ICD-10: S90.561

The ICD-10 code S90.561A refers specifically to an insect bite (nonvenomous) located on the right ankle. This code is part of the broader classification system used for diagnosing and coding various medical conditions, particularly in the context of healthcare billing and record-keeping.

Clinical Description

Definition

An insect bite (nonvenomous) is defined as a skin injury caused by the bite of an insect that does not inject venom into the body. Common examples include bites from mosquitoes, flies, and certain types of beetles. These bites can lead to localized reactions, including redness, swelling, and itching, but typically do not result in severe systemic reactions.

Symptoms

Patients with a nonvenomous insect bite may experience:
- Localized swelling: The area around the bite may become swollen.
- Redness: The skin may appear red and inflamed.
- Itching: A common symptom that can lead to scratching, potentially causing secondary infections.
- Pain or discomfort: Mild pain may be present at the site of the bite.

Diagnosis

Diagnosis of an insect bite is primarily clinical, based on the patient's history and physical examination. The healthcare provider will assess the bite's appearance, the patient's symptoms, and any potential exposure to insects. In some cases, a detailed history of the patient's activities prior to the bite may be necessary to identify the insect involved.
