Original Medicare denied home health because you're not considered homebound? What the rule says and how to appeal.
Checked against the current rules on September 23, 2026.
A denial for home health because you're not considered homebound isn't the end of the story — Original Medicare has to follow specific coverage rules, and a denial that doesn't square with those rules is exactly the kind of appeal that tends to win.
Here's what the rule actually requires, what evidence usually turns a denial around, and the deadline you're working against.
What the rule requires
Coverage for home health because you're not considered homebound under Original Medicare is governed byPatient Confined to the Home andNeeds Skilled Nursing Care on an Intermittent Basis (Other than. Original Medicare generally cannot apply a stricter test than what these rules require.
Questions that decide it
Before you appeal, these are the facts that usually decide whether a denial like this holds up:
Does leaving home take considerable and taxing effort, because of illness, injury, or the need for help or a device?
Did the certifying practitioner have a face-to-face encounter with the patient related to the reason home health is needed?
When your parent does leave home, is it infrequent and for a limited purpose — a medical appointment, religious service, or similar — rather than routine?
What a winning appeal has to show
An appeal that wins usually includes:
Documentation of the specific effort required to leave home and how often absences actually occur — The homebound test is about effort and frequency, not a bare yes/no on physical capability — 42 CFR-adjacent BPM Ch. 7 §30.1.1. (You or your family provide this.)Patient Confined to the Home
The certifying practitioner's own face-to-face encounter note — The encounter has to relate to the primary reason home health is needed and has to fall within the required timing window around certification. (Your doctor's office provides this.)Needs Skilled Nursing Care on an Intermittent Basis (Other than
Your deadline to appeal
120 days from the date on the Medicare Summary Notice — 120 calendar days from when you receive it (42 CFR § 405.942(a)), with receipt presumed to be 5 days after the notice's own date unless shown otherwise.42 CFR 405.942
Your Medicare contractor itself then has its own clock to decide. 60 calendar days from when the MAC receives your timely request. Each time you submit new evidence after filing, that 60-day clock is extended by up to 14 more calendar days for that submission (42 CFR § 405.950(a), (b)(3)) — this can happen more than once.
What to ask your doctor to address
If you're asking the treating physician for a supporting letter, it should speak to:
The specific effort required for the patient to leave home, and whether a qualifying face-to-face encounter occurred.Patient Confined to the Home
How often the patient actually leaves home, and for what limited purposes, if any.Patient Confined to the Home
Questions people ask
- Can your Medicare contractor just say it's "not medically necessary" with no further explanation?
- The denial notice has to explain the basis for the decision and tell you how to appeal. If it doesn't point to a specific rule or criteria, that's itself worth raising in your appeal — you're entitled to know what standard was applied.
- What if I don't have all the evidence listed above?
- Include what you have. An appeal with partial evidence and a clear explanation of the rule still gets a real review — it doesn't need to be complete to be worth filing.
