Hospital-at-Home and the CMS waiver

What the waiver does

Hospital eligibility

To bill under AHCAH, the hospital must apply to CMS for a waiver and demonstrate that it can deliver inpatient-equivalent care safely in the home setting. The application requires evidence of an established care coordination model, capability to provide a defined set of services in the home, screening criteria for patient selection, and an adequate plan for emergencies that arise during a home admission.

CMS publishes a list of approved hospitals on its site. Programs entering the space typically partner with an experienced hospital-at-home provider or build the operational capability internally before submitting.

Patient eligibility

Patients must require inpatient-level care and be screened for both medical and psychosocial appropriateness. The screening typically considers the patient's clinical condition and stability, home environment safety, presence of a caregiver where indicated, technology literacy needed for any remote-monitoring devices, and access to reliable transportation and communications.

Programs vary in how they apply eligibility criteria. The minimum service set required by the waiver includes daily evaluation by a physician or advanced practice provider, two daily nursing visits or one nursing visit plus a remote-monitoring touchpoint, ability to deliver medications and equipment to the home, and rapid-response capability for acute clinical changes.

Billing posture

The billing model under AHCAH is straightforward in concept: the hospital bills the standard inpatient DRG, with the home admission counted as inpatient days. The complexity is in the operational data flow that supports the billing claim.

For each home admission, the program must be able to document the daily provider evaluation, the nursing visits, the remote-monitoring data, the medication and equipment delivery, and any escalations. Coordination data flowing back into the EHR matters because the inpatient claim depends on the documentation. Programs that built their dispatch and documentation pipelines together typically have an easier audit posture than programs that bolted documentation on after the fact.

Quality and reporting

CMS requires participating hospitals to report on a defined set of quality measures, including mortality, escalation to higher-acuity care, and patient experience. Programs are also expected to participate in CMS evaluation activities. The published evaluations of the program have generally found favorable patient experience and acceptable safety profiles, with comparable or lower escalation rates against matched inpatient cohorts.

What policy uncertainty means for new programs

The waiver has been extended multiple times but is not permanent. Programs starting today should plan for a near-term horizon in which the policy is renewed and a longer-term horizon in which the program may need to operate under a permanent rule that has not yet been finalized.

Operationally, the right posture is to build a program whose operations are robust to policy changes: a clean separation of clinical capability, dispatch infrastructure, and billing posture. Programs that conflate the three tend to be the ones disrupted hardest by regulatory changes.
