June 4, 2026

We are implementing an important update to our claim submission requirements.

Effective July 1, 2026, the billing address entered on the CMS-1500 form in Box 33 and submitted electronically in Loop 2010AA must be a valid physical street address. Post Office Box and Lock Box addresses will no longer be accepted as a valid billing address. Claims that do not include a physical street address in the required field will be rejected at the front end and will not be processed.

Providers should ensure their billing systems and clearinghouse submissions reflect a complete physical street address to avoid claim rejections. To minimize disruption, we encourage you to review your current billing practices and make any necessary updates in advance of the July 1st implementation. If you have any questions, please call our Provider Services Helpline at 1-888-991-9023.
