The Eighteen Foundational Postulates
Postulate 16 Revision Principle
Statement
A medical diagnostic assessment SHALL remain open to revision when relevant new information, evidence, or changes in the clinical situation become available.
Definition
Revision is the deliberate reconsideration of a previous medical assessment in light of relevant information that was not adequately available, considered, or weighted when the previous assessment was made.
Revision may concern
- a diagnostic hypothesis,
- a diagnosis,
- the interpretation of a finding,
- the relevance of an investigation,
- or the overall understanding of the patient's medical situation.
Revision does not necessarily mean that the previous assessment was wrong.
Principle
A previous diagnostic assessment SHALL NOT be regarded as permanently final when relevant new evidence provides a reasonable basis for reconsideration.
New information SHALL be evaluated in relation to the existing diagnostic assessment.
Where the new information materially changes the evidentiary basis, the diagnostic assessment SHOULD be reconsidered.

Key Message
A diagnosis may be revised when the evidence changes — without rewriting the past.
