Mansonelliasis

Mansonelliasis is a parasitic infection caused by filarial nematodes of the genus Mansonella. These infections are typically asymptomatic but can manifest with non-specific symptoms such as arthralgia, pruritus, fever, and lymphadenopathy. The parasites are transmitted by biting midges or blackflies.

Use this code for a confirmed diagnosis of mansonelliasis, typically identified through microscopic examination of blood smears or skin snips for microfilariae. This code is appropriate when the physician's documentation explicitly states mansonelliasis as the causative agent of the patient's symptoms or as an incidental finding.

• Ensure the documentation specifies Mansonella infection; do not use for other filarial infections.
• If specific symptoms are documented, code those symptoms in addition to the parasitic infection.
• Confirm the diagnosis is definitively established, not merely suspected, before assigning this code.
