Benign neoplasm of left ciliary body

This code signifies the presence of a non-cancerous growth originating in the ciliary body of the patient's left eye. The ciliary body is a part of the uvea, located behind the iris, and plays a crucial role in aqueous humor production and accommodation. A benign neoplasm indicates the growth is not malignant and typically does not spread to other parts of the body.

Use this code when documentation clearly states a benign tumor or mass is identified in the ciliary body of the left eye. This diagnosis is often made following ophthalmic examination, imaging studies (e.g., ultrasound biomicroscopy, MRI), or biopsy confirming benign histology. Supporting documentation should specify the laterality.

• Ensure the documentation explicitly states "benign" and specifies the "left" eye.
• Do not confuse with malignant neoplasms of the ciliary body (C69.42) or unspecified neoplasms (D48.7).
• Always review pathology reports if a biopsy was performed to confirm the benign nature of the lesion.
