ICD-10 Code B86 – Scabies (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B86 – Scabies
What it is
B86 identifies scabies, a contagious skin infestation caused by the human itch mite. It is used when documentation confirms scabies or mite infestation of the skin.
Clinical signs
Common findings include intense itching, often worse at night, and a papular rash. Burrows may be seen in skin folds, wrists, finger webs, or other typical sites; clinical features vary, refer to documentation.
When to use this code
Use B86 when the provider documents scabies as the diagnosis, including suspected or confirmed infestation recorded in the chart. Apply it for outpatient, emergency, or inpatient encounters when the visit is focused on this condition. Check documentation if the note only mentions pruritus or rash without a scabies diagnosis.
Do not use for
Do not use B86 for nonspecific itching, dermatitis, or rash without documented scabies. If the record names another parasitic skin condition, code that diagnosis instead. Check documentation.
Coding tip
Assign B86 only when the provider clearly links the skin findings to scabies.
