ICD10 code of Duane Syndrome and ICD9 code

Duane Syndrome is classified under ICD-10 code H50.81 (Duane's retraction syndrome) and was historically identified under ICD-9 code 378.71. These diagnostic codes are essential for medical record keeping, insurance authorization, and ensuring consistent clinical tracking for individuals living with this condition.

What is the clinical classification of Duane Syndrome?

Duane Syndrome is a rare congenital ocular motility disorder characterized by the inability of the eye to move outward (abduction) and, in some cases, inward (adduction). By utilizing the specific ICD-10 code H50.81, clinicians can accurately document the presence of Duane Syndrome in a patient's electronic health record, which is vital for coordinating multidisciplinary care between ophthalmologists and neurologists.

How is Duane Syndrome diagnosed?

Diagnosis of Duane Syndrome is primarily clinical, based on a physical examination of eye movements and the characteristic retraction of the eyeball into the socket when looking toward the nose. Because 226 people with Duane Syndrome have shared their experiences on DiseaseMaps.org, we know that many patients seek diagnostic clarity through comprehensive eye exams. Key diagnostic features often include:

• Limited abduction (outward movement) of the affected eye.


• Retraction of the globe (eyeball) upon adduction.


• Narrowing of the palpebral fissure (eyelid opening) during adduction.


• Possible "up-shoot" or "down-shoot" phenomena during attempted adduction.

Is Duane Syndrome hereditary or genetic?

While most cases of Duane Syndrome occur sporadically, approximately 10% of cases are associated with a family history. Researchers have identified mutations in the CHN1, MAFB, and SALL4 genes as potential contributors to the development of Duane Syndrome. Understanding the genetic basis is an active area of study for those managing the long-term ocular health of patients with the condition.

Next steps

• Schedule a consultation with a pediatric ophthalmologist or a strabismus specialist to monitor binocular vision.


• Connect with the community of 226 members on DiseaseMaps.org to share lived experiences and coping strategies.


• Request that your healthcare provider uses the correct ICD-10 code (H50.81) to ensure accurate medical history documentation.
