ICD-10 Code H05.403 – Unspecified enophthalmos, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.403 – Unspecified enophthalmos, bilateral
What it is
H05.403 identifies inward sinking or posterior displacement of both eyes, with no further cause or type specified. Use it when the record documents bilateral enophthalmos but does not name an underlying condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include a sunken appearance of both eyes, reduced orbital prominence, or asymmetry noted on exam or imaging.
When to use this code
Use this code when the provider documents bilateral enophthalmos and does not specify traumatic, congenital, postoperative, or disease-related cause. It also fits cases where the chart confirms the finding but the etiology remains unclear.
If the record names a specific underlying disorder, code that condition instead or in addition, as supported by the documentation. Check documentation for laterality and whether the enophthalmos is truly bilateral.
Do not use for
Do not use this code for unilateral enophthalmos or for eye displacement caused by a documented specific condition when a more precise code is available. Do not use for proptosis or other orbital abnormalities.
Coding tip
Verify that “bilateral” is explicitly documented before assigning H05.403, and look for a stated cause that may require separate coding.
