A centralized provider data repository most payers use during credentialing. It must be kept current and re-attested regularly.

How often is re-credentialing required?

Typically every 2–3 years depending on the payer. Missing re-credentialing can drop a provider from a network unexpectedly.

Medical Credentialing: Timelines, Process, and How to Speed It Up

By the ABA Editorial Team·Updated June 2026

Quick Answer

Medical credentialing is the process of enrolling healthcare providers with insurance networks so they can bill for services. Credentialing delays of 90 to 150 or more days with major payers mean lost revenue before a single claim is ever submitted, making it one of the most underestimated revenue risks in any practice.

What Is Medical Credentialing?

You can't bill for a provider who isn't credentialed. Every day a provider waits to get in-network is a day of lost revenue — either the practice can't bill that payer at all, or bills out-of-network at dramatically reduced rates. Yet credentialing is often treated as administrative paperwork rather than the revenue-critical process it is.

Credentialing is the verification of a provider's qualifications and their formal enrollment with payer networks. Until it's complete, cash flow from that provider is compromised from day one.

Credentialing Timelines by Payer

Commercial payers: typically 60–120 days
Medicare: typically 60–90 days
Medicaid: varies widely by state, often 90–150+ days

Start early. Credentialing should begin well before a provider's intended start date. For new practice launches or group expansions, 120 days of lead time is a minimum — not a cushion.

Common Causes of Credentialing Delays

Incomplete or inaccurate applications submitted to payers
Missing documentation — licenses, DEA, malpractice certificates
CAQH profile not current or not attested
Slow payer processing with no active follow-up
No tracking system for pending applications

The 5-Step Credentialing Process

Gather all provider documentation and credentials — licenses, board certifications, malpractice history, DEA registration, NPI.
Complete and maintain the CAQH profile. Most commercial payers pull directly from CAQH. An outdated profile stalls every application.
Submit applications to each payer network with complete supporting documentation. Incomplete applications are returned and restart the clock.
Follow up relentlessly on pending applications. Payers do not proactively communicate status. Credentialing without active follow-up is credentialing that stalls.
Track effective dates and re-credentialing deadlines. The work doesn't end at approval — it cycles every 2–3 years.

Managing CAQH and Re-Credentialing

CAQH (Council for Affordable Quality Healthcare) must be kept current and re-attested every 120 days. A CAQH profile that lapses creates delays across every payer that uses it — which is most commercial payers.

Re-credentialing typically happens every 2–3 years. Missing a re-credentialing deadline can drop a provider from a network with no warning, creating a billing gap that's disruptive and avoidable.

When to Outsource Credentialing

Multiple providers, multiple payers, frequent new hires, or a history of credentialing delays all make a dedicated credentialing service worthwhile. The revenue protected — from in-network billing starting on time — typically far exceeds the cost of the service. A credentialing delay of even 30 days for a productive provider costs real money.

Frequently Asked Questions

Typically 60–120 days for commercial payers, 60–90 days for Medicare, and 90–150+ days for Medicaid depending on the state. Start the process at least 90–120 days before a provider's intended start date.

Well before their start date — ideally 90–120 days ahead to account for payer processing delays, document requests, and state-specific Medicaid timelines.

The Council for Affordable Quality Healthcare — a centralized provider data repository most commercial payers use during credentialing. Providers must maintain and re-attest their CAQH profiles every 120 days.

Typically every 2–3 years depending on the payer. Missing a re-credentialing deadline can drop a provider from a network unexpectedly, creating an immediate billing gap.

Consider it with multiple providers, multiple payers, frequent new hires, or a history of delays. The revenue protected from on-time in-network billing typically far exceeds the service cost.
