Mild neurocog disord d/t known physiol cond w/o beh distrb

This code signifies a mild decline in cognitive function, such as memory, attention, or executive function, that is attributable to an underlying medical condition or substance use. The cognitive deficits are noticeable to the individual or others but do not significantly interfere with daily activities. Importantly, there are no associated behavioral disturbances like agitation, psychosis, or mood swings.

Use this code when documentation clearly indicates a mild neurocognitive disorder with an identified physiological cause (e.g., traumatic brain injury, Parkinson's disease, HIV infection) and explicitly states the absence of behavioral or psychological symptoms. This diagnosis requires evidence of cognitive decline from a previous level of functioning, confirmed by clinical assessment or standardized testing. It is appropriate when the cognitive impairment is not severe enough to meet criteria for major neurocognitive disorder.

• Ensure the documentation specifies "mild" neurocognitive disorder and identifies the underlying physiological condition.
• Do not use this code if behavioral disturbances (e.g., aggression, hallucinations) are present; instead, consider codes with behavioral disturbance specifications.
• Sequence the underlying physiological condition as the primary diagnosis if it is the reason for the encounter, with this code as a secondary diagnosis.
