In 2026, provider network directory accuracy is no longer a “compliance checkbox.” It has become a defining expectation across commercial, marketplace, and government-sponsored healthcare. Driven by a convergence of federal mandates, CMS transparency initiatives, and increasingly aggressive state enforcement, payers face heightened accountability for ensuring that provider information is accurate, timely, and verifiable.
As oversight grows stricter, health plans must treat directory validation as a continuous operational priority instead of a periodic clean-up effort. Here is what is shaping the landscape in 2026 and how payers can stay ahead.
Commercial and Marketplace Plans: Convergence of Transparency and Enforcement
For marketplace and commercial lines of business, 2026 marks a period of increasing alignment between the No Surprises Act (NSA) requirements and broader CMS transparency rules. These federal expectations are being reinforced, and in many cases surpassed, by state-level laws and regulatory audits.
Across the country, states are tightening standards around:
-
Provider availability and accessibility reporting
-
Directory accuracy audits
-
Timeliness of updates for provider changes
-
Network adequacy enforcement tied directly to directory data
This layered regulatory environment means payers must meet national baselines as well as also evolving local requirements that can differ significantly by market.
In short, directory validation is becoming more standardized federally while also being more aggressively enforced at the state level.
The NSA Baseline: A New Operational Minimum
The No Surprises Act positioned directory accuracy as a key consumer protection requirement with real implications for member access and cost. As we enter 2026, NSA rules are firmly embedded as the baseline expectation for network management.
Key NSA directory requirements include:
-
90-Day Verification Cycles: Plans must verify provider directory information at least every 90 days, ensuring that data stays current rather than aging over time.
-
Rapid Provider Update Deadlines: When providers submit changes, such as new locations, status updates, or contact corrections, plans are expected to incorporate updates within two business days.
-
One-Day Response Requirement: Health plans must respond within one business day when a member asks whether a provider is in-network.
-
Member Reliance Protections: If a member receives care based on incorrect directory information, plans may be required to treat related claims as in-network, even if the provider was actually out-of-network.
This shifts the burden of directory accuracy squarely onto payers, with financial consequences tied directly to data failures.
Medicare Advantage: Major Transformation Coming by 2027
While commercial plans are facing tightening enforcement today, Medicare Advantage (MA) is heading toward one of the most significant directory reforms yet.
By 2027, CMS is expected to implement a more standardized and centralized approach requiring:
-
Standardized Directory Data Submission: Plans must submit network directory information in a consistent format directly to CMS.
-
30-Day Update Requirement: Directories must be refreshed within 30 days of any provider change, which is a shorter and more demanding window than many plans currently operate under.
-
Annual Accuracy Attestation: Medicare Advantage organizations will need to formally attest each year that their directory data meets accuracy and completeness standards.
-
Public Display in Medicare Plan Finder: Directory data will be published through the Medicare Plan Finder tool, increasing consumer visibility and reputational risk for inaccuracies.
For MA plans, this creates urgency in 2026. The operational foundation built now will determine readiness for 2027 compliance.
