When you or a loved one is admitted to the hospital, most people assume that Medicare or private insurance will cover the stay the same way every time (and even every day). However, there is something called “observation status” that can change how your stay is billed and covered by insurance. It has caught many families off guard, and the financial fallout can be brutal. Considering the average hospital admission can cost approximately $11,700 to over $14,000 per admission, the costs can be crippling. That said, here are five ways having an “observation status” on your bill could leave you and your family with a pile of unexpected bills.
1. Observation Status Bills Under Part B Instead of Part A
The first major problem with observation status is that it changes how Medicare bills the stay. Instead of being covered under Medicare Part A, which has a single deductible for the entire hospitalization, observation care is billed under Part B.
That means families face 20 percent coinsurance for every test, scan, medication, and service provided. These itemized charges add up quickly, especially for seniors who require multiple tests or monitoring. Many families don’t realize the difference until the bill arrives weeks later.
2. Prescription Drugs in the Hospital Aren’t Fully Covered
Another costly surprise tied to observation status is how hospitals bill prescription medications. Under inpatient status, medications are bundled into the hospital stay, but under observation, they are billed individually, often at inflated hospital prices.
Medicare Part D may not cover these drugs, leaving families responsible for the full cost. Some seniors are shocked to learn they’re being charged $20 to $40 per pill for medications they normally get for a few dollars at their pharmacy.
3. Observation Days Don’t Count Toward Skilled Nursing Eligibility
Perhaps the most financially devastating consequence of observation status is its impact on skilled nursing facility (SNF) coverage. Medicare requires a three‑day inpatient stay before it will pay for rehab or nursing home care.
Observation days do not count toward this requirement, even if the patient spent those days in a hospital bed receiving round‑the‑clock care. Families often discover this rule only after a loved one is discharged and needs rehab, leaving them with bills that can exceed $500 per day.
4. Hospitals Aren’t Required to Tell You Right Away
One of the most frustrating aspects of observation status is that hospitals don’t always explain it clearly. While Medicare requires hospitals to provide a written notice, many families receive it late in the stay or don’t fully understand what it means.
The notice often arrives when patients are tired, medicated, or overwhelmed, making it easy to miss critical details. Without clear communication, families assume they are admitted as inpatients when they are not.
5. Appeals Are Limited and Often Confusing
Even when families realize the problem, appealing the observation status is complicated. Unlike inpatient denials, observation classifications have fewer appeal options and stricter timelines.
Many families don’t know they can request a utilization review or ask the doctor to justify the inpatient status. Others don’t understand the process until after the bill arrives, when it’s too late to make changes. The confusing appeal system leaves many families stuck with charges they never expected
Families Can Protect Themselves With a Few Key Questions
The best defense against surprise bills caused by observation status is asking the right questions early. Families should ask the hospital daily whether the patient is classified as an inpatient or an observation and request written confirmation. If the classification seems incorrect, they can ask the doctor to document medical necessity for inpatient care. Keeping detailed notes and requesting a utilization review can also help. Awareness and persistence are the strongest tools families have to avoid unnecessary financial strain.
