What Happens When an AI Agent Can't Get an Answer From a Payer?
TL;DR
- Every AI payer-calling program hits calls that end without an answer: closed lines, IVR dead ends, long holds that drop, representatives who won't release information, and payers that restrict automated callers.
- What matters is what happens to the account next. A well-designed workflow returns a specific outcome, the reason the call stopped, everything it did capture and a recommended next step, never a bare "failed."
- Retries make sense only for temporary causes such as payer hours or dropped holds. Bad inputs, payer-side refusals and ambiguous answers need a fix, a different channel or a person.
- Evidence (recordings, transcripts, reference numbers, representative names, timestamps) is what lets a human pick up the account without redialing from scratch.
- When evaluating vendors, ask to see their unfinished accounts, not just their completed ones.
Ask an AI payer-calling vendor what its agent does when a payer won't give it an answer, and an honest reply starts with "that happens every day." Provider service lines close, phone trees change, calls get transferred into queues with different hours, and some representatives simply won't release a status over the phone. No caller, human or software, completes every payer call.
So the useful answer is about the account, not the call. When an AI agent can't get the answer, the account should come back to your team with a specific outcome, the reason it stopped, the fields it did capture and a recommended next step. The failure that really hurts an RCM operation is the account marked "failed" with no reason, or the one that never comes back at all and sits untouched while the timely filing clock runs.
What follows walks through where payer calls break, in roughly the order they break, and what should happen to the account at each point.
Why payer calls are long enough to fail in many places
The phone is still one of the slowest ways to get payer information. In the 2024 CAQH Index, the time medical providers and staff spent on a claim status inquiry by phone was the highest of any administrative task the report measured: 25 minutes per inquiry. CAQH also observed that although an electronic standard exists for claim status inquiries, providers and staff "frequently rely on time-consuming calls and faxes."
A 25-minute interaction has a lot of places to stop, and the failure points fall into five groups. Each one calls for a different response.
Before anyone answers: closed lines, wrong numbers and payer hours
The simplest failure is a call that never reaches anything useful. The provider services line is closed, the number routes to the wrong department, or the queue disconnects before anyone picks up. Hours differ by payer and often by department, so a call that is transferred late in the day can land in a unit that has already closed.
These causes are usually temporary, which makes them the right candidates for automatic retries. A sensible design reschedules the attempt inside the payer's hours, tries an alternate number when the first one routes badly, and logs each attempt on the account. It should not retry indefinitely: a well-designed workflow has a visible, configurable limit after which the account moves to a different channel or a person, with enough time left to act before any deadline.
Inside the IVR: inputs the phone tree won't accept
Payer phone trees are built around identifiers, and no two ask for them the same way. As SuperDial's post on IVR retrieval describes, one payer asks for the provider NPI first while another starts with the member ID, some accept spoken answers while others require keypad tones, and the path can change with the plan, the claim type or the number dialed. That variety produces three distinct IVR failures:
- Unrecognized input. The tree rejects a member ID format, a date or a spoken response it can't parse.
- Authentication failure. The payer can't match the caller to a provider or the request to a patient. The NPI and Tax ID combination may not be on file for that line, or the member ID may belong to a different plan.
- Changed menus. Phone trees, routing rules and authentication steps change, and a path that worked last month can lead to a dead end today.
The right response depends on which one occurred. An authentication failure caused by bad request data won't be fixed by calling again; the account should come back flagged as an input problem that names the field, so your team can correct it and resubmit. SuperDial's FAQ says that requests with a missing or incorrect input, such as a member ID, NPI or claim number, come back flagged as an input error so the team can fix the input and resubmit. A changed menu is the vendor's problem to solve. Affected accounts may need another channel or a person today, and the script needs updating before the next batch.
