Plans that treat network build as a compliance checkbox are about to lose ground to those who see it as a market strategy — here's what separates the two.
The Market Is Compressing — and the Margin for Error Is Gone
Medicare Advantage enrollment hit a new high in 2026, and so did plan exits. The plans leaving markets aren't leaving because members didn't want their product. They're leaving because the economics broke — partly driven by Star Ratings pressure, partly by risk adjustment changes, and in more cases than leadership will admit publicly, by network-related enforcement actions that triggered corrective action plans and member notification requirements.
The 2026 operating environment is not forgiving. CMS has made its posture clear: organizations that cannot demonstrate — in real time, with auditable documentation — that their networks meet access standards will face consequences that are financial, reputational, and operational. That's the baseline. The organizations that thrive in this environment will be the ones that figured out earlier than their competitors that network is a strategic asset, not a compliance artifact.
CMS Is Not Slowing Down on Enforcement
If the last two years taught network leaders anything, it's that CMS's appetite for enforcement is not seasonal. The agency has accelerated its use of intermediate sanctions, civil monetary penalties, and — most disruptively — public corrective action plan disclosures. Plans that were operating on a "we'll fix it before the audit" model have found that the audit cycle no longer gives them that runway.
Three areas are drawing the most scrutiny in 2026:
- Appointment wait-time compliance — CMS is increasingly cross-referencing plan attestations against member grievance data. If your attestation says 15-day wait times and your grievance log says otherwise, that discrepancy is now a finding, not a conversation.
- Provider directory accuracy — The 48-hour update window has real teeth now. Plans with stale NPI data or wrong panel status are receiving deficiency notices at a rate that would have been unthinkable three years ago.
- D-SNP access standards — As dual-eligible enrollment grows, CMS is applying a sharper lens to whether D-SNP networks actually include the behavioral health, LTSS, and social services providers the population needs — not just the ones that look good on paper.
D-SNP Expansion Is a Trap for the Underprepared
D-SNP is the growth story in MA right now. Dual-eligible lives represent a significant revenue opportunity, and plans that have positioned correctly are seeing meaningful enrollment gains. But D-SNP network requirements are materially more demanding than standard MA — and too many plans are discovering that after they've committed to the expansion.
The access standard differences are not cosmetic. D-SNP enrollees require closer specialist access, more robust behavioral health networks, and providers who actually understand the dual-eligible population's clinical complexity. Plans that built their MA network for a standard commercial-adjacent population and then overlaid a D-SNP product on top of it are finding gaps they didn't know they had — usually during an audit.
The plans that are winning D-SNP are the ones that built the network first, then launched the product. The ones that are struggling launched the product and then realized they needed a different network.
The Competitive Frame Has Shifted
Network used to be a differentiator primarily around hospital affiliation — which health system was in-network mattered to brokers and members. That still matters. But in 2026, the competitive frame has expanded. Networks that include integrated care coordinators, telehealth providers with real capacity (not just a contract on file), and behavioral health specialists with open panels are becoming the table stakes for competitive bids in saturated markets.
Plans that are competing in markets with three or more strong MA options are finding that their network breadth, access standards, and provider experience scores are increasingly surfacing in broker conversations. Members now have real choices, and brokers are doing real due diligence. The "good enough" network is no longer good enough.
What Network Leaders Should Be Doing Right Now
This is not a moment for incremental improvement. The organizations that will be in stronger competitive and compliance positions 18 months from now are making deliberate moves today:
- Audit your documentation infrastructure, not just your network. A good network you can't prove is a compliance liability. Do you have real-time attestation workflows, panel status verification, and appointment access monitoring — or are you still relying on annual surveys?
- Map your D-SNP exposure before CMS does it for you. If you have D-SNP products or are planning them, run a gap analysis against actual D-SNP access standards, not MA standards. The delta is larger than most network teams expect.
- Treat rural and frontier counties as a strategy problem, not a credentialing problem. The plans closing rural gaps fastest are the ones using telehealth strategically — with real utilization data — not just as a workaround.
- Build the business case for network investment at the executive level. CFOs need to understand that network enforcement costs — corrective action plans, member notifications, penalties — are far more expensive than proactive investment. Make that math visible before an audit forces the conversation.
Network leaders who are still waiting for the compliance team to flag problems before acting are operating on the wrong timeline. The 2026 landscape rewards plans that see network as infrastructure for growth — and it will punish the ones that don't before the year is out.
