HIPAA164.308 — Information Access Management

§164.308(a)(4)

Information Access Management

HIPAA · 45 CFR Part 164 · Last verified August 2026

Objective

Implement policies and procedures for authorizing access to ePHI consistently with the Privacy Rule and operational responsibilities.

Points of focus

  • Define access authorization by role and need
  • Establish, document, review, and modify access
  • Separate access to healthcare operations from unrelated functions

Implementation notes

Model tenant, support, engineering, and service access separately; require scoped approval for ePHI privileges, expire temporary elevation, and review human plus workload identities from authoritative exports. Operationalize define access authorization by role and need in ticketing, IdP, or GRC workflows with named owners — not only in a static policy PDF. Retain ephi role matrix and approved access requests with reviewer identity, population scope, dates, and remediation outcomes auditors can sample. A recurring failure mode is that customer support receives blanket tenant access when only a narrow troubleshooting role is needed Revisit after material architecture, vendor, data-flow, or leadership changes and document the decision.

Audit tip: Sample ephi role matrix and approved access requests with dates and named reviewers. Be ready to walk through how you detect and correct: customer support receives blanket tenant access when only a narrow troubleshooting role is needed

Evidence auditors typically request:

  • ePHI role matrix and approved access requests
  • Periodic access recertification with remediation
  • Privileged and support-access workflow records

Common gaps

  • Customer support receives blanket tenant access when only a narrow troubleshooting role is needed
  • Access reviews omit service accounts and emergency identities

Frequently Asked Questions

Information Access Management applies to the systems and commitments in your Security Rule scope. Translate the requirement into concrete operating workflows — define access authorization by role and need — with evidence stored where auditors and customers can sample it.

Lead with ephi role matrix and approved access requests and pair it with periodic access recertification with remediation. Samples should show who performed the control, when, against which population, and what changed as a result.

Teams often fail because customer support receives blanket tenant access when only a narrow troubleshooting role is needed Close the loop with dated operating records and test the control on a realistic production path.

Control operation can often be shared across SOC 2, ISO 27001, GDPR, and HIPAA — but each framework uses different vocabulary and accountability. Maintain an explicit crosswalk rather than assuming equivalence.

Review at least annually and after material product, vendor, or data-flow changes. High-risk or privileged paths may need quarterly sampling even when the criterion does not prescribe a cadence.
