Network Adequacy Monitoring After Your CMS Submission: What Plans Are Required to Do

The Common Misconception About Adequacy

Many health plan network operations teams treat network adequacy as an annual event — a filing that happens in the spring and is forgotten until the following year. This framing is incorrect, and CMS has become increasingly explicit about it. Network adequacy is a continuous obligation, not a point-in-time certification.

The CMS Medicare Advantage regulations require that plans maintain adequate networks throughout the contract year, not just at the time of initial certification. Plans must monitor their networks for changes that would affect adequacy — provider departures, practice relocations, capacity restrictions, and county reclassifications — and respond to those changes proactively.

What CMS Requires for Ongoing Monitoring

The specific monitoring requirements under 42 CFR 422.116 include:

• Maintaining accurate and current provider directories that reflect actual network participation status
• Notifying CMS of material changes to the network that would affect the accuracy of the certified adequacy submission
• Conducting periodic internal adequacy reviews to confirm that the network continues to meet CMS standards throughout the contract year
• Ensuring that providers listed as in-network are actually accepting new patients and providing services

CMS has enforcement authority to conduct secret-shopper surveys and independent provider directory audits at any point during the contract year — not only at submission time. Plans that maintain inadequate networks mid-year but "fix" them before submission are increasingly at risk as CMS expands its mid-year audit activities.

The Provider Departure Problem

The most common source of mid-year adequacy degradation is provider departure. When a contracted provider terminates their participation in the network — whether due to retirement, practice acquisition, relocation, or contract expiration — the counties they served may drop below the adequacy threshold if they were the sole or primary in-network provider of their specialty in that county.

Plans should have a documented process for:

• Receiving timely notification from their credentialing and contracting teams when a provider terminates
• Automatically flagging the counties served by the departing provider for adequacy re-analysis
• Initiating recruitment activity in affected counties before the departure becomes effective

Blueprint's pipeline integrates directly with provider status tracking: when a provider's contract status changes, the adequacy scoring engine recalculates immediately, and counties that fall below threshold trigger an alert to the assigned network development team member.

Quarterly Internal Reviews: Best Practice

High-performing network ops teams conduct formal quarterly adequacy reviews rather than relying solely on real-time monitoring. A quarterly review involves:

• Running a full county-by-county adequacy analysis against current contracted providers
• Comparing results to the certified submission to identify degradation
• Prioritizing recruitment activity for counties approaching or below threshold
• Documenting the review results as evidence of ongoing compliance monitoring

This documentation serves two purposes: it demonstrates to CMS that the plan is actively monitoring (which is itself a compliance requirement), and it creates a contemporaneous record that can support the plan's defense if a CMS audit identifies a transient gap.

Star Ratings and Mid-Year Adequacy

Beyond the regulatory compliance dimension, mid-year adequacy failures affect member access in ways that surface in Star Ratings. Members who cannot access an in-network specialist because the network has degraded since certification are more likely to delay care, seek care out-of-network, or generate complaints that affect the plan's access-to-care measures. Plans with strong mid-year adequacy monitoring consistently outperform peers on the network access components of the MA Star Rating program.
