Credentialing vs Licensing: What’s the Difference? (Guide)

People often use the terms “credentialing” and “licensing” to refer to the same thing, but they are actually two distinct processes that serve different purposes. A doctor can legally practice medicine in a state if they have a license. Credentialing is what lets that doctor work with an insurance company and bill for the care they provide. Even if a doctor has a license, they may not be able to receive payment from insurance companies until all their credentials are in order. It is important for practices that want providers to see patients and get paid on time for these two processes to understand how they vary and how they depend on each other. 

What is Medical Credentialing? 

Medical licensing is the process of making sure a provider is qualified so they can work with insurance companies and get paid for their services. It checks a provider’s work experience, education, training, licenses, board qualifications, and fraud record, and then it signs them up with certain insurance plans. 

Payers, hospitals, and licensing groups are all involved in the process of certification. It’s not a one-time thing. When providers join a network, they are given original credentials. They are then recredentialed regularly, usually every two to three years, to keep their current enrollment. Most business companies use the CAQH database to store information about credentials, while PECOS is used for Medicare enrollment. 

Credentialing’s main purpose is to give people access to money. A service can’t bill people who aren’t in their network if they don’t have current credentials. Every client connection that affects a practice’s income rests on having up-to-date, correct credentials. 

What is Medical Licensing? 

A medical license is the official document a state medical board issues to a doctor that lets them practice medicine in that state. This is the basic condition on which all other authorizations, like credentials, depend. 

A doctor needs to get a medical degree from an approved school, pass all three parts of the USMLE, finish the residency training, and send in an application for their state that includes primary-source proof and a background check in order to get a license. Because licensing is controlled by each state, a license from one state does not allow you to work in another. A doctor who works with patients in more than one state, even though via video, needs to have a current license in each state where those patients are based. 

With a license, you can answer one formal question: Is this service allowed to practice medicine in this state? It does not say which insurance networks the business works with. That’s what credentials are for. 

Credentialing vs Licensing: Key Differences 

The easiest way to explain the difference is this: a license makes it legal to practice medicine, while credentials allow you to get paid by insurance companies. Providers need both, and one can’t be used instead of the other. 

Credentialing Process Explained 

Once a provider has a valid license, they can start getting credentials. First, the main source verification step is taken. This is when the credentialing body checks the education, training, and license directly with the institutions that issued them instead of using copies that were sent in. The OIG checks to see if a doctor has been excluded, and the National Practitioner Data Bank looks at their malpractice history. 

After proof, the source is added to the payers’ list. The Medicare side of this goes through PECOS. For business payers, it usually goes through CAQH, and each payer sets its own enrolment process and schedule. The supplier sends in or changes their CAQH profile, confirms that it is correct, and gives users permission to view it. 

When approval is given, payment rights are activated for each registered customer. Claims for that source will be turned down until that permission is confirmed. Credentialing usually takes between 60 and 90 days for Medicare and 90 to 120 days for private payers, but this depends on how full the application is and how long it takes for the payer to handle it. 

Licensing Process Explained 

Licensing starts during medical school, a long time before credentials. A doctor gets an MD or DO degree from a recognized school, passes the USMLE Step 1, Step 2 CK, and Step 3, and then does the postgraduate residency training that is needed. 

Once these conditions are met, the doctor sends an application for a license to the medical board in the state where they want to work. The Federation Credentials Verification Service is used by most states to check credentials uniformly. They accept the FSMB Uniform Application. On top of the USMLE scores, the application needs proof of medical school and training, a history of failure, and a criminal background check. 

After verifying the original sources and doing a background check, the state board reviews the whole file. The board grants a full, unlimited license upon acceptance. The time it takes to get a license varies by state, ranging from 60 to 180 days. States with a lot of applicants, like California, New York, and Florida, take longer. The license must then be updated according to the state’s rules, which are usually every 1-3 years. Often, ongoing medical education requirements are tied to this. 

Why Both Credentialing and Licensing Are Important in Healthcare 

These two steps keep patients and the business safe, but they do so in different ways. 

The public is protected by licensing, which makes sure that only trained, vetted doctors practice medicine. It is required by state law, and working without a valid license can lead to both criminal and civil penalties. A provider who isn’t qualified or whose license has expired is immediately a legal and liability risk for the business. 

