Monoplg low lmb fol oth cerebvasc dis aff left nondom side

This code signifies paralysis affecting a single lower limb (monoplegia) that occurs as a residual effect of a cerebrovascular disease other than a stroke, such as a transient ischemic attack (TIA) or cerebral aneurysm rupture. Specifically, the neurological deficit is localized to the left lower extremity and is attributed to an event impacting the non-dominant side of the brain.

Apply this code when documentation clearly indicates a patient presents with left lower limb monoplegia as a sequela of a cerebrovascular event other than a stroke. The medical record must specify the laterality (left) and the non-dominant side of the brain as the affected area. This code is appropriate for chronic or long-term neurological deficits.

• Ensure the documentation explicitly states "monoplegia" of the lower limb and specifies "left" laterality.
• Verify the cerebrovascular disease is not a stroke (e.g., TIA, cerebral hemorrhage without infarction, subarachnoid hemorrhage) and that the affected side is non-dominant.
• This code is for sequelae; an additional code for the underlying cerebrovascular disease (e.g., I69.8-) should be sequenced first if it is still active or relevant to the current encounter.
