What This Code Means

Weakness or paralysis affecting one entire side of the body (arm and leg together) on the right side after a stroke, in a person whose dominant side is the right.

Coding Tips

• •Hemiplegia involves both upper and lower limbs on the same side; do not confuse with monoplegia
• •Right dominant is the most common presentation; document dominance clearly

Clinical Significance

Hemiplegia and hemiparesis as a sequela of a cerebral infarction (ischemic stroke) represents a chronic neurological deficit that significantly impacts the patient's functional status and ongoing care needs. Hemiplegia involves paralysis or significant weakness affecting one entire side of the body, requiring ongoing rehabilitation, fall prevention strategies, and often assistive devices for activities of daily living. This condition is a key risk adjustment indicator as it reflects severe neurological damage with high resource utilization for therapy, home health, and durable medical equipment.

Documentation Requirements

• ✓Documentation of prior cerebral infarction (stroke) 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
• ✓Description of hemiplegia or hemiparesis affecting one entire side of the body (both upper and lower extremities)
• ✓Current functional status and severity of the hemiplegia/hemiparesis (complete vs incomplete paralysis)
• ✓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
