Insight
Payer credentialing generally runs several months from a complete application to an effective date, and the variation between payers is wide. The elapsed time is dominated by primary source verification, which is the payer independently confirming licensure, education, training, board status, work history and malpractice coverage with the issuing bodies rather than accepting the application at face value. That step cannot be accelerated by following up. What can be controlled is everything around it: whether the application was complete on arrival, whether CAQH is attested and current, and whether contracting starts promptly once the credentialing committee approves.
An NPI is obtained if the provider does not already hold one. The CAQH profile is completed and attested, since most commercial payers pull the application data from CAQH rather than accepting a separate packet. The payer application is submitted. The payer performs primary source verification. A credentialing committee reviews and approves. Contracting then establishes participation terms and an effective date. Providers and practices routinely treat committee approval as the finish line, but a provider is not billable until the contract is executed and the effective date has arrived.
Gaps in work history are the most common stall, because unexplained gaps must be resolved before verification can complete and the request for explanation often sits unanswered in an inbox. Expired documents are next — a licence, DEA registration or malpractice certificate that lapses mid-process restarts that verification thread. A CAQH profile that has not been re-attested is treated as stale and can halt an application that otherwise looked complete. Then there are the ordinary failures: an application submitted with a missing signature or an unanswered disclosure question does not enter the queue and does not always generate a notice saying so.
Some payers will backdate an effective date to the application date, which allows claims for services already delivered to be filed. Many will not, and the ones that will often apply conditions. Services delivered before an effective date are generally not payable, and the exposure is proportional to how long the provider has been seeing patients while the application sits. This is why a start date and a credentialing start date should not be the same date — building lead time into hiring is far cheaper than negotiating a retroactive date after the fact.
Credentialing is not one-time. Payers re-credential on a recurring cycle, and CAQH attestation expires and must be renewed regardless of whether anything changed. A missed re-credentialing deadline can terminate participation, which means claims begin denying as out of network for a provider who was in network the week before and whose clinical situation has not changed at all. These lapses are entirely preventable and are usually caused by nothing more than an untracked date.

FAQ
They can practise, but whether those visits are payable by a given payer depends on that payer's policy on retroactive effective dates. Some backdate to the application date, many do not. Treating pre-effective-date services as billable is a common and expensive assumption.
CAQH ProView is a centralised credentialing database most commercial payers draw from, so a provider completes one profile rather than a separate full application per payer. It is not universally required, but for payers that use it an un-attested or outdated profile will stall the application.
Credentialing verifies that the provider is who and what they claim to be — licensure, training, history, coverage. Contracting establishes the commercial relationship: participation, rates and an effective date. Passing credentialing without an executed contract does not make a provider billable.
On a recurring cycle set by each payer, with CAQH attestation renewing on its own schedule in parallel. Because the cycles differ per payer, they are tracked per provider per payer rather than as a single annual task.
