Cellulitis of bilateral orbits

This code represents an acute bacterial infection of the soft tissues surrounding both eyeballs, extending into the orbital septum. It is characterized by inflammation, swelling, pain, and erythema affecting both orbits. This condition can be sight-threatening and potentially life-threatening if left untreated due to its proximity to the brain.

Use this code when documentation clearly indicates cellulitis affecting both the left and right orbits. This diagnosis is typically supported by physical exam findings of bilateral periorbital edema, erythema, tenderness, and possibly proptosis, along with imaging studies (e.g., CT scan) confirming orbital involvement.

• Differentiate from preseptal (periorbital) cellulitis, which does not involve the orbital contents.
• Ensure documentation specifies "bilateral" involvement; otherwise, a unilateral code may be more appropriate.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any underlying cause or associated conditions.
