ICD-10 Code I69.862 – Other paralytic syndrome following other cerebrovascular disease affecting left dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.862 – Other paralytic syndrome following other cerebrovascular disease affecting left dominant side
What it is
This code identifies residual paralysis or weakness on the left dominant side after a prior cerebrovascular disease other than stroke. Use it for lasting neurologic deficits that remain after the acute event has passed.
Clinical signs
Typical findings include persistent left-sided motor weakness, impaired coordination, or decreased voluntary movement. Clinical features vary; refer to documentation for the exact residual deficit and whether dominance is specified.
When to use this code
Use I69.862 when the record states a paralytic syndrome is a late effect of another cerebrovascular disease and the affected side is left dominant. It is appropriate for follow-up encounters documenting ongoing deficits after the original cerebrovascular event.
Do not use it for an acute neurologic episode or when the deficit is not clearly linked to a prior cerebrovascular condition. Check documentation if the side, dominance, or cause is unclear.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or weakness from non-cerebrovascular causes. It is also incorrect if the residual paralysis is not documented as affecting the left dominant side.
Coding tip
Verify that the chart links the paralysis to a previous cerebrovascular disease and documents laterality and dominance before assigning this code.
