Malignant neoplasm of unspecified ciliary body

This code signifies a cancerous growth originating in the ciliary body of the eye, where the specific side (right or left) is not documented. The ciliary body is a part of the uvea, responsible for aqueous humor production and accommodation. This malignancy can affect vision and ocular health.

Apply this code when documentation confirms a primary malignant neoplasm of the ciliary body, but the laterality (right or left eye) is not specified by the provider. This is typically used when the pathology report or physician's notes identify the tumor's location as the ciliary body without further detail on the affected eye.

• Always query the provider for laterality if not documented to allow for a more specific code (C69.41 or C69.42).
• Do not use this code if the documentation specifies a benign neoplasm or a neoplasm of uncertain behavior; refer to the D codes for those scenarios.
• Sequence this code as the primary diagnosis when the malignant neoplasm of the ciliary body is the reason for the encounter.
