Case-mix indexes: do they adversely affect some hospitals?

D Palmer

    Healthcare Financial Management : Journal of the Healthcare Financial Management Association
    |June 9, 1985
    PubMed
    Summary

    The 1981 case mix indexes used for hospital payments under PPS can be arbitrary due to data issues. Hospitals should review these indexes and object if negatively impacted to preserve appeal rights.

    Area of Science:

    • Health economics
    • Hospital administration
    • Healthcare policy

    Background:

    • The Prospective Payment System (PPS) relies on case mix indexes to determine hospital-specific payment amounts.
    • The 1981 case mix indexes are currently used in this process.
    • Potential inaccuracies in these indexes may lead to arbitrary payment determinations.

    Purpose of the Study:

    • To evaluate the fairness and accuracy of using 1981 case mix indexes for PPS hospital payments.
    • To identify the potential negative impacts of these indexes on hospitals.
    • To advise hospitals on how to address adverse effects and preserve appeal rights.

    Main Methods:

    • Analysis of the 1981 case mix indexes and their application in PPS.
    • Identification of factors contributing to unreasonable results, such as random variation, data errors, and service changes.
    • Review of hospital cost reports and objection procedures.

    Main Results:

    • The use of 1981 case mix indexes can lead to arbitrary and unreasonable payment amounts for some hospitals.
    • Random variation, data errors, and changes in hospital services contribute to these inaccuracies.
    • Hospitals may be unfairly reimbursed due to the limitations of these indexes.

    Conclusions:

    • Hospitals facing adverse effects from the 1981 case mix indexes should formally object.
    • Preserving appeal rights is crucial for hospitals when filing PPS cost reports.
    • A review of the impact of these indexes is recommended for all affected hospitals.
