What this agent does
Prices the estimate, not what the patient owes
In
- 01
A procedure is scheduled, and the agent assembles the expected items from the order and the coverage on file.
- 02
Normalise item and service codes, provider identifiers and coverage details across sources.
Reason
- 03
Price each expected item against the chargemaster and the patient's benefit design.
- 04
Apply the discount, self-pay and financial-assistance rules configured for the site, never inferred.
- 05
Bind each priced item to the coverage or self-pay basis it drew on, and mark what the response leaves open.
Decide
- 06
Coverage is checked against the benefit response, and what it leaves unconfirmed is flagged before the estimate drafts.
- 07
Route every estimate to the named financial counsellor for release.
Out
- 08
Retain the priced items, the coverage basis, the counsellor's edits and the release against the account.
- 09
Execute write actions only inside the approval boundaries agreed during implementation.
Product statement
The agent assembles and prices the estimate; the financial counsellor decides what releases to the patient, and coverage stays the payer's decision, not the agent's forecast.
Example workflow
One estimate, order to release
- 1Encounter scheduledScheduling system, order entry, registration or a self-pay estimate request
- 2Items and coverage assembledOrdered items, chargemaster rates, benefit response, prior authorisations and configured discounts
- 3Estimate pricedPriced items, coverage basis, disclosures and confidence
- 4Controls appliedContent checks, timing-clock checks, AGB checks and confidence threshold
No human action required
Stages 1 to 4 run unaided, and nothing releases to the patient at any of them — the agent is drafting, and the counsellor's lane opens at the confidence gate.
Goes to the financial counsellor to release.
Adds a clearance-supervisor read first.
Counsellor release
The estimate is held with its priced items, its coverage basis and the confidence.

What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required

- Setting or overriding a chargemaster price.
- Approving a financial-assistance or charity-care application.
- Waiving or discounting a patient balance.
- Issuing the notice-and-consent form for balance billing.
Automation boundary
Agent acts unaided
- ✓Assemble expected items and price them against the chargemaster.
- ✓Check coverage and apply the patient's benefit design.
- ✓Draft the estimate in the form the rule requires.
- ✓Screen for financial assistance, and hold the estimate for the counsellor.
Any write happens inside the boundaries agreed at implementation, never ahead of release.
- Determining a payer's coverage or payment decision.
- Initiating an extraordinary collection action.
- Stating what a patient will owe as fact.
- Changes to chargemaster, coverage or discount configuration.
Example output
One estimate, annotated
Everything the agent drafts is attached to the account it was built from.

