Accelerate Medicaid Payment Collections: Find the Money Your Facility Has Already Earned

A clean claim is not the same as collected revenue.

A skilled nursing facility or assisted living provider can submit claims correctly, keep denials low, and still wait too long for payment or receive less than the amount it expected.

That is why Medicaid payment collections require two controls beyond denial prevention:

• A way to monitor whether clean claims are being paid on time
• A way to identify claims that were paid, but paid incorrectly

For business office directors, CFOs, and revenue-cycle leaders, this is the difference between knowing that claims were submitted and knowing that the facility collected every dollar it earned.

Key Takeaway: Medicaid collection performance is not just a provider workflow issue. It also depends on payer payment timing, remittance accuracy, contract terms, state rules, and disciplined follow-up on paid-but-underpaid claims.

Start with the right question

Most billing teams ask:

What claims denied this month?

That is important, but incomplete.

A stronger collections review asks three questions:

• Were clean claims paid within the applicable payment timeframe?
• Were paid claims reimbursed at the correct amount?
• What payer, rate, contract, or workflow issue explains any gap?

This is especially important in long-term care because reimbursement may involve:

• Medicaid fee-for-service claims
• Medicaid managed-care claims
• Per diem or case-mix rates
• HCBS units
• Resident liability
• MCO contract rates
• Supplemental payments
• Rate adjustments
• Retroactive eligibility
• Underpayments, offsets, and recoupments

A claim can be paid without being paid correctly. A claim can be clean without being paid quickly. And a facility can have low denials while still carrying avoidable AR.

Medicaid prompt-pay requirements

Federal Medicaid regulations establish prompt-payment requirements for state Medicaid agencies.

Under 42 CFR § 447.45, state Medicaid agencies must generally:

• Pay 90% of clean claims within 30 days of receipt
• Pay 99% of clean claims within 90 days of receipt

A clean claim is generally one that can be processed without obtaining additional information from the provider or a third party. Claims under fraud or abuse investigation, or claims requiring medical-necessity review, may not meet the regulatory definition of a clean claim. (Read the federal definition and payment standard in 42 CFR § 447.45)

The American Recovery and Reinvestment Act of 2009 extended these prompt-payment standards to hospital and nursing-facility claims paid under Medicaid based on submitted claims. CMS confirmed that the 90%-within-30-days and 99%-within-90-days standards apply to qualifying nursing-facility claims received on or after June 1, 2009. (Read CMS’s prompt-pay implementation guidance)

What this means for SNFs

For qualifying Medicaid fee-for-service nursing-facility claims, the federal prompt-pay standard gives the facility a meaningful benchmark.

It does not mean every claim must be paid within 30 days.

The rule is measured as a percentage of clean claims. State systems may pay some claims later while still meeting the overall 90% and 99% standards. A claim may also be delayed for a valid reason, such as missing information, an eligibility issue, an authorization gap, a medical-necessity review, a system issue, or an active investigation.

The operational question is:

How long does our facility’s clean Medicaid FFS claims actually take to move from payer receipt to payment?

If the facility cannot answer that by claim type, payer, and service period, it cannot distinguish a billing problem from a payer-timing problem.

Interest on late Medicaid payments: verify before claiming

CMS’s 2009 implementation guidance states that interest is payable on qualifying clean nursing-facility and hospital claims that are not paid within the applicable prompt-pay timeframe. The federal guidance ties the interest calculation to the Prompt Payment Act rate. (Read CMS’s interest-payment guidance for clean non-PIP claims)

However, facilities should not assume that interest will be calculated, paid, or claimed in the same way in every state.

The process can depend on:

• State Medicaid payment procedures
• Whether the claim meets the clean-claim definition
• Fee-for-service versus managed-care status
• Provider type
• Whether the claim is paid through a periodic interim payment arrangement
• State administrative rules
• The state’s interest-payment process
• Documentation showing the receipt and payment dates
• Payer dispute or reconsideration procedures

Do not bill, offset, demand, or book expected interest without confirming the applicable state process and obtaining advice from counsel or a qualified reimbursement professional where needed.

Calculate the timing gap first

Before pursuing interest, build a payment-timing report.

For each Medicaid FFS claim, track:

Use the actual payer-receipt date where available. A claim submission date and payer receipt date may not always be the same.

Medicaid managed-care prompt payment is different

Medicaid managed-care organizations are subject to a separate prompt-payment regulation.

Under 42 CFR § 447.46, Medicaid MCOs generally must pay:

• 90% of clean claims from practitioners, provider organizations, and health facilities within 30 days of receipt
• 99% of clean claims from those providers within 90 days of receipt

The regulation also permits an MCO and provider to establish an alternative payment schedule by mutual agreement, provided it is included in the contract.

That last point matters.

