Understanding Medicare's observation status: What it means for your hospital stay

Navigating Medicare can sometimes feel complex, especially when it comes to hospital stays. One area that often causes confusion for beneficiaries is the difference between being admitted as an "inpatient" and being placed under "observation status." While you might be staying in a hospital bed, receiving medical care, and even eating hospital food, your official status can have a major impact on your costs and subsequent care coverage.

What is observation status?

Observation status means your doctor is trying to figure out if you need to be admitted as an inpatient or if you can be treated and discharged within a relatively short period, usually less than 48 hours. During this time, you're considered an outpatient, even if you stay overnight in a hospital room. This determination is made by your doctor and the hospital, not necessarily based on how serious your condition feels to you.

Medicare Part B (medical insurance) generally covers services you receive during an observation stay, including doctor visits, tests, and some medications. However, Part A (hospital insurance) coverage, which typically covers inpatient hospital stays, does not apply. This distinction is vital for a few reasons.

The financial impact on your wallet

If you are under observation status, even for several days, all services are billed under Medicare Part B. This means you will likely pay a copayment for each service, and you may be responsible for the Part B deductible. In contrast, an inpatient stay under Medicare Part A typically involves one deductible per benefit period, covering all hospital services. The cumulative Part B copayments for an observation stay can sometimes add up to more than an inpatient deductible.

Perhaps the most significant financial consequence of observation status involves prescription drugs. Medications administered in the hospital while under observation are usually covered under Part B. However, any routine medications you were taking before your hospital visit, and which continue during your observation period, may not be covered by Medicare Part B. Instead, you might have to pay out-of-pocket or rely on your Medicare Part D prescription drug plan, which might have its own deductibles or copayments. This is a common source of unexpected costs for beneficiaries.

How it affects skilled nursing facility coverage

Another critical difference relates to coverage for a skilled nursing facility (SNF) stay. For Medicare to cover your SNF care after a hospital visit, you must have had at least a three-day inpatient hospital stay. Time spent under observation status, even if it spans multiple nights, does not count towards this three-day requirement. If you are discharged from the hospital after an observation stay and require SNF care, Medicare Part A will not cover it, leaving you responsible for the full cost unless you have other insurance.

What you can do

While the decision on your status rests with your doctor and the hospital, you have the right to ask questions. If you find yourself in the hospital, ask the care team directly whether you are admitted as an inpatient or if you are under observation status. If you are under observation, you should receive a Medicare Outpatient Observation Notice (MOON), which explains why you are an outpatient and how it affects your Medicare coverage.

Knowing your status helps you anticipate costs and plan for potential future care needs, such as a SNF stay. If you disagree with your observation status, you can discuss it with the hospital or your doctor. While changing status might not always be possible, understanding your situation empowers you to make informed decisions about your care and finances.
