ICD-10 Code H05.41 – Enophthalmos due to atrophy of orbital tissue (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.41 – Enophthalmos due to atrophy of orbital tissue
What it is
H05.41 identifies sunken appearance of the eye caused by loss or wasting of orbital tissue. Use it when the record specifically links enophthalmos to orbital atrophy.
Clinical signs
Typical findings include posterior displacement of the globe, facial asymmetry, and a visibly deepened upper eyelid sulcus. Clinical features vary; refer to documentation.
When to use this code
Use H05.41 when the clinician documents enophthalmos attributed to atrophy of orbital tissue, such as after chronic tissue loss or degenerative change. You should code it when the etiology is stated clearly in the assessment or imaging report. If the note only says “sunken eye” without cause, check documentation.
Do not use for
Do not use this code for enophthalmos from trauma, fracture, surgery, or other specified orbital disorders unless orbital atrophy is documented. Do not assign it for nonspecific eye asymmetry.
Coding tip
Verify that the cause is orbital tissue atrophy, not just enophthalmos, before assigning H05.41.
