CNA vs. Home Health Aide vs. Companion: Which In-Home Caregiver Does Your Parent Need?

The Three Roles at a Glance

When you start calling home care agencies, you'll hear three titles tossed around: Certified Nursing Assistant (CNA), Home Health Aide (HHA), and Companion. They are not interchangeable. Each one comes with a different level of training, a different legal scope of practice, and a different price tag. Choosing the wrong type can mean your parent gets care that's either insufficient or more expensive than necessary.

Here's the short version:

• CNA (Certified Nursing Assistant): State-certified through a minimum of 75 hours of training (more in many states) plus a competency exam. CNAs provide hands-on personal care: bathing, toileting, transfers, catheter care, and glucose monitoring under nurse supervision. Every CNA must appear on their state's nurse aide registry.
• HHA (Home Health Aide): Trained to a similar federal minimum of 75 hours. HHAs help with personal care, take vital signs, and assist with prescribed exercises. They can remind your parent about medications but generally cannot administer them. When working under Medicare's home health benefit, an HHA's care plan is supervised by a registered nurse.
• Companion (sometimes called a personal care attendant or homemaker): No formal certification required in most states. Companions provide social engagement, light housekeeping, meal preparation, errands, and transportation. They typically cannot perform hands-on bathing, dressing, or toileting beyond standby assistance like handing a towel.

All three can be hired through an agency or privately. But Medicare only covers CNA and HHA services when they're part of a skilled home health episode, a distinction that matters a great deal for your budget.

Training, Certification, and Scope of Practice

Understanding what each caregiver can legally do protects your parent and keeps your family out of trouble.

CNA

A CNA must complete a state-approved training program and pass a competency exam to be listed on the state nurse aide registry. In practice, many states require 100 to 180 hours of training, well above the 75-hour federal floor. CNAs can perform skilled personal care tasks (wound care assistance, catheter maintenance, blood glucose checks) as long as they have documented training and a nurse supervising the care plan.

HHA

An HHA's certification may come through federal requirements (for Medicare-certified agencies) or state-level programs. HHAs can take blood pressure, monitor chronic conditions, and coach a parent through physical therapy exercises at home. They cannot administer injectable medications or make clinical decisions. When an HHA works under Medicare home health, a registered nurse must create and periodically review the care plan.

Companion

A companion has no federally mandated training or certification. Some agencies provide their own orientation, but the bar varies widely. Because companions are non-medical caregivers, asking one to help your parent in and out of the shower or manage a catheter crosses legal and safety lines in many states. If your parent needs any hands-on hygiene help, you need a CNA or HHA.

Is Your Parent Homebound? Why This Question Shapes Everything

Families often assume Medicare will cover a home health aide for months on end. The reality is narrower. Medicare's home health benefit requires that your parent:

1. Be homebound, meaning leaving home takes considerable effort (a walker, a wheelchair, help from another person).
2. Need skilled care such as nursing, physical therapy, or occupational therapy.
3. Receive services from a Medicare-certified agency under a doctor's order.

If your parent meets those criteria, Medicare covers HHA and CNA visits as part of the skilled care episode, with no copay. But it does not cover long-term custodial care or companion services.

If your parent is not homebound, Medicare home health is off the table. Your options become private pay, a Medicaid Home and Community-Based Services (HCBS) waiver (availability and waitlists vary by state), or long-term care insurance. This is a critical decision point: determine homebound status before you start comparing agencies.

When to Choose Each Type: A Decision Framework

Companion

Best when your parent is largely independent but isolated, bored, or needs help with errands and meals. Think of a father who can shower and dress himself but shouldn't drive anymore and eats poorly when alone.

Home Health Aide

Appropriate when your parent needs daily help with bathing, dressing, or monitoring a chronic condition like diabetes or heart failure, but doesn't require complex medical procedures.

CNA

Needed when your parent requires skilled personal care under nursing oversight: post-surgical recovery, wound care, catheter management, or significant mobility limitations.

The Hybrid Scenario

Many parents don't fit neatly into one box. Imagine a mother who needs help with a morning shower (HHA territory) but also wants someone around in the afternoon for company and meal prep (companion territory). Two practical approaches:

• Split shifts: Hire an HHA for a two-hour morning block and a companion for a four-hour afternoon block. This keeps costs lower because companion rates are typically less.
• Dual-role caregivers: Some agencies employ caregivers who hold both HHA certification and companion training. Ask the agency: "Can one caregiver handle both personal care and companionship tasks in the same shift?"

