The ICD-10 code S90.46 specifically refers to an insect bite (nonvenomous) of the toe. To diagnose this condition accurately, healthcare providers typically follow a set of criteria that includes clinical evaluation, patient history, and sometimes additional diagnostic tests. Below are the key criteria used for diagnosis:

Clinical Evaluation

1. Physical Examination:
   - The healthcare provider will conduct a thorough examination of the affected toe, looking for signs of an insect bite, such as redness, swelling, and localized pain.
   - The presence of a puncture wound or other marks that suggest an insect bite may be noted.

2. Symptoms Assessment:
   - Patients may report symptoms such as itching, swelling, and tenderness in the area of the bite.
   - Systemic symptoms (e.g., fever, malaise) are generally absent in nonvenomous bites but should be assessed to rule out other conditions.

Patient History

1. Exposure History:
   - The provider will inquire about recent outdoor activities or exposure to areas where insect bites are common, such as gardens, parks, or wooded areas.
   - A detailed history of the incident, including the time and place of the bite, can help in identifying the cause.

2. Allergy History:
   - It is important to assess whether the patient has a history of allergic reactions to insect bites, which may complicate the diagnosis and treatment.

Differential Diagnosis

1. Ruling Out Other Conditions:
   - The provider must differentiate between insect bites and other potential causes of toe symptoms, such as infections, allergic reactions, or dermatological conditions.
   - Conditions like cellulitis, abscesses, or other skin infections should be considered and ruled out through clinical judgment.

Additional Diagnostic Tests

1. Laboratory Tests:
   - In most cases of nonvenomous insect bites, laboratory tests are not necessary. However, if there are signs of infection or if the symptoms persist, a complete blood count (CBC) or cultures may be ordered to assess for secondary infections.

2. Imaging Studies:
   - Imaging is rarely required for insect bites unless there is suspicion of deeper tissue involvement or complications.
