If you’re looking for relevant Medicare data, you might find it in the Medicare Payment Advisory Committee’s recent data compilation, “A Data Book: Health Care Spending and the Medicare Program.” For example: Spending on home health services comprised 4 percent of overall Medicare spending in 2009, versus 3 percent in 2018, the data book indicates. A link to the data book is at www.medpac.gov/-documents-/data-book.
