Provider Credentialing
Everything you need to get credentialed with insurance companies, from your first NPI registration through re-credentialing. Guides, tools, and checklists for every major payer across all 50 states.
What is provider credentialing?
Provider credentialing is the process by which a payer verifies that a healthcare provider is qualified and safe to practice — confirming license, education, training, work history, and sanctions through primary source verification. It is the step that answers “are you qualified?” — distinct from paneling (will the payer accept you into its network?) and payer enrollment (can you actually get paid?). Confusing the three is the most common preventable cause of lost revenue.
New here? Start with credentialing vs paneling vs payer enrollment — it explains how the three steps fit together and why the gap between them is expensive.
The credentialing process, in depth
Credentialing is the verification stage: the payer confirms, through primary source verification, that you are who you say you are and are eligible to deliver care. It is distinct from paneling and from payer enrollment — see how the three differ.
What gets verified
State license(s), DEA, education and training, board certification, work history, malpractice coverage, and exclusion screening (OIG/SAM) plus NPDB — each confirmed with the issuing source, not just your application.
Timeline by payer type
Medicare via PECOS is often 45–65 days; commercial payers 60–120 days; Medicaid 30–180 days by state. A complete, attested CAQH profile is the single biggest accelerator.
Where it fails
Stale or incomplete CAQH, mismatched license numbers or dates, unexplained work-history gaps, and applying before documents are gathered — all preventable.
What it does not cover
Being credentialed does not mean you can bill. A closed panel can still refuse you, and you cannot submit claims until enrollment sets your effective date.
Billing before your enrollment effective date is the most common preventable revenue loss in this process — on Medicare it returns denial CO-B7. Specialty paths differ too: start with behavioral health credentialing if you are an LCSW, LPC, LMFT or psychologist. Comparing vendors or in-house vs outsourced?
