The demand for house calls is increasing because of the aging U.S. population, an increase in patients who are homebound, and the acknowledgment of the value of house calls by the public and health care industry. Literature from current U.S. home-based primary care programs describes health care cost savings and improved patient outcomes for older adults and other vulnerable populations. Common indications for house calls are management of acute or chronic illnesses, coordination of a post-hospitalization transition of care, health assessments, and end-of-life care. House calls may also include observation of activities of daily living, medication reconciliation, nutrition assessment, evaluation of primary caregiver stress, and the evaluation of patient safety in the home. Physicians can use the INHOMESSS mnemonic (impairments/immobility, nutrition, home environment, other people, medications, examination, safety, spiritual health, services) as a checklist for providing a comprehensive health assessment. This article reviews key considerations for family physicians when preparing for and conducting house calls or leading teams that provide home-based primary care services. House calls, with careful planning and scheduling, can be successfully and efficiently integrated into family medicine practices, including residency programs, direct primary care practices, and concierge medicine.

House calls, also referred to as home visits, are increasing in the United States.1 Approximately 40% of patient visits in the 1930s were house calls.1,2 By 1996, this decreased to 0.5% because insurance reimbursements for house calls decreased.1,2 The pendulum in the United States is swinging again to house calls because of the need to develop care models for the growing aging population.1,3,4 The proportion of house calls to outpatient clinic visits conducted by family physicians in the United States is unlikely to reach the 1930s levels; however, the number of house calls conducted from 1996 to 2016 doubled.3 Medicare Part B billing and reimbursement for house calls are also increasing, with nearly 2.6 million house calls paid in 2015.5

House Calls

There were more than 1,100 direct primary care practices in the United States in 2019, and 68% of these practices offered house calls, including eight practices that were completely mobile (i.e., had no actual office).

A systematic review of nine studies (N = 46,156) evaluating home-based primary care outcomes for homebound older adults reported fewer hospitalizations, hospital bed days of care, emergency department visits, long-term care admissions, and long-term bed days.

The increasing popularity of and call for home-based care have led to an increased need to study the outcomes and design of home-based primary care models in the United States. The two largest home-based primary care studies are the Centers for Medicare and Medicaid Services Independence at Home Demonstration and the U.S. Department of Veterans Affairs home-based primary care program.6,7 The Independence at Home program demonstrated a 23% reduction in hospitalizations, a 27% decrease in 30-day readmissions, and a cost savings of $111 per beneficiary per month, which is a $70 million savings over three years.710 Similarly, a large systematic review (N = 46,154; nine studies) evaluating home-based primary care outcomes for homebound older adults reported fewer hospitalizations, hospital bed days of care, emergency department visits, long-term care admissions, and long-term bed days of care.11 The U.S. Department of Veterans Affairs home-based primary care study of chronically ill, frail adults (N = 179) in urban populations also found fewer hospital admissions and bed days of care, but no change in emergency department use.12

House calls benefit patients post-hospitalization by reducing readmission rates, associated health care costs, and errors related to transitions of care.13,14 There is an increased need for home-based care for the most vulnerable populations because of the recent shift in the United States toward value-based health care.1,3 In 2011, there were 2 million homebound people in the United States, of which only 12% reported receiving home-based primary care.15 This number is expected to increase to 4 million by 2030.1

House calls also benefit patients with socioeconomic barriers to care, including pregnant patients and children who are at high risk of abuse.16 Nurse- or social worker–led home visiting programs have reduced child maltreatment, decreased child health care overutilization, and improved cognitive skills of children born to a low income household with limited psychological resources.1618 Outcome data for physician-led house calls are limited for younger populations because most data are from studies on older adults. A meta-analysis of 51 studies of home-based family care reported small, statistically significant improvements in child cognitive outcomes, maternal life outcomes, and parental behaviors and skills.19 Additionally, a Cochrane review of 11,000 newly postpartum patients receiving frequent in-home visits from interdisciplinary teams showed a decrease in infant health service utilization and an increase in maternal interest in exclusive breastfeeding.20

