ICD-10 Code B87.8 – Myiasis of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B87.8 – Myiasis of other sites
What it is
B87.8 identifies myiasis involving body sites not classified elsewhere. Use it when larvae infest tissue outside the more specific ICD-10 categories, and the record clearly supports that location.
Clinical signs
Findings may include visible larvae, painful or draining skin lesions, swelling, or a sensation of movement in the affected area. Clinical features vary; refer to documentation.
When to use this code
Use B87.8 when the clinician documents myiasis at an unspecified or other named site that does not fit a more specific code. It is appropriate when the site is described clearly enough to support “other sites,” such as an unusual wound or tissue location. Confirm the chart does not identify a different myiasis category.
Do not use for
Do not use this code if the record specifies another myiasis code or only documents a suspected infestation without confirmation. Check documentation for the exact site and organism details.
Coding tip
Verify the anatomic site first; if a more specific myiasis code applies, report that code instead of B87.8.
