Set up electronic transactions

Resubmitting claims

You do not need to resubmit claims for G9919 and G9920 even if you have not received payment or either code was denied for participating physician group (PPG) risk. The medical plan is reviewing past claims to make retroactive adjustments for payments that may be due. 

Employed or independent clinicians

All impacted providers rendering ACEs specific services must ensure they individually take the state certified training and attest. This applies whether you are an employed or an independent provider. 

Note: The June 30 due date for state certified attestations are at the provider level and not the facility level.

Part of a PPG

If you are contracted with a participating physician group (PPG), continue to send claims to the PPG as normal except for ACEs codes G9919 and G9920. Both ACEs codes must be billed directly to the health plan. 

Reminders for time-sensitive due dates

Complete state mandatory certified training by end of June 2020 

To screen patients for ACEs, providers must complete a two-hour online training that focuses on trauma-informed care, the use of the ACEs questionnaire and the age-appropriate screening tool. Register for the training at

All of the certified ACEs training is validated by the state and the Department of Health Care Services (DHCS). DHCS will set up a website and make reports available which list who completed their certified ACEs training. 

Self-attest by July 1, 2020

For continued reimbursement after July 1, 2020, providers must self-attest to DHCS by completing the Trauma Screening Training Attestation form.
