Monoplg upr lmb fol oth cerebvasc disease aff unsp side

This diagnosis code signifies paralysis affecting a single upper limb (arm or hand) that occurs as a sequela of a cerebrovascular event other than a stroke, such as a transient ischemic attack (TIA) or cerebral aneurysm rupture. The specific side of the body affected by the monoplegia is not documented or is unknown.

Use this code when documentation clearly indicates monoplegia of an upper extremity as a residual effect of a cerebrovascular disease other than a stroke, and the laterality is not specified. This code is appropriate for chronic or long-term neurological deficits.

• Always sequence this code after the code for the underlying cerebrovascular disease, if still active.
• Ensure documentation specifies "monoplegia" and not hemiplegia or paresis, and that it affects an "upper limb."
• Avoid using this code if the cerebrovascular event is explicitly documented as a stroke; instead, refer to codes within the I69.3 or I69.9 categories.
