26-580 New Claims Editing Requirements for Established Patient Billing and Bundled Codes
Date: 04/24/26
These updates are effective June 30, 2026, to support accurate coding and billing practices and guidelines
We are implementing new claims payment edits, effective
June 30, 2026. These edits reinforce correct use of new versus established patient CPT codes and appropriate reporting of comprehensive (inclusive) procedure codes when applicable.
New vs. established patient billing
Claims submitted with new patient CPT codes will be denied when the member qualifies as an established patient, in accordance with the Centers for Medicare & Medicaid Services (CMS) coding guidance. This edit supports correct CPT coding and claims processing.
Denied claims will display claims system denial code EXw4.
- Applies to: All providers (physicians, practitioners and other providers)
- Lines of business: Marketplace Individual & Family Plans (Ambetter HMO/PPO), Wellcare By Health Net Medicare Advantage HMO
Unbundled treatment codes
If a service is already included in a more comprehensive (inclusive or parent) procedure code, it should not be billed separately. When both are billed, the component code will be denied because it is bundled into the primary service.
This coding edit identifies incorrect coding based on the scenarios outlined below.
- Applies to: Mental health and substance use disorder providers
- Lines of business: Marketplace Individual & Family Plans (Ambetter HMO/PPO), Employer Group HMO/POS/PPO, Wellcare By Health Net Medicare Advantage HMO
Unbundling claims scenarios subject to denial
Claims are evaluated using a seven-calendar-day lookback for the same patient and the same physician, practitioner or other provider.
- Scenario 1: A claim billed with 80305, 80306, 80307, G0480, G0481, G0482 or G0483 will be denied if another claim has already been submitted or paid for G2067, G2068, G2069, G2073, G2074 or G2075 within seven calendar days for the same patient and same physician, practitioner or other provider.
- Scenario 2: A claim billed with G2067, G2068, G2069, G2073, G2074 or G2075 will be denied if another claim has already been submitted or paid for 80305, 80306, 80307, G0480, G0481, G0482 or G0483 within seven calendar days for the same patient and same physician, practitioner or other provider.
How to avoid denials and processing delays
When submitting a claim:
- Confirm the member’s patient status.
- Use established patient CPT codes when applicable.
- Report the inclusive or parent code when one code fully describes the service provided.
- Do not separate bill component services that are integral to the primary procedure. Billing both the comprehensive code and its components may result in denial of the component code.
- Only bill separate services when documentation supports a distinct, separately identifiable service and when allowed under applicable coding guidelines.
