What This Code Means

This code describes weakness or paralysis affecting one leg on the left side of the body as a long-term effect of a stroke or other brain blood vessel disease. The left side is the person's dominant (stronger) side.

Coding Tips

•Verify the documentation specifies monoplegia (single limb paralysis) of the lower limb and confirms it is a sequela (late effect) of a prior cerebrovascular event, not an acute stroke
•Confirm the affected side is documented as left and that left dominance is specified; if dominance is not documented, query the provider before coding

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)
