Home Health Under Medicare Advantage: Prior Authorization

At a glance

In short, prior authorization is the plan's review before care. It is not the care itself. A strong order from the doctor, with clear notes about need, helps the review go well. Keep copies of every approval, including the dates and number of visits it covers.

What prior authorization means in plain words

Prior means before. Authorization means approval. So prior authorization means approval before care. The plan looks at the order and the medical notes. It decides if the care fits its rules for coverage. It may approve all visits, approve some visits, or deny the request.

Plans use this step to check that care is medically needed and given in the right setting. Home health is for people who need skilled care and meet homebound rules. The plan will look for proof of both in the papers it gets.

The home health agency often sends the request for you. The agency knows what forms the plan wants. But do not assume the request was sent. Ask the agency to confirm the date it was sent. Ask for the name of the person who sent it. Write both down.

Approval can be needed more than once. A first approval may cover a first set of visits. If care must go on, the agency may need to ask again. Each new request needs fresh notes that show why care is still needed. Plan ahead so care does not pause while a new review runs.

Sample situation

Helen Brooks comes home from the hospital with a wound that needs skilled nursing care. Her doctor orders home health visits. Her daughter, Carla, calls the home health agency to set up the first visit. The agency says Helen has a Medicare Advantage plan, so the plan must review and approve the care before it starts. Carla feels stressed by the wait. She wants care to start fast. The agency tells her it will send the request with the doctor's notes. Carla asks the agency to confirm the date the request was sent. She writes down the name of the person who sent it. She also checks that the agency is in the plan's network. Then she starts a simple log of each call, with the date, the name she spoke with, and what was said. When she calls for an update, she asks what is missing and who can supply it. She keeps the plan card near the phone so the plan name and member number are exact. When approval comes, Carla writes down the start date, end date, and visit count, and keeps the papers in one folder so care can start and go on without a stall.

How home health coverage works under Medicare

Home health covers skilled care at home for a health need. Skilled care can be nursing care or therapy care that needs a trained pro. The care is usually part-time, not full-day care. It is ordered by a doctor who oversees the plan of care.

Under Original Medicare, covered home health services cost $0. That fact is from ledger entry A13. Durable medical equipment is different: you pay 20% of the Medicare-approved amount, and the Part B deductible applies. That is also from A13.

In a Medicare Advantage plan, your cost for home health may follow the plan's own cost rules. Read your plan's Evidence of Coverage book. It lists the cost for home health visits, equipment, and related care for your plan. Do not assume the cost is the same as a friend's plan. Plans differ a lot.

Other Part B-type care in a plan can involve coinsurance. In Original Medicare, Part B coinsurance is usually 20% after the deductible when the provider accepts assignment, per ledger entry A16. Your Advantage plan sets its own amounts, so check the plan book for the exact cost that applies to you.

Your Part B premium still applies when you are in an Advantage plan. The standard Part B premium is $202.90/mo, per ledger entry A1, and the Part B annual deductible is $283, per ledger entry A2. Many people pay the standard premium, though some pay more based on income. Budget for the premium even when a plan advertises a low or zero extra premium of its own.

How to help an approval go smoothly

Give the agency correct plan information at the first call. Share the plan name and member number exactly as shown on the card. A wrong number can stall a request for days. Keep the card near the phone during the first week of care.

Make sure the doctor's notes match the real need. If the patient cannot leave home without great effort, the notes should say so in plain facts. If a wound needs skilled care, the notes should describe it as the clinician records it. Do not coach or exaggerate. Just make sure true facts are not left out.

For help picking an agency that handles plan rules well, read the guide to choose a home health agency using care needs and coverage. It shows how to weigh care skill and coverage skill together, which matters a lot under prior authorization.

Ask about timing. Ask how long reviews usually take for your plan. Ask what happens if care is urgent. Some plans have fast review paths for urgent needs. The agency should know which path it used for your request.

Keep a simple log. Write the date of each call, the name of the person you spoke with, and what they said. A log turns a fog of calls into a clear record. If a dispute comes later, the log is gold.

If the plan says no, or approves fewer visits

A denial is not always the end. Read the denial notice. It should give the reason and the appeal steps. Appeals have deadlines, so act fast. Ask the doctor and agency if they will support the appeal with added notes.

A partial approval is common. The plan may approve fewer visits than the doctor asked for. Ask what notes would support the rest. The agency may send a new request as care goes on and new notes are written.

While an appeal runs, ask about safety. What care is most urgent? Can family do any safe tasks until more visits are approved? Ask the care team what to watch for and when to call for help. Do not try skilled tasks on your own if you have not been trained to do them.

You also have rights to complain about care quality through other channels, apart from a payment appeal. The plan's member handbook lists how to file a grievance as well as an appeal. Keep both paths in mind: an appeal is about coverage, a grievance is about how you were treated or how care was run.

If costs across plans are a concern, the main guide to paying for care can help you place home health costs next to premiums, equipment costs, and other care you use in a year.

When home health and other care must work together

Some patients get home health and other support at the same time. Palliative care is one example. It focuses on comfort and quality of life during a serious illness, and it can run alongside treatment. The two services must share notes so visits and goals line up.

To see how the pieces fit, read the guide to coordinate home health and palliative care at home. It explains roles in plain words so each team knows what the other team does.

Each service may need its own approval from the plan. Do not assume one approval covers the other. Ask each team who sent its request. Ask each team what was approved. Keep both approvals in the same folder.

Good coordination also means one shared list of medicines, allergies, and key contacts. Give a copy to each team. Update it when anything changes. Small steps like this prevent errors when several pros visit the same home.

Changing plans and the fall enrollment window

If prior authorization fights happen again and again, you may think about a different plan for next year. Medicare Open Enrollment runs Oct 15–Dec 7 2026, and changes take effect Jan 1 2027. That window is from ledger entry B4. Use it with care, not in anger after one hard week.

Before you switch, compare how each plan treats home health. Ask about network agencies near you. Ask about approval steps. Ask about costs for visits and equipment. A plan with a lower premium can cost more in use if its rules are tight.

Free help exists for this choice. Your State Health Insurance Assistance Program, known as SHIP, gives free Medicare counseling. A counselor can compare plans with you and explain trade-offs in plain words. Bring your current plan book and a list of your doctors, agencies, and medicines.

Do not drop a plan mid-year without a clear right to do so. Most plan changes must wait for a valid enrollment window. Ask SHIP or Medicare to confirm your window before you act, so you do not lose coverage by mistake.

Diagram

Use the diagram at the kitchen table. Mark the stage you are in today. If you are in the review stage, your next job is a status call. If you are in the decision stage and the answer was no, your next job is the appeal deadline. The diagram keeps the next step plain and near.

What to do next

Use this checklist in order. Check off each step as you finish it.

Prior authorization can slow care, but it does not have to stop care. A clear doctor's order, a checked network, a confirmed request, and a written log give you the best chance of a fast, fair review.

If a review stalls, keep calling in a calm and steady way. Ask what is missing. Ask who can supply it. Ask for names and dates. Those habits protect your loved one, your budget, and your peace of mind while skilled care at home gets the approval it needs.
