BillableMonoplegia of lower limb following other cerebrovascular disease affecting right non-dominant side
HCC Category Mapping
What This Code Means
This code describes weakness or paralysis affecting one leg on the right side of the body as a result of a stroke or other brain blood vessel disease. The right side is the non-dominant side (not the person's main/preferred side for activities).
Coding Tips
- •Verify the cerebrovascular event has been documented and sequenced as the underlying cause before assigning this code, as it represents a late effect (sequela)
- •Confirm laterality documentation specifies 'right non-dominant side' and that the monoplegia affects the lower limb only; if upper limb is also affected, use hemiplegia codes instead
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)
