HEALTHCARE · CLAIMS, DENIALS AND APPEALS

Recover underpayments and denials in healthcare revenue cycle

An empty denial queue is not the same as being paid correctly. A payer can adjudicate every claim, close every one of them, and still pay less than the rate in the fee schedule it signed. OutcomeCatalyst reads the contract, tests every remittance line against the rate you agreed, and drafts the demand with the contract page and the remittance line attached to each claim.

What it does

Revenue cycle intelligence, in plain terms

A referral arrives by fax and sits in a queue for three weeks. A claim is paid below the rate the payer signed and nobody notices, because it was never denied. Revenue cycle intelligence follows the patient from that first referral to the collected dollar and surfaces every point where the money stops moving.

Stop referrals leaking to competitors
Referrals stall on prior auth, unverified eligibility or simply never being contacted. Each one is ranked by value and days waiting, so the highest-value patients are worked before they go elsewhere.
Appeal the denials worth appealing
Not every denial is recoverable and not every recoverable denial is worth the effort. Denials are scored by overturn odds against your own appeal history, dollar value and the filing clock that is still running.
Catch payers paying below their own rate
An underpayment is not a denial, so it never enters a work queue. The remittance is compared to the fee schedule in the signed contract, which finds money on claims that were adjudicated and closed.
Put every site on one yardstick
Fourteen clinics with fourteen ledgers produce fourteen versions of performance. Sites are normalised so collections, no-show rate and margin per visit are comparable, and the best site becomes the model.
How it works

From referral to collected dollar, in four steps

Read-only, no migration, and no change to clinical workflow. Nothing touches care delivery.

1
Connect the clinical and financial systems
Epic or athenahealth for referrals, encounters and claims. Availity for eligibility and prior auth. Waystar for remittances. The ledger per site. Plus the fax queue, which is where referrals actually arrive.
2
Resolve the patient and the episode
A referral, an encounter, a procedure and a claim are joined into one episode, so the value of a stalled referral and the cost of a delayed authorisation can both be stated in dollars.
3
Compare what was paid to what was owed
Payer contracts are read and turned into machine-readable fee schedules, then compared line by line against the 835 remittances. The gap is the underpayment, whether or not anything was denied.
4
Work the queue before the clock runs out
Every finding carries a deadline, whether a filing limit, an appeal window or a referral going cold. The queue is ordered by dollars, odds and time remaining, with the appeal already drafted.
Why it matters

Why this matters for provider groups

Provider economics are squeezed from both ends. Reimbursement per encounter is set by contracts you have limited power to renegotiate, and cost per encounter rises with labour. That leaves collection rate and throughput as the levers actually under your control, which makes leakage the most addressable margin in the business.

Denials are the visible part and still routinely mishandled. Eligibility and registration denials are the largest single category and among the most overturnable, which means the most recoverable dollars are lost to a front-desk data problem rather than a clinical one. Every appeal has a filing deadline, so the work is time-boxed whether or not anyone is tracking it.

Underpayments are the invisible part and structurally worse. Because the claim was adjudicated and paid, it never enters a denial queue, never gets flagged, and closes clean. Detecting it requires reading a contract PDF and comparing it to a remittance file, which is not work anyone has capacity to do at claim-level volume.

Referral leakage happens before any of that. A patient referred to you who is not contacted within the first days is substantially likely to be seen elsewhere. The referral usually arrives as a fax, which means the highest-value new revenue in the practice enters through the least structured channel you have.

An underpayment is not a denial, so it never enters a work queue. The claim closes clean and the money is simply gone.
Finding it means reading the contract and the remittance together, at claim-level volume.
Agentic AI

Agentic AI in healthcare, without the hand-waving

Three words get used interchangeably by vendors and they are not the same thing. The difference decides whether a worklist actually gets shorter.

A chatbot
Answers a question you asked. No claim moves and nobody's worklist is shorter.
Automation
Fires a fixed rule the same way every time. It works until the referral arrives as a fax in a layout you have not seen, which is most of them.
An agent
Reads the evidence, checks it against the payer contract and the clinical documentation, drafts the appeal or the outreach, and hands it to a person to approve.

Most agentic AI pilots in a provider group fail for a reason that has nothing to do with the model. An agent asked whether a claim was underpaid needs the contracted rate, the remittance, the documentation and the payer's own policy. That sits in a contract PDF, a clearinghouse file, the EHR and a payer portal. The agent has no path to walk, so it guesses, and a confident guess on a denial is a wasted appeal and a wasted hour.

