Choosing a Medicare-Certified Home Health Agency

What does "Medicare-certified" actually guarantee?

Certification is a floor, not a recommendation. It means an agency operates under the federal Conditions of Participation and is approved to be paid by Medicare for home health services. That gives you a defined set of enforceable protections and a trained, supervised workforce. It does not mean Medicare has judged the agency to be good, and it does not rank one certified agency above another.

Medicare pays certified agencies through the Home Health Prospective Payment System — a set amount for a period of care, rather than an hourly bill to you 1Ref 1Centers for Medicare & Medicaid Services (2025).Home Health Prospective Payment System (Home Health PPS).That Medicare pays certified home health agencies through a prospective payment system — a set amount for a period of care rather than an hourly charge to the patient — which distinguishes the Medicare benefit from private-pay home care.. That one fact explains much of what you will see at intake. The agency is not selling you hours. It is delivering a plan of care inside a payment it has already been assigned.

Every certified agency cleared the same bar. Certification tells you the floor was met, never that this agency is the right one.

Two of those Conditions of Participation reach you directly. One sets out patient rights 2Ref 2Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.50 — Condition of participation: Patient rights.The enforceable federal patient rights that attach to every Medicare-certified home health agency: respectful treatment, freedom from abuse and neglect, informed consent, confidential records, notice of the agency's transfer and discharge policies, and access to a complaint process.. The other governs home health aide services, including aide training and nurse supervision 3Ref 3Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.80 — Condition of participation: Home health aide services.That home health aides working for a Medicare-certified agency must meet federal training and competency-evaluation requirements and must be supervised by a registered nurse — a standard that does not apply to a privately hired aide.. Both are federal regulation rather than agency policy, so neither is something an agency can sign away in its intake paperwork.

This page assumes home health eligibility is already settled and you are choosing among agencies. If the coverage runs through a Medicare Advantage plan rather than Original Medicare, medicare advantage home health is a separate question from the one answered here.

Where the public data on home health agencies lives

Medicare publishes quality data on every certified home health agency in the country through Care Compare, its public comparison tool. Each agency carries two separate star ratings, built from two different sources: a Quality of Patient Care rating 4Ref 4Centers for Medicare & Medicaid Services (2025).Home Health Agency Quality of Patient Care Star Rating.That Care Compare publishes a Quality of Patient Care star rating for Medicare-certified home health agencies, built from OASIS clinical assessments and Medicare claims, and that this is one of the public measures families use to compare agencies. and a Patient Survey rating 5Ref 5Centers for Medicare & Medicaid Services (2025).Patient Survey Rating for Home Health Agencies.That Care Compare publishes a separate patient-survey star rating reflecting what former patients reported about their experience with a home health agency, covering the patient-experience dimension of quality rather than the clinical one.. They are not two views of the same thing, and reading only one of them is how families get surprised.

Care Compare is free, national, and the same data whether a hospital discharge planner opens it for you or you open it yourself at the kitchen table. No agency or referral service owns it, and none can pay to sit higher in it. That is the reason to start there rather than with a list somebody handed you.

What each rating draws on

• Quality of Patient Care — built from the OASIS clinical assessments an agency completes on its own patients, combined with Medicare claims 4Ref 4Centers for Medicare & Medicaid Services (2025).Home Health Agency Quality of Patient Care Star Rating.That Care Compare publishes a Quality of Patient Care star rating for Medicare-certified home health agencies, built from OASIS clinical assessments and Medicare claims, and that this is one of the public measures families use to compare agencies..
• Patient Survey — built from a standardized survey of former patients about their experience of the care 5Ref 5Centers for Medicare & Medicaid Services (2025).Patient Survey Rating for Home Health Agencies.That Care Compare publishes a separate patient-survey star rating reflecting what former patients reported about their experience with a home health agency, covering the patient-experience dimension of quality rather than the clinical one..

Both are reported on a one-to-five scale 6Ref 6Centers for Medicare & Medicaid Services (2025).Home Health Star Ratings.The methodology behind the two home health star ratings: that both are reported on a one-to-five scale, and that an agency must have at least 20 qualifying episodes or stays to receive a rating — which is why some agencies appear unrated..

