60% of returned claims are never resubmitted and not only that, but they also remain unpaid because of this as per an AHIMA study. What does this have to do with neurology? Well, neurology is one of those specialties that has more chances of getting its claim rejected because of the complexities of neurology medical billing.
In neurology medical billing, the procedures are more complex than most, payers are constantly changing policies, and with recent updates there’s much more to look at in order to stay compliant and get paid. The only way to get through these challenges is to be knowledgeable, which this guide is about, to give you everything there is to know.
For starters, CMS released the Physician Fee Schedule for October 31, 2025 and is impacting neurology medical billing directly with a few notable changes. Some of these changes are easy to sink in but on the other hand, some require thorough consideration. And if you don’t take any action, even missing one of these changes can cause claim denials or already be causing issues without you noticing.
When it comes to coding, you just need to keep in mind two code types: ICD-10 and the CPT codes. One supports the other and needs to be aligned with neurology medical billing best practices.
The range of neurology CPT codes runs from 95700 to 96020. Here are some of the commonly billed procedure categories within neurology medical billing:
| CPT Code | Procedure | Key Detail |
|---|---|---|
| 95812 | Routine EEG | Under 24 hours, awake/drowsy/asleep/coma |
| 95813 | Routine EEG | Over 41 minutes |
| 95816 | Routine EEG | 20 to 40 minutes, awake and drowsy |
| 95819 | Routine EEG | Awake and asleep |
| 95860-95864 | EMG | Varies by number of extremities studied |
| 95905-95913 | Nerve Conduction Studies | Varies by number of studies performed |
| 95970, 95983, 95984 | Neurostimulator Programming | Time-based, face-to-face over 8 minutes triggers one unit |
| 99441-99443 | Telehealth Consultations | Requires POS 02 or 10 and Modifier 95 |

The selection is determined by the duration and condition of the patient. Choose the wrong code and you will be facing compliance risk.
The following are the frequently used neurology ICD-10 codes in neurology and their application:
| ICD-10 Code | Condition |
|---|---|
| G20 | Parkinson's disease |
| G40 | Epilepsy |
| G43 | Migraine |
| G35 series | Multiple sclerosis (see critical update below) |
Modifiers are where neurology billing tends to have errors which result in revenue loss. This is mainly caused by the misuse, omission, or both. Here are the modifiers that matter most for neurology medical billing:
Compliance is built into every step of the neurology medical billing process. Because even if you code correctly but the documentation isn’t proper, it is a compliance issue. The following are the core elements that will keep your neurology practice.
Documentation is what every claim either stands or falls on. There’s much more as the clinical record needs to support not just the procedure with the medical necessity behind it. This means that the diagnosis, findings, patient history, and clinical reasoning are included.
Not just that, in a 2024 claim report from AMA, 52% of neurology claim denials were from documentation or medical necessity. This alone is enough to focus on the following key documentation requirements:
The second on the neurology medical billing compliance checklist is the prior authorization. It’s not optional and is required for the procedures and missing any of it will cause denials that won’t be appealed afterwards. The following are the most commonly requiring prior authorization:
| Procedure | Authorization Risk Level |
|---|---|
| Certain prolonged EEG monitoring | Moderate |
| EMG studies | Moderate to High |
| Advanced imaging (MRI, CT) | High |
| Nerve conduction studies | High |
| Botulinum toxin injections for migraines | High |
| Neurostimulation implants and programming | High |
As a provider, you already know that missing a filing deadline is an automatic denial with no recovery at all and it goes with every payer. Here are some of the timely filing windows varying by payer to stay compliant:
Keep in mind that payer specific policies in neurology change often enough that one policy in effect six months ago may no longer apply. Also, Coverage criteria for nerve conduction studies, EEGs, and EMGs are regularly updated by Medicare and commercial payers. So be vigilant.
From assessments to conditions, there is too much sensitive data that practices need to handle and if they fail to do so, HIPAA compliance is gone. That’s why you need to carry additional privacy considerations in order to stay HIPAA compliant:
Now that you know everything there is to know about neurology medical billing, it’s time to get things the right way. The code changes are definitely worth considering, compliance requirements are strict, and there’s a cost to getting these wrong. It will lead you to denied claims and will be aging account recievabls that no practice is ready to chase.
The practices that will go through this properly will stay compliant and get reimbursed properly.
