Lower respiratory tract infection, acute infectious
|Dx:||Lower respiratory tract infection, acute infectious|
|APACHE Como Component:||none|
|APACHE Acute Component:||2019-0: Respiratory Infection|
|External ICD10 Documentation|
This diagnosis is a part of ICD10 collection.
Includes ACUTE infectious:
- 1) Bronchitis -- inflammation of the bronchi, in this case due to infection
- 2) Bronchiolitis -- inflammation of the bronchioles (small, distal bronchi), in this case due to infection
- But it does not include Bronchiolitis obliterans organizing pneumonia (BOOP, cryptogenic organizing pneumonia (COP)), which is an immune-mediated, not infectious, entity
- 3) Tracheobronchitis,
- Any combination of #1, #2 and #3
- The could be confusion about what is "upper" vs. "lower" respiratory.
- Remember from top to bottom, the anatomy is: oropharynx --> larynx --> trachea --> main carina --> bronchi --> smaller bronchi and then bronchioles --> alveoli.
- For ICD10 coding, the answer is anything above and including the main carina at the bottom of the trachea is "upper" and everything below that is "lower". So, while a pure tracheitis or laryngitis is upper, a tracheobronchitis includes part of lower airway and thus is categorized as lower.
- Regarding chronic infections of lower respiratory tract:
- For involvement limited to airways/bronchi, use one of:
- For chronic alveolar infection (i.e. pneumonia) there is NOT a specific distinction in the codes between acute and chronic. HOWEVER, true chronic pneumonias are rare in immunocompetent patients unelss they're due to indolent bugs, such as certain fungi, parasites, and TB.
Alternate ICD10s to consider coding instead or in addition
- Bronchitis, acute or chronic not specified, infectious or noninfectious (lower respiratory problem)
- Bronchitis, chronic, infectious or noninfectious (lower respiratory problem)
- Disorder of upper respiratory tract, infectious or noninfectious NOS
- Upper respiratory infection, acute NOS
|Lower respiratory tract infection codes:|
Candidate Combined ICD10 codes
Infections in ICD10 have combined coding requirements for some of their pathogens. Any that have antibiotic resistances would store those as Combined ICD10 codes as well. If the infection is acquired in the hospital, see Nosocomial infection, NOS. See Lab and culture reports for confirmation and details about tests. See Infections in ICD10 for more general info.