How to read the Quality of Patient Care star rating

The Quality of Patient Care rating summarizes measures drawn from the OASIS assessments an agency completes on its own patients and from Medicare claims 4Ref 4Centers for Medicare & Medicaid Services (2025).Home Health Agency Quality of Patient Care Star Rating.That Care Compare publishes a Quality of Patient Care star rating for Medicare-certified home health agencies, built from OASIS clinical assessments and Medicare claims, and that this is one of the public measures families use to compare agencies., reported on a one-to-five scale 6Ref 6Centers for Medicare & Medicaid Services (2025).Home Health Star Ratings.The methodology behind the two home health star ratings: that both are reported on a one-to-five scale, and that an agency must have at least 20 qualifying episodes or stays to receive a rating — which is why some agencies appear unrated.. It is the closest thing to a public clinical track record that exists for home health. It is also partly self-reported, since the agency records the assessments that feed it. That is worth knowing rather than a reason to discard it.

An agency needs at least 20 qualifying episodes or stays to be rated at all 6Ref 6Centers for Medicare & Medicaid Services (2025).Home Health Star Ratings.The methodology behind the two home health star ratings: that both are reported on a one-to-five scale, and that an agency must have at least 20 qualifying episodes or stays to receive a rating — which is why some agencies appear unrated..

A new agency, a small one, or one serving a thin rural catchment can show no rating for that reason alone. Unrated is not the same as poorly rated. Treating a blank as a warning quietly steers you away from small local agencies for reasons that have nothing to do with their care.

The rating is also an average across an agency's whole caseload. It answers how the agency has done in general — not how it does with wound care, or with a new oxygen setup, or with dementia. Those are questions for the intake call, and no public dataset will answer them for you.

How to read the patient survey rating

The Patient Survey rating reflects what former patients reported about their experience with the agency 5Ref 5Centers for Medicare & Medicaid Services (2025).Patient Survey Rating for Home Health Agencies.That Care Compare publishes a separate patient-survey star rating reflecting what former patients reported about their experience with a home health agency, covering the patient-experience dimension of quality rather than the clinical one.. It is a different instrument from the quality rating, and it reaches something no clinical measure does: what it was actually like to have this agency in the house. An agency can score well on clinical measures and poorly here. When the two ratings disagree, the disagreement is the useful signal, not an error to resolve.

Either rating can be blank for the same reason — too few qualifying episodes or stays to report 6Ref 6Centers for Medicare & Medicaid Services (2025).Home Health Star Ratings.The methodology behind the two home health star ratings: that both are reported on a one-to-five scale, and that an agency must have at least 20 qualifying episodes or stays to receive a rating — which is why some agencies appear unrated.. An agency with a quality rating and no survey rating is not concealing anything; it usually has not accumulated enough responses to be scored.

The survey rating is the one families tend to under-weight and then regret under-weighting. Skilled care that arrives late, or comes from someone new every visit, or from a team that does not return calls, is experienced as bad care even when the clinical measures look respectable.

The rights a certified agency already owes you

Federal regulation gives every patient of a Medicare-certified home health agency a defined set of rights: to be treated with respect, to be free from abuse and neglect, to give informed consent, to have records kept confidential, to be told the agency's transfer and discharge policies, and to use a complaint process 2Ref 2Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.50 — Condition of participation: Patient rights.The enforceable federal patient rights that attach to every Medicare-certified home health agency: respectful treatment, freedom from abuse and neglect, informed consent, confidential records, notice of the agency's transfer and discharge policies, and access to a complaint process.. These are not courtesies. They are conditions the agency's certification rests on.

The transfer and discharge policy is the right most families discover too late. Asking for it in writing at intake costs nothing, and it happens while there is no crisis and you still have a choice of agency. It is also the document worth having if the question later becomes home health discharge — whether the agency is ending care, and on what basis.

The complaint process is a right, not a favor. An agency that treats a complaint as an imposition is out of step with the regulation it is certified under.

A complaint about how an agency behaves is a different thing from a home health denial appeal, which concerns coverage rather than conduct. They travel different routes, and one does not substitute for the other.

Who actually comes to the door

The aide who arrives three mornings a week shapes daily life more than any star rating does. Under federal regulation, a home health aide working for a certified agency must meet training and competency-evaluation requirements, and must be supervised by a registered nurse 3Ref 3Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.80 — Condition of participation: Home health aide services.That home health aides working for a Medicare-certified agency must meet federal training and competency-evaluation requirements and must be supervised by a registered nurse — a standard that does not apply to a privately hired aide.. That is a real difference from a privately hired aide, who falls outside that rule entirely.

