Code Classification

  • External causes of morbidity and mortality
    (V01–Y99)
    • Legal intervention, operations of war, military operations, and terrorism
      (Y35-Y38)
      • Operations of war
        (Y36)

Y36.91 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of war operations involving unspecified weapon of mass destruction [wmd]. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Unspecified diagnosis codes like Y36.91 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding Applicable to War operations involving unsp weapon of mass destruction

Non-specific codes like Y36.91 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for war operations involving unsp weapon of mass destruction:

  • Use Y36.91XA for initial encounter - BILLABLE CODE

  • Use Y36.91XD for subsequent encounter - BILLABLE CODE

  • Use Y36.91XS for sequela - BILLABLE CODE

Biodefense and Bioterrorism

A bioterrorism attack is the deliberate release of viruses, bacteria, or other germs to cause illness or death. These germs are often found in nature. But they can sometimes be made more harmful by increasing their ability to cause disease, spread, or resist medical treatment.

Biological agents spread through the air, water, or in food. Some can also spread from person to person. They can be very hard to detect. They don't cause illness for several hours or days. Scientists worry that anthrax, botulism, Ebola and other hemorrhagic fever viruses, plague, or smallpox could be used as biological agents.

Biodefense uses medical measures to protect people against bioterrorism. This includes medicines and vaccinations. It also includes medical research and preparations to defend against bioterrorist attacks.

Chemical Emergencies

When a hazardous chemical has been released, it may harm people's health. Chemical releases can be unintentional, as in the case of an industrial accident. They could also be planned, as in the case of a terrorist attack with a chemical weapon.

Some hazardous chemicals have been developed by military organizations for use in warfare. Examples are nerve agents such as sarin and VX. Many hazardous chemicals are used in industry - for example, chlorine, ammonia, and benzene. Some can be made from everyday items such as household cleaners.

Although there are no guarantees of safety during a chemical emergency, you can take actions to protect yourself. You should have a disaster plan. Being prepared can help reduce fear, anxiety, and losses. If you do experience a disaster, it is normal to feel stressed. You may need help in finding ways to cope.

Radiation Emergencies

Radiation is a type of energy. People are exposed to small amounts of radiation every day from sources such as sunlight. A radiation emergency would involve larger amounts of radiation and could be caused by:

  • Dirty bombs - a mix of explosives with radioactive powder
  • Fallout from a nuclear bomb
  • Accidental release from a nuclear reactor or a nuclear weapons plant

A lot of radiation over a short period can cause burns or radiation sickness. If the exposure is large enough, it can cause premature aging or even death.

Although there are no guarantees of safety during a radiation emergency, you can take actions to protect yourself. You should have a disaster plan. Being prepared can help reduce fear, anxiety and losses. If you do experience a disaster, it is normal to feel stressed. You may need help in finding ways to cope.
