Frontal lobe and exec fcn def following cerebral infarction

This code signifies a persistent impairment in cognitive functions primarily associated with the frontal lobe, such as planning, problem-solving, decision-making, and impulse control, that directly results from a previous cerebral infarction (ischemic stroke). It describes a chronic neurological sequela affecting higher-level executive processes.

Apply this code when documentation clearly indicates a patient is experiencing ongoing deficits in executive function and/or frontal lobe-specific cognitive abilities, and the medical record explicitly links these deficits to a prior ischemic stroke. This code is appropriate for long-term follow-up care after the acute phase of the stroke.

• Always sequence this code after the appropriate code for the cerebral infarction (e.g., I63.x).
• Ensure documentation specifies "following cerebral infarction" and details the nature of the executive function deficit.
• Distinguish from other post-stroke cognitive deficits not specifically localized to frontal lobe or executive functions.
