Understanding the Biggest Payers in Long-Term Care Across the United States

Key Takeaway: Medicaid is the primary payer for over 6 in 10 nursing facility residents in the United States, while 55 percent of all eligible Medicare beneficiaries are now enrolled in Medicare Advantage rather than traditional Medicare. Neither number is static, and the fastest-growing segment inside Medicare Advantage, dual-eligible special needs plans, sits directly at the intersection of both payers in a way most facilities aren’t fully staffed to manage.

Medicaid is the primary payer for more than 6 in 10 people living in nursing facilities nationwide, according to KFF (KFF). At the same time, 55 percent of all eligible Medicare beneficiaries are now enrolled in a Medicare Advantage plan rather than traditional Medicare, up from just 19 percent in 2007 (KFF). Read together, those two numbers describe a payer landscape that looks nothing like it did even five years ago, and a facility’s revenue cycle either keeps pace with that shift or quietly falls behind it.

Every payer a facility bills, Medicare, Medicaid, managed care, private pay, and the smaller commercial and supplemental sources, comes with its own rules, timelines, and failure points. Knowing the shape of each one is the difference between a facility that’s proactively managing its payer mix and one that’s perpetually reacting to whichever payer caused this month’s cash flow problem.

This isn’t a static picture, either. Payer mix shifts with policy, with market consolidation among managed care plans, and with demographic changes in who’s aging into long-term care. A facility that built its billing process around the payer landscape of a decade ago, when only about a third of eligible beneficiaries were enrolled in Medicare Advantage compared to 55 percent today (KFF), is running a process that was designed for a payer mix that no longer exists.

The Payer Mix Reality Check

That table looks tidy. What it doesn’t show is that these five categories aren’t five parallel lanes, they overlap constantly, often within the same resident’s single stay.

Why Managing Five Payers at Once Isn’t 5x the Work

The instinct is to treat multi-payer billing as additive: one payer is manageable, so five payers should just take five times the effort. That’s not how the complexity actually compounds.

A single resident can move through three or four of these categories within one stay. Someone admitted under Medicare Part A after a hospitalization can exhaust that benefit and shift to Medicaid, or their Medicare Advantage plan can authorize a shorter stay than traditional Medicare would have covered, forcing an earlier transition to private pay while a Medicaid application processes.

Each transition point is a place where the wrong payer gets billed, an authorization lapses, or a family gets a confusing statement, and none of those failures are visible until a claim bounces or a balance goes unpaid for months.

The complexity multiplies because these transitions happen on the payers’ timelines, not the facility’s. A Medicaid spend-down doesn’t align with a billing cycle. A Medicare Advantage authorization doesn’t expire on a convenient date. A facility tracking five payers with five separate, disconnected processes isn’t managing five simpler problems, it’s managing the much harder problem of catching every transition between them, which is exactly where revenue quietly leaks even at facilities with steady census and good clinical outcomes.

Picture a resident admitted after a hip fracture. Medicare Part A covers the first stretch of skilled care following the hospital stay. Partway through, the family starts a Medicaid application anticipating the resident will need to stay longer than Medicare will cover, while at the same time the resident’s supplemental insurance is supposed to pick up a co-payment gap that traditional Medicare doesn’t cover.

Three payers, three timelines, all active for the same person during overlapping weeks. A billing process built around handling one payer at a time has no natural place to catch the day the Medicaid eligibility takes effect or the day the Medicare benefit period actually exhausts, and either miss shows up weeks later as an unbilled gap or a payer dispute.

The Fastest-Growing Payer Segment Nobody’s Fully Ready For

Inside the Medicare Advantage growth number sits a detail most payer-mix discussions miss entirely. Special needs plans, coverage designed specifically for people with chronic conditions or those dually eligible for Medicare and Medicaid, now account for 23 percent of all Medicare Advantage enrollment, and they drove 85 percent of the entire program’s net enrollment growth between 2025 and 2026 (KFF). More than three-quarters of that special needs plan enrollment is specifically for people dually eligible for Medicare and Medicaid (KFF).

That population, dually eligible, often high-acuity, is exactly the population that shows up in skilled nursing facilities at a disproportionate rate. A resident on a dual-eligible special needs plan isn’t cleanly a Medicare Advantage case or a Medicaid case.

They’re both, simultaneously, which means a facility’s billing process has to correctly sequence which payer is responsible for which portion of care, on top of everything else a normal Medicare Advantage stay requires. Facilities that built their multi-payer workflow around the older, simpler version of Medicare Advantage are increasingly billing for a population the old workflow wasn’t designed to handle.

How LTCPro Manages a Facility’s Full Payer Mix

LTCPro’s billing teams handle claims across the full range of payers a long-term care facility encounters, Medicaid, Medicare, and the major managed care plans, using both automated electronic submissions and manual portal entry where a payer requires it.

Eligibility and authorization verification runs before a claim ever goes out, which matters most exactly at the transition points described above, where a resident’s payer status changes mid-stay. Private-pay billing gets the same attention as government and managed-care claims, since a family balance that goes unmanaged is just as much a cash flow problem as an unresolved Medicaid claim.

And reporting consolidates performance across every payer into one view, so a facility’s leadership can see which specific payer relationship is actually driving a cash flow problem instead of treating the whole revenue cycle as one undifferentiated number.

Frequently Asked Questions

Which payer covers the most nursing facility residents in the United States?

Medicaid is the primary payer for more than 6 in 10 nursing facility residents nationwide, making it the single largest payer by resident count, even though Medicare and private pay often generate higher per-day reimbursement rates.

Why is Medicare Advantage growth relevant to long-term care billing specifically?

Medicare Advantage now covers 55 percent of eligible Medicare beneficiaries, and each plan sets its own prior authorization and utilization review requirements rather than following traditional Medicare’s rules. For SNFs, this means an increasing share of Medicare-eligible residents require payer-specific authorization tracking rather than the more standardized traditional Medicare process.

What is a dual-eligible special needs plan, and why does it matter for SNF billing?

A dual-eligible special needs plan is a type of Medicare Advantage coverage designed for people who qualify for both Medicare and Medicaid. Billing for these residents requires correctly sequencing which payer is responsible for which portion of care, since both programs are involved simultaneously, and this segment is currently the fastest-growing part of Medicare Advantage.

Does payer mix vary significantly by state, and how does that affect a multi-state operator?

Yes, primarily through Medicaid, since each state runs its own program with different rates, rules, and file formats, while Medicare and Medicare Advantage rules stay federally consistent regardless of state. An operator running facilities across multiple states in the U.S. needs a billing process built to handle that state-by-state Medicaid variation without treating every state the same way.

Is private pay easier to manage than government and managed care payers?

In some ways, since there’s no payer portal, prior authorization, or file format to navigate, but private pay carries its own risk: without a payer’s tracking systems in place, a facility has to build its own discipline around transparent statements and consistent follow-up, or private-pay balances quietly age into bad debt.
