Authorization and/or Supervision: Authorization and supervision for staff who touch ePHI
January 29, 2026 · Ken Armstrong
Auditors ask about authorization and/or supervision early, because the answer tells them how the rest of the program is likely to look. The requirement is 45 CFR 164.308(a)(3)(ii)(A).
What the rule says
Authorization and/or supervision (Addressable). Implement procedures for the authorization and/or supervision of workforce members who work with electronic protected health information or in locations where it might be accessed.
That is the text of 45 CFR 164.308(a)(3)(ii)(A). Read it closely: it describes an outcome to achieve, not a product to buy, which is why two practices of the same size can satisfy it in different ways and both be right.
This is an addressable implementation specification, and addressable does not mean optional. Under 45 CFR 164.306(d)(3) you assess whether the specification is reasonable and appropriate in your environment, and then either implement it or, if implementing it is not reasonable and appropriate, document why and implement an equivalent alternative measure if that is reasonable and appropriate. The documented reasoning is itself part of the requirement, so an undocumented decision to skip it is the finding.
What this looks like in practice
In an assessment, 45 CFR 164.308(a)(3)(ii)(A) is not one question. It resolves into several, and each one is really asking for different evidence. These are among the questions asked about it:
- Does the organization have procedures to authorize and/or supervise the workforce members who work with ePHI or in locations where it might be accessed, or, where it has determined that this safeguard is not reasonable and appropriate, documented that determination and implemented an equivalent alternative measure (45 CFR 164.306(d)(3))?
- Does the organization verify that the people performing maintenance on its systems, vendor technicians included, are authorized, and supervise anyone without the access authorization while they work, or, where it has determined that this safeguard is not reasonable and appropriate, documented that determination and implemented an equivalent alternative measure (45 CFR 164.306(d)(3))?
- Does the organization document its workforce security policies and procedures (§ 164.308(a)(3)), covering how workforce members' access to ePHI is authorized or supervised, cleared and terminated (or the documented § 164.306(d)(3) determination for any it has not adopted), and review them periodically and update them as needed in response to environmental or operational changes affecting the security of ePHI?
Ownership usually sits with the security official, though the evidence is often produced by someone else, which is where the trail breaks. A control that works but has no owner tends to stop working the month the person who quietly maintained it changes roles.
Who this applies to
Every covered entity and every business associate, at any size. 45 CFR 164.306(b) allows flexibility of approach, so a two-provider practice and a hospital system may implement this differently and both comply. What flexibility does not allow is skipping the decision: the smaller the organization, the more the written reasoning carries the weight, because there is no scale of operation to make the control self-evident.
Building it, in order
These steps are one way to meet it, drawn from our question bank. Unless a step names a provision, the Security Rule does not require that particular measure: 45 CFR 164.306(b)(1) lets you use any security measures that allow you to reasonably and appropriately implement the standards and implementation specifications, chosen with the factors in 45 CFR 164.306(b)(2).
The sequence below is the order that produces evidence as a by-product rather than as a separate documentation exercise:
- Define which roles are authorized to access sensitive systems, data, and work areas.
- Document supervision arrangements for workforce members who work where sensitive data can be accessed, including new or temporary staff.
- Review authorizations when roles change.
- Maintain a list of personnel and vendors authorized to perform maintenance on your systems.
- Verify authorization and identity before allowing maintenance work to begin.
- Escort and supervise any maintenance worker who lacks the required system access authorization for the duration of the visit. Where the organization determines this safeguard is not reasonable and appropriate, record that determination and the equivalent alternative measure implemented, as 45 CFR 164.306(d)(3) provides.
Where else this maps
The questions behind 45 CFR 164.308(a)(3)(ii)(A) also map to NIST SP 800-66 Rev. 2 5.1.3, 5.2.1, 5.5.1, which is voluntary guidance rather than law; following it does not by itself establish compliance with any law. That matters for scoping: the same evidence can be written once and referenced from each, rather than rewritten per framework.
Evidence an assessor asks for
For this requirement the evidence types that satisfy it are policy, procedure, and record. The distinction matters more than it looks: a policy states what you intend to do, a procedure states how, and a record proves it happened on a date. Auditors ask for all three, and a practice that has written the first two often has nothing for the third.
Date every document and keep the superseded versions. 45 CFR 164.316(b)(2)(i) requires the documentation 164.316(b)(1) calls for (the Security Rule policies and procedures, and the written record of any action, activity or assessment the Security Rule requires to be documented) to be retained for six years from the date of its creation or the date when it last was in effect, whichever is later, so a policy you replaced two years ago is still part of the record.
Where this usually goes wrong
The most common failure here is treating addressable as optional. A practice decides the specification does not fit, implements nothing, and writes nothing down. At assessment the answer to "why not" is a verbal explanation, which is not evidence. The second most common failure is the opposite: implementing an alternative that works, and still not recording the reasoning, so the control looks accidental.
What to do about it
- Produce the evidence, not the intention. For 45 CFR 164.308(a)(3)(ii)(A) that means a signed, dated policy with a named owner and a review date, a step-by-step procedure someone unfamiliar with the task could follow, and dated records of each occurrence, not a description of the process. If the only evidence is that someone knows how this works, you have a practice and not a record.
- Put a name on it. Your security official should be recorded as the owner. Where the work is done by someone else, say so in the document: the split between who owns it and who performs it is where the trail usually breaks. A control with no owner stops working the month the person who quietly maintained it changes roles, and nobody notices.
- Re-read it when something changes. A new system, a new vendor or a departure is what makes a correct control stale. Tie the review to those events as well as to the calendar, and date the result.
- If you decide not to implement it, write the decision down. Addressable is not optional: under 45 CFR 164.306(d)(3) the documented assessment IS part of the requirement, so an undocumented decision to skip it is the finding, and a working alternative with no recorded reasoning looks accidental.
The practical test for 45 CFR 164.308(a)(3)(ii)(A) is whether someone unfamiliar with your organization could read your documentation and tell what you do, who does it, and when it last happened. If they can, the documentation will hold up; whether the requirement is met is a judgment about what it shows, and your counsel owns that conclusion. If they need you in the room to explain it, it will not.