Some IVRs also stop offering certain answers by design. CMS Change Request 13754 directed Medicare Administrative Contractors to disable beneficiary eligibility information from their IVR systems by March 31, 2025, as a pilot involving most MACs, to protect beneficiaries from fraud. Under that instruction, providers check eligibility through the MAC's secure portal, billing agencies, clearinghouses or software vendors, or HETS. An agent that keeps asking a MAC phone tree for eligibility is asking a question the IVR was told to stop answering, so the account belongs in an electronic channel. The CR also says MACs must be prepared to re-enable the function if the pilot is discontinued, so check your MAC's current notices.
On hold and on the line: transfers, refusals and dead ends
Software doesn't get tired on hold, but holds still end badly. Lines drop after long waits, representatives transfer calls to departments with different hours and their own queues, and some calls end with a request for a callback number or a fax. A representative may ask a verification question the agent wasn't given data to answer, or may decline to release information by phone at all.
SuperDial's FAQ lists the most common reasons its agent comes back without an answer: the payer only releases that status through its portal, the line has no path to a representative, or the representative would not share the information. In those cases the request is marked unable to complete, with the reason, and a call summary is attached so the team can see what happened without replaying the call. Notice that none of those reasons is fixed by redialing the same number.
How long to hold is a policy decision, not just a technical one. Some questions justify a long wait because the phone is the only source. Others have a cheaper channel, and a well-designed workflow should know when a hold has stopped being worth it for that question and that payer.
Payers that restrict automated callers
A newer failure mode comes from the payer side. SuperDial's IVR retrieval post notes that some payer lines accept AI-led calls, while others restrict automated conversations or route them differently. When that happens, repeating the same representative-style call is unlikely to produce a different result.
The account needs a different route. Options include a portal or EDI check, a person making the call, or taking the answer directly from the payer's phone tree where that is possible. SuperDial says its IVR Retrieval capability is live for claim status workflows at select major payers, and that when the IVR doesn't have the answer, such as a denial without a reason, the workflow can continue through another channel or escalate to a conversation, depending on the payer and workflow.
When the answer is incomplete, contradictory or ambiguous
The most dangerous failure looks like a success. The call connects, the representative answers and the agent records something, but the answer doesn't settle the question. Part of the reason sits on the payer side. As SuperDial co-founder and CEO Sam Schwager explained on the Becker's CFO + Revenue Cycle Podcast, answering a provider's question can require the payer to reconcile several internal data sources that sometimes conflict (see our recap of that conversation). Common versions include a denial with no reason code, a status that conflicts with the electronic response your team already has, benefits quoted without saying whether they are in network or out of network, or an answer that seems to describe a different date of service.
When you evaluate how a workflow handles this, look for three safeguards. Does it define required fields up front, so an account isn't "complete" until every field the downstream decision needs is present? Does it ask clarifying questions on the call when an answer is ambiguous, since one more question costs less than another call? And when two sources disagree, does it return both with their sources instead of quietly choosing one, and route the account for review? Implementations vary by vendor, payer and workflow, so ask to see examples of each.
Partial answers still have value, so check whether a workflow keeps them. If the payer confirmed the claim is on file but wouldn't give a payment date, that confirmed field should stay on the account so the next attempt, in whatever channel, only chases what is missing.
Matching the next step to the cause
The pattern across all five groups is that the next step should follow the reason the call stopped. A general rule: retry what is temporary, fix what is wrong with the request, and reroute or escalate everything else quickly.
| Why the call stopped | Usually temporary? | Sensible next step |
|---|---|---|
| Line closed or outside payer hours | Yes | Retry inside the payer's hours |
| Disconnected during hold | Often | Retry, keeping the prior attempt on record |
| IVR rejected an input or authentication failed on bad data | No | Return as an input error naming the field; fix and resubmit |
| IVR menu changed | No | Route to another channel or a person; update the script |
| Payer only releases the answer through its portal | No | Switch to the portal or EDI |
| Representative refused, or required a fax or callback | No | Route to a person with the payer's instructions captured |
| Payer restricts automated callers | No | IVR, electronic channel or a person |
| Answer incomplete or contradictory | Depends | Clarify, try another source, or send to human review |
Identical retries on a non-temporary cause are the costliest mistake in this table. Each one burns days on accounts that were never going to resolve that way.
