Medicare Home Health vs Medicaid Home Care: An Operations Cheat Sheet

A patient with a recent hip replacement and an aging parent with dementia might both need help at home. The visits might happen in the same hour. From the doorway, an outside observer wouldn't be able to tell which is which.

But the agency delivering the care could not be more differently structured. One is paid by Medicare under a clinical benefit. The other is paid by Medicaid under a long-term services and supports (LTSS) benefit. The rules are different, the documentation is different, the workforce is different, and the software has to be different.

This post is the cheat sheet I wish someone had handed me years ago.

The core distinction

Medicare home health is a medical benefit. Medicaid home care is a support benefit.

Medicare pays for home health when the patient is homebound, has a skilled need, and is under a physician's plan of care. The intent is clinical — to recover from an event, manage a condition, or stabilize before requiring more intensive care. The episode is bounded.

Medicaid pays for home care when the patient cannot perform activities of daily living without assistance and meets the state's level-of-care criteria. The intent is supportive — to keep the person at home rather than in a nursing facility. The benefit is open-ended.

Different intent, different rules.

Side-by-side comparison

| Dimension | Medicare Home Health | Medicaid Home Care (HCBS) | |---|---|---| | Federal authority | CMS — Medicare Part A | CMS — Medicaid Title XIX, often via §1915(c) waivers | | Payment model | PDGM — 30-day payment periods, case-mix weighted | Fee-for-service hourly rate, prior-authorized hours | | Authorization | Physician's certification + plan of care (Form 485) | State or MCO authorizes specific hours per week/month | | Payment timing | Per period, retrospective | Per shift, retrospective with EVV | | Worker | RN, PT, OT, SLP, MSW, HHA | CNA, HHA, caregiver — sometimes family member (CDS) | | Episode length | 60-day cert period, recertified as needed | Open-ended, reauthorized periodically | | Required documentation | OASIS, plan of care, visit notes | ADL log, EVV check-in/out, care plan | | EVV required | Yes (since Jan 1, 2023, under Cures Act §12006) | Yes (since Jan 1, 2020, with state-by-state rollout) | | Quality reporting | iQIES OASIS submission, HHCAHPS | State-defined; varies | | Survey body | CMS-deemed accreditor or state agency | State Department of Health or Human Services | | Patient cost-sharing | Generally $0 if homebound + skilled need | Generally $0; some waivers have copays |

Where the operational difference shows up

The above table is the abstract version. Here is what it actually feels like to run each one.

Medicare home health

The clock starts when the referral arrives. CMS requires the SOC visit to happen within 48 hours of the physician's verbal or written order. The clinician completes a SOC OASIS at that visit, the agency builds a plan of care, and the physician signs it. Visits then happen on a frequency dictated by the plan of care — say, "3W2 2W4" (three visits a week for two weeks, then two visits a week for four weeks).

The agency lives or dies by:

  • OASIS accuracy — the clinical group, functional level, and comorbidity flags determine the case-mix weight, which determines the payment.
  • LUPA management — too few visits in the 30-day period and the payment collapses to a per-visit rate. Most agencies build their schedules to clear the LUPA threshold by design.
  • Recertification timing — missing the recert window doesn't just delay paperwork; it can fully invalidate the next cert period. We've written about this elsewhere — it's the most common preventable revenue loss in home health.
  • Survey readiness — the Conditions of Participation are detailed and surveyors will pull random charts.

Software for this world has to enforce the rules. Cert periods, OASIS time points, frequency parsing, supervisory visit cadence, plan-of-care signature workflow. If the software doesn't track them, the agency does — manually, on a spreadsheet, at 9 PM on a Sunday.

Medicaid home care

The clock starts when the authorization arrives. The state or its managed care organization (MCO) issues a prior authorization for a specific number of hours per week or per month, often tied to a specific waiver (CFC, IHSS, EVV-1915, or similar — the alphabet soup varies by state). The agency then has to fill those hours with the right caregiver, every week, indefinitely.

The agency lives or dies by:

  • Caregiver retention — open shifts are unbilled hours, and the home care turnover rate has historically run north of 60% annually.
  • EVV compliance — every shift has to be electronically verified at clock-in and clock-out, with location data, or the claim won't pay. The Cures Act made this federal in 2020; states layered their own rules on top.
  • Authorization tracking — burn through the authorized hours and you stop billing; under-utilize them and the family complains. The window is narrow.
  • ADL documentation — every shift needs a checklist of completed tasks, locked at clock-out, available to surveyors.

Software for this world has to be fast. Caregivers are clocking in from a phone in someone's driveway. ADL logs need to be tappable in twenty seconds. Shift swaps need to happen between admin and caregiver in real time, on the phone, while the client is waiting.

Why one agency rarely runs both

Some large agencies do hold both licenses. But operationally, they almost always run them as separate departments with separate management, separate scheduling, and separate software — because the daily work is so different that combining them creates more friction than scale.

Home health is a clinical operation that happens to be run on a schedule. Home care is a staffing operation that happens to deliver care.

When we sat down to design our software, we briefly considered building one product that toggled between modes. We tried it. The result was a UI that compromised on both sides. Home health users wanted more clinical depth; home care users wanted less. So we split them — same engine underneath, two completely different surfaces on top.

The takeaway

If you are choosing between Medicare home health and Medicaid home care as a line of business — or evaluating software for either — start with the payer rules and let everything else follow.

  • Medicare home health = OASIS, PDGM, cert periods, route optimization. Home Health Scheduling is built for this.
  • Medicaid home care = EVV, authorizations, ADL logs, shift fill rate. Home Care Scheduling is built for this.

The mistake we've watched agencies make repeatedly is buying software for the other vertical, then bending workflows to fit. It never works. Pick the one that matches your payer mix and let the software do the heavy lifting.

Looking at home health? Home Health Scheduling automates the cert-period and OASIS workflow.

Looking at home care? Home Care Scheduling handles authorizations, EVV, and ADL logs.
