Monoplg upr lmb following ntrm subarach hemor aff unsp side

This code signifies the presence of monoplegia, specifically affecting an upper limb, as a sequela of a nontraumatic subarachnoid hemorrhage. It indicates a paralysis or severe weakness impacting a single arm, resulting from a prior bleed around the brain that was not caused by trauma. The laterality of the affected upper limb is not specified.

Use this code when documentation clearly states monoplegia of an upper extremity as a residual effect of a nontraumatic subarachnoid hemorrhage. This applies to chronic or long-term neurological deficits directly attributable to the prior hemorrhage. The physician's assessment should confirm the causal link and the specific limb affected.

• Ensure the documentation specifies "nontraumatic" subarachnoid hemorrhage as the etiology of the monoplegia.
• Do not use if the monoplegia is due to a traumatic subarachnoid hemorrhage; refer to codes in the T90-T98 range for sequelae of trauma.
• This code is for unspecified side; if laterality (left or right) is documented, use the more specific code (I69.031 or I69.032).
