Verified steps
Register as a Responsible Reporting Entity (RRE) on the Section 111 Coordination of Benefits Secure Website (COBSW).
Have the RRE's Authorized Representative review, sign, and return the RRE profile report to the Benefits Coordination & Recovery Center (BCRC).
Test Claim Input Files in the RRE's assigned test environment before any production submission; production access is only granted after tests pass.
Submit production Claim Input Files during the RRE's assigned quarterly submission timeframe using an approved transmission method (e.g., SFTP/EFT/Connect:Direct, or HTTPS for smaller files).
Optionally submit a Query File (X12 270/271 eligibility transaction) to check a claimant's Medicare status, using CMS's HIPAA Eligibility Wrapper software or your own X12 translator.
Monitor the current NGHP User Guide version and any published NGHP Alerts, since alerts can supersede guide instructions between full version releases.
Known gotchas
NGHP reporting covers liability insurance (including self-insurance), no-fault insurance, and workers' compensation — it is broader than "liability settlements" alone, and is a separate track from Group Health Plan (GHP) Section 111 reporting, which has its own user guide.
Skipping the test phase is not permitted; production files are rejected until an RRE ID passes testing.
The NGHP User Guide version in effect changes periodically (v8.4, dated April 13, 2026, was current at time of writing) — confirm you're building against the current version, not a cached copy.
