Persistent challenges in cervical cancer (CC) control highlight the need for stage-specific cost estimates to refine prevention strategies. Structural integration of National Health Insurance (NHI) administrative claims, the Taiwan Cancer Registry (TCR), and the National Cause of Death Registry (NCDR) provided the empirical basis for this population-based research. The final analytical sample encompassed 6055 women with cervical intraepithelial neoplasia (CIN) identified in 2016 as well as 9318 patients diagnosed with stage I to IV invasive CC during the 2008 to 2015 period. Reimbursed direct medical costs were estimated for CIN within 6 months after diagnosis and for CC over 5 years after diagnosis. Across CIN grades, no consistent cost gradient was observed, although inpatient utilization was highest in CIN3. Among women with CC, healthcare utilization and expenditures were concentrated in the first year after diagnosis, accounting for 52–65% of the total 5-year costs. After age adjustment, the mean first-year costs increased from NT256, 095 (US8413) in stage I to NT474, 724 (US15, 595) in stage IV, while 5-year survival declined from 85. 3% to 19. 5%. These findings show that cervical disease imposes substantial direct medical costs on Taiwan’s healthcare system and provide updated evidence to inform human papillomavirus (HPV) vaccination and CC screening policy.
