Monocular exotropia, right eye
ICD10CM code
Name of the Condition
- Monocular Exotropia, Right Eye
- Commonly referred to as "outward turning of the right eye" or simply "right eye exotropia."
Summary
Monocular exotropia of the right eye is a condition where the right eye deviates outward while the other eye focuses normally. It is a type of strabismus, which can affect vision and depth perception.
Causes
- Genetic predisposition to strabismus.
- Neuromuscular control issues affecting eye muscles.
- Impact or damage to cranial nerves.
- Eye injuries or underlying medical conditions affecting muscle coordination.
Risk Factors
- Family history of strabismus or refractive errors.
- Conditions such as cerebral palsy or Down syndrome.
- Premature birth or low birth weight.
- Uncorrected refractive errors.
Symptoms
- Noticeable outward deviation of the right eye.
- Double vision or diplopia.
- Difficulty with depth perception.
- Eye strain or discomfort.
- The head may turn to better align vision.
Diagnosis
- Comprehensive eye examination by an ophthalmologist or optometrist.
- Cover test or Hirschberg test to assess eye alignment.
- Additional imaging if necessary to rule out neurological causes.
Treatment Options
- Corrective eyeglasses or contact lenses: Can ease strain and help in minor cases.
- Vision therapy: Exercises to improve coordination and muscular control of the eyes.
- Prism lenses: Helps correct the alignment of light entering the eye.
- Surgical intervention: To realign eye muscles if other treatments are ineffective.
Prognosis and Follow-Up
With proper treatment, symptoms can often be managed effectively. Regular monitoring is essential to ensure the treatment remains effective and to adjust therapies as needed.
Complications
- Amblyopia (lazy eye) if left untreated in children.
- Significant impact on depth perception and binocular vision.
- Psychological or social implications due to cosmetic concerns.
Lifestyle & Prevention
- Early detection and treatment of any vision issues.
- Regular eye check-ups, especially for those with a family history of eye conditions.
- Protective eyewear to prevent injuries.
When to Seek Professional Help
- Sudden onset of double vision or exotropic symptoms.
- Persistent or worsening misalignment of the eye.
- Noticeable changes in depth perception or visual clarity.

Tips for Medical Coders
- Ensure the correct laterality when coding: H50.111 specifies the right eye.
- Double-check documentation to confirm monocular versus binocular presentation.
- Be aware of associated conditions or treatments documented, which may require additional codes.
