Multiplex LLC — Effective March 23, 2026 — Last updated March 23, 2026

This Business Associate Agreement (BAA) is available to NODEX Enterprise plan subscribers. It governs the use of NODEX for communications involving Protected Health Information (PHI) as defined under HIPAA. By activating the HIPAA controls on your Enterprise account, you agree to the terms of this BAA.

1. Definitions

The following terms have the meanings set forth below. Terms not defined here have the meanings set forth in HIPAA and its implementing regulations (45 CFR Parts 160 and 164).

2. Obligations of Business Associate

2a. Permitted Uses and Disclosures

Multiplex LLC agrees to use or disclose PHI only as permitted or required by this BAA or as required by law. Multiplex LLC will not use or disclose PHI in a manner that would violate HIPAA if done by the Covered Entity.

2b. Safeguards

Multiplex LLC agrees to use appropriate safeguards and, where applicable, comply with the HIPAA Security Rule (45 CFR Part 164, Subpart C), to prevent the unauthorized use or disclosure of PHI. This includes:

2c. Subcontractors

Multiplex LLC will obtain satisfactory assurances, in the form of a written agreement, from any subcontractor that creates, receives, maintains, or transmits PHI on behalf of Multiplex LLC, that the subcontractor will comply with the applicable requirements of HIPAA. Current subcontractors with access to infrastructure that may process ePHI include Supabase (database) and Netlify (hosting).

2d. Reporting

Multiplex LLC agrees to report to the Covered Entity any use or disclosure of PHI not provided for by this BAA, any Security Incident of which it becomes aware, and any Breach of Unsecured PHI as required by 45 CFR 164.410, without unreasonable delay and in no case later than 60 calendar days after discovery.

2e. Access and Amendment

To the extent Multiplex LLC maintains PHI in a Designated Record Set, Multiplex LLC agrees to make PHI available to the Covered Entity to fulfill the Covered Entity's obligations to provide individuals access to their PHI under 45 CFR 164.524. Multiplex LLC agrees to make PHI available for amendment and to incorporate any amendments to PHI per 45 CFR 164.526.

2f. Accounting of Disclosures

Multiplex LLC agrees to document and make available to the Covered Entity information required for the Covered Entity to respond to an individual's request for an accounting of disclosures of PHI per 45 CFR 164.528.

2g. Minimum Necessary

Multiplex LLC agrees to use, disclose, and request only the minimum amount of PHI necessary to accomplish the intended purpose of the use, disclosure, or request, per 45 CFR 164.502(b).

3. Obligations of Covered Entity

The Covered Entity agrees to:

4. Term and Termination

4a. Term

This BAA is effective as of the date the Covered Entity activates HIPAA controls on their Enterprise NODEX account and remains in effect until the Enterprise subscription is terminated or the BAA is otherwise terminated per this section.

4b. Termination for Cause

Either party may terminate this BAA if it determines that the other party has violated a material term of this BAA and has failed to cure the violation within 30 days of written notice. If termination is not feasible, the aggrieved party must report the violation to the Secretary of the Department of Health and Human Services.

4c. Effect of Termination

Upon termination of this BAA for any reason, Multiplex LLC agrees to return or destroy, if feasible, all PHI received from or created on behalf of the Covered Entity. If return or destruction is not feasible, Multiplex LLC agrees to extend the protections of this BAA to such PHI and to limit further uses and disclosures to those purposes that make return or destruction infeasible.

5. Miscellaneous

5a. Regulatory References

Any reference in this BAA to a section of HIPAA means the section as in effect or amended at the time of the relevant obligation, including all regulations promulgated thereunder.

5b. Amendment

Multiplex LLC may amend this BAA as necessary to comply with changes in HIPAA or other applicable law. Multiplex LLC will provide notice to Enterprise subscribers of material amendments. Continued use of NODEX after the effective date of an amendment constitutes acceptance.

5c. Survival

The obligations of Multiplex LLC under Section 4c (Effect of Termination) shall survive the termination of this BAA.

5d. Interpretation

This BAA shall be interpreted as broadly as necessary to implement and comply with HIPAA. Any ambiguity shall be resolved in favor of a meaning that permits the Covered Entity to comply with HIPAA.
