Clinical Information

  • 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.
  • Gingivitis, Necrotizing Ulcerative

    an acute or chronic gingivitis characterized by redness and swelling, necrosis extending from the interdental papillae along the gingival margins, pain; hemorrhage, necrotic odor, and often a pseudomembrane. the condition may extend to the oral mucosa; tongue; palate; or pharynx. the etiology is somewhat unclear, but may involve a complex of fusobacterium nucleatum along with spirochetes borrelia or treponema.
  • Noma

    a severe gangrenous process occurring predominantly in debilitated and malnourished children, especially in underdeveloped countries. it typically begins as a small vesicle or ulcer on the gingiva that rapidly becomes necrotic and spreads to produce extensive destruction of the buccal and labial mucosa and tissues of the face, which may result in severe disfigurement and even death. various bacteria have been implicated in the etiology. (dorland, 27th ed)
  • Stomatitis

    inflammation of the soft tissues of the mouth, such as mucosa; palate; gingiva; and lip.
  • Stomatitis, Aphthous

    a recurrent disease of the oral mucosa of unknown etiology. it is characterized by small white ulcerative lesions, single or multiple, round or oval. two to eight crops of lesions occur per year, lasting for 7 to 14 days and then heal without scarring. (from jablonski's dictionary of dentistry, 1992, p742)
  • Stomatitis, Denture

    inflammation of the mouth due to denture irritation.
  • 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.
  • Tumor Protein 63|CUSP|Chronic Ulcerative Stomatitis Protein|Keratinocyte Transcription Factor KET|TP63|Transformation-Related Protein 63|Tumor Protein p73-Like|p40|p51|p63|p73L

    tumor protein 63 (680 aa, ~77 kda) is encoded by the human tp63 gene. this protein plays a role in the mediation of both transcription and limb morphogenesis.
  • Ulcerative Stomatitis

    inflammation of the mouth mucosa associated with the presence of ulcers.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Stomatitis NOS
  • Denture stomatitis
  • Ulcerative stomatitis
  • Vesicular stomatitis

Type 1 Excludes

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.
  • acute necrotizing ulcerative stomatitis A69.1
  • Vincent's stomatitis A69.1

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
