NIST CSF 2.0 PR.AA-01 covers identity management. In most assessments the control itself is present and the record proving it is not, which is why this requirement produces findings at organizations that are, in practice, doing the work.
NIST CSF 2.0 PR.AA-01 sets the expectation for identity management. The framework describes the outcome rather than prescribing a technology, so the question is whether your implementation achieves it and whether you can show that it does.
In an assessment, NIST CSF 2.0 PR.AA-01 is not one question. It resolves into several, and each one is really asking for a different artifact:
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.
NIST CSF 2.0 is voluntary rather than binding, and that changes how it should be used. Adopting it does not create a legal obligation, and declining it is not a violation. It earns its place when a customer contract names it, when it gives structure to a program HIPAA describes only in outcomes, or when a recognized practice is worth having on record. Treat it as a way of organizing work you already owe, not as a second regime.
The sequence below is the order that produces evidence as a by-product rather than as a separate documentation exercise:
The same evidence answers more than one framework. The questions behind NIST CSF 2.0 PR.AA-01 also map to ISO 27001 A.5.16, A.5.18, A.8.5; SOC 2 CC6.1, CC6.2, CC6.3; NIST 800-53 AC-2, IA-2, IA-4; CIS v8 5.1, 5.2, 6.8; HITRUST 01.d, 01.e, 01.q; HICP 405(d) 3. That matters for scoping: if you are working toward SOC 2 or an ISO certification alongside HIPAA, this control is one piece of work and several answers, provided the artifact is written once and referenced rather than rewritten per framework.
For a healthcare organization the practical reason to care is the overlap: the same questions carry 45 CFR 164.308(a)(4)(ii)(C), 45 CFR 164.308(a)(5)(ii)(D), and 45 CFR 164.312(a)(2)(i). Work done here is not additional to HIPAA, it is the same work with a second label, and the artifact you produce can be cited against both so long as it is written once and kept in one place.
For this requirement the artifact types that satisfy it are configuration, inventory, and procedure. 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 artifact and keep the superseded versions. No federal rule sets a retention period for a voluntary framework artifact, so this is our recommendation rather than a requirement: keep six years, because that is what HIPAA requires of the documentation this work usually overlaps with (45 CFR 164.316(b)(2)(i) for security documentation, 164.530(j)(2) for privacy), and holding two sets of dates is how the earlier one goes missing.
This requirement carries critical weight in an assessment, which means a gap here tends to surface as a high finding rather than an observation. The usual cause is drift: the control was implemented once, the environment changed, and nothing re-checked it. A dated review on a fixed cadence is cheaper than the remediation.
The recurring lesson with identity management is that documentation is not the paperwork after the control. It is the part an assessor can read, and therefore the part that has to exist.
