What health plans need to know and do before the Phase 2 of the new ACH requirements take effect. A focused roadmap to implement fraud monitoring, update descriptors and align vendors before the deadline.
Phase 2 of Nacha’s 2026 rule updates is approaching, and the execution window for health plans is short. The mandate is clear: implement risk‑based fraud monitoring across ACH transactions and standardize specific entry descriptions. If your organization hasn’t already made updates, now is the time to get ready.
This roadmap distills the work into a 90‑day sprint to prioritize high‑impact controls, system changes and vendor alignment to minimize disruption and reduce fraud risk.

What Health Plans and Payers Need to Know
Nacha’s new rules are designed to make these payments safer, and require organizations to:
- Watch for unusual or suspicious payment activity (fraud monitoring)
- Use specific descriptions for certain types of payments (so banks and recipients know what the payment is for)
- Review their payment processes regularly to make sure they’re working
If your health plan doesn’t follow these rules, you could face fines, lose the ability to send payments electronically or experience payment delays.
What to Tell Stakeholders at Your Health Plan
- Nacha’s new rules are about protecting our payments and keeping us in good standing with banks.
- We need to update how we monitor payments and describe them in our systems.
- There’s a clear plan to follow, and we have about 90 days to get it done.
- If we don’t, we risk fines, payment delays, or losing the ability to pay providers electronically.
A 90-Day Roadmap
Here’s a step-by-step plan to share at your health plan:
Days 1-15: Get Organized
- Make a list of all the ways your health plan uses ACH payments (paying providers, collecting premiums, refunds paying vendors).
- Find out who handles these payments in your organization.
- Talk to your bank and any payment vendors to learn what changes are needed and when.
Days 16-45: Build Your Controls
- Set up ways to spot unusual payment activity (like payments to new accounts or amounts that don’t match your usual patterns).
- Make sure any changes to payment instructions (like a provider asking to change their bank account) require extra checks—such as a phone call to a known contact or approval from two people.
- Update your payment systems to use Nacha’s required descriptions (like “PAYROLL” for wage payments or “PURCHASE” for online premium payments).
Days 46-75: Test and Train
- Test your new processes with your bank or payment vendor to make sure everything works.
- Ask your vendors to confirm they’re making the same updates.
- Train your staff on the new steps, especially those who handle payments or provider requests.
Days 76-90: Final Checks and Go Live
- Run a practice audit to see if your new controls catch mistakes or fraud.
- Make sure your team knows what to do if something looks suspicious.
- Start using the new processes for real payments.
- Keep an eye on things and adjust as needed.
You don’t need to be an ACH expert to help your health plan get ready. By following this simple roadmap, you’ll help your team stay secure, compliant and ready for Nacha’s new requirements.
