Observation Status Hospital Stay in New Jersey
The Difference Between Inpatient and Observation Status
Your parent can spend three days in a hospital bed, receive IV medications, undergo imaging, and see a specialist — and still not be an "inpatient." Observation status means the hospital is treating your parent as an outpatient. They occupy a bed, but their stay is billed under Medicare Part B rather than Part A.
The distinction matters because Medicare Part A covers the first 20 days of skilled nursing facility (SNF) care at no cost after a qualifying hospital stay. Part B does not. If your parent is classified as observation the entire time, they will not qualify for Medicare-covered rehab at an SNF — regardless of how many nights they spent in the hospital.
That leaves the family facing private-pay SNF rates of $12,000 to $14,000 per month in New Jersey.
The Two-Midnight Rule
The federal Two-Midnight Rule is supposed to clarify the boundary. Under this standard, a physician must certify that the patient's clinical condition reasonably requires a stay spanning at least two midnights. If it does, the stay should be classified as inpatient under Part A. If it does not, observation.
In practice, hospitals frequently reclassify patients from inpatient to observation after initial admission — sometimes days into the stay. Utilization review nurses, clinical documentation improvement specialists, and insurance auditors all influence these decisions. The clinical team may have originally admitted your parent as inpatient, but that status can change retroactively.
How You Find Out: The Medicare Change of Status Notice
When a hospital reclassifies a traditional Medicare patient from inpatient to outpatient observation, federal law requires them to deliver a Medicare Change of Status Notice (MCSN, Form CMS-10868). The notice must go out as soon as possible and no later than four hours before discharge.
The MCSN explains what changed, how it affects Medicare coverage (particularly future SNF eligibility), and the patient's right to request an expedited appeal.
If your parent has been in the hospital for more than 24 hours and you have not asked about their admission status, ask now. Do not wait for a notice. Request the status directly from the attending physician or the case manager, and get the answer in writing.

The Alexander v. Azar Appeal Right
The federal class-action settlement in Alexander v. Azar established that Medicare beneficiaries who are reclassified from inpatient to observation status have both prospective and retrospective appeal rights. Before this decision, patients caught in observation had no mechanism to challenge the classification.
Now, upon receiving the MCSN, you can request an expedited appeal through Commence Health, the designated BFCC-QIO for New Jersey (Region 2). Call 1-866-815-5440. Once the appeal is filed, the hospital is legally prohibited from billing the patient for contested services until the QIO issues a determination.
If Commence Health rules in the patient's favor, the hospital must reactivate the original inpatient admission order. That restores Part A coverage and — critically — starts counting the qualifying midnights needed for SNF rehab coverage.
Why This Matters for SNF Rehab
Medicare requires three consecutive inpatient midnights before it will cover skilled nursing facility care. Emergency room time does not count. Observation time does not count. Only time classified as inpatient under Part A qualifies.
If your parent needs rehab after a hospital stay — physical therapy after a hip fracture, for example — and their entire stay was classified as observation, Medicare will not cover a single day at the SNF. The family either pays privately or explores Medicaid coverage through New Jersey's MLTSS program, which has its own clinical and financial eligibility requirements.
Some Medicare Advantage plans waive the three-midnight requirement under certain circumstances. If your parent has an Advantage plan rather than Original Medicare, check with the plan directly about their SNF access rules.
What You Can Do Right Now
Verify your parent's admission status within the first 24 hours. Ask the attending physician directly: "Is my parent classified as inpatient or observation?" Get it documented.
If the answer is observation and you believe the clinical situation warrants inpatient care, request a physician review. If the hospital reclassifies or refuses to change, prepare to file with Commence Health the moment you receive the MCSN.
