Summary & Overview
CPT 94200: Maximal Voluntary Ventilation Pulmonary Function Test
CPT code 94200 describes maximal voluntary ventilation (MVV), a pulmonary function test that measures the largest volume of air a patient can move while breathing as deeply and rapidly as possible for a set interval. Nationally, MVV is used to help identify obstructive and restrictive lung disease and to evaluate respiratory reserve before surgical procedures, making it relevant to pulmonology, preoperative assessment, and respiratory therapy services.
Key payers included in this overview are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical and billing-focused briefing that covers the test’s purpose, typical sites of service, and payer relevance. The publication outlines billing benchmarks where available, common billing modifiers and their use cases, and the clinical context that informs appropriate ordering of MVV testing.
This summary is intended for clinicians, billing managers, and policy professionals seeking a concise reference on CPT code 94200, including coding context, payer landscape, and practical considerations for integrating MVV testing into respiratory care pathways. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 94200 documents measurement of the largest volume of air a patient can voluntarily breathe while breathing as deeply and quickly as possible for a specified period. This test evaluates pulmonary function to help determine obstructive and restrictive lung disease and to assess lung condition and strength prior to surgery.
Service Type: Pulmonary function testing — maximal voluntary ventilation (MVV)
Typical Site of Service: Hospital outpatient department, pulmonary function laboratory, or physician office
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of chronic smoking and progressive exertional dyspnea is referred to pulmonary function testing to evaluate for obstructive lung disease. The patient presents to an outpatient pulmonary function laboratory at an ambulatory clinic or hospital-based respiratory therapy department. After registration and review of recent medical history and medications, a respiratory therapist explains the procedure and obtains informed consent. The patient is seated and fitted with a nose clip and a tight mouthpiece seal. The provider instructs the patient to breathe as deeply and rapidly as possible for the specified timed maneuver while using a calibrated spirometer to record the largest volume of air exhaled and inhaled during the forced series. Results are reviewed by the interpreting clinician to assess for obstructive and restrictive patterns, bronchodilator response, and preoperative pulmonary risk assessment. Typical sites of service include hospital outpatient departments, ambulatory surgery centers, and dedicated pulmonary function labs in physician offices prior to elective surgery or as part of chronic respiratory disease management.
