Prior-encounter information may provide valuable clinical context, but it should not automatically be imported as a current reportable diagnosis without considering whether the condition remains active and relevant to the present encounter.

Here, a prior diagnosis of chronic systolic heart failure, ongoing heart-failure therapy, and ambiguous current wording such as “history of CHF” create a reasonable opportunity to clarify the patient's current heart-failure status if that information is clinically relevant.

The CDI specialist should not independently carry forward the previous diagnosis or escalate it to acute heart failure. Conversely, rigidly ignoring reliable prior clinical information can prevent identification of legitimate documentation gaps.

The 2026 ACDIS/AHIMA query guidance specifically includes the role of prior encounters as part of its updated query-practice framework, while emphasizing compliant provider clarification and accurate representation of the current patient's clinical status.

A query should make clear which current clinical indicators support the need for clarification and should not imply that a previous diagnosis must automatically remain valid.
