PECOS 2.0: What’s Actually Different for DME Suppliers in 2026

PECOS 2.0 has been rolling out in phases since late 2025, with every Medicare-enrolled provider scheduled to be migrated by the end of 2026. The forms haven’t changed. A DMEPOS supplier still files a CMS-855S, the application fee still sits at $750, and the standard revalidation cycle for DME suppliers is still every three years. What’s different is what happens the moment something in your record doesn’t line up, and how fast the consequence lands.

The old system forgave inconsistencies. This one doesn’t.

Under the previous version of PECOS, a mismatch between what was on file and what a supplier submitted, an old address, an ownership detail that hadn’t been updated, would typically surface later, during a manual review or a revalidation cycle. There was time to catch it and fix it. PECOS 2.0 runs real-time validation against the data it already holds, and when it finds a discrepancy, it doesn’t wait for the next review cycle to act on it.

What a “Stay of Enrollment” actually means

PECOS 2.0 calls this a Stay of Enrollment: a payment freeze the system applies automatically when its real-time validation flags a discrepancy. The provider stays technically enrolled, the NPI still exists, the PTAN is still active, but claims stop being paid while the discrepancy sits unresolved. An unexpected payment freeze triggered by something as small as an unreconciled address change can create a real cash flow gap with very little warning.

What actually changed, at a glance

It’s arriving alongside tighter documentation requirements

On January 13, 2026, CMS added eight oxygen HCPCS codes to the Face-to-Face Encounter and Written Order Prior to Delivery list (now 83 items), and seven more to the Required Prior Authorization list (now 74), effective nationwide April 13, 2026. CMS is tightening the connection between documentation accuracy and whether a claim, or an enrollment, stays valid.

What to do before your migration notice arrives

• Reconcile ownership and location data now, before PECOS 2.0 validates it for you.
• Confirm every address, license, and accreditation record matches what’s currently on file with CMS.
• Don’t wait for the migration notice to audit your own record.
• Build a standing process, not a one-time cleanup.
