Additional Info

• Despite its name, this entity is NOT an infection. It is fundamentally a chemical pneumonitis, which CAN become secondarily superinfected.
• If an actual lung infection (pneumonia) co-exists with it, you must use this code and a category:pneumonia code as Combined ICD10 codes.
• The reason people often (incorrectly) call it a "aspiration pneumonia" is that a chemical or food aspiration (noninfectious) often has ALL 3 of the cardinal signs of pneumonia: new infiltrate, fever, leukocytosis -- but in the case of aspiration, those manifestations are actually due to chemical irritation (e.g. the hydrochloric acid in the stomach) of the lung.
  • Indeed, though it is very often done, the use of antibiotics to "treat" an aspiration in the early phases when it's almost certainly NOT infected, is not recommended.
• Here are some thoughts about how to figure out whether or not an aspiration event becomes secondarily infected:
  • The usual time course after the aspiration, of development of the lung inflammation and signs related to it, is typically hours to a day or more. And it is considered distinctly RARE for an actual infection due to an aspiration event to develop that quickly.
  • The usual time course of starting to see movement towards resolution of the signs of lung inflammation from noninfected aspiration pneumonitis, in the absence of secondary infection, is a few days. So, when a person who aspirates and is appropriately NOT given antibiotics starts to improve substantially within a few days, we take that as clinical confirmation that it wasn't infected.
  • On the other hand, the most clearcut kind of clinical evidence for secondary infection of a noninfectious aspiration pneumonitis is when the person starts to get better, and then after several days starts to get worse again.
  • The hardest situation in which to determine if a secondary infection has occurred, and whether to start antibiotics, is when the signs of lung inflammation (infiltrate, fever, leukocytosis) doesn't improves and remains bad or worsens.

Inhalation

When substances other than air are inhaled they can cause various problems; if one is present, others might be.

You wanted me to put this on your list so you can review after I rename it. Keep in mind that there is a Template:ICD10 Guideline Inhalation that is called right above here. Most if not all the aspiration pneumonitis info should probably live in there rather than in this page. That template is Template:ICD10_Guideline_Inhalation, transcluded from other pages, so needs to make sense in that context.

JALT I am working on a chart in which a patient develops decreased LOC in ER, and vomits/aspirates and subsequently requires intubation. I have never linked this sort of event to an iatrogenic code in the past, but now I am wondering if I should be linking this to Iatrogenic, complication of medical or surgical care NOS. Any other collectors have thoughts on this?Mlagadi 08:54, 2022 May 24 (CDT) I have not been coding an iatrogenic code with this, although an argument could be made to do so. If they aspirate during intubation then I would use Failed/difficult intubation, or complication of intubation with an iatrogenic code and this code. Lisa Kaita 08:00, 2022 June 3 (CDT) OK, so how should it be coded? Ttenbergen 16:46, 2022 June 15 (CDT)

Alternate ICD10s to consider coding instead or in addition

• Hypersensitivity pneumonitis (extrinsic allergic alveoliltis), NOS
• Radiation pneumonitis (acute or chronic)

Candidate Combined ICD10 codes

• Code associated pneumonia, if it's superimposed on the aspiration.
