B08 is a non-billable ICD-10-CM category code for other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified, so it cannot be submitted on claims. Use a more specific code from this category instead, such as B08.010, B08.011, B08.02, and B08.03.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to B08: its own notes plus those printed at Chapter 1. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

From Chapter 1 (A00-B99) Certain infectious and parasitic diseases applies to 1,068 codes
  • diseases generally recognized as communicable or transmissible

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • vesicular stomatitis virus disease (A93.8)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 1 (A00-B99) Certain infectious and parasitic diseases applies to 1,068 codes
  • carrier or suspected carrier of infectious disease (Z22.-)
  • certain localized infections - see body system-related chapters
  • infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
  • infectious and parasitic diseases specific to the perinatal period (P35-P39)
  • influenza and other acute respiratory infections (J00-J22)

Use Additional Code

Skin Infections

Your skin is your body's largest organ. It has many different functions, including covering and protecting your body. It helps keep germs out. But sometimes the germs can cause a skin infection. It often happens when the germs enter your body through a break, cut, or wound on your skin.

  • What are skin infections?

  • Who is more likely to get a skin infection?
  • What are the symptoms of skin infections?

Questions About B08Overview

Is B08 a billable code?

No. This is a category header that groups the codes for other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified, and headers cannot be submitted on claims. Claims for other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified need a more specific code from this category, such as B08.010, B08.011, and B08.02.

Can B08 be reported with A93.8?

Not as a rule. The Excludes1 note on B08 lists "vesicular stomatitis virus disease (A93.8)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
