CPT 95822: EEG Recording in Coma or Sleep Only
CPT code 95822 is a specialized billing code for electroencephalogram (EEG) recordings conducted exclusively in patients who are in a coma or asleep. This procedure is a critical tool in neurology, enabling clinicians to assess brain activity and diagnose conditions such as epilepsy, encephalopathy, convulsions, coma, and sleep disorders. The code is widely recognized and reimbursed by major national payers, including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare, reflecting its importance in clinical practice and coverage policies.
This publication provides a comprehensive overview of 95822, including payer coverage, clinical indications, and related billing codes. Readers will gain insight into the typical sites of service, such as hospital outpatient departments and neurology offices, and understand the role of EEG recordings in managing complex neurological conditions. The summary also highlights common modifiers used in billing, associated provider taxonomies, and relevant ICD-10 diagnoses. Additionally, comparisons to related CPT codes are included to clarify distinctions in EEG procedures. The article is designed to inform healthcare professionals, billing specialists, and policy analysts about current benchmarks, policy updates, and clinical context for EEG services under CPT code 95822.
CPT Code Overview
CPT code 95822 represents an electroencephalogram (EEG) recording performed in coma or sleep only. This procedure is a specialized neurological test used to monitor and evaluate brain activity in patients who are either comatose or sleeping. The service is typically provided within the field of neurology and electroencephalography, and can be performed in various settings, such as a hospital outpatient department or a neurology office. The EEG recording in these contexts is crucial for diagnosing and managing conditions affecting brain function during altered states of consciousness.
Clinical & Coding Specifications
Clinical Context
A patient is referred for an electroencephalogram (EEG) due to altered mental status, suspected seizure activity, or evaluation of sleep disorders. The EEG is specifically ordered to be recorded during coma or sleep only, as indicated by CPT code 95822. The procedure may occur in a hospital outpatient setting or a neurology office. The clinical workflow involves an EEG technician preparing the patient and monitoring the recording, while an electrodiagnostic medicine physician interprets the results. Typical scenarios include patients with unexplained coma, suspected encephalopathy, or sleep disturbances such as insomnia.
