These rankings are pure-cost rankings. The quality dimension lives in the CMS Hospital Compare star rating shown alongside each entry; the combined-value grade on the right of the table aggregates both. For patients comparing hospital costs, the ranking is a useful first cut, but the procedure-specific page is the better tool: cost spreads vary by DRG code, and the all-procedure average can hide important per-procedure differences.
Across Hawaii's 24 Medicare-participating hospitals, the average payment per procedure is $21K, above the national average of $16K. 17% ofHawaii's hospitals carry a CMS quality rating of 4 stars or higher, and 8% earn an A or B on our Value Score, which weighs price (40%), quality (40%), and patient outcomes (20%).
Procedure prices in Hawaii range from Hale Ho'ola Hamakua at $13K per procedure to Molokai General Hospital at $30K — a difference of $17K on the same kinds of inpatient stays. Where you go for the same procedure can swing the bill by more than the procedure itself.
All numbers come from the latest CMS Hospital Compare release, which uses Medicare claims data and only reflects payments for Medicare inpatient stays — not what private insurers or self-pay patients actually pay. Star ratings combine seven groups of measures including mortality, patient safety, readmissions, and patient experience. Lower-priced hospitals can still earn an A on the Value Score if their quality stays competitive.