Credentialing helps the business make money and stay in compliance. People who pay for services can’t be billed by providers who don’t have the required credentials. In addition to the lost income, billing for a service that isn’t licensed or whose license has expired puts you at risk of not following the rules set by regulators and payers. 

These two steps work together to give a provider all the authorization they need. Getting a license makes the work legal. Getting credentials makes the work chargeable. Neither one by itself is enough to make a business that is both legal and profitable. 

Common Mistakes in Credentialing and Licensing 

The costliest mistakes in both processes are predictable and preventable. 

Starting the licensing and credentialing processes too late is a common error, often leading to delays in legal practice and billing. 

Instead of waiting until the start date, these steps should begin as soon as a service takes an offer. 

Incomplete applications, like ones that don’t have a CAQH profile or supporting documents can slow down the process and need to be fixed by the candidate themselves. 

Not renewing the due date can have instant effects, such as losing the legal right to practice and having problems with enrolling payers. 

Credentialing and licensing should be done at the same time so that there aren’t too many delays between hiring someone and being able to bill for work. 

How Credentialing and Licensing Work Together 

While licensing and training rely on each other in a certain order, they should be done at the same time. A valid state license is needed for credentialing because payers won’t register a provider without one. However, that doesn’t mean that practice has to wait for one to end before beginning the other. 

Both processes start at the point of onboarding for smooth workflow. The application for a license is sent to the state board while the application for credentials and the CAQH profile are being made at the same time. As soon as the license is issued, the already-completed credentialing applications are sent to the buyers. If you run them one after the other, this method can take weeks or months longer. 

Coordination is harder when the business is in more than one state or uses telehealth. Each state has its own license requirements, and each licensee lets you work with clients in that state. Most practices waste time managing multiple licenses and licensing tracks across multiple states at the same time. This is where professional management makes the most difference. 

How Credex Healthcare Can Help 

Credex Healthcare manages both licensing and credentialing as a single coordinated pipeline. The licensing team oversees state board applications, manages FCVS profiles, files IMLC compacts for providers in more than one state, and keeps track of renewals. The credentialing team is in charge of original source verification, CAQH management, multi-payer enrolment, and the processes for recredentialing. 

Credex Healthcare manages both functions at the same time, so they run them at the same time instead of one after the other. They start running them at the time of hiring to shorten the time between accepting an offer and becoming a paid provider. This teamwork closes gaps where a provider is on the salary but can’t yet practice or bill for practices that are moving into new states or adding more than one provider. Paired with medical billing services, Credex Healthcare assigns practices a single accountable partner for the full path from licensing through reimbursement. 

Conclusion 

Credentialing and licensing are not the same thing, and a business that treats them as if they will pay for it in lost income or legal risks over time will pay. Getting a state license is the proper way to practice medicine. Credentialing is the permission that the insurance company gives to bill them. Every service needs both. Licensing comes first, and then credentials are added on top of that. The companies that do this well do both steps at the same time, start early, keep an eye on extensions, and treat the whole flow to make money instead of just paperwork. As soon as a service is hired, they should be able to start billing right away if everything goes as planned. If not fixed, the holes cost each service thousands of dollars every month. 

Frequently Asked Questions 

What is the difference between credentialing and licensing? 

Getting a license from a state medical board is the proper way to practice medicine. Getting credentialed is the process of confirming and enrolling in a qualified provider so that they can join insurance networks and bill payers. Licenses make practice legal, and credentials make it possible to get paid for it. 

Do doctors need both credentialing and licensing? 

Yes. You need a license to properly see people, and you need credentials to be able to bill insurance for those services. A service with only a licensee can’t bill insurance companies, and they can’t get credentials until their license is valid. 

Which comes first: credentialing or licensing? 

Get your license first. A valid state license is needed for credentialing because payers won’t register a provider who doesn’t have a license. Both can be completed at the same time, so authentication forms are ready to be sent in as soon as the licensee is issued. 

How long does credentialing take? 

Credentialing usually takes between 60 and 90 days for Medicare and 90 to 120 days for private payers, but this depends on how full the application is and how long it takes for the payer to process it. Applications that aren’t complete can make the process take much longer than that. 

Can you bill without credentialing? 

No. Claims submitted for a provider who is not credentialed with that payer will be denied. If the timely filing window passes during a credentialing gap, that revenue is typically unrecoverable.
