Response options

ValueMeaning
0Alert/oriented, able to focus and shift attention, comprehends and recalls task directions independently.
1Requires prompting (cueing, repetition, reminders) only under stressful or unfamiliar conditions.
2Requires assistance and some direction in specific situations (for example, on all tasks involving shifting of attention) or consistently requires low stimulus environment due to distractibility.
3Requires considerable assistance in routine situations. Is not alert and oriented or is unable to shift attention and recall directions more than half the time.
4Totally dependent due to disturbances such as constant disorientation, coma, persistent vegetative state, or delirium.

How to score it

Assess the patient's current level (day of assessment, considering the preceding 24 hours) of alertness, orientation, comprehension, concentration, and immediate memory for simple commands — interview the patient and/or caregiver and review referral information. Consider both the signs/symptoms of cognitive dysfunction observed and the amount of supervision/care those deficits require. Dash is not a valid response for this item.

The common error

Coding from a documented diagnosis (for example dementia) alone rather than the patient's actual current functional presentation — CMS's coding tip notes several diagnoses (dementia, delirium, developmental delay, stroke-related deficits, opioid therapy) can produce cognitive dysfunction, but the code must reflect the patient's observed alertness/orientation/comprehension that day, not the diagnosis itself.
