The key to Medicaid Redetermination is Current Contact Information

Every year, Medicaid Managed Care Organizations (MCOs) lose millions of members—not because those members are ineligible, but because they can’t be reached to complete the necessary paperwork for Medicaid Redetermination. Think about that: Medicaid members who should stay covered are falling through the cracks simply because their contact information is wrong.

Medicaid redetermination is a race against time. There’s a narrow renewal window, and if your outreach misses the mark, eligible members get disenrolled for administrative reasons.

The unfavorable result? Lost revenue, disrupted care, and frustrated members.

The solution starts with accurate contact information data, especially mobile phone number and email address.

Why Data Quality Is Your Secret Weapon

Your outreach is only as strong as the data behind it. If your lists are outdated, your systems are siloed, and identities aren’t managed, you’re fighting an uphill battle.

Poor contact data leads to:

  • Undeliverable mail
  • Disconnected phone numbers
  • Low email engagement
  • Duplicate or missed outreach

You can fix these problems by refreshing and validating contact data daily and by creating a single, trusted record for every member—so your outreach actually reaches them.

The observed improvement: 50% or more increase in contact rates.

Mobile Phone & Email Address are Key for Increasing Medicaid Contact Rates

Medicaid participants tend to be more transient than other groups, which means their physical mailing address may become outdated quickly. Medicaid members often rely on their mobile phone to communicate, making their cell phone number and email address key contact information to reach them for renewal.

You can call, text, and email members when it’s time for renewal, but you must have their current cell phone number and email address. Recent findings showed that at least 1 in 5 phone numbers were likely no longer valid. DDG provides cell phone and email address data that is refreshed daily, so you get the most current contact information at any given point.

What is the Impact of Increased Contact Rates?

Illustration with just a 10% increase:

  • 100,000 members up for redetermination
  • 10% avoidable disenrollment due to unreachable members
  • $6,000 annual value per member
  • $60 million in revenue loss

The Foundation for Redetermination Success

These five aspects are the foundational elements to successful Medicaid Redetermination outreach:

  1. Continuously refreshed mobile phone, email, and address data
  2. Identity resolution at the person and household level
  3. Enrollment-ready records for digital and direct mail outreach
  4. Analytics that prioritize high-risk and hard-to-reach members
  5. An AI-ready, unified source of truth across enrollment, marketing, and operations

The Bottom Line

You can’t requalify members you can’t reach. And to reach them, you need accurate data 365 days a year.

Data quality drives contact rates. Contact rates drive redetermination success. Redetermination success protects revenue.
