What This Code Means

Weakness or paralysis affecting one entire side of the body following a stroke or other blood vessel disease, but the specific side of the body or dominance is not documented or specified.

Coding Tips

•Use only when laterality and dominance information cannot be determined from available documentation
•Attempt to query provider for complete laterality and dominance information when possible

Clinical Significance

Hemiplegia and hemiparesis following other cerebrovascular disease represents one of the most functionally devastating sequelae of stroke, affecting an entire side of the body and profoundly limiting mobility, self-care, and independence. This condition carries higher resource utilization than monoplegia due to the greater scope of neurological impairment and the need for intensive rehabilitation, durable medical equipment, and caregiver support. Accurate coding is critical for risk adjustment as hemiplegia maps to a higher-weighted HCC than monoplegia, reflecting its greater clinical severity.

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
✓Documentation specifying whether the deficit is complete paralysis (hemiplegia) or partial weakness (hemiparesis)
✓Affected side should be documented when clinically known; query the provider if laterality is not specified to allow more specific code assignment
✓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)
