Based on the data, CPT 84439 shows a 1.0x variation in pricing across states — relatively consistent by Medicare standards.
Costs have decreased 25.6% since 2014. Medicare's fee schedule attempts to standardize pricing, though some variation is expected due to geographic cost-of-living adjustments and practice expense differences.
This analysis is based on publicly available CMS data and does not account for patient complexity, comorbidities, or facility-specific factors that may justify pricing differences.
