ICD-10: S50.862

The ICD-10 code S50.862 specifically refers to an insect bite (nonvenomous) of the left forearm. This code is part of the broader category of injuries related to insect bites, which are classified under Chapter 19 of the ICD-10 coding system, focusing on injuries, poisoning, and certain other consequences of external causes.

Clinical Description

Definition

An insect bite (nonvenomous) is defined as a skin injury caused by the bite of an insect that does not introduce venom into the body. Common examples include bites from mosquitoes, fleas, and certain types of flies. 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 and tender.
- Redness: Erythema is common at the site of the bite.
- Itching: Pruritus is often reported, leading to scratching and potential secondary infections.
- Pain: Mild to moderate pain may occur, particularly if the bite is scratched.

Diagnosis

Diagnosis of an insect bite is primarily clinical, based on the patient's history and physical examination. Key factors include:
- History of exposure: Recent outdoor activities or contact with infested areas.
- Physical examination: Inspection of the bite site for signs of inflammation or infection.
- Differential diagnosis: Exclusion of other conditions such as allergic reactions, infections, or bites from venomous insects.
