Tenonitis of left orbit

This code signifies inflammation of Tenon's capsule, a fibrous membrane that envelops the eyeball from the limbus to the optic nerve, specifically affecting the left eye. This condition can lead to pain, proptosis (bulging of the eye), and restricted ocular motility.

Apply this code when documentation clearly indicates inflammation or infection of Tenon's capsule affecting the left orbit. Supporting documentation should include physician notes detailing symptoms like left eye pain, swelling, or limited movement, along with diagnostic findings confirming tenonitis.

• Ensure laterality is explicitly documented as "left" to support this specific code.
• Differentiate from orbital cellulitis (H05.01-) or other orbital inflammatory disorders.
• Look for associated underlying causes, such as infection or autoimmune conditions, which may require additional codes.
