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.
