H49.22 is a billable ICD code used to specify a diagnosis of sixth [abducent] nerve palsy, left eye. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code H492 is used to code Sixth nerve palsy

Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. The inability of an eye to turn outward results in a convergent strabismus or esotropia of which the primary symptom is double vision or diplopia in which the two images appear side-by-side. The condition is commonly unilateral but can also occur bilaterally.