An ALF or SNF should not assume the state Medicaid FFS payment cycle applies to its MCO claims. The applicable MCO contract may define:

• Payment timing
• Clean-claim standards
• Electronic submission requirements
• Claim-receipt rules
• Payment dispute process
• Reconsideration deadlines
• Interest provisions
• Alternative payment arrangements
• Provider responsibilities
• Required attachments
• Billing edits and correction process

Track FFS and MCOs separately

Do not combine all Medicaid claims into one average payment-speed metric.

Segment at least:

• Medicaid fee-for-service
• Each material Medicaid MCO
• HCBS or waiver claims, if applicable
• Supplemental or state-directed payment streams, if applicable
• Retroactive Medicaid claims
• Claims with known authorization or eligibility issues

A blended metric can hide the payer causing the delay.

For example, a facility may show an average Medicaid payment time of 29 days while one MCO regularly pays clean claims in 18 days and another takes 47 days. The blended result appears acceptable. The plan-specific cash-flow risk remains hidden.

Underpayments are paid claims with missing revenue

A denial gets attention because it appears as unpaid.

An underpayment is harder to detect because the claim appears in the payment-posting process as “paid.” The shortfall is visible only when the facility compares what it expected to receive with what the payer actually paid.

Common Medicaid underpayment causes include:

• Wrong rate effective date
• Incorrect per diem or service rate
• Incorrect MCO contract-rate setup
• Missed state rate increase
• Rate table not updated in the payer system
• Incorrect case-mix or acuity adjustment
• Missing quality or specialty add-on
• Incorrect patient liability amount
• Partial payment caused by an unexplained adjustment code
• Unit reduction
• Incorrect billing period
• Recoupment or offset against another claim
• Incorrect payer assignment
• Retroactive eligibility adjustment not processed correctly

An underpayment may be one claim. It may also be a systematic error affecting dozens or hundreds of resident days.

The expected-versus-paid test

For every material payer category, calculate:

Payment Variance = Expected Reimbursement − Actual Payment

A positive variance requires explanation.

Not every variance is recoverable. It may reflect:

• Resident liability
• A contractual reduction
• A valid recoupment
• A rate change
• A service limit
• An authorization issue
• A posting error
• A valid claim adjustment

But the facility should know which explanation applies before closing the account.

What to compare

Create a separate underpayment queue

Do not route underpayments into the same work queue as denials.

The response is different.

For an underpayment dispute, the strongest package usually includes:

• Claim number and date span
• Resident identifier
• Expected rate or payment calculation
• Actual payment amount
• Remittance advice and adjustment code
• Applicable state rate notice or MCO contract exhibit
• Authorization details, if relevant
• Resident liability calculation, if relevant
• Clear calculation of the variance
• Payer-specific dispute or reconsideration form
• Filing deadline and proof of submission

A general resubmission without rate evidence may not solve a payment variance.

The 90-day collection routine

A one-time review can identify historic leakage. It does not create a durable collections process.

Use a rolling 90-day routine.

Week 1: payment-speed review

Review:

• Claims submitted
• Claims accepted
• Claims paid
• Days from payer receipt to payment
• Clean claims paid after 30 days
• Claims pending after 30, 60, and 90 days
• Payment lag by Medicaid FFS and MCO
• Claims requiring payer follow-up

Week 2: underpayment review

Sample or review:

• High-dollar claims
• New MCO rate periods
• Recent state rate changes
• High-acuity or case-mix-adjusted claims
• Claims with unusual adjustment codes
• Claims with changes in resident liability
• Recurring service lines
• Claims involving units, add-ons, or specialized services

Week 3: dispute and escalation review

Review:

• Payment disputes filed
• Underpayments validated
• Appeals and reconsiderations pending
• Payer response deadlines
• Claims nearing filing or appeal limits
• Repeated rate or payment errors
• Escalations requiring provider relations, contract, finance, or legal support

Week 4: leadership review

Report:

• Total Medicaid payments received
• Average days to payment by payer
• Claims pending beyond internal thresholds
• Underpayments identified
• Underpayments recovered
• Recoupments or offsets
• Interest eligibility issues requiring review
• Aging Medicaid AR
• Payer-specific trends
• Open risks and assigned owners

This is a collection discipline, not just a billing report.

Three collection problems that look like internal billing issues

The following examples are illustrative and not legal, accounting, or reimbursement advice.

A clean-claim delay was hidden in the average

A facility tracked one combined “Medicaid days to payment” figure. The overall average looked reasonable.

When the data was separated, Medicaid fee-for-service and one MCO were paying quickly, while another MCO was regularly paying clean claims well beyond the facility’s normal collection expectation.

What failed: The facility used a blended payment-speed metric.

Better control: Track payment timing by payer, claim type, and service line.

A rate update was never applied correctly

A facility received a state or contract rate update and adjusted its billing expectation. Claims appeared to pay normally, but a remittance review found that the payer continued using an earlier rate table for part of the resident population.

What failed: Payment posting confirmed that claims were paid, but no one compared actual payment against the new expected rate.

Better control: Trigger expected-versus-paid reconciliation whenever a state or payer rate change becomes effective.

