Credentialing Standards

The established criteria and requirements set by accrediting bodies like NCQA, regulatory agencies, and payers that define how the credentialing process must be conducted.

Credentialing standards are the rules that govern how credentialing must be done. They define what must be verified, how it must be verified, how often it must be re-verified, who makes the decisions, and how the process must be documented. Multiple organizations set credentialing standards, and they do not always agree. NCQA sets the most widely recognized credentialing standards for health plans. Their Credentialing and Recredentialing standards specify: which credentials must be primary source verified (license, board certification, education, malpractice history, DEA), the maximum time between verification and committee decision (180 days), the minimum re-credentialing frequency (every 36 months), the requirement for physician participation on the credentialing committee, and documentation requirements for the credentialing file. The Joint Commission sets credentialing standards for hospitals. Their standards cover initial appointment, reappointment, privileging, ongoing professional practice evaluation, focused professional practice evaluation, and peer review. Joint Commission standards are enforced through their accreditation surveys. CMS sets credentialing standards for Medicare participation through the Conditions of Participation and the Conditions for Coverage. These standards apply to hospitals, skilled nursing facilities, home health agencies, and other institutional providers. State regulators add their own requirements. Some states have specific credentialing laws that go beyond NCQA or Joint Commission standards. For example, some states require background checks, fingerprinting, or specific training as part of credentialing. For providers, credentialing standards determine what you need to submit and how your application will be processed. Understanding the applicable standards helps you prepare a complete application and anticipate the verification steps. If a payer asks for something that seems unusual, check whether it is actually required by a standard or if the payer is adding their own layer of requirements. Standards evolve over time. NCQA updates its standards periodically, and payers update their internal requirements to align. Staying current on standard changes helps credentialing professionals maintain compliance and avoid audit findings.
