About I69.34

I69.34 is the ICD-10-CM diagnosis code for monoplegia of lower limb following cerebral infarction. It belongs to category I69 (sequelae of cerebrovascular disease), block I60-I69 (cerebrovascular diseases) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within I69.3 (sequelae of cerebral infarction), I69.34 is specifically for monoplegia of lower limb following cerebral infarction. Related codes cover unspecified sequelae of cerebral infarction (I69.30), cognitive deficits following cerebral infarction (I69.31), speech and language deficits following cerebral infarction (I69.32), monoplegia of upper limb following cerebral infarction (I69.33), hemiplegia and hemiparesis following cerebral infarction (I69.35), other paralytic syndrome following cerebral infarction (I69.36) and other sequelae of cerebral infarction (I69.39).

To report this condition, pick the subcode that matches the documentation: I69.341 (affecting right dominant side), I69.342 (affecting left dominant side), I69.343 (affecting right non-dominant side), I69.344 (affecting left non-dominant side) and I69.349 (affecting unspecified side).
