CPT code 80417 covers stimulated renin measurement: lab analysis of renin levels in two peripheral blood samples drawn before and after a stimulant such as captopril. This diagnostic assay plays a key role in evaluating disorders of the renin-angiotensin-aldosterone system, including secondary causes of hypertension and some adrenal and renal conditions. As a specialized laboratory service, it impacts clinical decision-making, diagnostic pathways, and downstream care management nationally.

Key payers commonly involved include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a national overview of clinical context and coding usage for CPT code 80417, and outlines what readers can expect: benchmarks for utilization and site-of-service patterns, coding and billing considerations, and relevant clinical indications for stimulated renin testing. Practical information covers where the service is typically performed (clinical and hospital outpatient laboratories) and the types of clinical scenarios in which the test is ordered.

Readers will gain a concise reference on the definition and clinical purpose of CPT code 80417, payer coverage landscape at a high level, and the aspects of laboratory service delivery that affect billing and documentation. Data not available in the input.
