From 994 recorded payer calls, not a template
How to follow up on a credentialing application
We transcribed 92.7 hours of our own payer follow-up calls: 994 of them. This guide is what those calls teach. What reps ask for, how they deflect, and the questions that turn "still in process" into a real answer.
Why the follow-up call decides the timeline
Payers do not call you when your file stalls. A missing document sits unnoticed. A file lands in the wrong queue and stays there. A CAQH attestation quietly lapses mid-review and the clock silently resets. Each of these adds 30 to 60 days, and none of them announces itself. The follow-up call is the only instrument that finds a stall while it is still cheap to fix.
Here is what the phone data says about the work itself. Half of all dials never reach a person: across our 994 recorded calls, 49 percent ended in a no-answer or voicemail. The calls that connected ran a median of 7 and a half minutes, and the slowest tenth passed 21. Budget for that reality. A practice that plans five minutes for "a quick status check" abandons the call right when the queue would have cleared.
What the rep will ask you, in order
Before a payer rep discusses anything, they verify who you are. Most guides tell you to lead with the NPI. Our call data says the NPI comes third. Here is what reps actually demanded, counted across every one of the 994 calls:
| What they ask for | Times asked | What to know |
|---|---|---|
| Tax ID (full nine digits) | 682 | The most requested identifier by a wide margin. Have all nine digits, not the last four. |
| Practice address | 558 | Exactly as filed. A suite number mismatch triggers a verification detour. |
| Individual NPI | 525 | Third, not first. Most guides tell you to lead with it. The phone data says otherwise. |
| Phone number on file | 244 | The number on the application, which is not always your front desk line. |
| Reference number | 146 | From the prior call. This is why you never end a call without one. |
| Provider name and DOB | 227 | Spelled slowly. Reps type while you talk. |
Put these on one sheet before you dial: full tax ID, address exactly as filed, individual NPI, group NPI, the phone number on the application, the submission date, and any reference number from a prior call. A rep who gets clean answers in ten seconds treats the rest of your call differently. One who has to wait while you dig through email does not.
The six deflections, and what to say back
Reps deflect the same ways at every payer. We counted nine distinct patterns across the corpus; these six cover nearly every call you will make. None of the responses argue. Every one of them converts a dead end into either a specific item or a tracked commitment.
"We need more information."
"Happy to get that over today. Exactly which document or field is missing, and where should it go?" Then read it back. Never leave the call without the specific item named.
"Call back in a few weeks."
"I will. What date should I call back, and is there a reference number for today so the next person can pick this up?" A date and a reference turn a brush-off into a tracked commitment.
"The provider is not in our network."
"That may be what shows today. We submitted on [date]. Can you check for a pending application under the tax ID rather than the individual NPI?" Group versus individual records cause most false negatives.
"Just check the portal."
"The portal shows no change, which is why I am calling. Can you see anything on your side the portal does not show?" The portal is why you called. Do not accept it as the answer.
"It is still in process."
"So I can note it correctly: is the file waiting on you, waiting on primary source verification, or waiting on something from us?" Those three answers lead to three different next moves, and reps will usually pick one rather than repeat themselves.
"I cannot give you a time frame."
"Understood. Two things then: is the file complete on your end, and what time frame are you typically seeing right now?" Ask once. If they hold firm, take the name and reference and close.
Never hang up without these four things
- The representative's name.
- A reference number for the call. If the payer does not issue them, note the rep's name, extension, and the exact date and time instead.
- The status in the rep's own words, not your paraphrase.
- What happens next and when: the specific outstanding item, or the expected time frame, or the date you should call back.
This is not bookkeeping. A dated record of who said what is the only thing that makes a later escalation possible, whether that is a supervisor, the payer's provider relations representative for your group, or in the rare worst case a state insurance department complaint. You never mention any of that on the phone. The record works precisely because it is collected politely, one call at a time.
The clock starts at complete, not at submitted
Some states put a legal deadline on credentialing decisions. Where those statutes exist, every one of them starts the clock at a complete application. The rep's first move against any deadline talk is to say the file was incomplete, which restarts it. So the question that actually protects you is not "when is my deadline" but "is the file complete on your end, and as of what date?" Pin the completeness date on a call, with a reference number, and the clock becomes real.
And before blaming the payer, check the stall that lives on your side of the fence. An expired CAQH attestation is the most common silent killer we see. If a rep says the file is waiting on you, ask whether CAQH shows attested and current, and what attestation date they can see. Our CAQH guide covers keeping that profile clean.
The cadence that actually works
Confirm receipt within 5 business days of submission. Then a status call every 10 to 14 business days, every touch logged with a name and reference. Respond to any payer request within 2 business days, because your response time is the one part of the clock you fully control. After a stated time frame passes with no decision, the tone changes from checking in to asking what specifically is outstanding and who is holding it.
That discipline is simple and it is relentless, which is exactly why practices stop doing it around week six. It is also, frankly, the reason our service exists: this cadence is the process we run for every application we manage, with every call logged the way this guide describes.
Where these numbers come from
Every figure on this page is a count from 994 recorded credentialing follow-up calls made by our own team, 92.7 hours of audio, transcribed and tallied in mid-2026. Nothing here is an industry estimate or a template we found. When the data changed our assumptions, we changed the guide: we expected the NPI to be the most requested identifier, and we were wrong.
Common questions
How often should you follow up on a credentialing application?
Every 10 to 14 business days once the application is submitted, and within 2 business days of any request from the payer. Weekly is too often for most payers and irritates the reps who control your file. The cadence that works is steady and boring: same identifiers, same questions, logged every time.
What should I have ready before calling a payer about credentialing?
The tax ID, the practice address, and the NPI, in that order. Across 994 of our recorded payer calls, reps asked for the tax ID 682 times, the practice address 558 times, and the NPI 525 times before discussing anything. Have the group NPI too: individual and group records are filed separately, and a rep searching the wrong one will tell you the provider does not exist.
What if the payer says my application is not in the system?
Ask them to search by tax ID instead of NPI, then by the practice name, then by the group NPI. Group and individual records live in different places at most payers, and this mismatch is the most common false negative we see. If it is genuinely absent, ask the rep to open a ticket and give you the ticket number before you hang up.
The rep will not give me a time frame. What then?
Do not accept a shrug and move on. Ask two things: is the file complete on your end, and what time frame are you typically seeing right now? Completeness matters because every payer clock starts at a complete application, not at submission. If the rep holds firm, take their name and a reference number and close politely. You are building a dated record, and that record is what makes any later escalation work.
Does calling actually speed up credentialing?
Calling does not shorten a payer's committee calendar. What it does is catch the silent stalls: a missing document nobody emailed you about, a file parked in the wrong queue, a CAQH attestation that lapsed mid-review. Each of those quietly adds 30 to 60 days when nobody is watching. The practices that get credentialed fastest are not the ones that call the most, they are the ones that never let a stall run for three weeks unnoticed.
