The four levels decide what Medicare pays the hospice, and which one applies changes with the day. Under 42 CFR 418.302(b), a routine home care day is a day the patient is at home and not receiving continuous care. A continuous home care day is a day of predominantly nursing care given on a continuous basis at home; 418.302(e)(4) requires a minimum of 8 hours of care in the day to qualify for that rate, and the regulation confines it to "brief periods of crisis". An inpatient respite care day is a short-term stay in an approved facility to relieve the caregiver. A general inpatient care day is inpatient care "for pain control or acute or chronic symptom management which cannot be managed in other settings". Paragraph (e)(2) allows payment for only one category on any given day.
A fifth item sits inside the first. 418.302(b)(1)(i) provides a service intensity add-on for routine home care days in the last 7 days of an election ending in the patient's death: an extra payment equal to the continuous home care hourly rate multiplied by the direct patient care actually provided by a registered nurse or social worker, up to 4 hours a day. It is a payment to the hospice rather than a charge to the family, and it is why staffing usually intensifies at the end.
The patient's own liability is two items, and that is the whole list. 42 CFR 418.400(a) sets coinsurance for each palliative drug or biological prescription furnished by the hospice while the individual is not an inpatient at approximately 5 percent of the hospice's cost for it, under a copayment schedule the hospice establishes, "except that the amount of coinsurance for each prescription may not exceed $5". That $5 is a fixed figure in the regulation, not an indexed one. 418.400(b)(1) then sets respite coinsurance at 5 percent of the CMS payment for a respite care day, and (b)(2) caps the total respite coinsurance in a hospice coinsurance period at "the inpatient hospital deductible applicable for the year in which the hospice coinsurance period began". Paragraph (b)(3) defines that period: it begins on the first day an election is in effect and ends at the close of the first 14 consecutive days on none of which an election is in effect. Note the asymmetry, because it is the practical one: respite coinsurance has an annual ceiling and drug coinsurance does not, though the $5 per-prescription cap keeps it small.
What "covered" actually includes is written out in 42 CFR 418.202, and it is broader than most families expect. Nursing care under a registered nurse's supervision. Medical social services. Physicians' services. Counseling provided to the patient and to family members or others caring for them, including dietary counseling, both to train the caregiver and "for the purpose of helping the individual and those caring for him or her to adjust to the individual's approaching death". Short-term inpatient care. Medical appliances and supplies including drugs "used primarily for the relief of pain and symptom control related to the individual's terminal illness", and durable medical equipment for use in the home. Home health or hospice aide services and homemaker services, with aides permitted to do household work "to maintain a safe and sanitary environment in areas of the home used by the patient". Physical, occupational and speech-language therapy for symptom control or to maintain activities of daily living. That list is the reason hospice at home can be dramatically cheaper for a family than the same weeks without it: the aide hours, the equipment and the medications all move onto the benefit.
Now the gap. Nothing in 418.202 is room and board, and the regulation governing hospices serving nursing facility residents says so from the other direction. 42 CFR 418.112(c)(4) requires the written agreement between the hospice and the facility to include "An agreement that it is the SNF/NF or ICF/IID responsibility to continue to furnish 24 hour room and board care". So for a patient living in a nursing facility or in assisted living, the monthly charge for living there continues, and hospice sits on top of it. Whether Medicaid picks up that facility charge for a dual-eligible resident is a Medicaid eligibility question rather than a hospice question, and our Medicaid and nursing home costs pages are where that belongs.
One aggregate limit that is easy to misread as a patient limit. 42 CFR 418.302(f)(1) caps total payment to a hospice for inpatient care, general and respite combined, so that inpatient days for its Medicare patients do not exceed 20 percent of the total days those patients elected hospice. That is a constraint on the hospice's aggregate payment at the end of a cap period, not a quota applied to any individual, and it should never be described to a family as a limit on their own days.
