Part 2 unused treatment-diagnosis coverage

Editorial approval scope: The team checked current source fidelity, scope boundaries, dates, arithmetic, reader usefulness, practical workflow, and general-information limitations.

Current rule checkpoint

The live diagnosis explanation in 42 CFR 2.12(e)(4) covers an identifying diagnosis initially prepared by a Part 2 program in connection with treatment or referral for treatment of a patient with an SUD. A diagnosis prepared for treatment or referral remains covered even when it is not used for that purpose. eCFR displays the section as current through August 20, 2026 and last amended August 13, 2026. The HHS fact sheet confirms the February 16, 2026 compliance date for the 2024 amendments.

Creation purpose controls the example

Current 42 CFR 2.12 expressly covers the unused diagnosis scenario. Record who prepared the diagnosis, program and federal-assistance status, patient, clinical purpose, intended treatment or referral, date, source information, repository, and final disposition.

Disposition does not erase provenance

A canceled admission, declined referral, changed diagnosis, duplicate assessment, waitlist closure, transfer, or later contrary finding can leave the original record within its governing rules. Preserve authorship, time, status, correction history, and access.

Clinical and privacy meanings stay separate

A covered record is not automatically a current diagnosis, final clinical conclusion, medical-necessity finding, authorization, or billing instruction. Qualified clinicians interpret clinical validity; privacy owners determine record handling within applicable law.

Reconstruct the purpose at creation

Record the preparing clinician or other qualified author, Part 2 program, federal-assistance status, patient, source information, encounter, clinical question, intended treatment or referral, date, system, and disposition. Use contemporaneous orders, assessment plans, referral records, workflow state, and authorship rather than a later label alone.

An admission may be canceled, a referral declined, a diagnosis revised, a patient transferred, or the information left in draft. Those later events do not change why the diagnosis was initially prepared. Preserve the original state and every dated correction or supplement.

Keep coverage and clinical status separate

A covered diagnosis may be provisional, disputed, superseded, entered in error, or never used. Privacy classification does not make it a current clinical conclusion. Clinical validity does not decide whether the original identifying record retains Part 2 protection.

Give qualified clinicians a correction and patient-amendment route. Keep original authorship, source, date, status, rationale, notification, and downstream correction evidence. Prevent billing, payer, scheduling, treatment, or analytics systems from treating an unused or superseded diagnosis as current without clinical support.

Control dormant and abandoned workflows

Inventory drafts, waitlists, canceled admissions, uncompleted assessments, referral queues, temporary files, scans, messages, downloads, and vendor copies. Apply access, consent and disclosure, notice, retention, deletion, incident, and legal-demand rules according to the supported classification.

Reassess after migration, duplicate cleanup, patient matching, program closure, or repository consolidation. Do not erase provenance by converting every old status to “inactive.”

Example

Twelve diagnosis records are reviewed. Nine have program, creator, treatment or referral purpose, date, patient, status, and disposition evidence; three show only a diagnosis label. Completeness is 9 of 12 records.

Record coverage and clinical status separately

For each record, assign one privacy outcome: covered under the unused-diagnosis rule, supported outside that example, or unresolved. Separately record clinical status such as draft, provisional, superseded, corrected, disputed, or final. Cite author, purpose, program, patient, dates, evidence, reviewer, and next action.

Use an interim access and disclosure restriction for unresolved records. Do not delete or downgrade them merely to simplify the queue. Preserve source material and prevent automated tools from treating an uncertain classification as permission.

Verify the outcome in patient access, treatment exchange, payer response, legal request, retention, and analytics. Confirm that the released view represents clinical status accurately while following the privacy decision.

For a correction, identify downstream recipients and systems, communicate the supported update, preserve the original and reason, and document completion. Recheck after migration or program closure because inactive workflows often lose purpose and authorship evidence.

Unused-diagnosis checklist

• identify author, program, assistance, patient, source, purpose, date, and repository;
• preserve evidence that the diagnosis was prepared for treatment or referral;
• keep privacy coverage separate from current clinical validity and operational use;
• retain original entries, corrections, authorship, status, and downstream notifications;
• inventory drafts, canceled workflows, queues, exports, vendors, and copies; and
• test access, release, legal-demand, retention, and migration behavior.

This rule does not decide whether a diagnosis is clinically correct, current, billable, or actionable. The original purpose, program facts, identifying content, current Part 2, state law, and proposed use require qualified clinical, privacy, and legal review.
