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.
  • War operations involving smoke, fumes, and heat from fires, conflagrations and hot substances

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.
  • war operations involving fires and conflagrations aboard military aircraft Y36.1
  • war operations involving fires and conflagrations aboard military watercraft Y36.0

Patient Education


Veterans and Military Health

Military service members and veterans have made sacrifices to our country, and they face different health issues than civilians. During their service, they are at risk for various injuries. These injuries can happen during combat, while others involve physical stress to the body. Sometimes the injuries are life-threatening or serious enough to cause disability. Others may not be as serious, but can be painful and affect daily life. Specific types of injuries include:

  • Shrapnel and gunshot wounds
  • Lost limbs
  • Head and brain injuries
  • Tinnitus and hearing loss, typically from exposure to noise
  • Sprains and strains
  • Limited range of motion, especially in ankles and knees

There may also be a risk of health problems from exposure to environmental hazards, such as contaminated water, chemicals, infections, and burn pits.

Being in combat and being separated from your family can be stressful. The stress can put service members and veterans at risk for mental health problems. These include anxiety, post-traumatic stress disorder, depression, and substance use. Suicide can also be a concern.
