What This Code Means

Weakness or paralysis of one leg on the left side of the body that resulted from bleeding in the brain, where the left side is the person's dominant side.

Coding Tips

• •Verify documentation specifies 'other nontraumatic intracranial hemorrhage' as the cause, not traumatic injury
• •Confirm laterality and dominance are clearly documented to select the correct fifth character

Clinical Significance

Monoplegia of the lower limb as a sequela of a nontraumatic intracranial hemorrhage other than intracerebral (such as subarachnoid or subdural hemorrhage) represents a chronic neurological deficit that significantly impacts the patient's functional status and ongoing care needs. Lower limb monoplegia significantly impacts mobility, increases fall risk, and typically requires physical therapy, assistive devices, and ongoing monitoring. This diagnosis is important for risk adjustment as it indicates persistent functional impairment requiring sustained rehabilitative and medical resources.

Documentation Requirements

• ✓Documentation of prior other nontraumatic intracranial hemorrhage as the causative event with clear causal linkage to the current deficit
• ✓Confirmation that this is a sequela (late effect), not an acute or current cerebrovascular event
• ✓Documentation that paralysis or weakness is isolated to one lower extremity (leg)
• ✓Current functional status of the affected lower limb including strength and mobility assessment
• ✓Documentation of which side is affected (right or left)
• ✓Documentation of patient's hand dominance to determine dominant vs non-dominant classification
• ✓Current treatment plan including rehabilitation services, medications, and adaptive equipment
• ✓Assessment that the condition is being actively monitored or managed during the encounter
