Contract Impact

Review vendor and business associate agreements—especially debt-collection and other vendors handling patient information—for clear security controls, limits on data shared and permitted uses, data segregation, and obligations to report vendor security events promptly. Confirm contracts grant audit and assessment rights, require evidence of ongoing compliance, support incident response and internal escalation, and allow termination for security non-compliance. Review customer-facing privacy notices and employee incident-response procedures for consistency with these vendor oversight commitments.
