ICD-10 Code H05.402 – Unspecified enophthalmos, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.402 – Unspecified enophthalmos, left eye
What it is
H05.402 identifies inward displacement of the left eyeball without a stated cause. Use it when the record says enophthalmos in the left eye but does not specify the underlying condition.
Clinical signs
Typical findings include a sunken-appearing left eye, reduced orbital prominence, or facial asymmetry. Clinical features vary; refer to documentation for the exact exam findings and any associated orbital disorder.
When to use this code
Use this code when the provider documents unspecified enophthalmos of the left eye and no more specific diagnosis is available. It may appear in ophthalmology, trauma, or imaging follow-up notes. If the cause is known, code the documented condition instead.
Do not use for
Do not use it for enophthalmos of the right eye, bilateral enophthalmos, or a documented underlying orbital disease with a more specific code. Check documentation.
Coding tip
Verify laterality and whether the chart states a cause, because unspecified enophthalmos should be coded only when no more specific diagnosis is documented.
