Monoplg upr lmb fol ntrm subarach hemor aff left dom side

This code signifies paralysis affecting a single upper limb (monoplegia) that developed as a sequela of a subarachnoid hemorrhage not caused by trauma. Specifically, it indicates that the left upper extremity is affected in a patient whose left side is dominant.

Apply this code when documentation clearly states left upper limb monoplegia resulting from a previous nontraumatic subarachnoid hemorrhage in a left-handed individual. This code is used for the long-term neurological deficit, not the acute hemorrhage itself. Supporting documentation should specify the laterality of the monoplegia and the patient's handedness.

• Ensure the documentation specifies "nontraumatic" subarachnoid hemorrhage as the etiology of the monoplegia.
• Confirm the affected limb is the left upper and that the patient is left dominant.
• Do not use this code for acute subarachnoid hemorrhage; it is for the residual neurological deficit.
