How Fast Can Home Health Start After a Referral in Los Angeles?

Written by Jennifer Chen Wound Care Specialist, CWCN Oct 12, 2026

When someone you love is about to leave the hospital, or a doctor has just said a nurse should come to the house, the first question is usually about time. You want to know how fast can home health start, and whether there will be a gap between the last day of facility care and the first visit at home. That gap is what families worry about most, and it is a fair concern.

The honest answer is that the start date depends less on the agency and more on the referral itself. When the paperwork is complete and the patient clearly qualifies, care can begin quickly. When key pieces are missing, the start of care waits until they arrive. This guide explains what a complete referral looks like, what tends to slow things down in Los Angeles County, and what you can do to help the process move.

How fast can home health start? The short answer

HarvardCare Home Health responds to calls and referrals within one hour. Once a referral is complete and the patient appears eligible, the team may be able to start care the same day. That is a realistic possibility, not a promise. The actual start date depends on the physician order, the clinical information, insurance review, nurse or therapist availability, and the patient’s own schedule.

For many families, the more useful way to think about it is this: home health starts as soon as three things line up. The patient qualifies, the referral is complete, and a clinician can reach the home. Each of those has its own steps, and most delays come from one of them being unfinished.

Home health is planned, intermittent care. It is not an emergency service. If the patient has chest pain, trouble breathing, signs of a stroke, heavy bleeding, or any other emergency, call 911 instead of waiting for a home health visit.

What home health is, and who it is for

Before talking about speed, it helps to be clear about what is being started. Medicare-certified home health brings skilled care into the home under a plan of care signed by a physician or allowed practitioner. Services may include skilled nursing care at home, physical therapy, speech therapy, and occupational therapy, along with home health aide support when it is part of the plan.

Many people search for in-home nurse services when what they really need is this kind of skilled, physician-ordered care. The difference matters because Medicare home health has specific rules. The patient generally needs to be homebound, needs intermittent skilled nursing or therapy, and is under the care of a provider who orders and oversees the plan.

Homebound has a specific meaning. Under CMS guidance, there are two parts. First, the patient needs the help of a device such as a walker or wheelchair, special transportation, or another person to leave home because of an illness or injury, or leaving home is medically not advised. Second, the patient is normally unable to leave home, and leaving takes a considerable and taxing effort. Going to medical appointments, adult day care, or religious services, or taking an occasional short trip such as a haircut or a family event, does not by itself disqualify someone. You can read more in our guide on what qualifies as homebound for Medicare.

If the patient does not meet these criteria, home health is usually not the right service, and no amount of paperwork will speed it up. In that case, outpatient care or another type of support may be a better fit.

What makes a home health referral complete

A referral is the package of information that tells the agency who the patient is, why they need care, and who is ordering it. When people ask how fast home health can start, the most accurate answer is often: as fast as the referral becomes complete. Here is what agencies typically need.

A physician or allowed practitioner order

Home health under Medicare requires an order from a physician or another allowed practitioner, such as a nurse practitioner or physician assistant where permitted. The order should say which services are needed, such as skilled nursing for wound care or medication teaching, or physical therapy for strength and safe walking. Without an order, the agency can gather information and review eligibility, but it cannot begin the plan of care.

Face-to-face encounter documentation

Medicare requires a face-to-face encounter between the patient and a physician or allowed practitioner, related to the main reason for home health. It must happen within 90 days before the start of care or within 30 days after. For a patient leaving the hospital, the hospital visit often counts if the notes connect the condition to the need for home health and describe why the patient is homebound. Missing or vague face-to-face notes are one of the most common reasons a start date slips.

Patient demographics

The agency needs the patient’s full legal name, date of birth, home address where care will happen, phone number, and the name and number of a family member or caregiver. If the patient is staying somewhere other than their usual home after discharge, such as a relative’s apartment, that address matters for scheduling.

Insurance information

The intake team needs the patient’s Medicare number or plan card details. Some plans require prior authorization or in-network agencies, and that review can add time. If you are not sure what kind of coverage the patient has, the insurance page explains how HarvardCare Home Health reviews coverage. Medicare may cover home health when the patient is eligible and the care is medically necessary and ordered, but coverage is always confirmed case by case.

Recent clinical notes

Discharge summaries, history and physical notes, therapy evaluations, and wound descriptions help the agency understand the patient’s condition and plan the first visit. They also support the homebound and skilled-need documentation that Medicare requires.

A current medication list

An accurate medication list, including any changes made at discharge, lets the nurse prepare for medication review at the first visit. Medication changes after a hospital stay are common, and having the updated list ready avoids confusion on day one.

Doctors, discharge planners, and case managers who want a full breakdown can review our articles on home health referral requirements and the home health referral checklist for discharge planners and case managers. Families do not need to collect everything themselves, but knowing what is required helps you ask the right questions.

What usually slows down the start of home health

Most delays are not caused by a single big problem. They come from small gaps that each take a phone call or a fax to fix. Knowing the common ones helps you spot them early.

• The order is not signed yet. A doctor may agree that home health makes sense but not have signed the order before the patient leaves. Weekends and holidays can stretch this out.
• The face-to-face note does not connect the dots. If the notes do not explain why the patient needs skilled care and why leaving home is hard, the agency may need to ask the provider for an addendum.
• Insurance needs authorization. Some plans require approval before the first visit. The agency cannot control how quickly a plan responds.
• The patient is not home yet. If discharge is pushed back, or the patient goes to a skilled nursing facility first, the start of care moves with them.
• Contact information is wrong or incomplete. A disconnected phone number or a missing unit number can cost a day.
• Specialty skills are needed. Some orders, such as certain IV therapies or complex wound care, require a clinician with specific experience and the right supplies on hand.
• Supplies have not arrived. If the plan depends on equipment or dressing supplies from another vendor, the first visit may be timed around that delivery.