The evidence an unfinished account should carry
When an account comes back without an answer, the person who picks it up should be able to see exactly what was tried. At a minimum, that means the time of each attempt, the number dialed and the IVR path taken, the recording and transcript, any call reference number, the representative's name or ID, the fields captured so far, the fields still missing, the specific reason the call stopped and a recommended next step.
That record lets a human continue the work instead of starting over, and lets QA check captured answers against what the payer said. Reference numbers and representative names are also what your team will point to if the payer later disputes what it told you.
SuperDial's voice agents page describes this kind of handoff: when a transaction requires subjective judgment, is missing critical inputs or needs payer escalation or manual intervention, it routes a packet to the right person or team that includes what was tried, what was captured, what is missing and the recommended next step. Its claim status workflow lists a payer reference number, the next action, and transcripts or recordings when applicable among the data it returns.
Where human review fits
Humans belong in the loop for the accounts automation shouldn't resolve alone: conflicting answers, denials that need an appeal decision, inputs only the client can correct, and payer escalations. Human review also belongs on completed accounts. Because ambiguous answers can pass as completions, a regular QA sample of finished work, checked against the recording or transcript, is how you find the errors no outcome code will flag. The case for measuring completed tasks rather than automated calls is made in more depth in our post on completion rate versus automation rate; the account-level outcomes below are the operational side of that idea.
A recommended outcome taxonomy
Every account should leave an automated workflow with one clear outcome. The categories below are a recommended starting point for designing or evaluating a workflow, not any vendor's exact product states. Vendors name these differently; what matters is that each one maps to a distinct action on your side.
| Outcome | What it means | What your team does |
|---|---|---|
| Completed | Every required field captured, with evidence | Post the result and move the account forward |
| Partial | Some required fields captured; the missing ones are listed | Decide whether it is enough, or chase the remainder in another channel |
| Input error | The request had missing or incorrect data, with the field named | Correct the data and resubmit |
| Payer-side block | The payer won't release the answer by phone, has no path to a representative, or restricts automated callers | Switch channels |
| Needs human | Judgment, escalation or conflicting answers | Assign an owner with the evidence packet |
| Retry scheduled | A temporary failure, with the next attempt time | Monitor; no action yet |
A taxonomy like this turns failures into queues. Input errors go back to whoever owns the source data, payer-side blocks go to the team that works portals, and needs-human accounts go to someone with authority to decide.
Questions to ask a vendor about unanswered payer calls
Demos show completed calls. These questions get at everything else:
- What outcomes can an account come back with besides "completed," and can we see a real example of each?
- What reasons do you return when a call stops, and are they specific enough for us to route the account without listening to the recording?
- Which failures trigger automatic retries, and can we see and configure the limits and timing?
- What evidence comes back with an unfinished account: recording, transcript, reference number, representative name, captured fields?
- How do you handle payers that restrict automated callers or only release answers through a portal?
- When a payer's phone tree changes, how do you detect it, and what happens to the accounts already in flight?
- Are partially answered fields kept, so the next attempt only chases what is missing?
- In a pilot on our own queue, what share of accounts ended in each outcome?
The last question matters most. Outcome mix depends heavily on payer mix and workflow, so a vendor's numbers from someone else's queue tell you little about yours.
FAQ
How many times should an AI agent retry a payer call?
There is no universal number. Retries only make sense for temporary causes such as closed lines or dropped holds, and the limit should be set so the account still reaches a person or another channel with time to act before any filing or appeal deadline.
Is a partial answer from a payer call worth anything?
Yes, if it is kept. A confirmed claim receipt or eligibility status narrows what the next attempt has to find, and a workflow that discards partial answers forces the whole retrieval to start over.
