The Medicare Payment Advisory Commission (MedPAC) has published the 2023 Data Book Health Care Spending and the Medicare Program, which provides information on national health care and Medicare spending as well as Medicare beneficiary demographics, dual-eligible beneficiaries, quality of care in the Medicare program, and Medicare beneficiary and other payer liability. It also examines provider settings — such as hospitals and post-acute care — and presents data on Medicare spending and beneficiaries’ access to care in the setting (measured by the number of beneficiaries using the service, number of providers, volume of services, length of stay, or through direct surveys). Specifically of interest is information on dual-eligible beneficiaries, including individuals with disabilities, and information on alternative payment models.
