Custodial care is personal care and supervision that helps a person with the basic tasks of daily life, such as bathing, dressing, eating, using the bathroom and moving from a bed to a chair, as opposed to skilled medical or rehabilitative care. Medicare's own consumer site, Medicare.gov, uses the term interchangeably with long-term care: "Long-term care (also called 'custodial care' or 'long-term services and support') includes medical and non-medical care for people who have a chronic illness or disability. Most long-term care helps with basic personal tasks of everyday life, sometimes called 'activities of daily living.'"
The term carries most of its weight in Medicare. The program's list of excluded services includes "Custodial care, except as necessary for the palliation or management of terminal illness," and defines it by what it is not: "Custodial care is any care that does not meet the requirements for coverage as SNF care." The same help with bathing and dressing can therefore be covered for a few weeks during a skilled nursing stay and not covered at all once the skilled need ends.
