Reduce Claim Denials in Your U.S. Long-Term Care Facility

Claim denials are not just billing problems. There are operational problems that surface in the billing office.

A denial can begin with an outdated payer assignment, an expired authorization, an incomplete Level of Care packet, a missing document, an incorrect resident-liability amount, an unworked portal message, or a handoff failure between admissions, nursing, MDS, scheduling, and billing.

By the time the denial appears, the actual mistake may be weeks old.

For skilled nursing facilities and assisted living providers, that matters because Medicaid often represents the largest share of the resident census. KFF reports that Medicaid is the primary payer for 63% of nursing-facility residents; Medicare is the primary payer for 14%, while 23% have other primary payer sources. Read KFF’s nursing-facility payer analysis.

The goal is not simply to work denials faster.

The goal is to build a process that stops the same denial from happening again.

Start with the denial chain

Most long-term-care claim denials occur when one or more elements of the revenue cycle do not match.

A payable claim requires alignment among:

• Resident eligibility for the billed date of service
• Correct payer assignment and benefit program
• Required authorization, Level of Care, or service-plan approval
• Complete documentation supporting the billed service
• Accurate claim details, including codes, units, modifiers, dates, and provider information
• Timely submission and required attachments
• Accurate payment posting and follow-up after adjudication

This is the claim-control chain.

A failure at any point can create a denial, payment hold, rejection, partial payment, recoupment, or aged AR balance.

The practical difference between a rejection and a denial

Facilities often use the terms interchangeably, but they require different responses.

A denial-management program should track all five. Focusing only on fully denied claims leaves payment leakage unresolved.

The five-stop clean-claim gate

The fastest way to reduce claim denials is to stop preventable errors before submission.

Use a required clean-claim gate for every claim, claim batch, or high-risk service category. It should be embedded in the billing system, worklist, or pre-bill review—not maintained as an optional spreadsheet that is ignored during busy periods.

Stop 1: Verify coverage for the dates billed

Confirm that the resident has active coverage for the exact service dates on the claim.

Do not rely only on eligibility confirmed at admission.

Coverage can change because of:

• Medicaid renewal or redetermination
• Medicaid managed-care assignment
• Medicare coverage ending
• Medicare Advantage plan change
• Resident transfer or discharge
• Hospitalization
• Medicaid-pending status
• Retroactive eligibility approval
• Waiver or HCBS program enrollment status
• Change in patient liability or spend-down
• Coordination-of-benefits update

Control: Verify payer eligibility at admission, during the first business week of each month, after major payer transitions, and before billing high-value or extended date spans.

Stop 2: Confirm the correct payer

A resident may be eligible for Medicaid but assigned to a Medicaid managed-care organization rather than Medicaid fee-for-service.

A claim billed to the wrong payer can create avoidable denials, rebilling work, and delayed cash.

Maintain one authoritative payer field that clearly identifies:

• Medicare fee-for-service
• Medicare Advantage plan
• Medicaid fee-for-service
• Medicaid managed-care plan
• Commercial payer
• Veterans Affairs or other program
• Private pay
• Medicaid pending
• Secondary payer or coordination-of-benefits status

Control: Require a payer-transition check when Medicare coverage ends, Medicaid begins, an MCO assignment changes, or a resident returns from hospitalization.

Stop 3: Confirm authorization and service coverage

For services that require authorization, claims should not be billed until the facility has confirmed:

• Authorization number
• Start and end date
• Approved service code
• Approved units or days
• Provider or facility authorization
• Applicable level of care
• Continued-stay or renewal requirement
• MCO-specific rule, if applicable

Authorization is not a static document. It is an expiring billing asset.

Control: Use alerts for:

• 14 days before authorization expiration
• 80% of approved units used
• 95% of approved units used
• Requests awaiting payer response
• Approvals received but not entered into the billing system
• Claims submitted outside the approved date span

Stop 4: Match documentation to the billed claim

The medical record, service record, authorization, and claim must tell the same story.

For every billed service, the file should support:

• Who received the service
• What was provided
• When it occurred
• Why it was needed
• Who delivered it, where relevant
• The related plan of care, order, assessment, or authorization
• The billed codes, units, and dates

CMS reported a Medicaid improper-payment rate of 6.12%, or $37.39 billion, for fiscal year 2025. CMS attributed 77.17% of estimated Medicaid improper payments to insufficient documentation, while noting that improper payments do not necessarily indicate fraud or abuse. Read CMS’s FY 2025 Improper Payments Fact Sheet.

That national rate is not a facility denial benchmark. It is a reminder that documentation gaps remain a major payment-integrity risk.

Control: Perform weekly documentation spot checks for new admissions, high-dollar claims, high-acuity residents, Medicaid-pending accounts, and services that historically deny.

Stop 5: Validate claim data and submission deadlines

Before submission, validate:

• Resident demographics
• Payer ID and member ID
• Provider enrollment status
• NPI and taxonomy
• Facility location
• Diagnosis support
• Service code
• Modifier
• Unit count
• Place of service
• Dates of service
• Duplicate or overlapping claim risk
• Required attachments
• Timely-filing deadline

Control: Use a focused set of high-value edits rather than dozens of low-impact edits no one reviews.

