From Referral to First Visit: The Home Health Intake Timeline Explained

The stretch between a referral landing and the first visit is where a home health admission is won or lost. Get it right and the clinician walks in prepared, the patient knows who is coming, and every compliance clock is met with room to spare. Get it wrong and you spend the next 60 days chasing orders, apologizing to a discharge planner, and hoping the survey sample skips that chart.

Most intake failures I've seen in home health weren't about effort. They were about people treating targets as rules and rules as targets. So this guide keeps the two apart. Where CMS sets a requirement, it's cited. Where a number is just a good internal target, it says so.

The Timeline at a Glance

Here is how a well-run intake usually flows. Only the last row is a CMS requirement. Everything above it is an agency target that exists to protect that last row.

Track your own referral-to-first-visit time as a metric. When it drifts, the table tells you which step to look at.

Step 1: Receiving the Referral

Referrals come from hospital discharge planners, physician offices, skilled nursing facilities, and sometimes the patient or a family member calling in.

That last group matters for the clock. CMS defines a valid referral as one where the agency has adequate information about the patient and has confirmed that a physician or allowed practitioner will provide the plan of care and ongoing orders. The OASIS-E2 guidance for M0104 is explicit that calls or documentation from others, such as assisted living staff or family, do not count on their own. A family member calling does not start the 48 hours. Getting a practitioner to agree to follow the patient does.

What a complete referral includes

• Demographics: name, date of birth, address, phone, emergency contact
• Insurance: Medicare number, any Medicare Advantage or secondary coverage
• Primary diagnosis and relevant history
• The ordering physician or allowed practitioner, and whether they will sign the plan of care
• Requested disciplines and any ordered frequency
• Medication list
• Special instructions: wound care, weight-bearing status, precautions
• An ordered start of care date, if the practitioner gave one

What you usually get

A name, a diagnosis and a phone number. Your intake coordinator fills in the rest. The best fix I've seen is boring: give your top referral sources a one-page checklist of what you need, and call them back within the hour when something is missing.

Step 2: Review and Triage

In the first hour, the intake coordinator should answer three questions.

When is the deadline? The initial assessment visit has three possible deadlines under 42 CFR 484.55(a)(1): within 48 hours of referral, within 48 hours of the patient's return home, or on the start of care date the physician or allowed practitioner ordered. If the patient is still in the hospital, coordinate with the discharge date. An updated referral at discharge becomes the new referral date. If the practitioner wants a later start, the order has to name a specific date, not a range. Surveyors are told that an agency must not ask the physician for a different start date just to make its own clock work. The 48-hour rule article goes deeper on this.

Can we staff it? Is the address in your service area? Do you have the right discipline available inside that window? Any red flags, like a complex wound, bariatric equipment or a safety concern?

Have we seen this patient before? Prior records, prior OASIS data and old contact notes save the clinician real time.

Step 3: Eligibility and Payer Checks

Traditional Medicare

• Confirm Medicare coverage. Either Part A or Part B can pay for home health.
• Screen for homebound status. The certifying practitioner certifies it, and the clinician confirms it clinically at the initial and comprehensive assessments. Intake is a first look, not the decision.
• Check whether the face-to-face encounter has happened or is planned. It can occur up to 90 days before the start of care or up to 30 days after it, so an encounter that hasn't happened yet is not a reason to refuse the referral.
• Run an eligibility check before the visit. It catches the problems that sink a Medicare claim later: the patient is actually enrolled in a Medicare Advantage plan, has elected hospice, or already has an open period with another agency.
• There is no prior authorization in traditional Medicare. But if you are in Illinois, Ohio, Texas, North Carolina, Florida or Oklahoma, the Review Choice Demonstration applies. CMS extended it for five years from June 1, 2024. Pre-claim review happens before the claim, not before the first visit.

Medicare Advantage

• Confirm the plan and your network status.
• Get authorization if the plan requires it. Most do. That is a plan rule, not a CMS one.

