What is the calculation unit used in the Home Health Prospective Payment System?

The calculation unit used in the Home Health Prospective Payment System (HH PPS) is the Home Health Groupings Model (HHGM), which is designed to categorize patients into distinct groups based on clinical characteristics and other factors. This approach involves a case-mix adjustment that reflects the severity of the patient's condition and the expected costs of providing care.

By utilizing a case-mix adjustment, the HH PPS ensures that reimbursement is aligned with the resources needed to deliver care to diverse patient populations. This method of grouping allows for a more accurate and fair assessment of the services required, which helps in determining appropriate payment amounts for home health agencies based on the specific needs of their patients.

In contrast, other options like patient resource groups and daily service rates do not accurately capture the complexity and variability present in home health care needs, making them less suitable for establishing a reimbursement model. The emphasis on case-mix adjustment is crucial in promoting efficient and effective use of resources in home health services.
