Rhinosporidiosis

This code represents rhinosporidiosis, a chronic granulomatous fungal infection primarily affecting the mucous membranes of the nose and nasopharynx. It is characterized by the development of friable, polypoidal lesions that can bleed easily. The causative agent is Rhinosporidium seeberi.

Use this code when documentation confirms a diagnosis of rhinosporidiosis, typically identified through biopsy of the characteristic lesions. This code is appropriate for cases involving the nasal cavity, nasopharynx, or other mucous membrane sites affected by this specific fungal infection.

• Ensure the pathology report explicitly identifies Rhinosporidium seeberi or rhinosporidiosis.
• Do not confuse with other fungal infections or benign nasal polyps; specific identification is crucial.
• Consider additional codes for anatomical sites of involvement if documented (e.g., for conjunctival lesions).
