Granuloma of bilateral orbits

This code signifies the presence of a granulomatous inflammatory lesion affecting both orbital cavities. A granuloma is a localized collection of immune cells that forms when the immune system attempts to wall off foreign substances or infections it perceives as a threat but cannot eliminate. In the orbit, this can lead to mass effect, proptosis, and visual disturbances.

Use this code when documentation explicitly states a diagnosis of granuloma affecting both the left and right orbits. This diagnosis is typically made following imaging studies (e.g., CT, MRI) and often confirmed by biopsy. It is appropriate for conditions such as orbital pseudotumor (when granulomatous in nature and bilateral) or other specific granulomatous diseases impacting both orbits.

• Ensure the documentation clearly specifies bilateral involvement; otherwise, use a code for unilateral granuloma.
• Distinguish from orbital cellulitis or abscess, which are infectious processes and coded differently.
• Look for underlying systemic conditions that may cause orbital granulomas (e.g., sarcoidosis, GPA) and code them as additional diagnoses.
