Rhinosporidiosis

This code represents rhinosporidiosis, a chronic granulomatous fungal infection caused by Rhinosporidium seeberi. It primarily affects mucous membranes, most commonly the nose and nasopharynx, but can also involve the conjunctiva, larynx, genitalia, and skin. Lesions typically present as friable, polypoid masses that bleed easily.

Use this code when documentation confirms a diagnosis of rhinosporidiosis, often supported by biopsy findings demonstrating characteristic sporangia. This applies to cases involving any affected site, such as nasal polyps, conjunctival lesions, or cutaneous manifestations. Ensure the physician's notes clearly state the diagnosis of rhinosporidiosis.

• Do not confuse with other fungal infections or non-infectious polyps; definitive diagnosis is key.
• Consider additional codes for specific anatomical sites of involvement if further specificity is required and documented.
• Ensure pathology reports or physician documentation explicitly identifies Rhinosporidium seeberi or rhinosporidiosis.
