A CAQH profile could be completed, verified, and distributed to all insurance companies, but it does not guarantee that the process will go smoothly. The usual reasons for stalling are simple. CAQH records show a name that is different from the name on the license. The suite number can appear in two versions of the address. The taxonomy code registered at the federal level coincides with a different specialization.
The guide explains the cause of mismatches and how to resolve them. It includes a troubleshooting worksheet in its entirety for name, address, taxonomy code, and license number, and phases of updating.
Key Takeaways
- Reasons for delays: insurance companies compare CAQH with NPPES and state license files, and any inconsistency is flagged. Most problematic lines: name, address, taxonomy code, and license number.
- NPPES deadline: CMS states that suppliers are supposed to communicate changes in their address and licensing codes within 30 days.
- Best approach: check all records at least three times a year.
Why Payers Compare Your Records
CAQH stores what you tell it. It does not check the data for you. So a payer’s credentialing team checks your answers against other sources, and the two main ones are NPPES and your state licensing board.
The Three Records Payers Compare
| Record | What it holds | Who controls it |
| CAQH profile | Credentialing data you enter and attest | You |
| NPPES | Your NPI, name, practice location, and taxonomy code | You, in your NPPES account |
| State license record | Legal name, license number, status, and expiration | The state board |
When two of these records disagree, the payer cannot tell which one is right. The file goes into review, and review takes time.
Which Record Should You Treat as the Source of Truth?
Use the state license record as the reference for your legal name, license number, and license status. Use NPPES as the reference for your NPI, practice location, and taxonomy. Then make CAQH match both.
The 30 Day NPPES Rule
CMS says covered health care providers must notify NPPES of an address change within 30 days of the effective date. It gives the same 30-day limit for taxonomy changes. If you moved last quarter and only updated CAQH, your records are already out of step.
What to Update First
Most credentialing vendors recommend updating NPPES first, then waiting one day for the update to appear before updating CAQH. If CAQH is updated while NPPES still has the old information, a discrepancy could arise for any payer. We always follow this order, updating the state board record first with any name or license change.

CAQH, NPPES and State License Mismatch Fixes
| Field | Typical mismatch | Check against | How to fix it |
| Legal name | Maiden name in NPPES, married name on CAQH, missing suffix or middle initial | State license | When updating your name everywhere, use the name on your license. After updating, update the board record, followed by NPPES and CAQH, and provide proof of the name change. |
| Address | “Suite 400” in one place, “#400” in another, or an old location in NPPES | NPPES and your W-9 | Update NPPES within 30 days of a move, then match CAQH to it character for character. |
| Taxonomy | A specialist listed under a general specialty, or a code that does not fit the specialty | NPPES | Choose the primary taxonomy that matches your specialty and certification. Match CAQH to it. |
| License number | Transposed digit, wrong state, old number after renewal | State board lookup | Copy the number from the board record, correct CAQH, and upload the current license. |
| License status | Expired or lapsed license still listed | State board lookup | Always renew your license first and then upload a copy of the new license. |
| NPI | One wrong digit | NPPES | Use the NPI available in your NPPES record. Do not type it again. |
Name Mismatches
Names cause quiet delays because everyone assumes they match. Some typical causes of mismatches include the use of a married name in one place, a nickname, a missing middle initial, and suffixes such as Jr. or III.
What to Do After a Name Change
Update your state license first. Then go on to amend NPPES and CAQH, and retain the backup document in your files. According to CMS, an NPI does not have to change its number when a provider changes its name, as the number stays the same. This means that discrepancies are just administrative issues that can be easily resolved.
Use One Format Everywhere
Take the exact spelling, middle initial, and suffix from the medical license and use the same as in your W-9, malpractice certificate, and all payers’ forms. Consistency is more important than choosing the format.
Address Mismatches
An address looks simple until a payer’s system compares two strings. “123 Main St Suite 400” and “123 Main St #400” are the same office for a person, but they can get blocked by an automated check.