Historically, family physicians have been the workforce that meets the critical needs of the United States' most vulnerable populations. Family physicians need to learn how to incorporate house calls into their practices. The Accreditation Council for Graduate Medical Education requires family medicine residents to conduct house calls.21 Varying the type of calls and including patients with complex needs of all ages add training value that is consistent with the American Academy of Home Care Medicine clinical competencies.22 House calls, with careful planning and scheduling, can be successfully integrated into a busy office-based practice or residency program. Portable technologies, including electronic health records, battery-powered examination equipment, and point-of-care diagnostic testing, enable health care teams to bring office capabilities to patients' homes.1 This article provides tools for conducting house calls and reviews strategies for implementing house calls into a variety of outpatient practices, including residency programs, direct primary care (DPC), and concierge medicine models.

Conditions for the Initiation of House Calls

House calls may be needed for acute reasons because of a change in health status, serial visits for chronic conditions, or a one-time visit requested by caregivers or the physician to evaluate for a specific concern. The type of house call guides the goals and objectives for each patient encounter18 (Table 118,21,23,24 ). For older adults, consider assessing for geriatric syndromes (e.g., recurrent falls, polypharmacy, frailty, memory loss). Evaluation for suspected elder abuse, neglect, or self-neglect may provide valuable information. Illness or injury prevention house calls for frail, older, homebound adults should focus on preventing functional loss and avoiding hospitalization.18

Conditions for initiation
Patient is homebound (see Table 2)
Patient, family member, or member of the home health team requests a house call that is medically necessary, or the patient is willing to pay for a house call
Physician needs to negotiate care or clinical decision-making with the patient and caregivers
Physician needs to assess the home environment or patient and caregiver interactions
Physician needs to verify eligibility for third-party reimbursement for home health services
Required family medicine resident education*
Types
Concierge medicine service
Direct primary care visit
Family medicine resident education*
Family visit (e.g., well-child examinations and immunizations for multiple children; prenatal and postpartum visits)
Hospitalization follow-up
Illness and injury prevention for patients who are homebound (e.g., immunizations, patient home safety evaluation, strength conditioning, health promotion, disease prevention)
Illness management for patients who are homebound (e.g., emergency care, acute care, management of chronic conditions including rehabilitation services and palliative care for any stage of a serious, life-limiting illness)
Patient assessment* (e.g., polypharmacy, multiple medical problems, excessive health care use, social isolation, frailty, suspected abuse, suspected neglect or self-neglect, need for family meeting, recent major change in health, consideration for long-term care admission)
Patients who are dying (e.g., terminal care, death pronouncement, grief support)
Travel medicine

A patient who is enrolled in Medicare must meet two criteria to be considered homebound (Table 2).25 Most patients who are homebound have chronic medical conditions including heart failure, chronic obstructive pulmonary disease, renal failure, or advanced dementia. The goal of the house call for patients who have a chronic illness is to ensure safety at home, prevent exacerbation of symptoms, and evaluate caregiver burden and ability to care for the patient.18 Patients enrolled in Medicare who do not meet homebound criteria for home health care may be eligible for home-based primary care services. These services include hospital-based, veterans affairs–based, or freestanding home-based primary care that provides acute and chronic management of medical conditions, polypharmacy management, improved access to durable medical equipment, community resources for the patient and caregivers, and symptom management in end-of-life care.3 Medical necessity should be documented (i.e., frequently missed appointments, poor medication adherence, high use of emergency department services, or a need to assess function in the home environment).3

To be eligible for home health services, a Medicare beneficiary must meet both criteria
Criterion 1:
The patient must either:
 Because of illness or injury, need the aid of supportive devices such as crutches, canes, wheelchairs, and walkers; the use of special transportation; or the assistance of another person to leave their place of residence
or
 Have a condition such that leaving their home is medically contraindicated
If the patient meets one of the criterion 1 conditions, then they must also meet two additional requirements defined in criterion 2.
Criterion 2*:
There must exist a normal inability to leave home
and
Leaving home must require a considerable and taxing effort
Additionally, the following should not disqualify a person from being considered confined to the home:
 Participation in therapeutic, psychosocial, or medical treatment in an adult daycare program that is licensed or state certified
 Any absence of short duration for the purpose of attending a religious service
 Any absence for the need to receive health care treatment (e.g., ongoing outpatient kidney dialysis, outpatient chemotherapy, outpatient radiation therapy)
 Any other absence from the home that is infrequent or of relatively short duration
 For examples of homebound status, see the Medicare Benefit Policy Manual (Chapter 7, §30.1.1)

