ICD-10 Code B88.1 – Tungiasis [sandflea infestation] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B88.1 – Tungiasis [sandflea infestation]
What it is
Tungiasis is a skin infestation caused by the sand flea, usually affecting the feet or toes. The parasite embeds in the skin and can cause a localized inflammatory reaction.
Clinical signs
Typical findings include a small, painful or itchy papule with a central dark نقط? or opening, often on the feet. Clinical features vary; refer to documentation.
When to use this code
Use B88.1 when the record clearly documents tungiasis or sandflea infestation as the diagnosis. Code it for confirmed infestation, including cases with skin lesions consistent with embedded sand fleas. Check documentation if the note only describes an insect bite or nonspecific dermatitis.
Do not use for
Do not use this code for other parasitic skin infestations, insect bites without tungiasis, or nonspecific pruritic rash. If the chart does not identify sand flea infestation, check documentation.
Coding tip
Assign B88.1 only when the provider names tungiasis or sandflea infestation; do not infer it from location or travel history alone.
