Evaluation and Management (E/M) Services - Domiciliary or Rest Home Environment

Domiciliary, Rest Home, or Custodial Care Services CPT codes 99324 - 99337

Domiciliary, Rest Home (e.g. Boarding Home), or Custodial Care Services, are used to report E/M services to individuals residing in a facility which provides room, board, and other personal assistance services, generally on a long-term basis. 

These codes are also used to report E/M services in an assisted living facility. The facility’s services do not include a medical component.

A home or domiciliary visit includes a patient History, Physical Examination and Medical Decision Making in various levels depending upon a patient’s needs and diagnosis. 

The visits may also be performed as counseling and/or coordination of car, when medically necessary outside the office environment and are an integral part of a continuous of the patient's care. 

The patients seen may have chronic conditions, may be disabled, either physically or mentally, making access to a traditional office visit very difficult, or may have limited support systems. 

The home or domiciliary visit in turn can lead to improved medical care by identification of unmet needs, coordination of treatment with appropriate referrals and potential reduction of acute exacerbations of medical conditions, resulting in less frequent trips to the Hospital or Emergency services.

The home-based health care is rapidly expanding and growth in hospital-based house call programs. 

The Physicians and qualified non-physician practitioners (NPPs) are required to oversee or directly provide progressively more involving a great deal of worldly experience and knowledge of fashion and culture for home visits. 

A Patients must understand the nature of a pre-arranged visit and consent to treatment in the home or domiciliary care facility. There is no requirement that the patient must be homebound. 

If the service is provided to a patient for the first time, the patient, his/her delegate, or another medical provider managing the patient’s care, must request the service. The visiting provider may not directly solicit referrals. 

  • An example of inappropriate solicitation is knocking on residents’ doors or placing calls to residents on the telephone to offer medical care services when there has been no referral from another professional that is already involved in the case.

If laboratory and diagnostic tests are performed during the course of home or domiciliary care visits, they must be documented in the medically necessary reason. Medical reasons for repeat testing must be clearly documented.

Every page of the record must be legible and include appropriate patient identification information (e.g., complete name, dates of service[s]). 

The documentation must include the legible signature of the physician or non-physician practitioner responsible for and providing the care to the patient.

Many elderly patients have chronic conditions, such as hypertension, diabetes, orthopedic conditions, and abnormalities of the toenails. 

Required Criteria:

  • A home or domiciliary care visit must meet all of the following criteria.
  • Chief complaint or a specific, reasonable, and medical necessity is required for each visit.
  • A payable diagnosis alone does not support medical necessity of ANY service.
  • Medical necessity must exist for each individual visit.
  • Visit will be regarded as a social visit unless medical record clearly documents medical necessity for every visit.
  • Service/visit must be medically reasonable and necessary and not for physician or qualified NPP convenience.
  • Service must be of equal quality to a similar service provided in an office.
  • Frequency of visits required to address any given clinical problem should be dictated by medical necessity rather than site of service.
  • It is expected that frequency of visits for any given medical problem addressed in home setting will not exceed that of an office setting, except on rare occasion.

Telehealth Update Medicare - 2022

The listed CPT codes are covered in telehealth and changes are effective from dated on June 16, 2022 Medicare telehealth services require that the services occur over real-time audio and visual interactive telecommunications. For purposes of diagnosis, evaluation, or treatment of mental health disorders. If the patient doesn’t have the technical capacity or the availability of real-time audio and visual interactive telecommunications, or they don’t consent to the use of real-time video technology, we allow audio-only communication for telehealth mental health services to established patients located in their homes. After the PHE ends, Telehealth Mental Health services may include new or established patients so long as an in-person, face-to-face, non-telehealth service takes place within 6 months of the telehealth mental health services. This means that all telehealth mental health patients should have had a first in-person visit no later than 6 months after the PHE. After the PHE and a
