Transitioning Your Payer Enrollments to ClaimMD: A Step-by-Step Guide

Last updated: March 19, 2026

For practices migrating from SimplePractice or another clearinghouse

When you transition to Osmind and Claim.MD for claims submission and remittance processing, moving your existing payer enrollments smoothly is critical to maintaining cash flow. This guide walks you through the process, avoiding common pitfalls like timely filing issues and ERA delivery failures.

The Core Challenge

Your old clearinghouse won't automatically know to stop routing your ERAs (remittance advice), and the new payer setup won't happen overnight. Without a structured plan, you risk claims getting stuck between systems or ERAs landing in the wrong place. The good news? This is entirely manageable with the right workflow.

Step 1: Submit Your Claim.MD Account Request Form

Before you do anything else, complete the enrollment form here: Claim.MD Account Request Form

This kicks off the account configuration on our end and ensures your organization is properly set up in Claim.MD. Don't skip this step.

Step 2: Consolidate Your Payer List

Once your Claim.MD account is ready, create a list of your payers.

Follow the Claim.MD steps for enrolling providers and payers.

Step 3: Keep Parallel Claims Active During Approvals

Phase 1 (Weeks 1–4, while approvals are in flight):

  • Route all claims through your old clearinghouse

  • This is your safety net while Claim.MD enrollments are pending

Phase 2 (Once a payer approval lands):

  • Set a hard cutoff date in your billing software for that specific payer

  • Example: "All Anthem claims submitted after [date] route to Claim.MD"

  • Going forward, only new claims for that payer go to Claim.MD

Critical: Never split claims for the same payer between two clearinghouses on the same submission date. This creates duplicates, lost claims, and reconciliation nightmares.

Step 4: Understand the Clearinghouse Handoff (The Good News)

Here's what actually happens when your Claim.MD enrollment is approved:

  1. Claim.MD submits to the payer with updated clearinghouse routing information

  2. The payer automatically re-points ERA delivery to Claim.MD's clearinghouse

  3. Your old clearinghouse naturally stops receiving ERAs once the payer processes the change

You don't need to manually notify your old clearinghouse for each payer, this happens automatically.

Step 5: Validate the Transition (Your Responsibility)

After you cut over each payer, take these steps:

1. Confirm ERA delivery is working in Claim.MD

  • Submit 1–2 claim cycles for that payer

  • Verify ERAs are arriving and matching to claims correctly

  • Don't consider the transition complete until this is confirmed

2. Run a reconciliation

  • Identify any in-flight claims that were submitted in your old clearinghouse before the cutover

  • These will continue generating ERAs for 30–45 days post-submission, and these ERAs may flow into Claim.MD as un-postable (e.g. there is no claim to post against)

  • Track them so you don't miss late payments

3. Keep old clearinghouse access live temporarily

  • Don't close your old clearinghouse account immediately

  • Maintain read-only access for 60+ days

  • Use it to retrieve any stranded ERAs during the transition window

Recommended Workflow: Start-to-Finish

  1. Submit the Claim.MD account request form above

  2. Pull your payer list

  3. Submit Claim.MD enrollments

  4. Track approval dates in a simple spreadsheet

  5. Set a cutoff date in your billing software for each payer once approved

  6. After cutover: Validate ERA receipt in Claim.MD for 1–2 cycles

  7. Run reconciliation on in-flight claims

  8. Monitor your old clearinghouse for stragglers during the 30–45 day window

  9. Once all payers are stabilized, close the old clearinghouse

Bottom Line

A smooth transition happens when you:

  • Keep parallel claim flows active during approval periods

  • Validate ERA delivery before considering each payer fully migrated

  • Track in-flight claims to catch any stranded ERAs

Most cash flow issues occur when practices try to rush the process or assume the old clearinghouse will automatically stop. It won't. A structured approach takes a few extra weeks but prevents expensive mistakes.
