The 2025 ICD-10-CM updates introduce greater specificity for neurological disorders, enabling better tracking of conditions and improved reimbursement. Key changes include:

• Epilepsy and Seizure Disorders: New codes under G40 provide detailed classifications for seizure types, such as:
  • G40.A01: Childhood absence epilepsy, intractable
  • G40.B11: Juvenile myoclonic epilepsy, intractable with status epilepticus These codes require physicians to document seizure type, frequency, and intractability to ensure accurate code selection.
• Stroke and Cerebrovascular Diseases: New codes track stroke severity and rehabilitation stages, such as:
  • Codes under I63 for cerebral infarction with specific modifiers for functional outcomes. This supports better data collection for stroke recovery and treatment planning.
• Parkinson’s Disease: Expanded codes under G20–G26 differentiate between idiopathic Parkinson’s, secondary parkinsonism, and parkinsonism due to other diseases. For example:
  • G20.A1: Idiopathic Parkinson’s disease, early stage This allows for better tracking of disease progression and treatment outcomes.
• Functional Neurological Disorders: New codes under F44–F49 address functional motor and sensory disorders, reflecting growing recognition of these conditions in clinical practice.
• Rare Neurological Diseases: Codes for rare conditions like Huntington’s disease and amyotrophic lateral sclerosis (ALS) have been added to improve documentation for research and reimbursement.

Actionable Tip: Neurologists should ensure documentation includes specific details like laterality, severity, and treatment response to align with these updated codes. Regular training on ICD-10-CM updates is essential for coding staff.

 CPT Code Updates for Neurological Procedures

The AMA has introduced and revised CPT codes to reflect advancements in neurological diagnostics and treatments. Key updates for 2025 include:

• Electroencephalography (EEG):
  • 95700–95726: These codes replace older EEG codes (e.g., 95827) and differentiate based on monitoring duration, presence of video, and whether the provider is present or reviewing remotely. For example:
    • 95700: EEG data analysis and interpretation in ambulatory settings
    • 95717–95720: Long-term EEG monitoring with video Accurate documentation of monitoring duration and components is critical.
• Electromyography (EMG) and Nerve Conduction Studies (NCS):
  • 95860–95864: Updated EMG codes for different muscle groups.
  • 95907–95913: Revised NCS codes for single and multiple nerve studies. These updates improve specificity for diagnosing neuropathies and muscle disorders.
• Deep Brain Stimulation (DBS):
  • New CPT codes for DBS programming and management reflect the growing use of this procedure for Parkinson’s disease and essential tremor. For example:
    • 95983: Initial DBS programming, first hour
    • 95984: Subsequent DBS programming, each additional 15 minutes Time-based coding is essential for these procedures.
• Neurostimulation and Neuromodulation:
  • New codes for spinal cord stimulation and other neuromodulation therapies support billing for chronic pain and movement disorder treatments.

Actionable Tip: Use a coding checklist to ensure all components of EEG, EMG, and DBS procedures are documented, including time spent and whether services are technical or professional.

 Telehealth and Remote Monitoring Reimbursement

The expansion of telehealth in neurology, accelerated by the COVID-19 pandemic, has led to permanent changes in reimbursement policies. Key updates for 2025 include:

  • Codes like 99453 (initial setup for remote physiologic monitoring) and 99454 (device supply with daily recording) support remote monitoring for conditions like epilepsy and migraines.
  • 98975–98978: Remote therapeutic monitoring codes for cognitive behavioral therapy and other interventions.
• Place of Service (POS) Codes:
  • Use POS 02 for telehealth services delivered to patients at home and POS 10 for telehealth to patients in other locations. Modifier 95 indicates synchronous telemedicine services.
• Medicare and Private Payer Policies:
  • Medicare and commercial insurers have updated reimbursement rates for telehealth consultations and neuropsychological testing, particularly for dementia and Alzheimer’s evaluations.

Actionable Tip: Ensure documentation for telehealth visits includes medical necessity, time spent, and patient consent to avoid claim denials.

 Evaluation and Management (E/M) Coding Refinements

E/M coding guidelines continue to evolve, with a focus on medical decision-making (MDM) and time-based coding. Key changes for neurologists include:

• MDM as Primary Factor: The complexity of MDM determines the E/M level (e.g., 99213 vs. 99215). Neurologists managing chronic conditions like multiple sclerosis or epilepsy must document the complexity of decision-making thoroughly.
• Time-Based Coding: Total time spent on patient care, including non-face-to-face activities like chart review, can be used to select E/M levels. For example:
  • 99214: 30–39 minutes of total time
  • 99215: 40–54 minutes of total time
• Elimination of History and Exam Requirements: History and physical exam are no longer key components for E/M code selection, simplifying documentation for neurologists.

Actionable Tip: Use EHR templates to capture MDM complexity and time spent, ensuring compliance with updated E/M guidelines.
