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.
  • Bronchitis NOS
  • Bronchitis with tracheitis NOS
  • Catarrhal bronchitis
  • Tracheobronchitis NOS

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:
  • exposure to environmental tobacco smoke Z77.22
  • exposure to tobacco smoke in the perinatal period P96.81
  • history of tobacco dependence Z87.891
  • occupational exposure to environmental tobacco smoke Z57.31
  • tobacco dependence F17
  • tobacco use Z72.0

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 bronchitis J20
  • allergic bronchitis NOS J45.909
  • asthmatic bronchitis NOS J45.9
  • bronchitis due to chemicals, gases, fumes and vapors J68.0

Patient Education


Bronchial Disorders

When you breathe in, the air travels down through your trachea (windpipe). It then goes through two tubes to your lungs. These tubes are your bronchi. Bronchial disorders can make it hard for you to breathe.

The most common problem with the bronchi is bronchitis, an inflammation of the tubes. It can be acute or chronic. Other problems include:

  • Bronchiectasis - a condition in which damage to the airways causes them to widen and become flabby and scarred
  • Exercise-induced bronchospasm - a breathing problem that happens when your airways shrink while you are exercising
  • Bronchiolitis - an inflammation of the small airways that branch off from the bronchi
  • Bronchopulmonary dysplasia - a chronic lung condition in infants, most often premature infants

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.
