ICD-10: S90.466

The ICD-10-CM code S90.466 refers to an insect bite (nonvenomous) that affects the unspecified lesser toe(s). This code is part of the broader category of injuries related to insect bites, which are classified under Chapter 19 of the ICD-10-CM, specifically focusing on injuries, poisoning, and certain other consequences of external causes.

Clinical Description

Definition

An insect bite is a puncture wound caused by the bite of an insect, which can lead to various symptoms depending on the type of insect and the individual's reaction. Nonvenomous insect bites typically do not cause severe systemic reactions but can result in localized symptoms.

Symptoms

Common symptoms associated with nonvenomous insect bites include:
- Redness and swelling: The area around the bite may become inflamed.
- Itching: A common reaction that can lead to scratching and potential secondary infections.
- Pain or discomfort: Mild to moderate pain may be experienced at the site of the bite.
- Localized warmth: The affected area may feel warm to the touch.

Affected Area

In the case of S90.466, the bite specifically affects the lesser toe(s), which are the smaller toes on the foot. This can include any of the toes excluding the big toe, and the symptoms may be localized to one or more of these toes.

Diagnosis and Coding

When diagnosing an insect bite, healthcare providers typically assess the patient's history, the appearance of the bite, and any accompanying symptoms. The use of S90.466 is appropriate when the bite is confirmed to be nonvenomous and the specific toe(s) affected are not identified.

Coding Guidelines

• S90.466 is used when the insect bite is nonvenomous and affects the lesser toe(s) without further specification.
• If the bite were to cause more severe reactions or involve venomous insects, different codes would be applicable.
