Medicare (via MACs) — EDI Basics for PT/OT/SLP

At a glance

• EDI enrollments are MAC‑specific; confirm your MAC’s portal/process
• 837P for claims; 835 for remits/ERA
• Direct connections often available after setup; clearinghouse routes remain a fallback

Common setup pitfalls

• Mismatched TIN/NPI/addresses between enrollments and claims
• ERA not linked correctly to claim submitter/receiver IDs
• Missing secondary/tertiary handling configuration
