What to Look for in a Credentialing Company: A Guide for Practice Owners

Credentialing is one of the most important and least understood processes in launching or growing a medical or dental practice. Until you are credentialed and enrolled with insurance payers, you cannot bill them. Until you can bill them, you are either seeing patients for free or turning away the majority of your market. For most new practices, the credentialing gap between opening your doors and receiving your first insurance payment is the single largest source of early-stage revenue loss, often costing $8,000 to $15,000 per month for primary care providers and $30,000 or more per month for specialists.

The process itself is exactly what you would expect from an industry that still faxes documents: slow, paperwork-intensive, payer-specific, and unforgiving of even minor errors. A single missing signature, an expired malpractice certificate, or a wrong taxonomy code can restart a 90-day clock without anyone notifying you. Most commercial payers take 90 to 120 days to process a credentialing application. Medicare and Medicaid can take longer. And every payer has its own application, its own requirements, and its own quirks.

This is why most practice owners outsource credentialing to a professional company. The right credentialing partner gets your providers enrolled faster, avoids the errors that cause costly delays, and handles the ongoing maintenance that keeps you in-network year after year. The wrong one submits your applications and disappears, leaving you to wonder why you are still not credentialed four months later.

The problem is that credentialing companies, like billing companies, all say the same things. Fast turnaround, payer expertise, full-service enrollment, dedicated support. Separating the companies that actually deliver from the ones that collect a fee and check a box requires knowing what to evaluate, what questions to ask, and what the best-run practices demand from their credentialing partners.

This guide is written from the practice owner’s perspective. It is based on what we have seen across hundreds of practices navigating the credentialing process, and on what consistently separates credentialing partners that protect your revenue from those that quietly cost you months of lost income.

Understand What You Are Actually Buying

Before you evaluate credentialing companies, you need to understand what credentialing actually involves, because the scope of what different companies include under the word “credentialing” varies enormously.

Credentialing in the strictest sense is the process of verifying a provider’s qualifications: education, training, licensure, board certifications, malpractice history, work history, and DEA registration. This is a background verification process, and it is a prerequisite for everything else.

Provider enrollment is the process of submitting applications to individual insurance payers so that your provider can participate in their network and bill for services. This involves completing payer-specific applications, submitting supporting documentation, and following up until the payer issues an approval and an effective date. Enrollment is where most of the time and effort lives.

Contracting is the negotiation and execution of a participation agreement with each payer. This is the step that determines your reimbursement rates, not just whether you are in-network, but how much you get paid. Many credentialing companies handle credentialing and enrollment but do not negotiate contracts on your behalf. Others include contract review and rate negotiation as part of their service.

CAQH profile management is the ongoing maintenance of your provider’s profile in the CAQH Provider Data Portal (formerly CAQH ProView), which is used by over 900 health plans as a centralized source of provider information. Your CAQH profile must be re-attested every 120 days. If your attestation lapses, payers lose access to your profile, claims can be placed on hold, and your in-network status can be jeopardized. A single missed attestation deadline can result in tens of thousands of dollars in denied claims within weeks.

Re-credentialing is the periodic renewal of your credentialing status with each payer, typically required every two to three years. Miss a re-credentialing deadline, and you can be dropped from a network without warning.

When a credentialing company tells you they handle “full-service credentialing,” ask them to define exactly what that includes. Does it include enrollment with all commercial payers, Medicare, and Medicaid? Does it include CAQH setup and ongoing attestation management? Does it include contract negotiation, or just application submission? Does it include re-credentialing and revalidation tracking? The answers will tell you whether you are buying a complete solution or a partial one that leaves critical gaps.

The best credentialing companies handle the entire provider lifecycle: initial credentialing, CAQH management, payer enrollment, contract review, EFT and ERA setup, re-credentialing, and demographic updates. They manage this end-to-end with a single point of contact so nothing falls through the cracks. The worst ones handle “credentialing” but not enrollment, or enrollment but not re-credentialing, leaving you with gaps between processes that create delays and dropped applications.

Timelines and Follow-Up Are Where the Money Is

The most expensive thing about credentialing is not the fee you pay the credentialing company. It is the revenue you lose during the enrollment gap, the period between when your provider starts seeing patients and when payers approve their applications and begin processing claims.