Either way, ask: "Can you split shifts between different caregiver types, and how does billing work for each?"

Cost and Payment: Who Pays for What

Typical Hourly Rates

Based on the Genworth Cost of Care Survey (2025 data, the most recent available at the time of writing), national median hourly rates fall roughly in these ranges:

• Companion: $22 to $28 per hour
• HHA: $27 to $35 per hour
• CNA: $28 to $35 per hour

Expect costs to run 15 to 25% higher in major metro areas (New York, San Francisco, Boston) and somewhat lower in rural regions. Night, weekend, and holiday shifts often carry a surcharge of $2 to $5 per hour on top of the base rate. Always ask the agency for their full rate schedule, including overtime.

Coverage Sources

• Medicare Part A: Covers skilled home health (HHA/CNA) for homebound patients needing skilled care. Episodes last up to 60 days and can be renewed if the need continues. No companion coverage.
• Medicaid HCBS waivers: Cover long-term personal care (CNA/HHA) and sometimes companion services, depending on your state. Waitlists can stretch months or even years.
• Long-term care insurance: May cover all three caregiver types, depending on the policy. Check the benefit triggers (usually needing help with two or more Activities of Daily Living).
• Private pay: The fallback for everything else.

Agency Hire vs. Private Hire

Hiring through an agency costs 30 to 50% more per hour than hiring a caregiver directly. That premium buys you vetting, background checks, workers' compensation insurance, backup staffing, and payroll management.

If you hire privately, your family becomes the employer. That means handling federal and state payroll taxes, purchasing workers' compensation insurance (required in most states), running your own background checks, and managing scheduling. A caregiver injured in your parent's home without workers' comp could expose the family to significant liability. Before going this route, check your state's domestic employer labor laws.

How to Vet an Agency and Verify Credentials

Asking the right questions upfront saves you from discovering a mismatch after care has already started.

1. "Are your caregivers CNAs, HHAs, or companions? What certifications do they hold?" Some agencies label everyone "caregiver" without specifying credentials.
2. "Do you provide a registered nurse to supervise the care plan?" This is required for Medicare home health and a strong quality signal even for private-pay care.
3. "Can we request a caregiver with specific experience, such as dementia care or post-stroke recovery?"
4. "How do you verify certifications, and do you check the state CNA registry?"
5. "My parent needs help with bathing and toileting. What type of caregiver would you send, and what certifications do they hold?" This practical scenario forces the agency to be specific.

How to Independently Verify Credentials

Don't rely solely on the agency's word.

• For CNAs: Search your state's nurse aide registry online. Most state health departments offer a free lookup by name or license number. For example, search "[your state] nurse aide registry" to find the portal.
• For HHAs: Ask the caregiver or agency for a copy of their federal or state HHA certificate. Cross-reference the issuing program if you want extra assurance.
• For companions: Since no certification exists, request a copy of the background check report. If the agency won't share it, ask what screening they performed (criminal history, sex offender registry, driving record).

Common Mistakes Families Make

Hiring a companion for hands-on care. If your parent needs help getting in and out of the bathtub, a companion is not qualified and, in some states, not legally permitted to do it. This is the single most common mismatch.

Assuming every "caregiver" is certified. The word "caregiver" has no legal definition in most states. Always ask for the specific credential.

Skipping the state registry check. It takes five minutes online and confirms whether a CNA's certification is active, expired, or flagged for disciplinary action.

Expecting Medicare to cover long-term companion care. Medicare's home health benefit covers skilled, time-limited episodes. Once your parent no longer needs skilled nursing or therapy, the HHA benefit ends too. Long-term daily help requires a different payment source.

Underestimating the costs of private hire. Saving $8 to $12 per hour by hiring directly sounds appealing until you factor in employer taxes (roughly 10% of wages), workers' comp premiums, and the time you spend managing schedules and finding backup when a caregiver calls in sick.

Next Steps: Getting Started This Week

1. Assess your parent's daily needs. Use the Katz Index of Independence in Activities of Daily Living to identify where your parent needs help: bathing, dressing, toileting, transferring, continence, and feeding.
2. Determine homebound status. If your parent can leave home without considerable effort, Medicare home health likely won't apply. Plan for private pay or Medicaid.
3. Contact your local Area Agency on Aging. Visit eldercare.acl.gov or call 1-800-677-1116 for referrals to vetted agencies in your area.
4. Interview at least three agencies using the questions above. Compare not just price but caregiver qualifications, RN supervision, and backup staffing policies.
5. Verify credentials yourself. Check the state CNA registry and request documentation before care begins.