A useful pre-bill edit set includes:

• Eligibility active for service dates
• Correct payer and plan assignment
• Authorization active and sufficient
• Provider identifiers valid
• Units and dates consistent with authorization
• Duplicate and overlap detection
• Required documentation or attachment present
• Timely-filing risk flag

Find the denial patterns that cost the most

Most facilities have many denial reason codes. Only a few usually drive most of the dollar exposure.

Start by grouping denials into operational categories rather than reviewing payer codes one by one.

The purpose is not to create more reporting.

It is to convert denial data into one operational question:

Which workflow failure created this denial, and what will stop the next one?

Build a plan-by-plan MCO control sheet

Medicaid managed care creates another layer of denial risk.

An MCO may have different authorization rules, provider-network requirements, portals, appeal deadlines, documentation expectations, and claims edits from the state Medicaid fee-for-service program.

A service that does not require prior authorization under Medicaid FFS may require approval under a specific managed-care plan.

Create a control sheet for each material MCO.

Review the sheet quarterly and after any major payer notice, contract amendment, portal update, denial trend, or new service-line launch.

MCO appeal deadlines require attention

For Medicaid managed care, state and federal rules govern plan appeals and grievances. Under 42 CFR § 438.408, Medicaid managed-care plans generally must resolve standard appeals within 30 calendar days and expedited appeals within 72 hours, subject to applicable extensions.

The provider’s deadline to file an appeal is not set by a universal national number. It can depend on the state, MCO contract, provider manual, and adverse benefit determination notice.

Control: Track the actual plan-specific filing deadline stated in the denial notice. Do not assume that a federal plan-decision timeline is the same as your provider appeal-filing deadline.

Treat authorizations like expiring inventory

An authorization that expires before the service is renewed creates a direct payment risk.

This is especially important for:

• Medicaid managed-care residents
• High-acuity SNF residents
• HCBS and waiver services
• Assisted living services with approved units
• Therapy and ancillary services
• Continued-stay reviews
• Residents with frequent hospitalizations or changes in condition

A simple authorization tracker should include:

A 15-minute weekly authorization and eligibility huddle can prevent many denials before they occur. Include admissions, nursing, scheduling, MDS or clinical leadership where relevant, billing, and business-office staff.

The meeting should answer only four questions:

• Which authorizations expire in the next 14 days?
• Which residents are near their approved unit or day limit?
• Which pending approvals could affect billing or admission?
• Who owns the next action, and by when?

Use documentation that an outside reviewer can follow

Documentation does not need to be lengthy to be defensible. It needs to be complete, timely, internally consistent, and aligned with the service billed.

For SNFs, payment-relevant documentation may include MDS assessments, physician records, nursing notes, medication and treatment records, therapy documentation, care plans, Level of Care records, PASRR documentation, eligibility information, and authorization evidence.

CMS maintains the current MDS 3.0 Resident Assessment Instrument Manual, which provides official MDS assessment guidance. Facilities should rely on the current manual and applicable payer rules for MDS-related requirements.

A useful documentation alignment test

For a random sample of claims, ask:

• Do the claim dates match the resident’s census and coverage dates?
• Does the billed service match the authorization and plan of care?
• Do nursing, therapy, physician, and MDS records support the same clinical story?
• Are signatures, dates, credentials, and orders complete where required?
• Can the facility retrieve the full support file quickly?
• Is there a state- or payer-specific document required for this service?
• Would an external reviewer understand why this claim was payable without relying on a staff explanation?

If the answer is uncertain, the claim is not yet audit-ready.

Do not overlook provider enrollment

Provider enrollment, credentialing, taxonomy, and location details are quiet denial drivers because they can be missed until a payer changes an edit or rejects a batch of claims.

Maintain a central provider file that includes:

• National Provider Identifier
• Taxonomy codes
• Medicaid provider enrollment numbers
• Medicare certification and enrollment information where applicable
• Facility addresses and service locations
• Ownership details and effective dates
• Licenses and renewal dates
• Medicaid revalidation dates
• MCO contracting status
• MCO credentialing and recredentialing dates
• Rendering-provider information, where required
• Portal access ownership and contact information

Review the file at least quarterly and whenever there is a change in ownership, address, administrator, provider type, service line, or payer participation.

A claim can be clinically correct and still deny if the payer cannot match the provider, taxonomy, location, contract, or enrollment status to its records.

Work denials by dollar risk and deadline

A denial work queue should not be sorted only by the date it was received.

Prioritize by:

• Days remaining to file, correct, reconsider, or appeal
• Dollar value at risk
• Likelihood of recovery
• Root-cause recurrence
• Resident or admission impact

This helps prevent a common failure: staff resolve easy, low-dollar denials while higher-value claims approach an irreversible filing deadline.

A practical denial-triage model

Medicare FFS appeals

For Original Medicare fee-for-service claims, a party generally has 120 days from receipt of the initial determination to request a redetermination from the Medicare Administrative Contractor. If the redetermination is unfavorable, the party generally has 180 days from receipt of that decision to request reconsideration by a Qualified Independent Contractor. Read CMS guidance on Medicare redeterminations and CMS guidance on reconsiderations.