Medicaid

• Verify eligibility. It can change month to month.
• Check for managed care enrollment and any required authorization.
• Confirm how your state runs electronic visit verification. Medicaid home health services have required EVV since January 1, 2023 under the 21st Century Cures Act.

Private insurance

• Verify home health benefits, network status, visit limits and covered disciplines.
• Authorization is almost always required.

A caution about authorizations. The 48-hour requirement in 484.55 applies to every patient your agency admits, whatever the payer. There is no exception for a pending authorization. If a plan is slow, either get a start of care date ordered that gives you room, or treat the authorization as the most urgent task in the building. Waiting quietly is not an option the regulation gives you.

Step 4: Orders

A verbal order is enough to start

Medicare lets you begin care on an oral order. Under 42 CFR 409.43(d), the order has to exist before the service, it has to be put in writing, signed and dated with the date of receipt by the registered nurse or qualified therapist who took it, and it has to be countersigned by the physician or allowed practitioner before you bill. Your state and your own policy decide who may accept a verbal order and how fast it must be authenticated. There is no federal day count for the countersignature.

An evaluate-and-treat referral is fine. The evaluating clinician contacts the practitioner to approve the specific services and frequency that come out of the evaluation.

What the order has to say

An order must name the treatment, the discipline, and the frequency (409.43(b)). If a range of visits is ordered, the upper limit is treated as the ordered frequency.

The plan of care is a bigger document. 42 CFR 484.60(a) lists its required elements, including diagnoses, mental and cognitive status, types and frequency of services, prognosis, rehab potential, functional limitations, activities permitted, nutrition, medications and treatments, safety measures, risk of emergency visits and readmission, patient education, measurable goals, and advance directives. Don't confuse the order you start on with the plan of care you finish.

The face-to-face encounter

The encounter must relate to the primary reason the patient needs home health (42 CFR 424.22(a)(1)(v)). Since January 1, 2026, it can be performed by any physician, nurse practitioner, clinical nurse specialist, physician assistant, or certified nurse-midwife allowed by state law. It no longer has to be the certifying practitioner. It can happen by telehealth.

The certifying practitioner documents the encounter date on the certification. The certification and the signed plan of care have to be in place before you submit the final claim, and you have to be able to produce the supporting documentation if a reviewer asks. Chasing the encounter note early is good practice. It is not something you need before the first visit.

Step 5: Who Opens the Case

This is where agencies get the rule wrong most often, and it's a CMS rule, not a preference.

• Nursing ordered, alone or with therapy: a registered nurse must conduct the initial assessment visit and complete the comprehensive assessment. An LPN or LVN cannot.
• Therapy only, no nursing: a physical therapist or speech-language pathologist may do both.
• OT on a Medicare patient: an occupational therapist may open the case only when OT is ordered together with PT or speech-language pathology. OT alone can't establish Medicare eligibility at the start, so an OT-only Medicare referral can't be opened by the OT. Other payers may allow it.
• Assistants never open a case. A PTA or COTA can see the patient later under the plan of care, but not for the initial or comprehensive assessment.

Source: 42 CFR 484.55(a)(2) and (b)(3).

After that, the assignment is about fit:

• Specialty: wound care, cardiac, orthopedic, pediatric
• Geography: the closest qualified clinician gets you inside the window
• Caseload: don't hand a new admission to someone already drowning
• Continuity: if the patient was with you before, try to send the same clinician

When more than one discipline is ordered, most agencies have therapy do their first evaluations within the first week and hold a case conference early on. Those are good habits. CMS doesn't set a timeline for either. The ordered frequency does.

Step 6: Calling the Patient

The first phone call sets the tone for the whole episode. Cover:

• Who you are, which agency, and why you're calling
• That the patient is home and expecting services
• A specific date and time, not "sometime Tuesday"
• What to have ready: medication bottles, insurance cards, discharge paperwork
• Gate codes, apartment numbers, which door to use
• Their questions, and a reminder call the day before

And have a backup. If the assigned clinician calls out sick, know who covers before it happens.

