Enophthalmos due to atrophy of orbital tissue, unsp eye

This code signifies a condition where the eyeball is sunken into the orbit due to a reduction in the volume of the orbital tissues, specifically from atrophy. This atrophy leads to a posterior displacement of the globe, affecting an unspecified eye.

Apply this code when documentation clearly indicates enophthalmos resulting from the wasting away or degeneration of orbital fat or other soft tissues within the eye socket. This typically occurs in cases of trauma, chronic inflammation, or systemic conditions causing tissue loss, where the specific eye affected is not documented.

• Ensure documentation specifies "atrophy of orbital tissue" as the cause of enophthalmos, not other etiologies like fracture or surgical removal.
• If the affected eye (right or left) is specified, use the more precise codes H05.411 or H05.412.
• Code any underlying systemic condition or trauma causing the orbital tissue atrophy as a primary diagnosis, if applicable.
