What This Code Means

Weakness or paralysis of one leg on the left side of the body that resulted from a stroke or other blood vessel disease in the brain, where the left side is not the person's dominant side.

Coding Tips

• •Verify documentation specifies 'other cerebrovascular disease' (not initial stroke) and confirm left non-dominant side laterality
• •This code is used for sequelae (late effects) of cerebrovascular events, not acute stroke phase

Clinical Significance

Monoplegia of the lower limb as a sequela of other cerebrovascular disease represents a persistent neurological deficit requiring ongoing management, rehabilitation, and monitoring for functional decline. This diagnosis captures the long-term disability burden from cerebrovascular events and significantly impacts the patient's independence, fall risk, and need for assistive services. Accurate capture is essential for risk adjustment as it reflects the sustained resource utilization associated with post-stroke paralytic syndromes.

Documentation Requirements

• ✓Documentation of the specific type of prior cerebrovascular event (stroke, hemorrhage, or other cerebrovascular disease) that caused the sequela
• ✓Clear statement establishing a causal relationship between the prior cerebrovascular event and the current neurological deficit
• ✓Documentation that the condition is a late effect or sequela, not an acute or evolving stroke
• ✓Specification that the paralysis is isolated to one lower limb (monoplegia), not affecting an entire side of the body
• ✓Documentation of the affected side (right or left) AND whether it is the patient's dominant or non-dominant side
• ✓Current functional status assessment including impact on activities of daily living, mobility, and need for assistive devices or caregiver support
• ✓Ongoing treatment plan addressing the neurological deficit (physical therapy, occupational therapy, medications, or other interventions)
