Inpatient Care and Medical Equipment
Hospices report these services to Medicare when they are certified. This is what ST. MARY'S HOSPICE, INC reported, not a check of what it offers today. Confirm current arrangements with the hospice.
An older Medicare record for this hospice lists short-term inpatient care as “not provided.” That code may be out of date. Medicare requires certified hospices to make inpatient care available for symptom management and caregiver respite. Ask this hospice how it arranges a bed if symptoms become hard to manage at home.
- Medical supplies and equipment
- Brought in through an outside supplier
Equipment and supplies tied to the terminal illness and the plan of care, such as a hospital bed, oxygen, wound supplies, or a wheelchair.
Medicare lets hospices provide these services through arrangements with other organizations. Either way, the hospice stays responsible for the covered care in the patient’s plan of care.
