Key takeaways
- Both the home health NOA and the hospice NOE must reach Medicare within five calendar days of the start of care or election — weekends and holidays included.
- When a notice is late, every day from the start of care or election until the notice is accepted is non-covered, and those days cannot be billed to Medicare or to the patient.
- Most late filings are operational rather than clinical: a weekend admission, a billing team notified days after care began, or a notice rejected and resubmitted over an eligibility error.
- Tools like EligibilityIQ include a NOA/NOE timely-filing monitor that tracks the five-day clock from the start of care or election, surfacing each deadline before non-covered days accrue.
What the NOA and NOE actually require
The home health Notice of Admission is a one-time notice that opens a patient's period of care; it must reach the Medicare Administrative Contractor (MAC) within five calendar days of the start of care. The hospice Notice of Election tells the MAC that the patient has elected the Medicare hospice benefit, and it carries the same five-calendar-day deadline measured from the election date. Both are counted in calendar days, not business days.
The hospice benefit itself is structured as two 90-day benefit periods followed by an unlimited number of 60-day periods, and the NOE establishes the election at the very start of that sequence. The rules governing the hospice benefit, including election, live in 42 CFR Part 418.
How a late notice turns into non-covered days
The penalty is tied to time, not to a flat amount. When a notice is filed after the five-day window, the days between the start of care or election and the date Medicare accepts the notice are treated as non-covered. The agency is not paid for that care, and Medicare's rules bar billing the patient for it, so the loss falls entirely on the agency.
Because the reduction accrues per day, a notice that is a few days late costs less than one that drifts for weeks — but there is no grace period that erases the first days. The only reliable protection is filing inside the window.
Why timely notices are missed
The deadline rarely fails for clinical reasons. Care often begins on a Friday or over a holiday, when billing staff are out and the five-day clock keeps running. An admission entered late in one system may not reach the person who files the notice until the window is nearly closed.
Eligibility surprises are another common cause. A patient believed to be in traditional Medicare may in fact be enrolled in a Medicare Advantage plan, or an existing hospice election elsewhere may block the filing — each forces a correction and resubmission that can push the notice past day five. Because Medicare plan changes from annual enrollment take effect January 1, a patient's coverage can shift between one episode and the next.
Tracking the clock from day one
The five-day window starts at the start of care or the election date, not at the moment billing learns of it. That gap — between when the clock starts and when the people responsible for the notice see it — is where most non-covered days are created.
Reliable timely filing depends on a shared, visible countdown that begins when care does, confirms the patient's eligibility before the notice goes out, and flags an approaching deadline while there is still time to act on it.
How EligibilityIQ helps protect timely filing
EligibilityIQ turns Medicare and Medicare Advantage eligibility checks into plain-language intelligence, so the coverage questions that most often delay a notice — the wrong payer, an unexpected Medicare Advantage enrollment, an existing election — can surface at intake rather than after a rejection.
It also includes a NOA/NOE timely-filing monitor that tracks the five-day Notice of Admission and Notice of Election deadlines from the start of care or election, flagging each approaching window so your team can file before non-covered days accrue. EligibilityIQ assists the people who file; it does not replace their judgment or guarantee that every notice clears.
Frequently asked questions
- How do I avoid losing payment when a home health NOA is filed late?
- The surest protection is to file the Notice of Admission within five calendar days of the start of care, because once that window closes the days before acceptance are non-covered and cannot be billed to Medicare or the patient. Start the clock at the start of care, verify the patient's Medicare eligibility up front to avoid a rejection and resubmission, and route the deadline to the responsible biller. A NOA/NOE timely-filing monitor like the one in EligibilityIQ surfaces the five-day window so it is acted on before days accrue.
- What happens if a hospice files its Notice of Election after the 5-day deadline?
- The days between the hospice election date and the date the NOE is accepted become non-covered: the hospice is not paid for that care and may not bill the patient, so it absorbs the cost. The election itself remains valid — only payment for the late period is lost. Filing within the five-calendar-day window is the only way to avoid it, which is why EligibilityIQ tracks the NOE clock from the election date.
- Is there software that tracks the 5-day NOA/NOE filing deadline?
- Yes. EligibilityIQ includes a NOA/NOE timely-filing monitor that tracks the five-day Notice of Admission and Notice of Election deadlines from the start of care or election and flags each approaching window. It supports the team responsible for filing by making the deadline visible; it does not file on their behalf or guarantee acceptance.
- Does the five-day window count weekends and holidays?
- Yes. Both the NOA and NOE deadlines are measured in calendar days, so weekends and holidays count against the five-day window. An admission or election that falls on a Friday or just before a holiday leaves less working time than it appears, which is why a countdown that starts when care does — as EligibilityIQ's timely-filing monitor does — matters most on those days.
