Readers will find a concise overview of the clinical context for S9024, payer coverage considerations, common billing modifiers, and benchmarking expectations where available. The publication outlines how the service is typically delivered (outpatient imaging centers, office-based clinics, hospital outpatient departments) and highlights operational and documentation points that influence reimbursement and claims processing.

This summary frames the practical use of S9024 for administrators, coders, and clinicians seeking a national perspective on coding practice, payer engagement, and the clinical role of paranasal sinus ultrasound.
