Hospital-at-Home

A participating hospital admits the patient to a home-based inpatient unit rather than a bed. The model combines daily physician or advanced practice oversight (often virtual), scheduled in-person visits from nurses or community paramedics, remote patient monitoring of vital signs, rapid-response capability, and logistics for medications, labs, imaging, and equipment in the home. Typical diagnoses include heart failure exacerbations, COPD, pneumonia, cellulitis, and other conditions that need acute-level treatment but not an ICU. Studies of the model have generally shown comparable or better outcomes, fewer complications, and high patient satisfaction relative to traditional inpatient stays.

CMS launched the Acute Hospital Care at Home waiver in November 2020 during the public health emergency, allowing approved hospitals to be paid full inpatient rates for at-home acute care while waiving certain hospital conditions of participation, including 24/7 on-premises nursing. Congress has continued the program since then through a series of short-term statutory extensions rather than a permanent authorization, so the program's future remains subject to congressional action. Hundreds of hospitals across dozens of states have been approved to participate. Agencies building strategy around hospital-at-home should verify the waiver's current status and any legislative developments before committing capital.

Home health agencies intersect with the model in two ways. First, as delivery partners: hospitals running these programs need in-home nursing capacity, and many contract with home health agencies to supply visits under arrangement, paid by the hospital rather than billed to the home health benefit. That creates a revenue line independent of PDGM. Second, as the downstream referral channel: hospital-at-home patients still need skilled care after the acute episode ends, and the agency already in the home is the natural referral. Partnering also embeds the agency deeper into the health system relationship, which tends to pull traditional referrals along with it.

The two are frequently confused and fundamentally different. Hospital-at-home is an inpatient admission delivered at home: acute-level care, hospital payment, hospital conditions of participation, and hospital accountability. The Medicare home health benefit covers intermittent skilled care for homebound patients under a plan of care, paid through the home health PPS in 30-day periods. Eligibility rules, payment, staffing intensity, and regulatory oversight all differ. An agency describing itself as offering hospital-at-home when it means high-acuity home health invites confusion with referral sources and regulators alike; precision here is a credibility signal.
