I69.961

HCC Category Mapping

What This Code Means

This code describes weakness or loss of muscle function on the right side of the body that resulted from a previous stroke or brain blood vessel problem, where the specific type of cerebrovascular event is not documented. The right side is the person's dominant side (usually their stronger, more coordinated side).

Coding Tips

• •Use this code only when the cerebrovascular disease type is truly unspecified; if the stroke type (ischemic, hemorrhagic, etc.) is documented, use a more specific code from the I69 category
• •Ensure documentation supports that this is a late effect/sequela of a prior cerebrovascular event, not an acute stroke; the I69 category is specifically for post-stroke conditions

Clinical Significance

Other paralytic syndromes following unspecified cerebrovascular disease capture residual motor deficits that do not fit the classic patterns of hemiplegia or monoplegia, such as locked-in syndrome, quadriplegia, or atypical paralytic presentations following cerebrovascular events. These conditions often require complex, multidisciplinary care including neurological monitoring, physical and occupational therapy, and specialized nursing services. Proper coding ensures these high-acuity, high-resource patients are appropriately reflected in risk adjustment calculations.

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
• ✓Description of the specific paralytic pattern (e.g., quadriplegia, locked-in syndrome, or other specified pattern) that distinguishes this from hemiplegia or monoplegia
• ✓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)
