If someone is truly homebound, he/she would have a hard time from home out to a bus. Besides meeting Medicare regulations, including testing for water quality might be interesting if you drive the bus from place to place which would likely affect water quality. I have heard of a transportable dialysis "facility" in emergency situations. The best people to talk with about this would be your state survey agency.
I'd say if you want to look at helping homebound patients, promote PD or HHD. For those patients who do not have family members or friends to dialyze them, offering staff-assisted home dialysis would be a great help. However, Medicare does not pay for a helper (nurse or technician) and the Method II reimbursement (a supply company provides all equipment and supplies) pays the same for a patient on HHD as for one on CAPD which requires no machine. The only treatment that is reimbursed at a higher rate under Method II is CCPD. Method I home patients' care is reimbursed at the same amount per week as in-center patients' care is reimbursed per week. You can find the reimbursement amounts in our information on Medicare reimbursement for professionals from the home page.
