Beginning on March 1, 2026, providers contracted with the Health Plan of San Mateo (HPSM) will no longer receive quarterly paper provider directory data attestations in the mail. This means that provider’s office administrators must register for HPSM’s Provider Portal to attest digitally through the new Provider Data Accuracy Tool.
Each quarter, offices will be prompted to review Provider Directory information and attest to no changes or submit updates as needed. These attestations will only be able to be captured digitally, so please register for the portal today.
Here are additional benefits for providers and their offices when they register for the provider portal:
- Available 24/7
- Verify members’ eligibility
- Check claims payment
- Submit prior authorization requests and check request status
- Sign up for and update Electronic Funds Transfer/Electronic Remittance Advice (EFT/ERA)
Please contact [email protected] or 650-616-2106 with any questions.
