ICD-10 Code I69.844 – Monoplegia of lower limb following other cerebrovascular disease affecting left non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.844 – Monoplegia of lower limb following other cerebrovascular disease affecting left non-dominant side
What it is
This code identifies one-sided paralysis or severe weakness of the lower limb that remains after a nontraumatic cerebrovascular disease. It specifies the left, non-dominant side, so you should confirm laterality and dominance in the record.
Clinical signs
Typical findings include marked weakness or loss of voluntary movement in one leg, often with gait impairment or need for assistance. Clinical features vary; refer to documentation for the documented post-stroke deficit and affected side.
When to use this code
Use I69.844 when the chart documents residual monoplegia of the left lower limb due to a prior cerebrovascular disease, and the provider identifies the non-dominant side. This is a sequela code, so it describes the lasting neurologic deficit rather than the acute event. Check documentation if the record does not clearly link the deficit to the cerebrovascular condition.
Do not use for
Do not use this code for acute stroke, transient weakness, or hemiplegia affecting both arm and leg. If the side, dominance, or cause is unclear, check documentation.
Coding tip
Verify that the residual deficit is documented as due to a prior cerebrovascular disease and that left non-dominant side is explicitly stated.