For a primary care physician generating $40,000 per month in collections, a two-month delay in credentialing costs $80,000 in lost or delayed revenue. For a specialist generating $75,000 or more, the math is even more painful. A credentialing company that charges $3,000 but gets you enrolled two months faster than a company that charges $1,500 has saved you tens of thousands of dollars. The cheapest credentialing service is almost never the most cost-effective one.

This is why follow-up is the single most important operational capability a credentialing company can have. Submitting an application to a payer is the easy part. What happens after submission is what determines whether you are credentialed in 90 days or 180 days. Payers lose documents, request additional information, assign applications to reviewers who sit on them for weeks, and fail to communicate status updates. A credentialing company that submits your application and waits for the payer to respond is a credentialing company that is not doing its job.

Ask specifically: what is your follow-up cadence after an application is submitted? How often do you contact each payer to check on application status? Do you have dedicated contacts at the major payers in my market, or are you calling the same general enrollment phone line that anyone can call? How quickly do you respond when a payer requests additional documentation?

The best credentialing companies follow up with payers every one to two weeks and have established relationships with payer enrollment departments that allow them to resolve issues faster than a practice could on its own. They track every application in a system that shows you the real-time status of each submission, not a spreadsheet that gets updated when someone remembers to check. They alert you immediately when a payer requests additional information, because a document request that sits unanswered for two weeks can push your effective date back by a month or more.

Transparency Into Application Status

You should be able to see the status of every credentialing application at any time, without having to email or call your credentialing company and wait for a response.

Many credentialing companies provide updates through periodic emails or phone calls. Some send a monthly status report. That level of visibility is not enough. If an application has stalled because a payer requested a document three weeks ago and nobody followed up, you need to know that immediately, not at the end of the month.

The best credentialing partners provide a live dashboard or portal where you can see every application, its current status, the payer it was submitted to, the date of submission, any outstanding requests from the payer, and the projected timeline for approval. You should be able to see which applications are on track and which ones are stuck, and why.

If a credentialing company cannot provide this level of transparency, or if they tell you they will “keep you updated” without explaining how, that is a significant red flag. You are trusting this company with a process that directly determines when your practice starts generating revenue. You should never be in a position where you have to chase your credentialing company to find out what is happening with your own applications.

Specialty and Market Knowledge

Credentialing is not the same across all specialties and all markets. A behavioral health provider credentialing with Medicaid in New York faces a fundamentally different process than a dermatologist enrolling with commercial payers in Texas. Payer-specific requirements vary by state, by specialty, and by provider type. The forms are different. The timelines are different. The documentation requirements are different. The payers that matter most to your revenue are different.

A credentialing company that handles your specialty regularly will know which payers require additional documentation beyond the standard application, which payers have closed networks in your area and how to navigate appeals, which payer enrollment departments are responsive and which ones require persistent follow-up, and what the realistic timeline is for each payer in your market. A generalist company applying the same approach across all specialties and all geographies will miss these nuances, and those misses cost you time.

Ask what percentage of the credentialing company’s clients are in your specialty. Ask which payers they work with most frequently in your state or region. Ask whether they have experience with the specific payers you need to enroll with. If you are a new practice, ask whether they have experience credentialing providers who do not yet have an established patient panel, because some payers treat new practices differently than established ones, and some require additional documentation or site visits before approving enrollment.

Pricing That Makes Sense for Your Situation

Credentialing companies use several pricing models, and the right one depends on your practice size, provider count, and the number of payers you need to enroll with.

Per-payer pricing charges a flat fee for each insurance company your provider enrolls with, typically ranging from $100 to $300 per payer per provider. This model is transparent and scalable. You pay for exactly what you need. If you are enrolling one provider with eight payers, you can calculate your cost precisely. This model works well for solo practitioners and small practices with a defined payer list.

Flat fee per provider charges a single fee to credential and enroll a provider across a standard panel of payers, typically ranging from $2,500 to $5,000 per provider. This model bundles the work and is simpler to budget for, but you need to understand exactly which payers and services are included. Some companies define “standard panel” as five payers. Others include ten or fifteen. The difference matters.

Monthly retainer charges a fixed monthly fee that covers credentialing, enrollment, CAQH management, and ongoing maintenance. This model works well for multi-provider practices that need continuous credentialing support as they hire new providers and manage re-credentialing cycles. Monthly retainers typically range from $100 to $350 per provider for maintenance after initial enrollment is complete.

