ICD-10 Code H05.401 – Unspecified enophthalmos, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.401 – Unspecified enophthalmos, right eye
What it is
This code identifies a backward displacement of the right eyeball into the orbit when the cause is not specified. Use it when documentation confirms enophthalmos but does not state the underlying condition.
Clinical signs
Typical findings include a sunken appearance of the right eye and a deeper-looking upper eyelid sulcus. Clinical features vary; refer to documentation for the recorded exam findings.
When to use this code
Use H05.401 when the provider documents unspecified enophthalmos limited to the right eye. It is appropriate when the note does not identify trauma, orbital disease, or another cause. Code the documented laterality exactly as written.
Do not use for
Do not use this code if the record identifies a specific cause of enophthalmos or a different eye. Check documentation when the finding is bilateral, left-sided, or described with another orbital disorder.
Coding tip
Verify laterality and whether the provider documented a cause before assigning the unspecified code.
