Mild neurocog disord d/t known physiol cond with beh distrb

This code signifies a mild decline in cognitive function, such as memory, attention, or executive function, that is attributable to a diagnosed medical condition (e.g., Parkinson's disease, traumatic brain injury, HIV). The patient also exhibits behavioral or psychological symptoms, which may include agitation, aggression, or psychosis, that are directly related to the neurocognitive impairment. This impairment is not severe enough to significantly interfere with independence in daily activities.

Apply this code when documentation clearly links a mild neurocognitive decline and associated behavioral disturbances to an underlying physiological condition. Supporting documentation should include a clinical assessment confirming mild cognitive impairment, a diagnosis of the causative medical condition, and a description of the specific behavioral symptoms present. This code is appropriate when the cognitive deficits are noticeable but do not preclude independent living.

• Always sequence the underlying physiological condition as the primary diagnosis, followed by this code.
• Distinguish from F06.70 (without behavioral disturbance) and more severe neurocognitive disorders (e.g., F02.81, F03.91).
• Ensure the medical record explicitly states the "mild" severity of the neurocognitive disorder and the presence of "behavioral disturbance."
