# Choosing a HIPAA-compliant medical records retrieval API

*By Tavrn Team · Published 2026-11-05 · Technology*

Evaluate a HIPAA-compliant medical records retrieval API by checking authorization, business associate terms, access controls, and the records your workflow needs.

A HIPAA-compliant medical records retrieval API needs more than a working connection. For a service acting as a business associate, review its contract and safeguards for protected health information, or PHI. Then check the legal basis for each disclosure and test whether the service can obtain the records your workflow needs. \[1\]\[2\]\[3\]

Start with a map of the data flow. Who sends the request? Who holds the records? Who receives them? Include storage, support tools, and each app that gets a copy. Use that map to guide your security and privacy review.

## Start with the legal basis for retrieval

An API key and a patient's permission do different jobs. The Security Rule requires a way to check who is seeking access to electronic PHI. The Privacy Rule governs how PHI may be used and shared. That includes uses that rely on a valid authorization. \[2\]\[3\]

HIPAA does not require patient authorization for every disclosure. Under 45 CFR 164.508(a), authorization is required except where the rules otherwise permit or require the use or disclosure. Do not assume that a patient-authorized workflow and a treatment workflow use the same legal basis. [\[3\]](https://www.ecfr.gov/current/title-45/section-164.508)

If your workflow relies on authorization, check the form before sending a request. It must describe the information in a meaningful way. It must say who may disclose it, who may receive it, why it is needed, and when the permission ends. It needs a signature and date. The rule also requires statements about the right to revoke, whether services depend on signing, and the risk of further disclosure. It must use plain language. [\[3\]](https://www.ecfr.gov/current/title-45/section-164.508)

Ask the vendor to demonstrate how it handles an incomplete, expired, or revoked authorization. Those are among the defects listed in 45 CFR 164.508(b)(2). Keep a path for human review instead of treating each rejected request as a technical error. [\[3\]](https://www.ecfr.gov/current/title-45/section-164.508)

## Review the business associate relationship

Check whether the vendor acts as your business associate, or as a subcontractor of one. HHS describes a business associate as an entity that does certain work for a covered entity and has access to PHI. Its guidance also covers subcontractors that create, receive, maintain, or transmit PHI for another business associate. [\[1\]](https://www.hhs.gov/hipaa/for-professionals/covered-entities/sample-business-associate-agreement-provisions/index.html)

HHS's business associate contract guidance states: “A business associate may use or disclose protected health information only as permitted or required by its business associate contract or as required by law.” [\[1\]](https://www.hhs.gov/hipaa/for-professionals/covered-entities/sample-business-associate-agreement-provisions/index.html)

Read the proposed agreement with the actual service in mind. HHS's guidance calls for terms that set permitted uses and safeguards. It also covers reporting of uses or disclosures that are not allowed. Other terms govern subcontractors and the return or destruction of PHI when the contract ends, where feasible. Ask who handles an incident and how your team will reach that person. [\[1\]](https://www.hhs.gov/hipaa/for-professionals/covered-entities/sample-business-associate-agreement-provisions/index.html)

Do not leave hosting outside this review. HHS explains that a cloud provider maintaining encrypted electronic PHI may still be a business associate even if it lacks the decryption key. Encryption does not, by itself, remove those obligations. [\[4\]](https://www.hhs.gov/hipaa/for-professionals/special-topics/health-information-technology/cloud-computing/index.html)

## Ask for evidence behind security claims

Review controls across the full data path, not just the API endpoint. Under 45 CFR 164.312, the Security Rule requires controls for access and audits. It also requires safeguards for data integrity, checks on identity, and protection of electronic PHI in transit. [\[2\]](https://www.ecfr.gov/current/title-45/section-164.312)

