ICD-10: S80.861

The ICD-10 code S80.861 specifically refers to an insect bite (nonvenomous) located on the right lower leg. This code is part of the broader category of superficial injuries, which are classified under Chapter 19 of the ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) that deals with 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 typically result in localized reactions such as redness, swelling, and itching but do not lead to severe systemic reactions or complications associated with venomous bites.

Symptoms

The clinical presentation of a nonvenomous insect bite may include:
- Localized swelling: The area around the bite may become swollen due to inflammation.
- Erythema: Redness at the site of the bite is common.
- Pruritus: Itching is a frequent symptom, which can lead to scratching and potential secondary infections.
- Pain or tenderness: Mild pain may be experienced at the site of the bite.

Diagnosis

Diagnosis is primarily clinical, based on the history of exposure to insects and the characteristic appearance of the bite. Healthcare providers may consider:
- Patient history: Inquiry about recent outdoor activities or exposure to areas where insects are prevalent.
- Physical examination: Assessment of the bite site for signs of infection or allergic reaction.

Treatment

Management of nonvenomous insect bites typically involves:
- Symptomatic relief: Antihistamines may be used to alleviate itching, while topical corticosteroids can reduce inflammation.
- Cold compresses: Applying a cold pack can help reduce swelling and discomfort.
- Prevention of secondary infection: Keeping the area clean and avoiding scratching is crucial.
