Herpesviral [herpes simplex] infections (B00)

Browse all the diagnosis codes used for herpesviral [herpes simplex] infections (b00). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Dual Specificity Phosphatase 3 - A dual specificity phosphatase subtype that plays a role in intracellular signal transduction by inactivating MITOGEN-ACTIVATED PROTEIN KINASES. It has specificity for EXTRACELLULAR SIGNAL-REGULATED MAP KINASES.

Encephalitis, Herpes Simplex - An acute (or rarely chronic) inflammatory process of the brain caused by SIMPLEXVIRUS infections which may be fatal. The majority of infections are caused by human herpesvirus 1 (HERPESVIRUS 1, HUMAN) and less often by human herpesvirus 2 (HERPESVIRUS 2, HUMAN). Clinical manifestations include FEVER; HEADACHE; SEIZURES; HALLUCINATIONS; behavioral alterations; APHASIA; hemiparesis; and COMA. Pathologically, the condition is marked by a hemorrhagic necrosis involving the medial and inferior TEMPORAL LOBE and orbital regions of the FRONTAL LOBE. (From Adams et al., Principles of Neurology, 6th ed, pp751-4)

Herpes Genitalis - Infection of the genitals (GENITALIA) with HERPES SIMPLEX VIRUS in either the males or the females.

Herpes Labialis - Herpes simplex, caused by type 1 virus, primarily spread by oral secretions and usually occurring as a concomitant of fever. It may also develop in the absence of fever or prior illness. It commonly involves the facial region, especially the lips and the nares. (Dorland, 27th ed.)

Herpes Simplex - A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)

Herpes Simplex Virus Protein Vmw65 - Trans-acting protein that combines with host factors to induce immediate early gene transcription in herpes simplex virus.

Herpes Simplex Virus Vaccines - Vaccines or candidate vaccines used to prevent infection with viruses from the genus SIMPLEXVIRUS. This includes vaccines for HSV-1 and HSV-2.

Herpesvirus 1, Human - The type species of SIMPLEXVIRUS causing most forms of non-genital herpes simplex in humans. Primary infection occurs mainly in infants and young children and then the virus becomes latent in the dorsal root ganglion. It then is periodically reactivated throughout life causing mostly benign conditions.

Herpesvirus 2, Human - A species of SIMPLEXVIRUS associated with genital infections (HERPES GENITALIS). It is transmitted by sexual intercourse and close personal contact.

Keratitis, Herpetic - A superficial, epithelial Herpesvirus hominis infection of the cornea, characterized by the presence of small vesicles which may break down and coalesce to form dendritic ulcers (KERATITIS, DENDRITIC). (Dictionary of Visual Science, 3d ed)

Simplexvirus - A genus of the family HERPESVIRIDAE, subfamily ALPHAHERPESVIRINAE, consisting of herpes simplex-like viruses. The type species is HERPESVIRUS 1, HUMAN.

Smallpox Vaccine - A VACCINIA VIRUS vaccine used for immunization against SMALLPOX. It is now recommended only for laboratory workers exposed to SMALLPOX VIRUS. Certain countries continue to vaccinate those in the military service. Rare complications most often associated with older generation smallpox vaccines include VACCINIA, secondary bacterial infections, and ENCEPHALOMYELITIS. Because MONKEYPOX VIRUS and SMALLPOX VIRUS are both ORTHOPOXVIRUS and are closely related smallpox vaccines provide effective CROSS-PROTECTION against MONKEYPOX (https://www.cdc.gov/poxvirus/monkeypox/clinicians/smallpox-vaccine.html).

Stomatitis, Herpetic - Stomatitis caused by Herpesvirus hominis. It usually occurs as acute herpetic stomatitis (or gingivostomatitis), an oral manifestation of primary herpes simplex seen primarily in children and adolescents.

Vaccinia - The cutaneous and occasional systemic reactions associated with vaccination using smallpox (variola) vaccine.

Vaccinia virus - The type species of ORTHOPOXVIRUS, related to COWPOX VIRUS, but whose true origin is unknown. It has been used as a live vaccine against SMALLPOX. It is also used as a vector for inserting foreign DNA into animals. Rabbitpox virus is a subspecies of VACCINIA VIRUS.

Instructional Notations

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.

• congenital herpesviral infections P35.2

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

• anogenital herpesviral infection A60
• gammaherpesviral mononucleosis B27.0
• herpangina B08.5
