Monoplg low lmb following ntrm subarach hemor aff unsp side

This code signifies paralysis affecting a single lower limb that occurs as a sequela of a nontraumatic subarachnoid hemorrhage. The paralysis is not due to an injury and the specific side of the body affected is not documented. This represents a long-term neurological deficit resulting from a previous cerebrovascular event.

This code is used when a patient presents with monoplegia of an unspecified lower limb, and the medical record clearly links this paralysis to a prior nontraumatic subarachnoid hemorrhage. Documentation should specify the paralysis as a residual effect and confirm the nontraumatic origin of the hemorrhage.

• Ensure the documentation explicitly states "unspecified side" for the monoplegia; otherwise, a more specific code (e.g., I69.041, I69.042) should be used.
• This code is a sequela code, meaning it should be used for conditions that are residual effects of a previous cerebrovascular accident.
• Do not confuse with acute monoplegia or monoplegia due to traumatic injury; those conditions have different coding pathways.