Step 7: The First Visit and the Days After

The initial assessment visit and the comprehensive assessment are two separate requirements. Many agencies do both on the same visit, but they don't have to.

During the visit

• Confirm the patient's identity against the referral
• Assess immediate needs and confirm eligibility, including homebound status
• Review every medication in the home against the referral list. Drug regimen review is a required part of the comprehensive assessment.
• Look at the home for safety hazards
• Teach the patient and caregiver what the plan is and what to expect
• Give the required notices before care starts: the written notice of patient rights with a signed acknowledgment, the administrator's contact information, the OASIS privacy notice, and what Medicare will and won't pay for (42 CFR 484.50). Add the HIPAA notice of privacy practices, and an ABN if a service may not be covered. Consent-to-treat forms come from your state and your policy.

After the visit: the clocks that actually apply

People mix these up all the time. The OASIS has 5 days to be completed and 30 days to be transmitted. The item with a 5-day submission deadline is the Notice of Admission, and it's the one that costs money when it's late. The OASIS assessment schedule guide covers every timepoint.

Most agencies also ask for visit notes within 24 hours, ideally the same day. That's a good policy. It's not a CMS deadline.

Where Intake Breaks Down

Authorizations. Give one person ownership of authorizations. Same-day turnaround should be normal, and a slow authorization should be escalated early, because the 48-hour clock doesn't pause for it.

Incomplete referrals. Standard referral forms, a call back within the hour when something is missing, and regular feedback to referral sources about what they left out.

Scheduling delays. Assign cases as they come in, with availability, geography and caseload in front of you. Don't hold new referrals for a morning meeting.

Clinician availability. A small per-diem pool for overflow, clinicians cross-covered in neighboring territories, and capacity you can see in real time.

Key Takeaways

• The initial assessment visit is due within 48 hours of a valid referral, within 48 hours of return home, or on the ordered start of care date. It's hours, not days, and it applies to every payer.
• A registered nurse opens any case where nursing is ordered. An OT can open a Medicare case only alongside PT or speech.
• A verbal order is enough to start, as long as it's written, signed, dated and countersigned before billing.
• The face-to-face encounter can happen up to 30 days after the start of care, and since 2026 any allowed practitioner may perform it.
• The OASIS is completed within 5 days and transmitted within 30. The Notice of Admission is due in 5, and late ones cost money.
• Everything else on your intake timeline is a target you set. Keep it honest by tracking it.

Frequently asked questions

Does the start-of-care visit have to happen within 48 hours of the referral?

Not always. Under 42 CFR 484.55(a)(1), the initial assessment visit must be held within 48 hours of referral, or within 48 hours of the patient's return home, or on the start of care date the physician or allowed practitioner ordered. The clock is in hours, and it starts at a valid referral, not at the first phone call.

Who can open a home health case when nursing is not ordered?

A physical therapist or speech-language pathologist can conduct the initial assessment visit and complete the comprehensive assessment. For Medicare patients, an occupational therapist can do it only when occupational therapy is ordered together with physical therapy or speech-language pathology. When nursing is ordered, a registered nurse must do both.

Is the OASIS due within 5 days of the start of care?

The start-of-care comprehensive assessment must be completed no later than 5 calendar days after the start of care. Transmitting it to CMS is a separate clock: within 30 days of completing the assessment. The Notice of Admission is the item that must be submitted within 5 calendar days.

Can we start care on a verbal order?

Yes. Medicare allows services to begin on an oral order, as long as the order exists before the visit, is written down, signed and dated by the registered nurse or qualified therapist who received it, and is countersigned by the physician or allowed practitioner before the agency bills.

Does the face-to-face encounter have to happen before the first visit?

No. The encounter can occur up to 90 days before the start of care or within 30 days after it, and it must relate to the primary reason the patient needs home health. Since January 1, 2026, any physician, nurse practitioner, clinical nurse specialist, physician assistant or certified nurse-midwife allowed by state law can perform it, not only the certifying practitioner.
