ICD-10 Code B88 – Other infestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B88 – Other infestations
What it is
B88 covers infestations by organisms that do not fit a more specific ICD-10 category. Use it for parasitic or arthropod-related conditions when the chart documents “other infestations” or a similar nonspecific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include itching, skin irritation, visible organisms, or signs of infestation on exam, but you should code only what is clearly documented.
When to use this code
Use B88 when the provider identifies an infestation but does not name a more specific codeable condition. It may apply when the record describes an unspecified or unusual infestation that is not classified elsewhere. Check documentation for the organism, site, and whether a more precise code exists.
Do not use for
Do not use B88 if the chart supports a specific infestation code, such as scabies or pediculosis. Avoid it when the condition is better classified as dermatitis, infection, or another defined diagnosis.
Coding tip
Before assigning B88, search the note for a specific organism or named infestation that would support a more exact code.
