Fntl lb and exec fcn def following unsp cerebvasc disease

This code signifies a cognitive impairment characterized by deficits in frontal lobe functions and executive abilities, such as planning, problem-solving, decision-making, and impulse control. These neurological sequelae are directly attributable to a cerebrovascular event of an unspecified nature.

Apply this code when documentation clearly indicates post-stroke cognitive impairment specifically affecting frontal lobe and executive functions, and the type of cerebrovascular disease is not specified. This is appropriate for chronic, residual deficits rather than acute stroke symptoms. Documentation should specify the link between the cerebrovascular event and the cognitive deficits.

• Ensure the documentation explicitly links the frontal lobe/executive function deficit to a previous cerebrovascular disease, not an active stroke.
• Avoid using this code if the specific type of cerebrovascular disease (e.g., ischemic, hemorrhagic) is documented; instead, use a more specific I69.x14 code.
• This code should be sequenced after the code for the underlying cerebrovascular disease (if still active and relevant) or as a primary diagnosis if the sequela is the primary reason for the encounter.