Underpayments were worked as denials

A business office routed all payment shortfalls to the denial team. Staff resubmitted documentation, but the payer’s issue was a rate variance rather than a coverage or documentation problem.

What failed: The facility treated a paid claim as a denial.

Better control: Use a separate underpayment queue with rate evidence, contract language, payment calculations, and payer-specific dispute tracking.

How LTCPro supports Medicaid payment collections

LTCPro supports U.S. skilled nursing and assisted living facilities with revenue-cycle, medical billing, accounts-receivable, prior-authorization, and back-office financial workflows.

For Medicaid payment collections, LTCPro can help facilities organize the operational data required to identify what is delayed, underpaid, denied, or at risk.

Depending on the facility’s state, payer mix, systems, contracts, and available documentation, support may include:

• Reviewing claims-submission and remittance timing
• Segmenting Medicaid FFS and MCO payment performance
• Identifying claims pending beyond internal collection thresholds
• Organizing expected-versus-paid reimbursement reconciliation
• Tracking payment variances, underpayments, recoupments, and offsets
• Supporting payer disputes, corrected claims, follow-up, and AR escalation
• Monitoring authorization, eligibility, resident-liability, and payer-assignment issues that delay payment
• Creating payer-specific worklists for claims, disputes, and deadlines
• Preparing finance-ready reports on payment lag, AR aging, and recoverable revenue

LTCPro does not determine whether a claim legally qualifies for interest, provide legal advice, set state Medicaid payment policy, or guarantee payer payment or underpayment recovery.

Facilities should confirm state-specific prompt-payment and interest procedures, MCO contract terms, dispute rights, and payment rules with the applicable Medicaid agency, payer, contract, reimbursement advisor, and legal counsel.

LTCPro’s role is to help the facility build the claims, payment, AR, and reconciliation workflow needed to identify and pursue revenue that may already be owed.

FAQ

How quickly must Medicaid pay clean nursing-facility claims?

Federal Medicaid prompt-payment standards generally require state Medicaid agencies to pay 90% of qualifying clean claims within 30 days and 99% within 90 days. CMS’s ARRA implementation guidance extended these standards to qualifying nursing-facility claims paid based on submitted claims. (Read CMS prompt-pay guidance)

Does every Medicaid claim have to be paid within 30 days?

No. The federal standard requires 90% of qualifying clean claims to be paid within 30 days and 99% within 90 days. Individual claims can be delayed for valid reasons, including missing information, eligibility issues, medical review, authorization issues, or payer processing exceptions.

Can a nursing facility collect interest on a late Medicaid payment?

CMS guidance provides for interest on qualifying clean nursing-facility claims not paid within the applicable timeframe. The actual state process, eligibility, calculation, and payment mechanism vary. Confirm the relevant state Medicaid rules and consult qualified counsel or reimbursement advisors before asserting an interest claim. (Read HHS guidance on interest for clean claims)

Do Medicaid managed-care plans have the same prompt-pay requirements?

MCOs are subject to separate requirements under 42 CFR § 447.46. They generally must pay 90% of clean claims from practitioners, provider organizations, and health facilities within 30 days and 99% within 90 days, unless the provider and MCO have a mutually agreed alternative payment schedule in the contract. (Read 42 CFR § 447.46)

What is a Medicaid underpayment?

A Medicaid underpayment is a claim that was paid but at less than the expected amount. The variance may result from an incorrect state or MCO rate, missing adjustment, incorrect resident liability, unit reduction, outdated rate table, offset, recoupment, or other payment issue.

How do SNFs and ALFs identify Medicaid underpayments?

Compare expected reimbursement with actual remittance payment at the resident, claim, payer, and date-of-service level. Use the applicable state rate notice, MCO contract or rate exhibit, authorization, resident-liability notice, and remittance advice to explain the difference.

Should underpayments be handled in the same queue as denials?

No. Denials and underpayments require different evidence and response paths. Denials often involve eligibility, authorization, documentation, or coding. Underpayments require rate, contract, unit, liability, adjustment-code, and payment-variance analysis.

Key takeaways

• A clean claim is not the same as collected revenue. Monitor payment timing and payment accuracy separately.
• Federal Medicaid prompt-pay rules generally require state Medicaid agencies to pay 90% of qualifying clean claims within 30 days and 99% within 90 days; CMS extended these standards to qualifying nursing-facility claims. (Read CMS guidance)
• Medicaid MCO claims follow separate prompt-payment requirements and may be subject to an alternative payment schedule specified in the provider contract. (Read 42 CFR § 447.46)
• Track payment timing by Medicaid FFS, each MCO, service line, and claim category. Do not rely on a blended average.
• Underpayments are paid claims with unexplained payment variances. They require expected-versus-paid reconciliation, not standard denial rework.
• Build a dedicated underpayment queue with contract, rate, authorization, liability, remittance, and deadline evidence.
• LTCPro can help facilities organize payment timing, remittance, AR, underpayment, denial, and payer-follow-up workflows to improve Medicaid collections.
