Individuals can search for the diagnosis codes for insect bite infections at ICD9Data.com, a website that provides medical codes listed in the International Classification of Diseases, as of early 2015. Individuals can also search for these codes on the Centers for Medicare & Medicaid Services website, CMS.gov.
The ICD is published by the World Health Organization and provides codes that doctors use for billing purposes to specify the condition treated, as explained by the Centers for Disease Control and Prevention. The search feature on ICD9Data.com allows users to search different versions of the ICD manual. The ICD-9 manual lists the appropriate codes for a bug bite infection between 910 and 919.
Different codes for bug bite infections cover bites on different areas of the body, including the face, trunk, shoulder, elbow, and foot, according to the Centers for Medicare & Medicaid Services. For example, the ICD code for a nonvenomous insect bite on the foot is 917. Codes for a bug bite with infection end with a five, while bites without an infection end with a four. For example, the code for an insect bite on the foot with an infection is 917.5, whereas a bite in the same location without an infection is coded as 917.4.
