Atrophy of right orbit

This code signifies a reduction in the size and volume of the bony cavity that houses the right eyeball and its associated structures. This atrophy can result from various underlying conditions, leading to a sunken appearance of the eye (enophthalmos) and potential functional impairments.

Use this code when documentation explicitly states atrophy of the right orbit. This typically occurs following trauma, surgical removal of orbital contents, chronic inflammation, or certain systemic diseases affecting bone or soft tissue. Supporting documentation should include imaging reports (e.g., CT, MRI) confirming orbital volume loss.

• Ensure laterality is clearly documented (right vs. left vs. bilateral).
• Investigate and code any underlying cause of the orbital atrophy, if known, as a primary or secondary diagnosis.
• Distinguish from enophthalmos (H07.1-), which describes the posterior displacement of the eyeball, though often a consequence of orbital atrophy.
