CPT code 92512 denotes a diagnostic nasal respiratory function test that measures airflow and intranasal air pressure during inhalation and exhalation. This diagnostic procedure is used to assess nasal airway patency and identify functional or obstructive nasal conditions that can affect breathing, sleep, and quality of life. Nationally, the code matters because it supports objective assessment in otolaryngology, allergy, and respiratory care pathways and can influence diagnostic workflows and referral patterns.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for use of the code, typical sites of service, and common billing considerations. The publication summarizes available benchmarks, payer coverage patterns where available, and policy updates that affect coding and reimbursement for nasal respiratory function testing. It also outlines operational implications for outpatient clinics and diagnostic labs that perform objective nasal airflow and pressure measurements.

Data not available in the input for some fields; where detailed payer-specific rules, associated taxonomies, ICD-10 diagnoses, and related codes are required, readers should consult payer policy documents and clinical coding resources.
