Summary & Overview
CPT 4328F: Assessment of Sleep Disorders in Parkinson’s Disease
CPT code 4328F denotes a provider inquiry about sleep disorders in patients with Parkinson’s disease, documenting that sleep-related symptoms were assessed to inform treatment planning. Sleep abnormalities are a common and clinically important aspect of Parkinson’s disease, affecting quality of life and treatment choices. Nationally, documenting sleep assessments supports comprehensive care coordination for a growing population of patients with neurodegenerative disease.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, typical service settings, and what documentation this code represents. The publication summarizes how the code fits into outpatient neurology and sleep-medicine workflows and highlights policy- and billing-related considerations that commonly affect reimbursement and claims accuracy.
This publication provides benchmarks and practical guidance on where to look for policy updates, clarifies clinical scenarios when a sleep-focused assessment for Parkinson’s patients is relevant, and outlines documentation points that payers commonly review for claims containing 4328F. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 72-year-old man with a 7-year history of Parkinson’s disease presents to a neurology clinic complaining of fragmented sleep, vivid nightmares, and excessive daytime sleepiness that have worsened over the past year. His movement disorder is managed with dopaminergic therapy, and medication review suggests nocturnal motor symptoms and possible REM sleep behavior disorder. The provider obtains a focused sleep history, screens for REM sleep behavior disorder, obstructive sleep apnea, restless legs syndrome, insomnia, and medication-related sleep disturbances. The clinical workflow includes: history taking focused on sleep timing, motor symptoms at night, dream enactment, and daytime function; review of Parkinson’s medications and timing; brief validated screening questionnaires as indicated (for example, REM sleep behavior disorder screening or Epworth Sleepiness Scale); consideration of home sleep testing or polysomnography if obstructive sleep apnea or REM behavior disorder is suspected; coordination with sleep medicine, neurology, and the patient’s primary care clinician; documentation of findings, differential diagnosis, and a plan for symptomatic management, medication adjustment, or referral. Typical site of service is an outpatient neurology or sleep medicine clinic visit within a hospital-owned or independent clinic setting.
