Inpatient vs Outpatient Hospital Status
In an effort to detect and reduce Medicare waste, fraud and abuse, the Centers for Medicare and Medicaid Services (CMS) has increased scrutiny on the medical necessity of a one-day length of stay for inpatient admissions to hospitals. In response to this, ECRMC is now screening inpatient admissions for medical necessity, and educating patients and their family members and providers, nurses, administration and other staff on the medical necessity requirements for inpatient status. The result has been an increase in the number of outpatient observation patients and an increase in confusion on what the differences are between inpatient vs. outpatient (observation) status. Below are questions and answers on CMS’s guidelines for inpatient vs. outpatient (observation) status, which will hopefully help you become more familiar with what they both mean.
Did you know that even if you stay in the hospital overnight, you might still be considered an outpatient observation status?
Your hospital status (“inpatient” or “outpatient/observation”) affects how much your insurance pays and what you pay for your hospital services – such as X-rays, drugs, lab tests, etc. Each status carries a different co-pay or percentage of coverage. If you are on a Medicare plan, your hospital status may also affect whether Medicare will cover your care in a skilled nursing facility (nursing home) following your discharge from the hospital.
Your health care team, which includes physicians, nursing staff, and hospital case management staff (Utilization Management), reviews the medical record for the clinical information and applies the research-based clinical criteria utilized by CMS that provides a recommendation for either “outpatient” or “inpatient” status.
Your physician determines the final status; however, if Medicare does not agree with the determination, Medicare will not reimburse the hospital for costs incurred. The hospital costs may then be billed to the patient.
Physicians and hospitals follow a specific set of clinical criteria (severity of illness and intensity of service needed to diagnose and treat) that assists in determining whether a patient meets medical necessity for an “inpatient” status in the hospital. The Centers for Medicare & Medicaid Services (CMS) has specific guidelines (medical necessity) on whether a patient should be Inpatient or Outpatient/Observation – depending on how severe the patient’s symptoms/condition is and how quickly they may respond to treatment.
“Outpatient” status is commonly referred to as patients who typically go to an outpatient department such as laboratory, radiology or to the Emergency Department for diagnostic services. Your physician may write an order for you to be admitted as an outpatient/observation patient at Winston Medical Center. The observation stay is intended for short-term diagnostic testing and monitoring, which are reasonable to evaluate your condition. This is done in order to determine your need to be admitted to the hospital as a hospital patient or be discharged to go home.
Specific criteria (based on severity of illness and intensity of service) must be met in order to admit a patient to the hospital. In some cases, it is not clear whether you are well enough to go home or if hospitalization is needed until further testing/evaluation is completed.
Medicare Part A (hospital insurance) covers inpatient hospital services. Generally, this means you pay a one-time deductible for all of your hospital services for the first 60 days you’re in the hospital. If you are hospitalized again after 60 days, Medicare may apply another deductible.
Medicare Part B (medical insurance) covers most of your physician services when you’re an “inpatient.” You pay 20% of the Medicare-approved amount for physician services after paying the annual Part B deductible.
Can a patient be an "outpatient" anywhere in the hospital, even if they were told they were being admitted to the hospital?
Yes. A patient can be receiving any service anywhere in the hospital (Radiology, Emergency Department, or nursing floor) and still be considered an “outpatient,” according to CMS guidelines. The term “outpatient” is used by Medicare and other insurance companies for billing status only, not patient care status.
Medicare Part B covers outpatient hospital and physician services. Generally, this means you pay a copayment for each individual outpatient hospital service. This amount may vary by service.

Why is it important to know if a patient is an "inpatient" vs. "outpatient/observation" status, no matter if they are on Medicare or not?
If you or a family member is in the hospital more than a few hours, always ask the physician or hospital staff if you’re an “inpatient” or “outpatient/observation” because it WILL affect how you are billed and what you will have to pay for out-of-pocket.
How does "inpatient" vs. "outpatient observation" status in the hospital affect the way that Medicare covers care for the patient in a skilled nursing facility (or nursing home)?
Medicare requires a “qualifying hospital stay” in order for Medicare A to cover care within a skilled nursing facility. A qualifying hospital stay is defined as a hospital “inpatient” for a minimum of three (3) days in a row – counting the day you were admitted as an inpatient, but not counting the day of your discharge.
For example, a physician may have determined that a patient be on “outpatient observation” status to help decide whether the patient needs to be admitted to the hospital as an “inpatient” or whether they should be discharged. During this time, the patient is still considered an “outpatient,” even while receiving hospital services, which may include staying overnight multiple nights.
If you are still on an “outpatient observation” status, even if you have a 3-day stay in the hospital, Medicare will not count this time toward the required 3-day minimum hospital stay for your stay in a Skilled Nursing Facility. If you are ready for discharge, you may need to either pay part of your stay at a Skilled Nursing Facility or ask for other options for payment. The hospital discharge planner or Social Worker can assist you and your family with these decisions.
If a patient has been in the hospital over 24-hours, do they get changed from "outpatient/observation" to "inpatient" status?
No. A patient status is only changed if they meet full “inpatient” medical necessity/severity of illness criteria.