The agents here are deliberately narrow. Each has one job, a defined set of sources it may read, a written standard to check against, and a person who approves before anything leaves the building. That is what makes them safe to run against real money, and it is why they survive an audit. Every agent runs inside your access rules on the minimum necessary data, with an audit trail per read, and nothing reaches a patient or a payer without a person approving it.

The data layer

The data layer agentic AI actually needs

Every workflow above runs on one layer. Building it is most of the work, and it is the part nobody demos.

Entity resolution
The same patient appears differently across the EHR, the practice management system and the imaging record. The same procedure appears as a CPT code, a clinical note and a line on a remittance.
A revenue cycle ontology
Referral, encounter, procedure, claim, remittance, denial, appeal and contract term. A general-purpose model does not know that a CARC code and a contract clause have to be read together to prove an underpayment.
Provenance on every field
Each value carries the contract page, remittance line or note it came from. An appeal is only as good as the evidence you can point at.
Governance and permissions
The layer inherits your access rules and your BAA obligations. What an agent can read is what the person it works for can read, on the minimum necessary data, and every read is logged.

This is the part most vendors skip, because a layer does not demo well. It is also the reason one piece of infrastructure supports patient access, underpayment recovery and procedure economics at once, instead of three separate tools each rebuilding the same context badly.

It also compounds. The second workflow is faster to stand up than the first and the fifth is faster still, because the entities, the ontology and the connectors already exist. Most of what a new workflow needs is already sitting in the layer.

More on the same layer

What else runs on the same layer

Once the layer exists these are weeks of work rather than months, because they read the same resolved entities.

Referral leakage tracking
Referrals that never converted to an appointment, with where they went instead and how long the gap was.
Underpayment recovery
Claims paid below the contracted rate, with the contract clause and the remittance line side by side.
Denial pattern analysis
Which payer, code and provider combinations deny most often, and which appeal arguments actually win.
Prior authorisation triage
Cases likely to need authorisation flagged before scheduling, with the supporting documentation already assembled.
Provider and site economics
Contribution by provider, site and procedure, built from collected dollars rather than charges.
Charge capture gaps
Documented work that never made it onto a claim, found by reading the clinical note against the coding.

Common questions

Questions practice leaders ask first

Does this touch clinical care or the medical record?

No. Every workflow here is administrative and financial: referral logistics, eligibility, authorisation, coding support, claims and collections. Nothing suggests, alters or influences a clinical decision, and nothing writes to the record of care.

How do you handle PHI and HIPAA?

Deployment models include running entirely inside your own environment so PHI never leaves your control. Access is role-based, every read is logged, and de-identification is available where the workflow does not require identified data. This is designed for groups with existing HIPAA obligations and BAAs.

How is this different from our clearinghouse or RCM vendor?

A clearinghouse tells you a claim was rejected or paid. It does not tell you the payment was below the rate in your signed contract, because that contract is a PDF nobody machine-reads. That comparison is the gap most RCM tooling leaves open.

We already have a denial work queue. What does this add?

Ordering and reach. Denials get scored by your own overturn history rather than worked in receipt order, so the same staff hours recover more. It also covers the categories that never produce a denial at all, which is where underpayments hide.

Will this create more work for our front desk or coders?

The intent is the opposite. Findings arrive with the appeal or corrected claim already drafted from the underlying documentation, so the work shifts from investigating to reviewing and signing.

How long does implementation take?

Most engagements are live on a first workflow in four to six weeks. Denial recovery is the common starting point because the recovered dollars are verifiable against your own remittances, which makes the result easy to check.

Can this work across multiple sites with different systems?

Yes, and that is usually the reason to do it. Multi-site groups typically carry a different ledger and sometimes a different practice management system per site. Normalising them is what makes site-to-site comparison meaningful.

Who signs off on an appeal before it goes out?

Your RCM team. Every draft cites the clinical documentation, the remittance line and the contract page it relies on, so a qualified person reviews the reasoning before anything is submitted to a payer.

AI claims, denials and underpayment recovery: common questions

How do you find an underpayment nobody denied?

By reading the contract. The signed fee schedule sets a rate, usually as a percentage of Medicare by CPT, and the remittance says what actually arrived. Comparing the two per claim finds payments that are lower than agreed on claims that were adjudicated and closed, which is exactly why no denial queue ever saw them.

Where does the data come from?

From what the practice already holds. The 835 remittances, the payer agreements and their fee schedule appendices, the claims register and the denial log. The contracts are usually PDFs, often scanned, which is why they have rarely been read against the payments they govern.

Does this send appeals on its own?

No. It drafts, prices the demand per claim and attaches the evidence, and the revenue cycle lead approves before anything goes out. It also tracks the notice window on every finding, because an underpayment that falls outside the contractual window stops being recoverable no matter how good the evidence is.
