  • Sin Nombre virus encephalitis

Clinical Classification

Clinical Information

  • Hantavirus Pulmonary Syndrome

    acute respiratory illness in humans caused by the sin nombre virus whose primary rodent reservoir is the deer mouse peromyscus maniculatus. first identified in the southwestern united states, this syndrome is characterized most commonly by fever, myalgias, headache, cough, and rapid respiratory failure.

  • Sin Nombre virus

    a species of orthohantavirus which emerged in the four corners area of the united states in 1993. it causes a serious, often fatal pulmonary illness (hantavirus pulmonary syndrome) in humans. transmission is by inhaling aerosolized rodent secretions that contain virus particles, carried especially by deer mice (peromyscus maniculatus) and pinyon mice (p. truei).

  • Hantavirus Pulmonary Syndrome

    an infection caused by hantaviruses. it manifests with flu-like symptoms but it rapidly progresses to life-threatening respiratory problems.

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.
  • Hantavirus disease with pulmonary manifestations
  • Sin nombre virus disease

Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
  • code to identify any associated acute kidney failure N17.9

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.
  • hantavirus disease with renal manifestations A98.5
  • hemorrhagic fever with renal manifestations A98.5

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).

Convert B33.4 to ICD-9-CM

  • ICD-9-CM Code: 079.81 - Hantavirus infection
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Hantavirus Infections

Hantavirus pulmonary syndrome (HPS) is a rare but deadly viral infection. It is spread by mice and rats. They shed the virus in their urine, droppings, and saliva. Tiny droplets with the virus can enter the air. People can get the disease if they breathe infected air or come into contact with rodents or their urine or droppings. You cannot catch it from people.

Early symptoms of HPS include:

  • Fatigue
  • Fever
  • Muscle aches, especially in the thighs, hips and back
  • Headaches
  • Chills
  • Dizziness
  • Nausea, vomiting, diarrhea or abdominal pain

Later symptoms include coughing and shortness of breath.

Controlling rodents in and around your house is the best way to prevent infection. If you have been around rodents and have symptoms of fever, deep muscle aches, and severe shortness of breath, see your doctor immediately.

There is no specific treatment, cure, or vaccine for HPS. Patients may do better if it is recognized early and they get medical care in an intensive care unit. They often need to use a breathing machine and have oxygen therapy.

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.
