Epilepsy monitoring not indicated (Updated for 2026)

Common Causes for NEURO05

Denials with code NEURO05 typically happen for the following specific reasons:

• The clinical documentation failed to show a history of refractory or drug-resistant epilepsy, such as the failure of two or more anti-seizure medications.
• The patient's spells or seizure semiology were not sufficiently documented to justify the transition from a routine EEG to continuous long-term monitoring.
• The admission did not meet Milliman Care Guidelines (MCG) or InterQual criteria for inpatient-level video-EEG monitoring, suggesting the service could have been performed in an outpatient setting.
• Lack of documentation demonstrating that shorter, routine, or ambulatory EEGs were inconclusive or clinically inappropriate for the clinical question at hand.

How to Prevent NEURO05 Denials

To avoid receiving this denial in the future, implement these specific checks:

• Establish a robust prior-authorization process that aligns patient clinical records with specific payer Local Coverage Determinations (LCDs) for long-term EEG monitoring.
• Ensure physician documentation explicitly details the failure of specific anti-seizure medications, the frequency of intractable spells, and the diagnostic limitations of previous routine EEGs.
• Implement clinical screening checklists based on MCG or InterQual criteria prior to scheduling or admitting patients for video-EEG monitoring units.
• Clearly document the specific, complex diagnostic question being addressed, such as differentiating epileptic from non-epileptic psychogenic seizures or localized seizure focus mapping.

Denial Code: NEURO05 - Epilepsy monitoring not indicated

Dear Appeals Department,

I am writing to appeal the denial of the above-referenced claim, which was denied with code NEURO05: "Epilepsy monitoring not indicated".

We are appealing the denial for the long-term video-EEG monitoring services, which were medically indicated and necessary for the management of this patient's condition. In accordance with the American Clinical Neurophysiology Society (ACNS) guidelines and CMS Local Coverage Determinations (LCD) for long-term EEG, continuous monitoring is indicated when a patient exhibits intractable seizures or diagnostic ambiguity that cannot be resolved by standard routine EEGs. The patient's clinical records demonstrate a documented history of refractory epilepsy with persistent, unexplained spells despite trials of multiple anti-seizure medications. Continuous long-term monitoring was clinically required to safely capture and characterize these events to direct critical treatment decisions. Because the medical record clearly establishes the necessity of this diagnostic modality over less intensive options, we respectfully request that this denial be reversed and the claim processed for payment.

Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].

We respectfully request that you reprocess this claim for payment.

Sincerely,

[Your Name]
