A hospital stay and a hospital admission are not the same paper trail. Before you book a skilled nursing facility for your parent, you need to know which status the hospital assigned, because Original Medicare covers skilled nursing facility care after a qualifying inpatient hospital stay, and observation time does not count toward that stay. Medicare.gov describes the requirement for skilled nursing facility coverage, and the wording is specific enough that you should check it against your own paperwork rather than rely on memory or a neighbor's story.

Find the status line

Ask the hospital case manager, or the unit clerk if the case manager is not available, one direct question: is my parent admitted as an inpatient, or are they under observation as an outpatient? Ask for the answer in writing and ask when the status was entered. Look at every hospital paper you are handed, including the discharge packet and any bill that arrives later. The words 'observation' or 'outpatient' on any of them are the line that matters.

Ask whether the Medicare notice was given

If observation runs past 24 hours, Medicare requires the hospital to give the patient a written Medicare Outpatient Observation Notice, usually called the MOON, which explains that the patient is an outpatient and not an inpatient. Ask whether it was delivered, when, and to whom. Keep the copy. You will need it if the skilled nursing stay is denied, and it tells you the status the hospital itself recorded.

Count the inpatient days

The qualifying stay generally requires three consecutive inpatient days, counted from the formal inpatient admission and not from the time your parent arrived in the emergency department. Ask the case manager for the inpatient admission date and time as written on the inpatient order, then count the days yourself on a calendar. If the count comes up short, the bed may still be possible under a different payer, but Original Medicare may not pay the skilled nursing facility portion, and that is the point to slow down.

Read the plan rules if there is a Medicare Advantage plan

If your parent is enrolled in a Medicare Advantage plan rather than Original Medicare, the plan sets its own terms for skilled nursing facility stays. Some plans waive the three-day inpatient requirement, some require approval before admission, and most limit you to facilities in the plan's network. Call the number on the member card and ask for each of these terms in writing: the network status of the facility you are considering, whether prior approval is needed, whether the three-day rule applies, and how long the plan will cover each stay before it reviews it again.

Ask what happens on the days Medicare does not cover

Before you sign anything the facility gives you, ask which days are covered, which days are not, and who pays for each. Ask for any private-pay or financial responsibility agreement as a separate document and read it before the bed is assigned. The facility's admission packet is a contract, and the wording on the payment page controls more than the verbal promise at the front desk. If the plan of care states that your parent needs skilled services, that is a clinical determination for the physician and the discharge planner, not a billing question you can settle by phone.

If the answer is no

A denial of skilled nursing coverage comes with a written notice that states the reason and the appeal deadline. Ask for that notice and do not pay the facility on the strength of a verbal denial. The appeal process has its own clock, and the decision about whether to file it, or whether to pursue Missouri MO HealthNet coverage for nursing facility care through the Missouri Department of Social Services, is one that a lawyer or a counselor should help you weigh. Medicaid.gov describes how Medicaid nursing facility coverage works in general, but eligibility is determined by the state, and the application is separate from the hospital paperwork.

Where the free help is

Missouri SHIP counselors give free, unbiased help with Medicare coverage questions, including status disputes, plan rules, and appeal notices. Start with the list of local help on this site before you call a facility that wants a deposit today.

Your checklist before the bed is booked: the status line in writing, the MOON copy in hand, the inpatient day count on a calendar, the plan rules by phone with a note of who answered, the covered-days terms read before signing, and the denial notice requested if the answer is no. Anything beyond that, including whether the stay is medically needed or whether a coverage decision should be challenged, goes to the physician and to a qualified lawyer or counselor, not to the facility's admissions desk.
