Questions to Ask a Credentialing Company Before You Hire Them

What the Right Vendor Should Make Predictable

A credentialing company should make payer enrollment more predictable, not just take forms off the practice's desk. The right vendor organizes documents, sequences payer submissions, monitors CAQH (required every 120 days), follows up with payers, and reduces avoidable billing delays. The wrong vendor creates a quiet backlog that surfaces only when claims start denying months later.

Use these questions with every vendor on your shortlist. Require specific answers, sample reports, and written scope before the first invoice. If a vendor cannot explain its process by payer, provider, and deadline, it is not ready to manage enrollment work that affects cash flow.

1. What Exactly Is Included in Scope?

Ask whether the engagement includes each of the following -- do not assume:

1. Initial provider credentialing (document collection and review)
2. CAQH ProView setup
3. CAQH reattestation management (required every 120 days; who owns this?)
4. Individual NPI and taxonomy verification
5. Medicare PECOS enrollment or reassignment
6. State Medicaid enrollment
7. Commercial payer applications (how many payers? which types?)
8. Group reassignment and entity linking
9. Payer follow-up cadence (how often, for how long after submission?)
10. Returned application correction
11. Post-approval billing handoff (how does billing learn each payer is ready?)
12. Roster maintenance and ongoing updates
13. Recredentialing at contract cycle end
14. Rush or priority services if a start date is time-sensitive

"Full-service credentialing" is not a scope. A line-item list is. Most delays and billing problems trace to gaps in scope that were not defined before work started.

2. Which Payers and Specialties Do You Handle Most Often?

A capable vendor should know the procedural differences between Medicare PECOS, state Medicaid, major commercial plans, and specialty delegated networks. Ask for specific examples from your payer mix.

Use the GPH scorecard framework to organize this conversation:

Scorecard category	What to ask the vendor
Technology and integration	How do you track applications, CAQH, documents, and payer status? What tool does the practice see?
Financial performance	How do you reduce delayed effective dates and billing holds? What outcome data can you show?
Transparency and reporting	What does the weekly status report look like? Ask to see a sample.
Service and support	Who is the named coordinator? What is the response SLA? How are escalations handled?
Compliance and security	Will you sign a BAA? How is PHI and document access controlled? What audit trail exists?

For specialty practices -- behavioral health, chiropractic, optometry, orthopedics, urgent care -- ask specifically whether the vendor has done enrollment for your specialty at your target payers. Specialty-specific enrollment errors (taxonomy codes, modifier requirements, delegated network structures) are not obvious to generalist credentialing staff.

3. What Timeline Should We Expect, and What Starts the Clock?

Ask for timeline ranges by payer type, not a single blended estimate. Medicare PECOS typically closes in 30-90 days; commercial payers generally run 60-120 days; some Blues plans closer to 90 days; United typically 90-120 days. Verify current payer-specific timelines with the vendor based on recent client experience.

Also ask: - What starts the clock -- document receipt from the practice, CAQH attestation, application submission to the payer, or payer acknowledgement? - What does the vendor do when a payer goes silent for more than two weeks? - How are blocked applications escalated?

A vendor that waits passively for payer responses is not managing the process -- it is tracking it. Active follow-up every two weeks per application is standard for a well-run credentialing engagement.

4. How Do You Confirm Billing Readiness After Approval?

Approval is not the same as billing readiness. A payer can approve an application and still fail to correctly load the provider's NPI, taxonomy code, effective date, group relationship, or billing location. Claims submitted against a correctly approved but incorrectly loaded provider will reject.

Ask the vendor: - How do you confirm the payer has loaded the provider correctly? - What documentation does the billing team receive before claims go out? - Who confirms the effective date is correctly reflected in the billing system?

If the vendor considers the job complete when an approval letter arrives, there is a gap between their finish line and yours.