Percentage of collections is less common for standalone credentialing but appears in bundled credentialing-and-billing packages. Be cautious with this model for credentialing specifically, because the incentive alignment that makes percentage-based billing effective does not translate as cleanly to credentialing work.

Regardless of the pricing model, watch for hidden costs. Setup fees, CAQH profile creation fees, rush processing fees, re-credentialing fees, and fees for adding payers after the initial enrollment are all common add-ons that can increase your total cost by 20 to 40 percent above the headline rate. Ask for a complete, written breakdown of all costs before you sign anything. The best credentialing companies are upfront about their pricing because they compete on the value of their work, not on burying fees in fine print.

Do not choose a credentialing company based on price alone. A company that charges $150 per payer but takes six months to get you enrolled has cost you far more than a company that charges $250 per payer and gets it done in three. The revenue you lose during a credentialing delay will always exceed the difference in fees between a cheap credentialing service and a good one.

CAQH Management Is Not Optional

Your CAQH Provider Data Portal profile is the foundation of your entire credentialing and enrollment process. Over 900 health plans pull provider data directly from CAQH when processing credentialing applications, re-credentialing reviews, and directory updates. If your CAQH profile is incomplete, inaccurate, or expired, everything downstream breaks.

CAQH requires providers to re-attest their profile every 120 days, confirming that all information is current and accurate. If you miss the re-attestation deadline, your profile status changes to expired, and payers lose access to your data. The consequences can be immediate and severe. Claims can be placed on hold. Re-credentialing applications can stall. In some cases, payers have treated an expired CAQH profile as a voluntary termination, triggering a de-credentialing process that takes months to reverse.

This is not a theoretical risk. Practices that manage CAQH attestation internally, through a busy office manager who has a dozen other responsibilities, routinely miss the 120-day window. All it takes is one forgotten deadline during a hectic quarter to trigger a cascade of denied claims.

Any credentialing company you hire should manage your CAQH profile as a core part of their service. That means initial profile setup, document uploads, ongoing updates whenever your information changes (new address, new license, new malpractice policy), and proactive management of the 120-day re-attestation cycle so that your profile never lapses. If a credentialing company does not include CAQH management in their standard service, or if they charge it as an add-on, ask why. It is not a supplemental service. It is foundational to everything else they do.

Contracting and Fee Schedule Negotiation

Getting credentialed and enrolled with a payer gets you in-network. Contracting determines how much you get paid. These are two different things, and many practice owners do not realize the distinction until they receive their first explanation of benefits and discover that their reimbursement rates are lower than they expected.

When a payer approves your enrollment, they send you a participation agreement with a fee schedule attached. That fee schedule specifies the maximum amount the payer will reimburse for each procedure code. Most practice owners sign the contract without negotiating, either because they do not know negotiation is possible or because they are desperate to start billing and do not want to delay the process further.

This is a mistake that costs practices thousands of dollars per year, every year, for the life of the contract. Reimbursement rates are often negotiable, particularly for providers in high-demand specialties or underserved areas. Even a modest improvement in rates, five to ten percent above the initial offer, compounds into significant revenue over time.

Some credentialing companies include contract review and fee schedule negotiation as part of their service. Others handle enrollment only and leave contracting to you. If your credentialing company does not negotiate on your behalf, you should either negotiate yourself (with guidance from a healthcare attorney or consultant) or find a credentialing partner that includes this service. Signing a payer contract without reviewing the fee schedule is the equivalent of accepting the first salary offer without negotiating. You might get a fair deal, but you will never know.

The Team Working Your Account

Credentialing is detail-intensive, relationship-dependent work. The person handling your applications needs to be meticulous with documentation, persistent with follow-up, and knowledgeable about payer-specific requirements. The quality of the individual assigned to your account matters as much as the company name on the contract.

Ask how the credentialing company assigns accounts. Will you have a dedicated credentialing specialist, or will your account be handled by whoever is available? What is the ratio of clients to staff? If one specialist is managing credentialing for 50 providers simultaneously, the follow-up cadence that your applications require is not happening.

