Malayan filariasis

This code represents Malayan filariasis, also known as Brugian filariasis, a parasitic infection caused by the nematodes Brugia malayi or Brugia timori. The disease is characterized by lymphatic dysfunction, leading to lymphedema, elephantiasis, and acute inflammatory episodes.

Use this code for confirmed diagnoses of Malayan filariasis, typically identified through microscopic examination of blood smears for microfilariae or serological testing. It is appropriate for patients presenting with symptoms such as fever, lymphadenitis, funiculitis, epididymitis, or early signs of lymphedema in endemic areas.

• Ensure documentation specifies "Malayan" or "Brugian" filariasis to differentiate from other forms of filariasis.
• Code any associated manifestations, such as lymphedema or elephantiasis, as secondary diagnoses.
• Distinguish from Wuchereria bancrofti filariasis, which is coded elsewhere.
