CMS's Proposed Ghost Network Rule: What Agents Need to Know (It's Not Final)

CMS's Proposed Ghost Network Rule: What Agents Need to Know (It's Not Final)

October 18, 2026•2 min read

If you've had a client pick a plan because their doctor was "in network," then find out the listing was wrong, you know what a ghost network costs. CMS just proposed a fix. Key word: proposed.

What CMS proposed

On Oct 16, per the CMS press release and fact sheet, the proposed rule would:

  • Require MA plans to verify provider directory information at least every 90 days, starting in contract year 2028.

  • Cap cost sharing at in-network levels for a member who relied on an inaccurate "in-network" directory listing, starting in 2028.

  • Have CMS publicly display directory accuracy scores starting in contract year 2029.

  • Separately, lower the generic drug copay for the lowest-income full dual eligibles from $1 to $0 in 2028.

What it is not

It's not final. It doesn't change anything for 2027 plans or this AEP. A proposed rule goes through public comment, and CMS can change it before it's finalized. Don't tell a client a wrong directory listing is covered at in-network cost today because of this rule.

What to do this AEP

  • Keep verifying the old way. Call the doctor's office and ask about the exact plan by name, not just the carrier.

  • Document it. Note who you talked to and when.

  • Set expectations. If a client asks about "the new directory rule," tell them it's proposed for 2028 and later, not in effect.

  • Watch for the final rule. If it's finalized, accuracy scores could become a plan comparison point starting with 2029 plans.
