We previously shared important updates regarding the Wellcare and Carolina Complete Health (CCH) merger, including an initial effective date of April 1, 2026. That timeline has now changed.

New Effective Date and Key Change

Effective June 4, 2026, Carolina Complete Health, Trillium Physical Health, and Partners Physical Health have transitioned from claims denials to upfront rejections for certain billing and credentialing issues.

This change means claims with errors will now be rejected before processing rather than denied after submission. Providers will need to correct and resubmit any rejected claims.

What Providers Should Do

To reduce the risk of claim rejections, providers should review their billing and credentialing practices carefully. It is essential to confirm that all information in NCTracks is accurate and up to date, including NPI, taxonomy, service location, and enrollment details. Mismatched or outdated information may result in rejected or denied claims.

Providers should also ensure that NPI and taxonomy codes are placed in the correct fields on all claims and align with the Carolina Complete Health Provider Billing Manual (pages 48 through 74). When services are rendered at a location different from the billing address listed in field 33, boxes 32, 32a, and 32b must be completed as outlined on page 58 of the manual.

Common Reasons for Rejections

Most upfront rejections are related to NPI status, taxonomy alignment, or missing provider information. Common issues include inactive or unrecognized NPIs, missing or invalid taxonomy codes, and discrepancies between credentialing records and submitted claims.

Errors may involve multiple provider roles, including attending, billing, rendering, referring, supervising, and service facility providers. Rejections can also occur when required provider information is missing, not active for the date of service, or not properly linked within NCTracks.

In some cases, claims may be rejected when a rendering provider is required but not submitted for certain billing taxonomies, or when supervising or service facility provider information is incomplete or not found on file.

Why This Matters

Because claims are now rejected before processing, providers may experience delays in reimbursement if errors are not addressed promptly. This shift increases the importance of accurate credentialing data and correct claim submission.

Taking time now to verify NCTracks information and billing practices can help minimize disruptions and reduce administrative burden.

Key Takeaways

• New effective date: June 4, 2026
• Claims are now rejected upfront instead of denied later
• Most issues involve NPI or taxonomy mismatches
