M1700 & M1710. What is the difference in what is measured in M1700 - Cognitive Functioning and M1710 - When Confused?
M1700 - Cognitive Functioning, is intended to report the patient's cognitive functioning, as evidenced by their level of alertness, orientation, comprehension, concentration, and immediate memory for simple commands on the day of assessment (at the time of the assessment and in the preceding 24 hours). M1710 - When Confused, is intended to identify the time of day or situations when the patient experienced confusion, if at all, during the past 14 days (Day of assessment and prior 14 days). M1710 - Confusion, may not directly relate to M1700 - Cognitive Functioning. Confusion is defined in Mosby's Medical Dictionary as "a mental state characterized by disorientation regarding time, place, person, or situation. It causes bewilderment, perplexity, lack of orderly thought, and inability to choose or act decisively and perform the activities of daily living. It is usually symptomatic of an organic mental disorder, but it may accompany severe emotional stress and various psychological disorders." If a patient is demonstrating confusion on the day of the assessment, it would be reported both in M1700 and M1710. If a patient was NOT confused on the day of assessment, but had experienced confusion during the prior 14 days, it would only be reported in M1710. If a patient has a cognitive impairment on the day of the assessment, that does NOT result in confusion, e.g., forgetfulness, learning disabilities, concentration difficulties, decreased intelligence, it would only be reported in M1700.
