Katie is a 31-year-old waitress with an annual income of $15,800 who has end-stage renal disease (ESRD) and hypertension. Though she is under 65, her ESRD qualifies her for Medicare. Six months ago, Katie had a kidney transplant and continues to take anti-rejection medication (also known as immunosuppressants), in addition to medication for her hypertension. She does this with the help of her Medicare Part D prescription drug coverage, which assures access to “all or substantially all” medications within six specific classes of medicines, including immunosuppressants.
