ICD-10 Code I69.249 – Monoplegia of lower limb following other nontraumatic intracranial hemorrhage affecting unspecified side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I69.249 – Monoplegia of lower limb following other nontraumatic intracranial hemorrhage affecting unspecified side
What it is
This code describes persistent one-leg paralysis or severe weakness that remains after a nontraumatic intracranial hemorrhage. The affected side is not specified in the documentation.
Clinical signs
Findings typically include loss of voluntary movement, marked weakness, or abnormal tone in one lower limb after a prior brain bleed. Clinical features vary; refer to documentation.
When to use this code
Use I69.249 when the record clearly links current monoplegia of a lower limb to a past nontraumatic intracranial hemorrhage. The hemorrhage is not acute, and the side of the affected leg is not documented.
This is appropriate for aftercare, follow-up, or chronic neurologic deficits documented as residual effects. Check documentation if the record instead describes generalized weakness, paraplegia, or an active stroke event.
Do not use for
Do not use this code for acute intracranial hemorrhage or for weakness without a documented causal link to a prior hemorrhage. It also does not fit when the affected side is specified differently.
Coding tip
Look for wording such as “late effect,” “residual,” or “due to prior hemorrhage” before assigning this code.
