Here you go:
A study in Health Affairs examined claims data from a large national insurer for 316,244 women whose employers switched insurance coverage from low-deductible health plans (i.e., deductibles of $500 or less) to high-deductible health plans (i.e., deductibles of $1,000 or more) between 2004 and 2014. Women with low incomes who had high-deductible insurance plans waited an average of 1.6 months longer for diagnostic breast imaging, 2.7 months for first biopsy, 6.6 months for first early-stage breast cancer diagnosis and 8.7 months for first chemotherapy, compared with low-income women with low-deductible plans.
Wow, who saw this coming?
Maybe this data would change if these patients could actually shop around for realistic prices for breast imaging, biopsies and chemotherapy?
