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 2026, 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.
Cowpox virus
A species of ORTHOPOXVIRUS that is the etiologic agent of COWPOX. It is closely related to but antigenically different from VACCINIA VIRUS.
Erythema Infectiosum
Contagious infection with human B19 Parvovirus 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.
Molluscipoxvirus
A genus of POXVIRIDAE, subfamily CHORDOPOXVIRINAE, infecting humans. Transmission is by direct contact among children, by sexual contact among young adults, or by fomites. MOLLUSCUM CONTAGIOSUM VIRUS is the type species.
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)
Molluscum contagiosum virus
A species of MOLLUSCIPOXVIRUS causing skin lesions in humans. It is transmitted by direct contact or from non-living reservoirs (fomites), such as books or clothing.
Rubella
An acute infectious disease caused by the RUBELLA VIRUS. The virus enters the respiratory tract via airborne droplet and spreads to the LYMPHATIC SYSTEM.
Vesicular Stomatitis
A viral disease caused by at least two distinct species (serotypes) in the VESICULOVIRUS genus: VESICULAR STOMATITIS INDIANA VIRUS and VESICULAR STOMATITIS NEW JERSEY VIRUS. It is characterized by vesicular eruptions on the ORAL MUCOSA in cattle, horses, pigs, and other animals. In humans, vesicular stomatitis causes an acute influenza-like illness.
Vesicular stomatitis Indiana virus
The type species of VESICULOVIRUS causing a disease symptomatically similar to FOOT-AND-MOUTH DISEASE in cattle, horses, and pigs. It may be transmitted to other species including humans, where it causes influenza-like symptoms.
Vesicular stomatitis New Jersey virus
A species of VESICULOVIRUS causing VESICULAR STOMATITIS primarily in cattle, horses, and pigs. It can be transmitted to humans where it causes influenza-like symptoms.
Vesiculovirus
A genus of the family RHABDOVIRIDAE that infects a wide range of vertebrates and invertebrates. The type species is VESICULAR STOMATITIS INDIANA VIRUS.
About the B08 Code Range
ICD-10 code section B08 covers various viral infections that cause distinctive skin and mucous membrane lesions, which are not classified under other categories. These include conditions from orthopoxvirus, parapoxvirus, and yatapoxvirus families, each identified by unique subcodes like B08.010 for Cowpox and B08.1 for Molluscum contagiosum.
This code section is used to precisely identify and classify infections such as Cowpox (B08.010), also known as paravaccinia, and Molluscum contagiosum (B08.1), a common viral skin infection presenting as small bumps. It also includes Exanthema subitum or sixth disease, caused by human herpesvirus types 6 and 7 (B08.21 and B08.22), as well as viral diseases like erythema infectiosum (fifth disease, B08.3). Additionally, this section captures infections such as parapoxvirus-associated diseases like Orf virus disease (B08.02) and pseudocowpox (B08.03), and yatapoxvirus infections including Tanapox (B08.71). For medical coders searching for the ICD-10 code for viral infections with skin or mucous membrane lesions, B08 codes provide specific classification to support diagnosis, treatment, and billing based on the exact viral cause and clinical presentation.