None of these mean something has gone wrong. They are the normal friction of moving care from one setting to another. The faster each one is identified, the faster it is resolved.

The Los Angeles County factor

Geography and daily life in LA County shape how quickly a visit can happen. A clinician driving from one side of the county to another may face heavy traffic at certain times of day, so visit windows can vary. A patient in Long Beach and a patient in Van Nuys may be scheduled around very different routes on the same day.

Housing also matters. Many patients live in apartment buildings without elevators, on hillside streets with limited parking, or in multi-story homes where the bedroom is upstairs. Giving the agency clear directions, gate codes, parking notes, and the best entrance helps the first visit start on time.

Language is another practical factor. LA County families often speak more than one language at home. If the patient or main caregiver prefers a language other than English, tell the intake team at the first call. It helps the agency plan communication for the first visit.

Finally, many caregivers work full time. If the main caregiver can only be present at certain hours, share that early. The first visit usually includes a review of the home, medications, and the plan of care, and it often goes better when the person who will help day to day can be there. Families in places like Pasadena and across the county often juggle work, children, and caregiving, and a little scheduling information up front saves time later.

What happens between the referral and the first visit

Once the agency receives a referral, several steps usually happen in a short window.

1. Acknowledgment. The intake team confirms the referral was received and checks what is included.
2. Eligibility and insurance review. The team reviews the patient’s coverage, homebound status, and skilled need based on the documents.
3. Requests for missing items. If anything is missing, such as a signed order or face-to-face notes, the team contacts the referring office or facility.
4. Contact with the patient or family. Someone calls to confirm the address, explain what to expect, and set a time for the first visit.
5. Scheduling the start of care. A nurse or therapist is assigned, based on the services ordered and the patient’s location.
6. The start of care visit. The clinician completes a full assessment, reviews medications, checks home safety, and begins the plan of care.

How families can help home health start sooner

You do not have to manage the referral yourself, but there are simple steps that often make a real difference.

• Ask about home health before discharge. Talk to the discharge planner, case manager, or hospitalist a day or two before the expected discharge, not the morning of. Ask whether home health will be ordered and which agency the referral will go to.
• Know that you can choose an agency. Patients have the right to choose a Medicare-certified home health agency. If you have a preference, tell the discharge team.
• Keep the paperwork together. Put the discharge summary, medication list, and follow-up appointments in one folder near the phone.
• Answer unknown numbers for a few days. Intake and scheduling calls may come from numbers you do not recognize.
• Share practical details. Gate codes, parking, stairs, pets, and the best times to visit all help.
• Tell the agency about changes right away. If discharge is delayed or the patient is readmitted, let the agency know so the plan can be adjusted.

Coordinating these moving parts is part of what home health does. Our care coordination at home services help keep the doctor, the family, and the care team on the same page once services begin.

Our family checklist on what to have ready before you call a home health agency puts all of this in one place.

Why the first visit timing matters after a hospital stay

The first days at home after a hospital stay can be a sensitive time. Medications may have changed, the patient may be weaker than before, and wounds, drains, or new equipment may need attention. That is why discharge teams often aim to have home health start soon after the patient gets home.

A timely start of care gives the nurse a chance to review medications against what the patient actually has at home, check for warning signs, teach the family what to watch for, and update the doctor if something does not look right. Our post-hospital discharge nurse at home page explains this kind of support in more detail.

Even so, the first visit is scheduled based on the physician’s order and the agency’s assessment of need. If the order says the visit should happen within a certain time after discharge, the agency works toward that. Visit frequency and length after the first visit are set by the physician-ordered plan of care, not by the agency alone.

What the agency cannot speed up

It is helpful to know where the limits are, so expectations stay realistic.

The agency cannot sign the physician’s order or write the face-to-face note. It cannot approve insurance authorization on behalf of a plan. It cannot start care in a home the patient has not arrived at yet. And it cannot admit a patient who does not meet the eligibility criteria for the service being ordered.

What the agency can do is respond quickly, tell you clearly what is missing, follow up with the referring office, and schedule the first visit as soon as everything is in place. Being clear about these roles saves families from feeling stuck or unsure who to call.

Frequently asked questions about how fast home health can start

Can home health start the same day as hospital discharge?

Sometimes. If the referral is complete, the patient appears eligible, insurance review is done, and a clinician is available in the area, HarvardCare Home Health may be able to start care the same day. It depends on each case, so ask the intake team what is still needed.

Who sends the referral to the home health agency?

Usually the hospital discharge planner, case manager, skilled nursing facility team, or the patient’s doctor’s office sends it. Professionals can send a referral using the form linked at the end of this article. Families can also call the agency to start the conversation, and the agency will work with the doctor on the order.

What if the doctor has not signed the order yet?

The agency can still review the patient’s information and begin checking eligibility, but care cannot start until there is a valid order. Ask the doctor’s office when the order will be signed and sent.

Does the face-to-face visit have to happen before home health starts?

Not always. Medicare allows the face-to-face encounter to happen within 90 days before or 30 days after the start of care. It must be related to the main reason for home health. A recent hospital or clinic visit often meets this requirement if the notes support it.

Why is my plan taking longer to approve home health?

Some plans require prior authorization or use specific in-network agencies. The time it takes depends on the plan. The intake team can tell you whether authorization is pending and what has been submitted.

What should I do while waiting for the first visit?

Follow the discharge instructions, keep the medication list and paperwork together, and call the doctor’s office with questions about symptoms. If the patient has an emergency, call 911. Home health is not an emergency service.