For patients reaching the end of life, care focusing on comfort (rather than function or longevity) is a common reason for house calls. Most patients with terminal cancer want to die at home; therefore, home care is a valuable service that helps reduce the likelihood of death in the hospital.18,2628 House calls made by family physicians for patients who are dying are primarily to provide symptom management such as pain relief for patients not using hospice services, and to provide psychosocial support to the patient and caregivers before death, and to family members and caregivers after the patient's death.29

Preparing for and Conducting House Calls

Previsit planning is essential to ensure the patient's maximum benefit from a house call. A member of the care team should call the patient in advance of arrival to verify the patient's availability and home address. Physicians should review the patient's medical record and medication list in advance, and bring a copy of the most recent information to the house for reconciliation during the visit. Once the physician is at the home, it is important to follow safety precautions (Table 330 ) to prevent personal injury or infection.18,30 Table 418,31 and Table 518,29,32 list recommended supplies for house calls.

Ask the patient in advance to cage their pets to avoid the risk of animal bites or other injuries
Avoid attracting unwanted attention when arriving and entering the home; consider leaving your white coat and expensive equipment at the office
Bring equipment for sharps handling and disposal that is in compliance with Occupational Safety and Health Administration Bloodborne Pathogens Standard
Call ahead to remind the patient of the visit; avoid surprising the patient, in particular those with weapons in the home
Coordinate house calls with other members of the multidisciplinary care team; alternatively, bring a learner (e.g., medical student, resident, nurse practitioner, physician assistant) or other office member for assistance and to enhance personal security by traveling as a team
During the house call, sit on nonclothed furniture, avoid pet droppings, wear gloves or respiratory masks if there is concern for environmental exposure or acute infections; use hand sanitizer before, during, and after the visit
Keep other trusted individuals (e.g., office staff members, partners, care team members) informed of the location and appointment time in the event that something does not go as planned
Preplan emergency and safety-concern codes (i.e., yes-or-no questions) with another person; these codes should alert that person to send emergency personnel to your location if needed
Schedule check-ins with a designated person on arrival and after completion of the visit
Travel in a well-maintained vehicle appropriate for anticipated terrain and weather conditions

If needed, a house call checklist, such as the INHOMESSS mnemonic (impairments/immobility, nutrition, home environment, other people, medications, examination, safety, spiritual health, services; Figure 1), can be used as a guide for performing a complete geriatric assessment.18 A typical approach begins with observing how the patient enters their home and evaluating for transitions of flooring in entryways and the need for extra grab handles, ramps, or rails. Once inside the home, begin by addressing any urgent patient concerns, then shift the conversation to focus on the items found on the checklist if time permits. This process typically takes 45 to 90 minutes, and frequent breaks are common.

Allocate time to review the patient's prescribed medications, herbs or supplements, and over-the-counter medications. The patient or caregiver should show the physician where these medications are kept and organized to provide further insight into medications that may not have been mentioned, issues with compliance, and identification of stockpiles of old or expired medications. Laying out the medications is recommended to perform true medication reconciliation, in addition to checking for drug-drug interactions.

While the patient is still seated, check vital signs, and perform a focused examination. Once that is completed, the physician should observe the patient as they stand and note if they have difficulty changing positions, need an assistive device to stand (e.g., chair with arms, cane), and how they move around the house (e.g., with a walker, cane, grasping onto furniture). Ask permission to follow the patient through the most frequented areas of the house while observing the patient's gait and noting any balance issues. Looking for transitions in flooring; stairwells; rug placement; pathway obstructions; height of chairs, bed, and toilet; type of showers (walk-in vs. tub); and location of smoke detectors, fire extinguishers, and firearms helps provide an understanding of the patient's functional status and identify potential patient safety and fall hazards (Table 6).18

