I69.049 Monoplegia of lower limb following nontraumatic subarachnoid hemorrhage affecting unspecified side

Billable ICD-10-CM code, FY2026. Exempt from present-on-admission (POA) reporting.

Applies from I69 Sequelae of cerebrovascular disease

Excludes1 (never code together)

• personal history of cerebral infarction without residual deficit (Z86.73)
• personal history of prolonged reversible ischemic neurologic deficit (PRIND) (Z86.73)
• personal history of reversible ischemic neurologcial deficit (RIND) (Z86.73)