As received
Taken from the chargemaster and the benefit response on file — nothing on this side is decided by the agent.
Source facts used
- Chargemaster rate
- Payer benefit response
- Configured discount policy
Why this figure
The rate comes from the chargemaster and the benefit response on file.
What the score decides
Below the configured threshold the estimate picks up a clearance-supervisor read before.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Every scheduled encounter
From the order and coverage response
Price against chargemaster
Weigh the ordered items against the chargemaster rate, the benefit response and the configured discount policy.
An estimate is a document
The rule that priced an estimate travels with it — the record is the deliverable, not just the total.
Point the counsellor at what needs
Unconfirmed coverage and low-confidence estimates are marked, so the counsellor's read starts where the numbers are least certain.
Build an evidence trail
The estimate, the coverage it was built on and the counsellor who released it stay on the account.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.
Registration and scheduling
- Epic Prelude
- Cerner
- MEDITECH
- patient access systems
Chargemaster and pricing
- Craneware
- Change Healthcare pricing
- CDM and pricing tools
Eligibility and coverage
- Availity
- Change Healthcare
- Payer eligibility clearinghouses
Agent
Patient estimate & financial clearance
- Reads the order
- Prices the estimate
- Holds for release
Assistance and billing
- FAP and presumptive-eligibility tools
- Billing and collections
Observability & evaluation
- OpenTelemetry
- Langfuse
- Supported monitoring/evaluation sources
Integration availability depends on the client's existing systems and API access.
Agent controls
Six layers between the model and the estimate
Every control wraps the one within it. What the set does not catch is named in the map below.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether an estimate may stand
- L3
- Puts the release in a counsellor's hands
- L4 – L5
- Keep the estimate and the coverage behind it
- L6
- Reverts to the standard charge sheet when signals degrade
How Nestack evaluates it
Evaluate the estimate workflow — not only the final total.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the number the patient sees
- E1Final-output evaluationDid the priced estimate match the chargemaster rate and the coverage basis used?
- E2Step-level evaluationDid the agent use the right order, chargemaster version and coverage response?
- E3Tool evaluationDid it read and write the correct encounter, account and chargemaster field?
- E4Confidence calibrationDo low-confidence estimates actually draw more counsellor edits?
- E5Slice evaluationHow does performance change across specific service lines?
- E6Business outcomeHow many estimates needed a counsellor edit or a post-service dispute?
Floor — the outcome the health system answers for
Failure modes
Where each failure originates in the agent
Seven failure modes, placed at the stage each one starts.
Agent lifecycle
Direction of processing →
01 · Retrieval
1 mode
- GF-03
Stale chargemaster rate
A superseded chargemaster version prices the item instead of the current one.
Stage gathers
Order, chargemaster and benefit response
02 · Reasoning
2 modes
- GF-04
Quote-certain phrasing
The draft states a cost as fact instead of an estimate that may differ.
- GF-06
Ancillary marked waivable
A non-waivable ancillary charge is drafted as something a patient could consent to pay.
Stage proposes
Priced items, the coverage basis and confidence
03 · Tool / write
2 modes
- GF-02
Estimate released unchecked
A low-confidence estimate reaches the patient without the counsellor's release.
- GF-05
AGB cap bypassed on write
A FAP-eligible balance writes back above the amount generally billed.
Stage writes
Only where write access and approval policy allow it
04 · Output
1 mode
- GF-01
Required field omitted
The PPDR disclaimer or the provider's NPI and Tax ID is missing from the estimate.
Stage returns
The estimate the counsellor releases
05 · Change / Version
1 mode
- GF-07
Silent moratorium drift
A configuration change widens the estimate to imply co-provider bundling is required today.
Stage tracks
Model, prompt, chargemaster and coverage-rule changes
- Sev-1 · releases outside the boundary
- Sev-2 · a wrong estimate reaches the patient
- Sev-3 · coverage degrades, routes to review
Affected slices
A service-line rate hides where the estimate breaks
An overall estimate-variance rate can look acceptable while one encounter type accounts for most of the rework. Nestack reports the rate by slice, not only in total.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Encounters with multiple co-providers | 7.4% | 3.8× | Review | |
| Self-pay estimates for surgical cases | 5.5% | 2.9× | Review | |
| Insured estimates with unmet deductible | 3.3% | 1.7× | Watch | |
| Single-provider outpatient visits | 1.9% | 0.8× | Normal |
Bar: estimate-variance rate lift vs. the single-provider outpatient baseline · scale 0–4.0× · tick marks the 2.0× review threshold
2 of 4 slices over threshold
Evidence-linked improvement
The loop closes on the estimate, not the total
The loop shuts when the wrong estimate is a regression case, not when it has been explained. That suite is what the next estimate given is measured against.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Estimate-variance rate rises in a service-line slice.
- 02
Diagnose
The patient who planned around it is traced to the source, the rule or the workflow that missed it.
- 03
Improve
Whatever changes ships against a version, with the estimates that prompted it attached.
- 04
Verify
Nothing ships until the affected estimate cases pass a second time.
- 05
Learn
The suite grows by one case; so does the disclosure checklist.
Learn → Detect
The return edge. The next estimate runs against a suite one case longer.
Typical build scope
Twelve workstreams across six weeks
The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, estimate workflow, evaluation, integration, then production validation and handover.
