378.0 Strabismus and other disorders of binocular eye movements (378) ICD-9 code 378 for Strabismus and other disorders of binocular eye movements is a medical classification as listed by WHO under the range -DISORDERS OF THE EYE AND ADNEXA (360-379).
Learn to Code Pediatrics and Strabismus is available at the Academy store.
The movements of each eye are controlled by 6 muscles—some horizontal, some vertical. The CPT codes for surgery depend on which muscles are involved (see “Strabismus Codes,” below).
The 6 add-on codes listed below can’t be reported as stand-alone codes; instead, use them in addition to any of the primary procedure muscle codes. Add-on codes are exempt from multiple-procedure payment rules, so payment is 100% of the allowable.
Example. A patient who had had previous bilateral strabismus surgery returned for bilateral lateral rectus resections. In addition, the surgeon explored the inferior obliques. Here’s how to code for the visit.
