ICD-10 Code I69.852 – Hemiplegia and Hemiparesis Following Other Cerebrovascular Disease Affecting Left Dominant Side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.852 – Hemiplegia and hemiparesis following other cerebrovascular disease affecting left dominant side
What it is
This code identifies lasting weakness or paralysis on the left side after a prior cerebrovascular disease other than stroke. Use it when the left side is the dominant side and the deficit is a sequela, not an acute event.
Clinical signs
Typical findings include reduced strength, poor coordination, or limited movement on the left side. Clinical features vary; refer to documentation for whether the deficit is hemiplegia or hemiparesis and whether dominance is documented.
When to use this code
Use I69.852 when the record links current left-sided weakness to a previous cerebrovascular condition and the provider documents it as a residual effect. You should code it for chronic deficits seen during follow-up, rehabilitation, or ongoing neurologic care. Confirm the side, dominance, and that the condition is a sequela.
Do not use for
Do not use this code for an acute cerebrovascular event, unspecified weakness, or deficits without documentation of a prior cerebrovascular disease. Check documentation if the affected side or dominant side is not clearly stated.
Coding tip
Link the residual weakness to the prior cerebrovascular disease in the provider note before assigning this code.
