// Policy Expansion and Cochlear Implant Utilization: A National Medicare Analysis (2012-2024)
分析顯示：2019/2022資格擴大後，2024年耳蝸植入（CI）5918件、PartB約2100–2200萬美元｜通膨調整後專業支付未見顯著增長，給付比率穩定；提供者增但均量不變｜資格擴大提升利用與分布，但制度與給付等障礙仍阻礙擴展。
// This study used a retrospective interrupted time-series analysis of national Medicare fee-for-service claims (CPT 69930, 2012–2024) to assess cochlear implant (CI) utilization, provider participation, billing distribution, and inflation-adjusted Medicare Part B professional payments after 2019 FDA and 2022 Medicare eligibility expansions. Inflation-adjusted professional payment per CI service did not increase significantly post-expansion (nonsignificant downward slope), and reimbursement ratios remained largely stable. Procedure volume and geographic billing distribution rose (5918 services and ~$21–22M total Part B payments in 2024) with more unique providers but stable mean provider volume; contemporaneous hypoglossal nerve stimulation showed rising reimbursement and use. Overall, eligibility expansions were linked to broader distribution and higher utilization but not to sustained per-service payment growth, suggesting other institutional, geographic, and reimbursement barriers limit scalable CI delivery.
