A newly licensed therapist in any state in the country can begin seeing clients in private practice the day their license is issued. They cannot bill insurance for those sessions until they are credentialed with each individual payer — a process that, depending on the insurer and the state, takes between 90 and 180 days.
During those months, the practitioner is either turning away clients who need insurance coverage, seeing clients and absorbing the billing delay, or not working. The mental health access problem — which every major health policy document identifies as a crisis — is being actively worsened by a credentialing system that was designed by and for the insurers who administer it.
How the system works and why it does not
Credentialing requires a provider to submit documentation of their license, malpractice insurance, education, training, and clinical history to each insurer individually. Each insurer reviews this documentation on its own timeline, using its own criteria, with its own administrative staff.
There is no standardized form. There is no standardized timeline. There is no standardized set of criteria. There is no regulatory requirement that credentialing be completed within any specific period. MedTrainer’s industry summary of CAQH credentialing timelines confirms that the process typically runs three to six months across major commercial insurers.
The CAQH problem
The Council for Affordable Quality Healthcare — CAQH — operates a centralized provider database that was designed to streamline credentialing. Providers submit their information once; insurers query the database rather than requiring individual submissions. CertifyOS has published a detailed overview of how CAQH credentialing works in practice.
In theory, CAQH should have solved this problem. In practice, most insurers use CAQH as a data source but conduct their own parallel review processes anyway. The database reduced paperwork. It did not reduce time. Relias has documented CAQH credentialing benchmarks confirming that provider timelines have not materially improved despite broader CAQH adoption.
Who benefits from the delay
The credentialing delay benefits insurers by delaying when claims begin to be paid for that provider’s clients. For an insurer with many pending credentialing applications at any given time, that delay can generate a financial benefit through retained cash. This is not a conspiracy theory. It is an incentive structure. The people who designed the credentialing system built it in a way that benefits the designers — and that benefit has never been regulated away.
What would actually fix it
A federal standard requiring credentialing completion within 30 days of a complete application, with automatic provisional credentialing at 45 days, would significantly reduce the problem and could eliminate most unnecessary delays. Several states have enacted versions of a 30-day credentialing standard, though the details vary. Federal legislation has been introduced twice in the last six years and has not advanced either time.
A new introduction is expected in the current congressional session, though progress depends on constituent pressure from mental health advocacy organizations overcoming insurance industry opposition.
What to watch
The credentialing reform debate will advance or stall based on whether mental health advocacy organizations can generate the sustained political pressure needed to move it. State-level action remains the more viable near-term path.
