ICD-10 Code I69.143 – Monoplegia of lower limb following nontraumatic intracerebral hemorrhage affecting right non-dominant side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.143 – Monoplegia of lower limb following nontraumatic intracerebral hemorrhage affecting right non-dominant side
What it is
This code identifies monoplegia, or paralysis affecting one lower limb, as a late effect of a nontraumatic intracerebral hemorrhage. It also specifies the right side and that the affected side is non-dominant.
Clinical signs
Typical findings include marked weakness or paralysis in one leg, reduced voluntary movement, and impaired walking or balance after a prior brain bleed. Clinical features vary; refer to documentation.
When to use this code
Use I69.143 when the record links the lower-limb monoplegia to a previous nontraumatic intracerebral hemorrhage and documents the right non-dominant side. The condition should be described as a sequela, not an acute event. Check documentation if dominance or laterality is unclear.
Do not use for
Do not use this code for acute intracerebral hemorrhage, generalized hemiplegia, or lower-limb weakness without a documented stroke sequela. Do not assign it if the chart does not confirm the causal relationship.
Coding tip
Verify both the residual deficit and the side affected, because I69 codes require precise documentation of the prior hemorrhage and the current sequela.
