ICD-10 Code B88.8 – Other specified infestations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B88.8 – Other specified infestations
What it is
B88.8 identifies infestations caused by organisms or parasitic conditions that do not fit a more specific ICD-10 code. Use it when the record clearly documents an infestation, but the exact type is not named or is outside other listed categories.
Clinical signs
Clinical features vary; refer to documentation. Findings may include pruritus, skin irritation, visible organisms, or lesions consistent with infestation, but the specific cause should be documented if known.
When to use this code
Use B88.8 when the clinician documents an infestation and no more specific code applies. It is appropriate for unusual, unspecified, or otherwise classified parasitic infestations recorded in the medical note. If the organism is identified elsewhere in the chart, code that specific diagnosis instead.
Do not use for
Do not use this code when the infestation is better described by a more specific ICD-10 code, such as scabies or pediculosis. Also avoid it for dermatitis, itching, or rash without documented infestation.
Coding tip
Review the note for the exact organism or infestation type before assigning B88.8.