- Copy your address from the NPPES record into CAQH.
- Apply a similar format in your W-9, malpractice certificate, and payer contract.
- Check mailing and practice addresses separately. They can differ.
Taxonomy Mismatches
A taxonomy code describes your specialty. NPPES holds yours, and payers compare it with the specialty you list in CAQH.
Problems come up in a few ways. A specialist keeps an old general code. A resident becomes licensed and never changes the code. A provider earns a new certification and does not update. CMS asks newly licensed doctors to file taxonomy change information and asks those who are board certified in a new specialty to change the codes.
Credentialing vendors also report that only the primary taxonomy is used in automated checks, so make sure the primary one is the right one. Match it to the specialty on your CAQH profile and your payer contract.
License Number Mismatches
License errors are the easiest to fix and the easiest to miss. A single wrong digit, or a number from before a renewal, can stop verification.
- Open the state board lookup. Find your license under the exact name on file.
- Note down the number and the status in your tracker instead of retyping it.
- Check each state. In case, you have more than one license in different states, then you are required to provide the name of all states in your CAQH.
- Check the expiration dates. The date on CAQH should correspond with the board record and uploaded file.
- Upload the current license. An old PDF is a common cause of rejection.
How to Run a Mismatch Audit in 30 Minutes
You do not need any software, but rather three open tabs and paper.
- You do not need any software, but rather three open tabs and paper.
- Get access to your CAQH profile, NPPES record, and state board lookup.
- Fill in the same fields in the sheet below.
- Mark the discrepancies in every row where those do not correspond with each other.
- Fix the state record first, followed by NPPES and CAQH.
- Upload new documents and attest again.
Quarterly Reconciliation Sheet
| Field | CAQH | NPPES | State record | Match? |
| Legal name | ||||
| Practice address | ||||
| Primary taxonomy | ||||
| License number | ||||
| License expiration | ||||
| NPI |
This should be done every quarter and in the case of any changes in the location or name, or any new license received.
What to Do When a Payer Flags a Mismatch
- Ask the burdened party in question about the field and the source.
- Compare that field across the three records.
- Fix the source record first, then CAQH.
- Upload proof, such as a license copy or a name change document.
- Attest again, and send the payer a short note that the profile is corrected.
- Keep a record of the date and the payer contact.
Common Reasons Mismatches Keep Coming Back
- Staff retypes data instead of copying it.
- Only CAQH gets updated after a move.
- Nobody owns the quarterly check.
- Different forms use different name or address formats.
- Old documents stay uploaded after a renewal.
Hire one individual, and retain the document visible to the group.
Frequently Asked Questions
Which record should match first, CAQH or NPPES?
Cross-check CAQH with your local state license regarding both name and license details, as well as NPPES for all information about the NPI, address, plus the taxonomy. Update the source record before CAQH.
How long do I have to update NPPES after a move?
According to CMS, any healthcare provider that is covered must provide notice to NPPES within thirty days of the effective date of any address change.
Does my NPI change if I change my name?
No. CMS says that NPI is presumed to stay similar after a name change, but all necessary changes must be made to the records.
What taxonomy code should I use?
Choose the main taxonomy that fits with your specialty and certification, and promptly update it after acquiring a new license or board certification for another specialty.
Why does my CAQH profile show complete but a payer still stalls?
Completed does not equal verified. The insurance company compares your information with NPPES and state boards; any discrepancies can be detrimental to your file.
Do I need to attest again after fixing a mismatch?
Yes. Payers see changes after you attest again.
Can a billing company fix these mismatches?
Yes, with your approval. The provider still attests in their own account.
Final Thoughts
Most stalled CAQH profiles are not complicated. The two pieces of information present different information, and nothing was compared. Conduct an audit once every three months in order to correct the source records first and ensure you are using one format. Have your team do the work?
