Medicare Advantage in Home Health
Medicare Advantage (MA), also called Medicare Part C, is the program in which private health plans contract with Medicare to deliver Part A and B benefits, including home health. For agencies, MA means negotiated payment rates, prior authorization requirements, and plan-specific billing rules in place of the uniform fee-for-service system. With more than half of Medicare beneficiaries enrolled in MA plans, managing these contracts well has become core to agency economics.
How MA home health differs from fee-for-service
MA plans must cover everything Original Medicare covers, including home health under the same broad eligibility framework of homebound status and skilled need. How they administer it is another matter. Plans build networks, require prior authorization before or shortly after the start of care, conduct concurrent review of continued visits, and pay according to contract rather than PDGM. A patient who looks identical on paper can produce very different revenue, workflow, and documentation demands depending on whether they carry traditional Medicare or an MA card. Agencies that treat MA episodes like FFS episodes typically discover the difference in their denial queue and their margins.
How MA plans pay for home health
Per-visit rates by discipline are the most common structure, which means agency revenue scales with authorized utilization rather than patient characteristics. Some plans pay case rates covering a defined episode, and a few use episodic models loosely patterned on PDGM. Rates typically run below what the same episode would yield under fee-for-service, and contract terms vary widely on timely filing windows, clean claim definitions, and payment timelines. Because the structures differ, comparing contracts requires converting everything to a common denominator: expected revenue and expected cost for a typical episode under each plan's real-world authorization behavior.
The operational load
MA adds administrative work at every stage. Intake must verify plan enrollment and benefits, since patients switch plans every January and sometimes mid-year. Authorization must be secured before care and renewed as visits continue, and unauthorized visits are usually unpayable. Billing must follow each plan's format and portal, and underpayments need auditing against contracted rates. Eligibility should be rechecked monthly, because an unnoticed plan switch means claims go to the wrong payer. Each of these steps costs staff time, which is why the true margin on an MA episode is lower than the rate sheet suggests.
Managing MA profitably
Agencies that make MA work treat it as a portfolio to manage:
- Know your fully loaded cost per visit by discipline, and refuse rates below it
- Score each plan on rate, authorization friction, denial rate, and days to payment
- Bring outcomes data, such as hospitalization rates, to negotiations
- Track authorization-to-visit leakage, meaning authorized visits never delivered or delivered but never authorized
- Be willing to limit or exit contracts that cannot be serviced profitably
Growth in unprofitable MA census dilutes the margin earned on the rest of the book.
Frequently asked questions
Do Medicare Advantage plans have to cover home health?
Yes. MA plans must cover all services Original Medicare covers, including home health. But they may apply utilization management such as prior authorization and concurrent review, and they pay agencies according to negotiated contracts rather than PDGM.
Does the Notice of Admission requirement apply to Medicare Advantage?
No. The NOA is a fee-for-service billing requirement. MA plans have their own notification and authorization processes defined by contract, and those timelines are often tighter than the 5-day NOA rule.
Why do MA episodes usually produce lower margins than FFS?
Two reasons compound: negotiated rates typically run below fee-for-service equivalents, and administrative costs run higher because of authorizations, plan-specific billing, and resubmissions. Agencies that do not track margin by payer often find MA growth quietly diluting overall profitability.