Medicaid FFS and Medicaid managed-care provider appeal deadlines differ by state and plan. Confirm the deadline in the applicable provider manual, contract, or denial notice.

Reconcile payments, not just denials

Not every revenue loss appears as a denial.

Some claims are paid at the wrong amount. Others are reduced by patient liability, offsets, recoupments, rate changes, units, or adjustment codes that are never investigated.

Build a payment-reconciliation process that compares expected and actual payment.

A denial-prevention strategy should include payment integrity. Otherwise, the facility may improve its denial rate while still missing earned revenue through partial payment or underpayment.

Make denial trends a management routine

A monthly denial meeting should last 30 minutes and produce decisions, not a long slide deck.

Suggested agenda

Do not try to fix ten processes at once.

Choose one high-volume or high-dollar denial category each month. Identify the upstream cause, change the workflow, assign an owner, and measure whether the category decreases.

The metrics that show whether the system is improving

Avoid tracking only a single blended denial rate.

Use a focused dashboard.

Set targets from your baseline, not from a generic national number.

A reasonable improvement plan may be:

• Improve first-pass acceptance over 60 to 90 days
• Reduce the top denial category over one quarter
• Reduce the number of claims approaching filing deadlines each month
• Shorten the average time to correct a rejected or denied claim
• Increase the percentage of authorizations renewed before expiration

How LTCPro helps reduce long-term care claim denials

LTCPro provides revenue-cycle, medical billing, accounts receivable, prior authorization, and back-office support for U.S. skilled nursing and assisted living facilities.

For facilities dealing with recurring Medicaid, Medicare, and managed-care denials, LTCPro can help strengthen the operational controls that determine whether a claim is clean, timely, and collectible.

Depending on your facility’s payer mix, state, systems, service lines, and available documentation, support may include:

• Eligibility and payer verification workflows
• Medicaid and MCO authorization tracking
• Claims preparation, submission, correction, and follow-up
• Denial categorization and root-cause analysis
• Payer-specific worklists and filing-deadline tracking
• Documentation and claims-readiness controls
• Medicaid AR follow-up and escalation
• Payment posting and remittance reconciliation
• Underpayment, recoupment, and adjustment review
• MCO appeals and payer correspondence support
• Reporting that connects denials to cash flow, AR, and operational ownership

LTCPro does not determine clinical eligibility, replace state Medicaid agencies or MCOs, provide legal advice, or guarantee payer approval or claim payment. Final payer, clinical, contractual, and compliance determinations remain with the appropriate authorized parties.

LTCPro’s role is to help facilities build stronger billing, authorization, documentation, AR, and payment-recovery workflows so preventable denials become less frequent and easier to resolve.

FAQ

What are the most common causes of claim denials in long-term care?

Common causes include incorrect payer selection, inactive eligibility, expired or missing authorization, incomplete documentation, patient-liability errors, provider enrollment or taxonomy problems, coding or unit mismatches, duplicate claims, discharge-and-readmission overlap issues, and missed filing deadlines.

How can a skilled nursing facility reduce Medicaid claim denials?

Use a required pre-bill clean-claim gate. Verify eligibility and payer assignment for the billed dates, confirm authorization and units, match documentation to the claim, validate provider data and claim details, and track timely-filing deadlines. Then review denial trends monthly and correct the upstream workflow causing recurring denials.

Why does documentation cause Medicaid payment problems?

A payer needs sufficient documentation to determine whether a claim meets coverage and payment requirements. CMS reported that 77.17% of estimated Medicaid improper payments in fiscal year 2025 were associated with insufficient documentation. Read CMS’s FY 2025 payment-integrity data.

What is the difference between a claim rejection and a claim denial?

A rejection occurs before the payer adjudicates the claim, often because of a format, identifier, demographic, or data error. A denial occurs after the payer adjudicates the claim and determines that payment is not due as billed. Both require follow-up, but denials often require review of coverage, authorization, policy, or documentation.

How often should we verify Medicaid eligibility?

At minimum, verify at admission, monthly, after payer changes or hospitalizations, and before billing large or high-risk date spans. Facilities with high Medicaid turnover, managed-care complexity, or frequent eligibility changes may need more frequent checks.

How should a facility track authorizations?

Track the payer, resident, service, authorization number, approved units or days, start date, end date, utilization, renewal deadline, status, and named owner. Use alerts before expiration and when units are nearing exhaustion.

What is the deadline to appeal a Medicare denial?

For Original Medicare fee-for-service, a redetermination request is generally due within 120 days of receiving the initial determination. A reconsideration request to a Qualified Independent Contractor is generally due within 180 days of receiving the redetermination decision. Read CMS’s Medicare redetermination guidance.

What denial KPIs should an SNF or ALF track?

Track first-pass acceptance, denial rate by payer and category, denial dollars, Medicaid and MCO AR days, authorization compliance, eligibility-verification completion, documentation completeness, resubmission time, appeal recovery, timely-filing dollars at risk, and underpayments recovered.
