in accurate billing and documentation. The guide covers fundamental coding basics, detailed EDX and neuromuscular CPT codes, evaluation and management (E/M) coding principles, ICD-10-CM diagnostic coding, the Resource-Based Relative Value Scale (RBRVS), and practical suggestions with sample documents.

<strong>Section Highlights:</strong>

- <strong>Coding Basics:</strong> Explains CPT code categories (Category I for widely accepted procedures, II for performance tracking, III for emerging technologies), the concept of global periods affecting postoperative care billing, and essential coding principles.

- <strong>Electrodiagnostic and Neuromuscular Codes:</strong> Details supervision requirements (physician must perform or directly supervise needle EMG; physical therapists certified by ABPTS may perform certain procedures per state laws). Clarifies CPT code specifics for nerve conduction studies (NCS), needle electromyography (EMG), autonomic testing, chemodenervation (e.g., botulinum toxin injections), evoked potentials, intraoperative monitoring, and neuromuscular ultrasound. Appendix J lists nerves for accurate NCS coding. Emphasizes correct use of add-on codes and modifiers.

- <strong>Evaluation and Management (E/M):</strong> Defines E/M services, outlining criteria for new vs established patients, service settings, and levels of medical decision making (straightforward to high complexity). Highlights recent CMS policy updates including permanent virtual supervision, telehealth considerations, and removal of efficiency adjustments for time-based E/M codes. Supports billing both E/M and EDX services on the same day when properly documented with modifier 25.

- <strong>ICD-10-CM Diagnostic Codes:</strong> Explains usage, specificity, and guidelines for neurologic and neuromuscular diagnoses, including codes for neuropathies, motor neuron disease, myopathies, pain syndromes, injuries, and others pertinent to EDX services.

- <strong>Resource-Based Relative Value Scale (RBRVS):</strong> Describes Medicare reimbursement calculation components (work RVUs, practice expense, malpractice, geographic adjustments) with updated 2026 conversion factors, efficiency adjustments, and practice expense redistribution affecting payments.

- <strong>Modifiers:</strong> Clarifies use of key modifiers such as 22 (increased services), 25 (separate E/M on same day), 26 (professional component), 50 (bilateral), 59 (distinct procedural service), and others including HCPCS Level II X-series for various billing scenarios.

- <strong>Practical Tools and Advocacy:</strong> Provides sample billing forms, appeal letters for denials (e.g., simultaneous E/M and EDX, incorrect nerve counts), and letters to state boards regarding quality concerns. Encourages physician engagement in reimbursement education and quality assurance.

- <strong>Frequently Asked Questions:</strong> Addresses common coding challenges, billing guidance for EDX procedures, use of Appendix J, proper codes for repetitive stimulation, intraoperative monitoring, autonomic testing, neuromuscular ultrasound, and billing compliance.

Overall, the guide assists providers in navigating complex neuromuscular and electrodiagnostic coding scenarios, ensuring appropriate reimbursement and compliance with payer and CMS requirements for 2026.
