What does Unknown Response mean?

• A. Response when information is not available.
• B. Response when information is available.
• C. Not Applicable response for this item.
• D. Dash Response

Answer: (A)

Unknown Response is used when the information needed to answer an item isn’t available at the time of the assessment. It signals a data gap that may require follow-up or a subsequent visit to obtain, rather than making an assumption or leaving the item blank. This helps ensure the record accurately reflects what is known versus what is still unknown.

It’s different from Not Applicable, which means the item doesn’t apply to this patient for a specific reason (the data would not be relevant or necessary). It also isn’t a placeholder like a dash; those aren’t formal response options and don’t communicate missing information in the same way. For example, if you can’t determine whether the patient requires assistive devices because you don’t have access to their medical records or caregiver input, you would use Unknown Response rather than guessing or marking the item as not applicable.
