Neoplasm of unspecified behavior of retina and choroid

This code signifies a tumor of the retina or choroid where the behavior (benign, malignant, or uncertain) has not been definitively determined by pathology or clinical evaluation. It represents an abnormal growth within the posterior segment of the eye that requires further investigation.

This code is appropriate when a mass or lesion is identified in the retina or choroid, but the physician's documentation does not specify its benign or malignant nature. It is typically used when a biopsy has not yet been performed or the results are pending, or when the clinical picture does not clearly indicate a specific behavior.

• Do not use this code if the documentation clearly states the neoplasm is benign (e.g., choroidal nevus) or malignant (e.g., retinoblastoma).
• Always query the provider for clarification on the tumor's behavior if possible, to allow for more specific coding.
• Sequence this code as the primary diagnosis when the neoplasm is the reason for the encounter, or as a secondary diagnosis if it's an incidental finding being monitored.
