Three-Day Rule Skilled Nursing Facility Indiana: Medicare SNF Coverage Explained

Your parent is being discharged from an Indiana hospital and the doctor recommends skilled nursing facility rehabilitation. The first question the SNF will ask: did the patient have a qualifying three-day inpatient stay? If the answer is no, Medicare won't pay — and the family is looking at $250 to $350 per day out of pocket.

How the Three-Day Rule Counts

Under Medicare Part A (42 C.F.R. § 409.30), a patient must have three consecutive medically necessary inpatient midnights in an acute care hospital to qualify for Medicare-covered SNF care.

The counting rules are specific:

• Day of admission counts toward the three-day requirement
• Day of discharge does NOT count
• Emergency department hours do NOT count — the clock starts when the patient is formally admitted as an inpatient
• Observation days do NOT count — this is the trap most families fall into
• The three days must be consecutive — you can't combine two separate hospital stays

Example: If your parent is admitted as an inpatient on Monday, the three-day requirement is met at the start of Thursday. A Monday-to-Wednesday stay (two midnights) does not qualify.

What Medicare SNF Coverage Includes

Once the three-day rule is satisfied, Medicare Part A covers SNF rehabilitation under these terms:

• Days 1–20: Medicare covers 100% of the cost — zero out of pocket
• Days 21–100: Daily coinsurance of $217 (2026 rate). A Medigap policy or Medicare Advantage plan may cover this coinsurance.
• After day 100: Medicare coverage ends entirely

The patient must also enter the SNF within 30 days of hospital discharge and have a physician's order certifying the need for daily skilled nursing or therapy services.

SNF vs. Inpatient Rehab Facility: The Indiana Decision

Families often confuse skilled nursing facilities with inpatient rehabilitation facilities (IRFs). They serve different populations:

Skilled Nursing Facility (SNF): Provides skilled nursing care and therapy for patients who need medical monitoring but not intensive rehabilitation. The three-day rule applies. Stays typically run 20 to 30 days.

Inpatient Rehabilitation Facility (IRF): Provides intensive, multidisciplinary therapy — the "3-hour rule" requires patients to tolerate at least three hours of physical, occupational, or speech therapy daily, five days a week. IRF admission does NOT require a prior three-day hospital stay, but the patient must be able to handle the intensive therapy schedule.

If your parent can't tolerate three hours of daily therapy, IRF isn't an option. If the three-day rule wasn't met because of observation status, neither is Medicare-covered SNF care — leaving the family in a coverage gap.

How to Choose a Facility in Indiana

The hospital is required to provide a list of available SNFs in your area. Don't accept the first recommendation without comparison. Under CMS rules, hospitals must disclose performance metrics for recommended facilities.

Check these resources:

• Medicare's Care Compare tool — quality ratings, staffing levels, health inspection results, and recent citations for every Medicare-certified facility in Indiana
• Indiana Department of Health facility search — state licensing surveys and complaint history
• Verify the facility is in-network with your parent's PathWays for Aging managed care plan (Anthem, Humana, or UnitedHealthcare) if they're on Medicaid

Key metrics to compare: readmission rates, falls with major injury, pressure ulcer rates, antipsychotic medication usage, and staffing hours per resident day.

You have the right to choose the facility. Hospital staff may pressure you to accept an open bed quickly, but federal law protects the patient's right to select their preferred provider.

The LCAR Requirement for Medicaid Patients

If your parent is transitioning to long-term (not just rehab) SNF care under Medicaid, the LCAR process adds another requirement. Before a Medicaid-covered SNF admission, a Level of Care assessment must be completed through the Maximus AssessmentPro system, along with a PASRR Level I screening.

For active hospital inpatients transferring directly to a SNF, the hospital retains the authority to submit the LCAR data through the Maximus portal. Confirm with the discharge planner that this screening has been completed before the transfer date.

Medicare Advantage Exceptions

Many Medicare Advantage plans in Indiana waive the three-day inpatient requirement for SNF coverage. This is a significant benefit — if your parent has a Medicare Advantage plan, call the plan's member services line and ask directly: "Does this plan require a three-day inpatient stay before covering SNF rehabilitation?"

Some Medicare Advantage plans also extend the SNF benefit beyond 100 days or reduce the coinsurance for days 21-100. Check the plan's Evidence of Coverage document or call before assuming the standard Medicare terms apply.

When the Three-Day Rule Wasn't Met

If your parent's hospital stay doesn't meet the three-day requirement — usually because of observation status — your options include:

1. File an appeal with Commence Health (888-524-9900) if observation status was applied inappropriately
2. Check Medicare Advantage plan terms for a three-day waiver
3. Apply for Medicaid if financially eligible — Medicaid covers long-term SNF care without a three-day requirement
4. Negotiate with the SNF for a private-pay rate while pursuing Medicaid or other coverage