Ask whether the staff are W-2 employees or independent contractors. Credentialing companies that use contractors often have higher turnover, which means the person who learned the details of your practice, your payer mix, and your application history may be replaced without your knowledge. Institutional knowledge matters in credentialing. A specialist who has been managing your account for six months knows which of your applications are stalled, which payers need more aggressive follow-up, and what documentation issues have come up in the past. A new person inheriting your file starts from scratch.

Ask how you will communicate with your credentialing team. The best credentialing partners assign you a named point of contact who is reachable by phone or email during business hours and responds within a reasonable timeframe. They check in proactively rather than waiting for you to call with a question. If your credentialing company is unresponsive or hard to reach, that same lack of urgency is almost certainly reflected in how they follow up with payers.

Contract Terms and Data Ownership

Read the credentialing company’s service agreement carefully. Pay attention to the contract length, the cancellation terms, and what happens to your data if you leave.

The best credentialing companies offer month-to-month or short-term agreements with 30 days notice to cancel. They earn your business every month based on performance. A credentialing company that requires a 12-month commitment with early termination fees is signaling that they expect you to want to leave before the contract is up.

Your credentialing data, including your CAQH profile information, payer application records, enrollment confirmations, contract documents, and re-credentialing timelines, belongs to you. The service agreement should clearly state that the credentialing company will provide a complete data export upon termination, in a usable format, within 30 days, and at no additional cost. If the contract is silent on data portability, add it before you sign.

Ask what happens to applications that are still in process if you terminate the relationship. A responsible credentialing company will continue to work applications that were submitted before the termination date and ensure a clean handoff to your new credentialing partner or internal team. A company that abandons in-progress applications when you leave can cost you months of wasted work.

Red Flags to Watch For

Across the hundreds of practices we have worked with, certain patterns consistently signal a credentialing company that will underperform or, worse, cost you revenue.

They cannot explain their process. If you ask a credentialing company to walk you through their workflow from the day you sign until your provider is fully enrolled and billing, and the answer is vague or generic, they do not have a systematic process. Credentialing is process-driven work. A company that cannot clearly articulate their steps, timelines, follow-up cadence, and escalation procedures is a company that is making it up as they go.

They guarantee specific timelines without caveats. No credentialing company can guarantee that a payer will approve your application in a specific number of days. Payer processing times are outside anyone’s control. A company that promises “credentialing in 30 days” is either being dishonest or does not understand the process. What they should be able to tell you is their average turnaround time by payer, what they do to minimize delays, and how they handle applications that stall.

They require full payment upfront. Credentialing is a process that unfolds over weeks or months. A company that demands the entire fee before doing any work, with no milestone-based structure and no refund policy, is a significant risk. Legitimate credentialing companies either bill per milestone (profile setup, application submission, enrollment confirmation) or offer reasonable payment terms that align with the work being done.

They do not handle CAQH. A credentialing company that does not include CAQH profile management in their standard service is leaving a critical piece of the process unmanaged. CAQH is not an add-on. It is the central hub that payers use to access your provider data. If your credentialing company is not managing it, who is?

They have no reporting or tracking system. If the credentialing company cannot show you where each application stands at any given time, they are tracking your enrollment process in email threads and spreadsheets. That approach works until it does not, and when it fails, you are the one who loses revenue.

They do not discuss contracting. A credentialing company that never mentions fee schedules, reimbursement rates, or contract terms is focused on getting you enrolled without any attention to how much you will be paid. Enrollment without contract negotiation is half the job.

They resist giving references. Any credentialing company worth hiring should be able to provide references from practices similar to yours in size, specialty, and market. If they cannot, or if they hesitate, that tells you something about the consistency of their results.

When to Start Credentialing

Start credentialing as early as possible. It is the longest lead-time item in the entire practice startup process and the one that catches new owners off guard most often.

You can begin the credentialing process as soon as you have your NPI number, your legal entity formed, and a business address. The address does not need to be your permanent practice location. Many providers begin credentialing using a registered agent address or a temporary address and update it once their permanent space is secured. Submit applications to every payer you intend to accept simultaneously. Do not do them one at a time.

For new practices, credentialing should begin at least four to six months before your target opening date. This gives your credentialing company enough time to complete CAQH setup, submit applications to your full payer panel, follow up through the approval process, and handle any documentation issues or resubmissions that arise along the way.

