Home health care is one of the most confusing areas of Medicare billing — and one where errors are common. BillKarma data shows home health billing errors affect 29% of claims, most stemming from incorrect homebound status documentation. When properly covered, Medicare pays for home health services at $0 cost to you — no deductible, no copay. But the distinction between covered skilled care and non-covered custodial care is the line that determines whether you owe nothing or thousands of dollars per month.
1. Skilled care vs. custodial care: the critical distinction
The single most important distinction in home health billing is between skilled care and custodial care. Medicare covers the first. Medicare does not cover the second on its own.
| Type | What it includes | Medicare covers? | Who provides it |
|---|---|---|---|
| Skilled nursing care | Wound care, injections, catheter care, IV therapy, complex medication management, patient education | Yes, at $0 | RN or LPN |
| Physical therapy | Mobility training, strengthening, fall prevention, post-surgical rehab | Yes, at $0 | Licensed PT |
| Occupational therapy | Activities of daily living, adaptive techniques, home safety modifications | Yes, at $0 | Licensed OT |
| Speech-language pathology | Swallowing disorders, speech and cognitive rehabilitation | Yes, at $0 | SLP |
| Medical social work | Care planning, community resource referrals (only alongside skilled care) | Yes, at $0 | Licensed MSW |
| Home health aide | Personal care: bathing, dressing, grooming (only alongside skilled care) | Yes, when skilled care also active | Home health aide |
| Custodial/personal care only | Help with bathing, dressing, meals, companionship — no skilled component | No | Home care aide |
This distinction is where most billing confusion originates. Many patients believe Medicare covers "home care" generally — it does not. A non-medical home care agency sending someone to help with bathing is providing custodial care, which Medicare does not cover unless skilled services are concurrently occurring.
2. What Medicare covers and what it doesn't
When you qualify for Medicare home health coverage, the benefit is comprehensive and cost-sharing is zero:
- Skilled nursing visits (as many as medically necessary)
- Physical, occupational, and speech therapy
- Home health aide visits (only when skilled care is also being provided)
- Medical social services
- Durable medical equipment (80% covered under Part B, 20% copay applies)
- Medical supplies used during home health visits
What Medicare does not cover under home health:
- 24-hour-a-day home care
- Meals delivered to your home
- Homemaker services (cleaning, laundry) not related to patient care
- Personal care (bathing, dressing) when no skilled care is also occurring
- Custodial nursing home-type care at home
3. The four eligibility criteria for Medicare home health
All four of the following criteria must be met for Medicare to cover home health services. Missing any one of them results in denial.
- You are homebound. Leaving home requires considerable and taxing effort. Brief, infrequent absences for medical care or other reasons (including adult day programs) do not disqualify homebound status. A physician must certify and document homebound status. This is the most frequently contested criterion — keep records of what assistance you need to leave home.
- You need skilled care. Your condition requires the skill of a licensed nurse, physical therapist, occupational therapist, or speech-language pathologist. The care must be medically necessary, not routine or maintenance-only. However, if skilled oversight is needed to ensure safe performance of a maintenance program (such as preventing decline), that can qualify as skilled.
- A physician has ordered the care. A licensed physician (or in some cases a nurse practitioner or physician assistant) must certify your eligibility and sign a plan of care. Re-certification is required every 60 days.
- The agency is Medicare-certified. The home health agency must be approved by Medicare. You can verify certification at Medicare.gov's Care Compare tool. Using a non-certified agency for services you expect Medicare to cover is a common and expensive mistake.
The 3-day hospital stay rule: Unlike skilled nursing facility benefits, Medicare home health does not require a prior 3-day inpatient hospital stay. This is a common misconception. You can qualify for Medicare home health directly, without a hospitalization, as long as the four criteria above are met.
4. How Medicare pays home health agencies (PDGM)
Since 2020, Medicare has paid home health agencies under the Patient-Driven Groupings Model (PDGM). Under PDGM, Medicare pays a fixed per-episode rate adjusted for your clinical characteristics. The agency receives one lump payment per 30-day period (two periods = one 60-day episode), rather than being paid per visit.
| PDGM factor | What it affects |
|---|---|
| Admission source (community vs. institutional) | Higher payment for patients discharged from hospital or post-acute facility |
| Clinical grouping (primary diagnosis) | Payment varies by condition type (e.g., musculoskeletal vs. behavioral health) |
| Functional impairment level | Higher payment for patients with greater functional deficits (OASIS assessment) |
| Comorbidity adjustment | Higher payment when qualifying secondary diagnoses are present |
The typical Medicare payment per 60-day episode ranges from $1,800 to $5,000 depending on these factors. For you as a patient, the key point is: your cost is $0 regardless of the episode payment amount. You are not responsible for any portion of the PDGM payment. If you are billed for covered services, that is a billing error.
