Summary & Overview
CPT 92512: Nasal Respiratory Function Test
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.
Billing Code Overview
CPT code 92512 describes a diagnostic nasal respiratory function test that measures airflow during inhalation and exhalation and records intranasal air pressure. This test evaluates nasal airway patency and function to help identify obstructive or functional nasal breathing conditions.

Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an otolaryngology clinic with chronic nasal obstruction, unilateral nasal congestion, and intermittent epistaxis. The clinician performs a focused history and nasal endoscopy, notes septal deviation and turbinate hypertrophy, and orders objective nasal airway testing to quantify nasal airflow and resistance. The service is scheduled in the outpatient ENT clinic. On the day of testing the patient is positioned supine or seated, a nasal cannula or face mask with pressure transducers is applied, and inspiratory and expiratory airflow and intranasal pressures are measured during quiet and deep breaths. Results are reviewed by the provider and used to document baseline nasal patency, support decisions about medical therapy (topical steroids, decongestants) or procedural interventions (septoplasty, turbinate reduction), and provide objective data for pre- and post-procedure comparison. Typical site of service: outpatient otolaryngology clinic or pulmonary function lab associated with an ambulatory surgery center. Service type: diagnostic nasal airflow and pressure testing measuring respiratory nasal function using objective instrumentation.