If you wait until your buildout is nearly complete to start credentialing, you will almost certainly open your doors before your payer enrollments are approved. That means seeing patients for weeks or months without the ability to bill their insurance, creating a cash flow gap that can put real financial pressure on a new practice.

How We Evaluate Credentialing Partners

At New Practice Guide, we work with medical and dental practices across the country at every stage, from startup through expansion. Through that work, we have developed relationships with credentialing companies in every major market and across specialties.

We evaluate credentialing partners on the same criteria outlined in this guide: scope of service, follow-up discipline, transparency, payer-specific expertise, pricing fairness, contract terms, and the quality of the team assigned to each account. We track which credentialing companies consistently deliver results, measured by enrollment timelines and provider satisfaction, and which ones consistently underperform.

When a practice comes to us needing a credentialing partner, we do not hand them a list. We match them with the credentialing company that fits their specialty, their market, and their size, and we stay involved to make sure the relationship is working.

If you are evaluating credentialing companies and want to understand which partners perform best in your market and specialty, we are happy to share what we know.

Frequently Asked Questions

How much does outsourced credentialing cost?

Costs vary based on your provider count, specialty, and number of payers. Per-payer pricing typically ranges from $100 to $300 per payer per provider. Flat fee per provider models typically range from $2,500 to $5,000 for initial credentialing across a standard payer panel. Ongoing maintenance, including CAQH attestation, re-credentialing, and demographic updates, typically runs $100 to $350 per provider per year. Always get a complete cost breakdown before signing, including any setup fees, rush fees, or add-on charges.

How long does credentialing take?

Most commercial payers take 90 to 120 days to process a credentialing application. Medicare can take 60 to 90 days. Medicaid timelines vary by state but can exceed 120 days. These timelines assume a clean, complete application with no errors or missing documentation. A single mistake can add 30 to 60 days to the process. A good credentialing company minimizes these delays through thorough application preparation and aggressive follow-up with payers.

Should I do credentialing in-house or outsource it?

For most practices, outsourcing is more cost-effective and produces faster results. A single credentialing application takes 10 to 20 hours of staff time per payer, including document collection, form completion, and follow-up. Across five to ten payers, that is 50 to 200 hours per provider. Your office staff spending that time on credentialing instead of patient care and revenue-generating activities is rarely a good trade. More importantly, credentialing errors made by staff who do this occasionally are far more common than errors made by specialists who do this every day. A single mistake that delays enrollment by one month costs more in lost revenue than most credentialing companies charge for their entire service.

What is CAQH and why does it matter?

CAQH (the Council for Affordable Quality Healthcare) operates the Provider Data Portal, a centralized database used by over 900 health plans to access provider credentialing information. Instead of submitting separate documentation to every payer, providers enter their information in CAQH once, and payers pull from that shared database. Your CAQH profile must be re-attested every 120 days to remain active. If it expires, payers may place claims on hold, delay re-credentialing, or treat the lapse as a voluntary termination. CAQH management should be a core service of any credentialing company you hire.

What is the difference between credentialing and contracting?

Credentialing verifies a provider’s qualifications. Enrollment gets the provider approved to participate in a payer’s network. Contracting is the negotiation and execution of a participation agreement that sets your reimbursement rates. Most practice owners focus on credentialing and enrollment without paying enough attention to contracting, which determines how much they actually get paid for every service they deliver. A credentialing company that handles contract review and fee schedule negotiation provides significantly more value than one that handles enrollment alone.

What happens if I switch credentialing companies?

Your credentialing data belongs to you. A responsible credentialing company will provide a complete data export upon termination, continue working any applications that were submitted before the termination date, and facilitate a clean handoff to your new provider. Plan for 30 to 60 days of overlap between the outgoing and incoming credentialing companies to ensure no applications are dropped and no re-credentialing deadlines are missed during the transition.

What questions should I ask a credentialing company before signing?

Ask them to walk you through their process from start to finish. Ask what their average enrollment timeline is by payer. Ask how often they follow up with payers on pending applications. Ask to see their reporting dashboard or tracking system. Ask what percentage of their clients are in your specialty. Ask whether they handle CAQH management, contract negotiation, and re-credentialing. Ask about their pricing structure, including all fees. Ask about their contract terms and cancellation policy. Ask what happens to your data and in-progress applications if you terminate. And ask for references from practices similar to yours in size, specialty, and market.
