Constant exophthalmos, left eye

This code signifies a persistent protrusion of the eyeball from the orbit, specifically affecting the left eye. This condition is non-intermittent and indicates a sustained forward displacement of the globe.

Apply this code when documentation clearly states "constant exophthalmos" or "proptosis" of the left eye. This is often associated with conditions like Graves' ophthalmopathy, orbital tumors, or inflammatory orbital pseudotumor.

• Differentiate from intermittent exophthalmos, which would require a different code.
• Ensure laterality is explicitly documented as "left eye" to support this specific code.
• Code any underlying cause of the exophthalmos, such as endocrine disorders, in addition to this code.