5. Medicare Advantage, Medicaid, and private insurance
Medicare Advantage (Part C): MA plans must cover the same home health services as traditional Medicare but may restrict you to in-network agencies. Always verify that your home health agency is in your MA plan's network before starting care. Out-of-network agencies may result in higher cost-sharing or denied claims.
Medicaid: Traditional Medicare does not cover custodial home care, but Medicaid may — through Home and Community-Based Services (HCBS) waiver programs. These programs vary by state and often have waiting lists. Medicaid can cover personal care aides, homemaker services, and other supports that Medicare does not. Eligibility is income- and asset-based.
Long-term care insurance: Private LTC insurance typically covers home health care, including custodial care, after an elimination period (typically 30–90 days). Review your policy's definition of "benefit trigger" — most require inability to perform 2 of 6 Activities of Daily Living (ADLs) or cognitive impairment.
VA benefits: Veterans may be eligible for home-based primary care, skilled home health, and homemaker/home health aide services through the VA, independent of Medicare coverage.
6. Private-pay and out-of-pocket costs
For services Medicare does not cover (custodial care, personal aides, etc.), costs are paid out of pocket unless covered by Medicaid, LTC insurance, or VA benefits.
| Service | Typical cost | Notes |
|---|---|---|
| Home health aide (custodial) | $25–$45/hour | Varies significantly by region |
| Skilled nursing visit (private pay) | $150–$250/visit | Higher in metro areas |
| Physical therapy visit | $100–$200/visit | Agency rate vs. independent PT |
| Live-in home care aide | $200–$350/day | 24-hour availability |
| Adult day program | $75–$150/day | Medicaid often covers for eligible patients |
7. HCPCS billing codes for home health
Home health services are billed primarily using HCPCS G-codes. Seeing these on your explanation of benefits (EOB) helps verify that the services billed match what was provided.
| HCPCS code | Service |
|---|---|
| G0151 | Physical therapy visit |
| G0152 | Occupational therapy visit |
| G0153 | Speech-language pathology visit |
| G0154 | Skilled nursing visit |
| G0155 | Medical social worker visit |
| G0156 | Home health aide visit |
| G0157 | Home health agency evaluation |
The OASIS (Outcome and Assessment Information Set) assessment is required at the start of care, at recertification, and at discharge. It documents your clinical status and drives the PDGM payment calculation. The OASIS is not separately billed to you — it is part of the agency's documentation requirement.
8. Common billing errors to catch
BillKarma identifies home health billing errors in 29% of claims reviewed. The most common errors:
- Billing for visits not made: Agencies sometimes bill for a scheduled visit that was cancelled or not made. Cross-reference visit dates on your bill against your own records or a visit log.
- Wrong number of visits: The bill shows 20 visits but only 15 were made. This can happen when billing is automated and schedule changes aren't communicated to billing staff.
- Billing a skilled nursing code for custodial care: G0154 (skilled nursing) should only appear when an RN or LPN provided skilled care. If an aide helped you bathe and that visit was billed as G0154, that is upcoding.
- Incorrect homebound status documentation: The agency may have documented homebound status incorrectly, causing the claim to be denied — but then billed to you instead of correcting the documentation and resubmitting.
- Out-of-network MA billing: If you're on a Medicare Advantage plan and the agency is out-of-network, the claim may be denied and the balance billed to you. Verify network status before starting care.
- Duplicate billing across episodes: The same service billed at the end of one episode and the beginning of the next.
Frequently asked questions
Does Medicare cover home health care at no cost?
Yes — when all four eligibility criteria are met (homebound, skilled care needed, physician order, Medicare-certified agency), Medicare covers home health at $0 cost-sharing. No deductible, no copay. If you receive a bill for covered services, it is likely a billing error worth disputing.
What is the homebound requirement for Medicare home health?
Leaving home must require considerable and taxing effort. You do not have to be bedridden — brief absences for medical care, religious services, or adult day programs are allowed. Regularly driving yourself out for non-medical activities would disqualify homebound status. Proper documentation of homebound status is the most frequently disputed home health billing issue.
What is a 60-day home health episode under Medicare?
Medicare pays home health agencies in 60-day periods. The agency is recertified every 60 days if you still qualify. There is no limit on the number of episodes you can have. Your cost is $0 for each episode as long as you continue to meet eligibility criteria.
Does Medicare cover a home health aide to help me bathe and dress?
Only if you are also receiving skilled nursing or therapy services. Medicare covers home health aide visits as part of a skilled care plan — not as a standalone benefit. When skilled services end, Medicare home health aide coverage ends too, even if you still need personal care assistance.
What does private-pay home health cost without insurance?
Home health aides charge $25–$45/hour for custodial care. Skilled nursing visits average $150–$250/visit. Costs vary significantly by region. Medicaid waiver programs, long-term care insurance, and VA benefits may cover custodial services that Medicare does not.
