Other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified (B08) ICD-10-CM
The B08 code range covers other viral infections characterized by skin and mucous membrane lesions, not elsewhere classified with 28 ICD-10-CM diagnosis codes. 22 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the B08 range.
Cowpox
A mild, eruptive skin disease of milk cows caused by COWPOX VIRUS, with lesions occurring principally on the udder and teats. Human infection may occur while milking an infected animal.
Erythema Infectiosum
Contagious infection with HUMAN PAROVIRUS B19 most commonly seen in school age children and characterized by fever, headache, and rashes of the face, trunk, and extremities. It is often confused with RUBELLA.
Exanthema Subitum
An acute, short-lived, viral disease of infants and young children characterized by a high fever at onset that drops to normal after 3-4 days and the concomitant appearance of a macular or maculopapular rash that appears first on the trunk and then spreads to other areas. It is the sixth of the classical exanthematous diseases and is caused by HHV-6; (HERPESVIRUS 6, HUMAN). (From Dorland, 27th ed)
Herpangina
Acute types of coxsackievirus infections or ECHOVIRUS INFECTIONS that usually affect children during the summer and are characterized by vesiculoulcerative lesions on the MUCOUS MEMBRANES of the THROAT; DYSPHAGIA; VOMITING, and FEVER.
Molluscum Contagiosum
A common, benign, usually self-limited viral infection of the skin and occasionally the conjunctivae by a poxvirus (MOLLUSCUM CONTAGIOSUM VIRUS). (Dorland, 27th ed)
About the B08 Code Range
These viral infections have lesions on the skin and mucous membranes, the moist linings of the body, and are not classified elsewhere.
The subdivisions separate named conditions and virus groups. B08.0 includes cowpox, vaccinia not from vaccine, orf, pseudocowpox and paravaccinia. B08.6 and B08.7 separate parapoxvirus and yatapoxvirus infections into named and unspecified types.
Other subdivisions name molluscum contagiosum, fifth disease, and enteroviral conditions of the mouth or throat. B08.2 separates sixth disease by whether human herpesvirus 6, human herpesvirus 7, or no specific virus is named. B08.8 covers other specified infections with skin and mucous membrane lesions.
