CMS Compliance Requirement
All Health Net Medicare Advantage (MA) participating providers (also referred to as first-tier or downstream entities) who use offshore subcontractors to process, handle or access Health Net MA member protected health information (PHI) in oral, written or electronic form, must submit specific subcontracting information to Health Net. Health Net requires that participating providers submit the following items:
Providers must submit this information for each offshore subcontractor they have engaged to perform Medicare-related work, regardless of whether the information was already completed for a different plan. This information must be submitted to Health Net within 20 calendar days from the date the contract is signed with the offshore subcontractor or immediately upon knowledge of this requirement if the contract has been signed and is in place. Health Net is required to notify the Centers for Medicare and Medicaid Services (CMS) of its and its participating providers’ offshore subcontractor relationships.
If you have any questions regarding provider offshore subcontracting or to obtain a hard-copy of the attestation form, contact the Health Net Provider Services Center by email, through the Health Net provider website, or by telephone at
