Families still assume Medicare pays for nursing home care indefinitely. It doesn’t. Coverage stops at 100 days, and the daily coinsurance for days 21 through 100 just rose to $217 in 2026. That single misconception drives more billing disputes than almost anything else in skilled nursing. Here are seven more myths costing facilities real money.
By: Paul Mason, Director of Strategic Partnerships at LTCPro
For: SNF and ALF administrators, billing managers, and financial counselors who field questions from families and need billing facts, not assumptions, to back up what they tell them.
Key Takeaway: Billing misconceptions in skilled nursing don’t just confuse families. They quietly cost facilities money through disputed charges, denied claims, and missed negotiating leverage. Most of these myths trace back to one root cause: assuming a payer covers more than it actually does, or that a rule is fixed when it’s actually negotiable.

Billing in skilled nursing facilities is constantly handled by administrators, by families, and sometimes by healthcare professionals outside the LTC space. Misconceptions about Medicare, Medicaid, private insurance, and billing rules lead to real financial inefficiencies and real compliance risk. This article clears up the myths that come up most often and what to do instead.
Myth #1: Medicare Covers 100% of Skilled Nursing Facility Care
Reality: Medicare covers SNF care only under specific conditions, and only for a limited time. Part A provides up to 100 days of SNF care per benefit period, but the coverage isn’t flat across those 100 days:
- Days 1 through 20 are fully covered.
- Days 21 through 100 require a daily coinsurance. In 2026, that coinsurance is $217 per day, up from $209.50 in 2025. (CMS, 2026 Medicare Parts A & B Premiums and Deductibles)
- After 100 days, Medicare pays nothing. The patient covers all costs.
Best Practice: Educate patients and families early on these limits, before day 21 arrives as a surprise. Help them explore Medicaid or long-term care insurance before the coinsurance clock starts running.
Myth #2: Medicaid Covers All Skilled Nursing Services
Reality: Medicaid has strict eligibility rules and doesn’t cover everything. Medicaid is the primary payer for a large share of nursing facility residents, with MACPAC reporting 59% of residents covered by Medicaid. But Medicaid typically does not cover non-medical extras: private rooms without medical necessity, specialized therapies beyond the basic benefit, or personal comfort items like a personal TV.
Best Practice: Run a financial assessment at or before admission to determine Medicaid eligibility, and start the application process early. Delayed applications delay reimbursement.
Myth #3: Private Insurance Covers SNF Stays Like Medicare
Reality: Private insurance, including Medicare Advantage, doesn’t work like traditional Medicare. Coverage varies by plan, often carries higher co-pays and deductibles, and frequently requires prior authorization before a SNF stay is covered at all.
This changed meaningfully in 2026. Under CMS’s Interoperability and Prior Authorization Final Rule (CMS-0057-F), Medicare Advantage plans must now respond to standard prior authorization requests within 7 calendar days and expedited requests within 72 hours. That’s a real, enforceable timeline that didn’t exist before, and it directly affects how fast a SNF can confirm coverage before or during a stay.
Best Practice: Verify insurance benefits and secure prior authorization before providing services. Track the new 7-day and 72-hour response windows specifically, since a plan that misses them is now out of compliance, not just slow.
Myth #4: Claim Denials Are Unavoidable in SNF Billing
Reality: Most denials come from preventable errors, not unavoidable payer decisions. CMS’s own compliance data backs this up: insufficient documentation accounted for 75.5% of improper payments in SNF inpatient claims during the most recent reporting period. Incorrect coding and missing documentation made up most of the rest.
Common, preventable denial triggers include incorrect ICD-10 codes, missing physician signatures, insufficient medical necessity documentation, and late claim submissions.
Best Practice: Use claims-scrubbing software to catch errors before submission. Run regular internal audits. Train staff specifically on documentation standards, not just coding mechanics.
Myth #5: SNFs Cannot Negotiate Reimbursement Rates with Insurers
Reality: Reimbursement contracts are more negotiable than many facilities assume. Plenty of SNFs accept low rates because they believe the contract terms are fixed. They usually aren’t. Facilities that can present quality metrics and cost data have real leverage in that conversation.
Best Practice: Track patient outcomes and use that data to justify better rates. Compare your facility’s terms against market benchmarks. Revisit contracts that haven’t been renegotiated in years, since payer rates and facility performance both shift over time.
Myth #6: Billing Errors Are Not a Serious Issue
Reality: Billing mistakes can trigger real compliance violations and real financial penalties, not just a corrected claim. Common errors include upcoding or downcoding, duplicate billing, and billing for services never provided.
This isn’t theoretical. HHS-OIG opened a new, ongoing audit series targeting SNF billing under PDPM in November 2025. The first facility it reviewed was flagged for $31.2 million in improper payments. Separately, three affiliated Illinois SNFs paid $300,000 in early 2026 to resolve False Claims Act allegations tied to medically unnecessary billing, a case that started with a whistleblower lawsuit, not a routine audit.
Best Practice: Run internal audits regularly, not just when a denial forces the review. Use compliance software to flag discrepancies before they become findings. Train staff on regulatory requirements as a standing practice, not a one-time onboarding item.
Myth #7: Paper-Based Billing Is Just as Efficient as Digital Systems
Reality: Manual billing processes carry higher error rates, slower reimbursement, and higher administrative costs, and the gap is measurable at the national level. CMS reports the Medicare Fee-for-Service improper payment rate fell to 6.55% in FY2025, down from 7.66% in FY2024, the ninth consecutive year the rate has stayed below the 10% compliance threshold CMS tracks against. That steady improvement tracks closely with the broader shift toward electronic claims, scrubbing tools, and integrated EHR-to-billing workflows across the industry.
Best Practice: Move to cloud-based EHR and billing software if you haven’t already. The improvement shows up in submission accuracy, claim speed, and revenue cycle visibility, not just convenience.

FAQ
Does Medicare cover nursing home care after 100 days?
No. Medicare Part A covers up to 100 days of skilled nursing facility care per benefit period. Days 1 through 20 are fully covered. Days 21 through 100 require a daily coinsurance of $217 in 2026. After day 100, Medicare covers nothing, and the patient is responsible for all costs.
What percentage of nursing home residents rely on Medicaid?
MACPAC reports that Medicaid covers 59% of nursing facility residents nationally, making it the primary payer for the majority of long-term SNF stays. Medicaid eligibility rules are strict, and coverage doesn’t extend to every service a facility offers.
How fast do Medicare Advantage plans have to respond to prior authorization requests now?
Under CMS’s Interoperability and Prior Authorization Final Rule, effective in 2026, Medicare Advantage plans must respond to standard prior authorization requests within 7 calendar days and expedited requests within 72 hours. This is a new, enforceable requirement that didn’t exist before.
What’s the most common cause of SNF claim denials?
Insufficient documentation. CMS’s own data attributes 75.5% of improper payments in SNF inpatient claims to insufficient documentation, ahead of coding errors and missing records. Most denials are preventable with a documented second-review step before submission.
Can a skilled nursing facility actually negotiate its reimbursement rates with insurers?
Yes. Contracts are often more negotiable than facilities assume. Presenting quality metrics, patient outcome data, and market rate comparisons gives a facility real leverage, particularly with private and Medicare Advantage payers.