What the regulation sets is a floor for training and supervision. It says nothing about continuity — whether you see the same aide each week, or a different face each visit. Two agencies can both satisfy 42 CFR 484.80 in full and still feel completely different to live with.

So the question worth asking at intake is not whether the aides are trained. They are required to be. The question is how many of them you will meet.

Questions worth asking before you sign

The ratings narrow the field; the intake conversation decides it. Certified agencies differ most in the things no public dataset captures — how many different aides you will see, how fast a call is returned on a Saturday, whether the nurse and the therapist speak to each other. These are answerable questions, and whether an agency answers them concretely or vaguely is itself an answer.

• Staffing consistency. How many different aides is someone with this plan of care likely to see in a month?
• After-hours reach. Who picks up at eight on a Sunday evening — a clinician, or an answering service that takes a message?
• The transfer and discharge policy, in writing. You have a right to be told it 2Ref 2Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.50 — Condition of participation: Patient rights.The enforceable federal patient rights that attach to every Medicare-certified home health agency: respectful treatment, freedom from abuse and neglect, informed consent, confidential records, notice of the agency's transfer and discharge policies, and access to a complaint process.. Ask at intake, not at the end.
• The complaint route. Who receives it, and what happens after 2Ref 2Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.50 — Condition of participation: Patient rights.The enforceable federal patient rights that attach to every Medicare-certified home health agency: respectful treatment, freedom from abuse and neglect, informed consent, confidential records, notice of the agency's transfer and discharge policies, and access to a complaint process..
• Nurse supervision. How often does the RN actually visit while an aide is assigned 3Ref 3Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.80 — Condition of participation: Home health aide services.That home health aides working for a Medicare-certified agency must meet federal training and competency-evaluation requirements and must be supervised by a registered nurse — a standard that does not apply to a privately hired aide.?
• Fit for this specific need. Wound care, a new oxygen setup, and dementia are different competencies, and a star rating averages across all of them.
• Coverage of the address. An agency can be genuinely good and still cover your zip code thinly.

What the ratings cannot tell you

Star ratings describe an agency's past averages across all of its patients. They cannot tell you how it will do with your father's particular problem, and they cannot tell you who will be assigned to him. A five-star agency stretched thin across your county can serve you worse than a three-star agency with a nurse two streets away.

The gaps matter too. Agencies below the reporting threshold appear unrated 6Ref 6Centers for Medicare & Medicaid Services (2025).Home Health Star Ratings.The methodology behind the two home health star ratings: that both are reported on a one-to-five scale, and that an agency must have at least 20 qualifying episodes or stays to receive a rating — which is why some agencies appear unrated., which means the tool is systematically quieter about small agencies than large ones. And every rating describes care already delivered, to other people, under staffing that may since have turned over.

The honest use of this data is to narrow, not to decide. Certification tells you the federal floor was met 2Ref 2Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.50 — Condition of participation: Patient rights.The enforceable federal patient rights that attach to every Medicare-certified home health agency: respectful treatment, freedom from abuse and neglect, informed consent, confidential records, notice of the agency's transfer and discharge policies, and access to a complaint process.3Ref 3Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.80 — Condition of participation: Home health aide services.That home health aides working for a Medicare-certified agency must meet federal training and competency-evaluation requirements and must be supervised by a registered nurse — a standard that does not apply to a privately hired aide.. The two ratings tell you how the organization has performed on average 4Ref 4Centers for Medicare & Medicaid Services (2025).Home Health Agency Quality of Patient Care Star Rating.That Care Compare publishes a Quality of Patient Care star rating for Medicare-certified home health agencies, built from OASIS clinical assessments and Medicare claims, and that this is one of the public measures families use to compare agencies.5Ref 5Centers for Medicare & Medicaid Services (2025).Patient Survey Rating for Home Health Agencies.That Care Compare publishes a separate patient-survey star rating reflecting what former patients reported about their experience with a home health agency, covering the patient-experience dimension of quality rather than the clinical one.. The intake call tells you what it will be like. And if the first two weeks go badly, the rights you were handed at the start 2Ref 2Office of the Federal Register (Code of Federal Regulations) (2025).42 CFR 484.50 — Condition of participation: Patient rights.The enforceable federal patient rights that attach to every Medicare-certified home health agency: respectful treatment, freedom from abuse and neglect, informed consent, confidential records, notice of the agency's transfer and discharge policies, and access to a complaint process. are what you use — which is why it is worth knowing them before you need them.