Provide written safety recommendations to the patient and caregiver addressing all urgent concerns and provide additional comments based on findings from the completed checklist. Some durable medical equipment recommendations, such as hospital beds, may be covered by insurance, including Medicare Part B; however, other equipment, such as grab bars or shower chairs, is not typically covered by insurance. The use of assessment tools (Figure 118 ) can be incorporated into the house call based on the complexity of the patient's condition, the time allowed, and the purpose of the visit. Having an in-depth discussion of end-of-life care choices, guided by the patient's goals, may be appropriate, even if they have already been addressed in a clinic or hospital setting. End-of-life care choices should be confirmed or readdressed as the patient's health care situation changes. Providing prescriptions, supplies, handouts with helpful websites, or local resources communicates further support to the patient and caregivers.

Incorporating House Calls into Office-Based Practice

The benefits of house calls are substantial for physicians and their patients. Physicians experience a change of pace from typical clinic appointments, and house calls can provide additional important information about the patient, including insight into a patient's actual home situation, medication management, diet, and overall lifestyle. Patients report experiencing peace of mind, increased respect and trust in their physicians, and better access to care after a house call.2,4,33

However, integrating house calls into office-based practice is challenging. Barriers include geography, travel time, and perceived loss of revenue.18 Grouping house calls together within a half-day, grouping locations, and conducting the visits after the conclusion of a clinic day may minimize this barrier. A multidisciplinary strategy for house calls can help decrease physician burden and improve care. The care team commonly includes a customized combination of a physical therapist, occupational therapist, speech therapist, dietician, licensed social worker, clinical pharmacist, licensed practice/vocational nurse, registered nurse, psychiatric nurse, wound care nurse, and nurse practitioners or physician assistants. With a multidisciplinary team, improved tracking and scheduling of patients can optimize time management, allowing for greater spacing and efficiency of physician visits, and can decrease loss to follow-up.

A travel bag, dedicated house call vehicle, and a mobile office are tools that help keep house calls organized. Besides regular office equipment needed for a focused examination and gathering vitals, an emergency supply kit (Table 518,29,32 ) may be useful. House calls for dying patients are unique because of the symptoms and treatment needs specific to that population. American Family Physician has previously published an article on managing common symptoms in end-of-life care.29 Additional specialized equipment may be necessary based on the patient's needs (Table 418,31 ). It is important to have a good understanding of patients' individualized needs and commit to goals for the visit in advance. When applicable, physicians should provide educational materials, medication reconciliation forms, do-not-resuscitate and do-not-intubate forms, out-of-hospital resuscitation forms, home health forms, and hospice-required documents.18

Documentation for a house call is similar to that for an office visit. A note template can help with consistent documentation and serve as a checklist (eFigure A). Recommendations for continued care and changes to the care plan should be included in the documentation with proper coding and billing information (eTable A).

CPT codes 99341 – 99350 are home service codes used to report evaluation and management services provided to a patient residing in their own private residence (POS code 12).

Direct Primary Care and Concierge Medicine House Calls

DPC is an innovative practice model that offers patients a variety of primary care services for a low, periodic membership fee.34,35 Integrating house calls into this type of practice may be easier because the DPC model enables physicians to spend more time with patients, and DPC physicians typically have smaller panel sizes. According to Phil Eskew, DO, founder of DPC Frontier, there were more than 1,100 DPC practices in the United States in 2019, and 68% of these practices offered house calls, including eight practices that were completely mobile (i.e., had no actual office). House calls may be included as part of the membership, or DPC physicians may charge a flat rate or a variable amount based on travel time or mileage.36

Although DPC physicians often provide house calls to older adults and to patients who are disabled, terminally ill, and to patients who are homebound, some physicians may also offer newborn visits and well-child examinations. Additionally, house calls are commonly made for sick visits and postoperative care. Large families or families with young children may benefit from house calls because of the convenience and comfort of seeing multiple members at once in a familiar and safe environment. DPC physicians report that offering house calls is useful for recruiting new patients, and families appreciate the home-based service.

Concierge practices also routinely offer house calls but charge higher membership fees and may continue to bill insurance for covered services.37 Concierge practices may also provide hotel calls for travelers seeking more personal, convenient care.
