B74.2

What This Code Means

This is a parasitic infection caused by a specific type of worm called Brugia timori that lives in the lymphatic system and tissues under the skin. The infection is transmitted through mosquito bites and can cause swelling, inflammation, and discomfort in affected areas.

Coding Tips

• •Verify the specific Brugia species (timori vs. malayi) is documented in the medical record, as B74.2 is specific to Brugia timori only
• •This code requires a 5th character extension to specify laterality (right, left, or bilateral) if applicable to the affected lymphatic vessels or nodes
