ICD-10 Code B87.0 – Cutaneous myiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B87.0 – Cutaneous myiasis
What it is
B87.0 identifies cutaneous myiasis, an infestation of the skin by fly larvae. Use it when documentation states larvae are present in skin lesions or under the skin.
Clinical signs
Common findings include a painful or itchy skin lesion, swelling, and a central opening that may drain fluid. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents cutaneous myiasis, including furuncular or wound-related infestation of the skin. It may also apply when a clinician confirms larvae in a skin lesion. Check documentation if the site or type of myiasis is unclear.
Do not use for
Do not use B87.0 for intestinal, nasal, or other noncutaneous myiasis. If the record only notes an insect bite, wound infection, or foreign body without larvae, check documentation.
Coding tip
Code the specific site only when the provider documents skin involvement and confirm whether a different myiasis code is more appropriate.
