Hospital logistics: what it is, how it works and how to improve it

Home hospitalization, or home care, is a care model in which the patient receives at home the same level of care they would receive in a hospital bed. For the hospital, it is an alternative that frees up high-complexity beds. For the payer, it can mean lower costs when well managed. For the patient, it can mean recovery in a more comfortable setting with a lower risk of hospital‑acquired infection.

But home hospitalization is not a simplified model of care: it is an extension of the hospital into the home, with the same safety, documentation and billing requirements. Hospitals that do not structure this process correctly face denials for incomplete documentation, coverage refusals and inconsistencies between what was provided and what was charged.

What home hospitalization is and when it is authorized

ANS Normative Resolution No. 465/2021 (ANS is Brazil’s National Supplementary Health Agency) defines home hospitalization as the set of activities provided at home, characterized by full-time care for patients with a more complex clinical condition who need specialized technology. This definition establishes that home care replaces a conventional hospital stay; it is not a complement to it.

For home hospitalization to be authorized, three conditions must be met at the same time:

• an express indication from the attending physician, with a detailed treatment plan;

• the patient’s clinical stability, so that they can be safely transferred to the home environment;

• suitability of the home, which must have the infrastructure needed for the prescribed care, including equipment, access to supplies and caregiver support when indicated.

Home hospitalization is different from simple home care services, such as wound dressings or nursing visits, and from low-complexity palliative care. The distinguishing criterion is the need for specialized technology and full‑time care.

The health plan’s obligations

Article 13 of RN No. 465/2021 establishes that, when the payer offers home hospitalization in place of a hospital stay, it must comply with all the requirements of the current rules of Anvisa (National Health Surveillance Agency) and guarantee the plan member the same breadth of coverage they would have in the hospital.

In practice, this means that a patient in substitute home care must have access to the same supplies, medications, multidisciplinary team and equipment they would have in a conventional hospital stay. The payer cannot offer home care as a cheaper alternative to reduce coverage of the items needed for treatment.

When the health plan contract does not explicitly provide for home care, but the payer decides to replace the hospital stay with this model, it assumes full responsibility for the treatment. In this context, a coverage denial for items needed for the treatment plan prescribed by the attending physician has no regulatory basis.

Billing and documentation in home hospitalization

Billing for home hospitalization follows the same logic as a hospital stay in terms of documentation requirements, with some features specific to the model. Every supply, medication and procedure must be recorded in the medical record, linked to the treatment plan and authorized by the payer.

The medical record in home care is especially critical because care is provided outside the hospital structure, by teams that work in rotation and do not always have access to the hospital’s central system. Fragmented records, unsigned prescriptions or incomplete clinical progress notes are frequent causes of denials for incomplete documentation in this type of hospitalization.

Continuous-use medications in home care, especially high-cost ones, require a valid prior authorization for each administration period. The original authorization for the hospitalization does not automatically cover all the medications in home treatment: each restricted-use item needs its own authorization.

Concurrent auditing, carried out during the hospitalization, is particularly important in home care because the physical distance between the patient and the billing team increases the risk of documentation gaps. A concurrent audit process adapted to home care remotely checks the home teams’ records and identifies inconsistencies before the claim is closed.

The impact of technology on home care management

Coordinating care in the home model is a logistical and clinical challenge. With dispersed teams and decentralized records, data integration is what guarantees continuity of care and billing traceability.

Using interoperability standards such as FHIR allows the medical record filled in by the nurse at the patient’s home to be viewed in real time by the attending physician and the audit team, ensuring that care is continuous and that billing for supplies and medications reflects what was actually provided.

For a hospital that provides home care services, integration between the home care system and the billing system is what eliminates the model’s main risk: a discrepancy between what was done in the home and what reached billing.

Frequently asked questions about home hospitalization

What is home hospitalization?

It is the care model in which the patient receives at home the same level of care they would receive in a conventional hospital stay, including full-time care, a multidisciplinary team and specialized technology. ANS Normative Resolution No. 465/2021 defines home care as a replacement for a hospital stay, not a complement to it.

Is the health plan required to cover home hospitalization?

When the payer offers home care as a substitute for a hospital stay, it is required to guarantee the same breadth of coverage the patient would have in the hospital, under Article 13 of RN No. 465/2021. If the contract does not explicitly provide for home care, but the payer decides to replace the hospital stay, it assumes full responsibility for the treatment.

What are the requirements for home hospitalization to be authorized?

Three conditions must be met: an express indication from the attending physician with a detailed treatment plan, the patient’s clinical stability to be safely transferred home, and a suitable home environment with the infrastructure needed for the prescribed care.

How can denials be avoided in home care billing?

The main measures are: keeping the medical record complete and updated in real time, ensuring a valid prior authorization for each restricted-use medication, carrying out concurrent auditing adapted to the home model and integrating the care system with the billing system. Documentation gaps are the main cause of denials in this model.
