ICD-10-CM Code H49.01
Third [oculomotor] nerve palsy, right eye
Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.H49.01 is a billable ICD code used to specify a diagnosis of third [oculomotor] nerve palsy, right eye. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H490 is used to code Oculomotor nerve palsy
Oculomotor nerve palsy or third nerve palsy is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements. Thus, damage to this nerve will result in the affected individual being unable to move his or her eye normally. In addition, the nerve also supplies the upper eyelid muscle (Levator palpebrae superioris) and the muscles responsible for pupil constriction (sphincter pupillae) . The limitations of eye movements resulting from the condition are generally so severe that the affected individual is unable to maintain normal alignment of their eyes when looking straight ahead, leading to strabismus and, as a consequence, double vision (diplopia).
