These are averages over each hospital's Medicare stays in this DRG, which mix simple and complicated cases. A high average charge is the hospital's pricing, not a sign of better or worse care, and not what a patient pays: Medicare patients owe the inpatient deductible, and people with other coverage pay their plan's negotiated rate.
