Insect Bite ICD-10-CM Codes

What insect bite ICD codes can I use?

You can use numerous insect bite ICD codes, so we selected six insect bite-related ICD-10 codes for this mini-guide. These codes are for non-venomous insect bites, and they are all labeled as initial encounters, which means that patients are receiving active treatment for their insect bites. 

Here are the six codes we picked:

1. S00.06XA - Insect bite (nonvenomous) of scalp, initial encounter

This ICD-10 code is meant to be used on a person confirmed to have been bitten by an insect. The bite is not venomous, and the bite location is the scalp.

2. S00.261A - Insect bite (nonvenomous) of right eyelid and periocular area, initial encounter

This ICD-10 code is the same as Item 1, but this time, the bite location is the right eyelid and periocular area.

3. S00.36XA - Insect bite (nonvenomous) of nose, initial encounter

This ICD-10 code is the same as Item 1, but the bite location is the nose this time.

4. S00.461A - Insect bite (nonvenomous) of right ear, initial encounter

This ICD-10 code is the same as Item 1, but the bite location is the right ear this time.

5. S00.561A - Insect bite (nonvenomous) of lip, initial encounter

This ICD-10 code is the same as Item 1, but the bite location is the lip this time.

6. S10.16XA - Insect bite (nonvenomous) of throat, initial encounter

This ICD-10 code is the same as Item 1, but the bite location is the throat this time.

Which of these insect bite ICD codes are billable?

All of the ones we’ve mentioned are valid and billable ICD-10 codes.

Clinical information about insect bites:

Insect bites can either be venomous or non-venomous. Since all the insect bite ICD codes we mentioned earlier are for non-venomous bites, let’s just talk about non-venomous insect bites.

Examples of insects that have non-venomous bites are mosquitoes, bedbugs, mites, lice, and fleas. Even though their bites are non-venomous, they are still irritating because they tend to leave itchy red spots. Sometimes, these red spots can turn into blisters. Scratching these red spots and blisters can turn into sores that are susceptible to infections.

Sometimes, these insect bites may carry diseases and viruses. An example would be dengue from mosquito bites. Such bites can be treated with antihistamines, ointments, anesthetics, and certain steroids to curb the itchiness of insect bite spots.