Use a review checklist that turns each requirement into a concrete question:

| Review area | Question for the vendor | Evidence to request |
| --- | --- | --- |
| Access control | Who can access a request and its files? | Access policy and a demonstration of role boundaries. [\[2\]](https://www.ecfr.gov/current/title-45/section-164.312) |
| Audit controls | Which actions are recorded and examined? | Sample audit records and the review process. [\[2\]](https://www.ecfr.gov/current/title-45/section-164.312) |
| Integrity | How are unauthorized changes detected or prevented? | Documented controls for record handling. [\[2\]](https://www.ecfr.gov/current/title-45/section-164.312) |
| Transmission security | How are records protected while moving between systems? | Data-flow diagram and transport controls. [\[2\]](https://www.ecfr.gov/current/title-45/section-164.312) |
| Risk management | What risks remain, and who owns the response? | Risk assessment scope and mitigation process. [\[5\]](https://www.ecfr.gov/current/title-45/section-164.308) |

This is a starting point, not a full compliance review. Some technical specifications, including encryption, are marked “Addressable” in the cited rule. Ask your security reviewer how the vendor meets the safeguards that apply. Do not treat a feature list as the rule itself. [\[2\]](https://www.ecfr.gov/current/title-45/section-164.312)

Your own app still needs review. The administrative safeguards rule requires covered entities and business associates to assess risks to electronic PHI and take steps to manage them. Include the copies your system stores. Check the logs it writes and the services it calls, too. [\[5\]](https://www.ecfr.gov/current/title-45/section-164.308)

## Separate data format from record coverage

FHIR is a standard for exchanging health information between apps. HL7 describes resources, ways to exchange them, and a framework for extending them. This sets out how data can be represented and exchanged. Test record coverage as a separate question: which records will the service obtain for your use case? [\[6\]](https://hl7.org/fhir/R4/overview.html)

Compare approaches by asking for evidence, not by assuming that a channel name answers the coverage question:

| Approach | What to test before choosing it |
| --- | --- |
| A FHIR-based connection | Which sources, resources, documents, and date ranges are available for your intended use? |
| A provider-request workflow | What does each provider need, and how are missing items or rejected requests handled? |
| A combined workflow | How are results from different sources matched, tracked, and checked for gaps? |

Write down the expected record set before the test. Ask to see records received, requests still open, and requests closed with no records. Agree on what “complete” means for your app. A successful API response should not be your only test.

## Test the lifecycle before production

Use synthetic data to test the connection before you add live records. Try a request that completes, one that needs more information, and one that cannot be filled. Test status changes and repeated notifications. Check how your app handles missing files and denied access. These are suggested engineering checks, not added HIPAA rules.

Tavrn's developer page describes a synthetic-data sandbox. It supports webhooks or polling to track retrieval status. Before live requests, Tavrn reviews the business associate agreement with your team. Use those published steps to plan your test. Sandbox access is not production access. [\[7\]](https://www.tavrn.ai/developers)

For the security review, Tavrn states that records are encrypted at rest and in transit. Its Trust Center holds SOC 2 Type 1 and Type 2 reports and a HIPAA attestation, shared after an access request is approved. Review those materials alongside the proposed agreement and your own data flow. [\[8\]](https://www.tavrn.ai/security)

## What to do next

Bring your intended use, required record types, and data-flow diagram to a [demo](https://www.tavrn.ai/demo). Ask to walk through authorization, vendor duties, request status, and record delivery. Decide on production access only after your engineering, privacy, and security reviewers agree on the evidence they need.

## Does a business associate agreement make an API HIPAA compliant?

A business associate agreement sets permitted uses and duties for a business associate. It does not replace the technical safeguards or risk analysis required by the HIPAA Security Rule. \[1\]\[2\]\[5\]

## Does every medical record retrieval request need patient authorization?

HIPAA permits or requires some disclosures on other grounds. For a workflow that relies on patient authorization, the authorization must meet the applicable requirements of 45 CFR 164.508, and the disclosure must stay within its scope. \[3\]

## Is FHIR the same as a medical record retrieval service?

FHIR is a standard for exchanging health information between applications. When evaluating a retrieval service, separately ask which providers and record types it can obtain and what happens when a source cannot supply the requested records. \[6\]