5. What Do You Need From Our Practice?

Credentialing delays often start inside the practice. Ask for the vendor's complete intake checklist before signing. A clean intake checklist should request:

• State license (confirm expiration date)
• DEA registration if applicable
• CAQH ProView login and current attestation status
• NPI records and taxonomy codes
• Full CV with no work history gaps
• Education and training documentation
• Board certification if applicable
• Malpractice coverage face sheet
• W-9 and tax ID
• Group NPI and entity documentation
• Banking and EFT information for payers
• Practice locations and addresses
• Payer list with priority order

A vendor that cannot produce a clean intake checklist is making assumptions about what you will provide. Missing documents that surface mid-project are the most common source of timeline slippage.

6. How Will We See Status?

Ask to see a sample status report -- not a description of one. The report should show: - Provider name - Payer name and type - Application submission date - Current status - Next action required and owner - Current blocker (if any) - Last follow-up date and contact - Expected effective date - Notes from payer calls or portal checks

Monthly reporting is too slow for active enrollment work. Weekly is the minimum for new provider onboarding. High-volume projects may need twice-weekly updates. Practices that discover enrollment problems from a declined claim rather than a vendor status update are working with a vendor that is not communicating effectively.

7. What Are Your Fees and What Is Excluded?

Credentialing pricing varies by vendor and scope -- per provider, per payer, monthly retainer, or project-based. Verify current pricing from vendor quotes. Ask specifically what is excluded from the quoted price:

• CAQH maintenance and reattestation
• Medicare and Medicaid enrollment (often separate line items)
• Commercial payer follow-up after initial submission
• Returned application rework
• Delegated credentialing organizations (Optum, Magellan, Beacon)
• State-specific supplemental forms
• Rush processing fees
• Recredentialing at contract cycle end

If a quote is meaningfully cheaper than competing quotes, identify which items are excluded. Missing exclusions typically show up as scope gaps or billing disputes mid-project.

8. How Do You Protect Provider and Practice Data?

Credentialing files contain sensitive personal and professional information -- SSNs, license numbers, malpractice history, board sanctions. Ask:

• Will you sign a BAA before receiving any documents?
• How is access to provider records controlled within your team?
• Are all access events logged with an audit trail?
• What is your data retention policy?
• What is your breach notification procedure and timeline?

No BAA should stop the evaluation immediately. Any hesitation on basic security documentation is a disqualifying signal when the vendor will have access to PHI and professional history.

9. Can We Speak With References Like Us?

Ask for references from practices similar in size, specialty, and payer mix. Then ask those references:

1. Were payer timeline estimates accurate?
2. Did the vendor communicate blockers before they became problems?
3. Were any claims delayed because payer loading was incorrect after approval?
4. What specifically did the vendor do well?
5. What would you do differently?

References that say only "they are great" are not useful for evaluation. You need to know whether a missed CAQH reattestation, a returned application left unresolved for six weeks, or a billing handoff problem caused a revenue delay.

10. What Happens After Initial Enrollment?

Ongoing credentialing maintenance includes: CAQH reattestation every 120 days, license renewals, DEA renewals, malpractice renewals, Medicare PECOS revalidation every 5 years, commercial payer recredentialing every 2-3 years, roster updates, address changes, and ownership change notifications. Ask whether the vendor handles ongoing maintenance or only the initial enrollment project.

For many practices, the vendor that submits the fastest initial enrollment is not the right long-term choice if the credentialing calendar drifts after the launch project closes. A vendor with an ongoing maintenance program that provides automatic calendar alerts, annual recredentialing outreach, and CAQH reattestation reminders may be worth more than a vendor with faster initial submission if the practice cannot manage the calendar internally.

How to Use These Answers

After each vendor call, score the answers across the five GPH scorecard categories while the conversation is still fresh. Give the highest scores to vendors that provide a sample payer tracker, define scope at the line-item level, explain payer-specific follow-up procedures, and treat BAA and security as requirements, not options. Give low scores to vendors that answer with general claims and no process detail.

The final decision should match the vendor's strength to the practice's actual problem: speed to launch, backlog cleanup, complex payer mix, multi-provider roster, or ongoing maintenance. Being good at credentialing and being the right fit for a specific project are different things.
