Additional Info
Includes: peritoneal abscess/abdominal abscess/pelvic abscess
AKA Spontaneous bacterial peritonitis (SBP)
- often abdominal paracentesis is done to test the fluid for WBC and cultures
- A diagnosis of SBP is made if the polymorphonuclear cell (PMN, also referred to as neutrophils) count in the ascitic fluid is ≥250 cells/mm3, culture results are positive, and secondary causes of peritonitis are excluded
- Spontaneous bacterial peritonitis is the development of a bacterial infection in the peritoneum causing peritonitis, despite the absence of an obvious source for the infection. It occurs almost exclusively in people with portal hypertension, usually as a result of cirrhosis of the liver. It can also occur in patients with nephrotic syndrome. I put in this clarification because there is a distinction between SBP and just peritonitis. --LKolesar 07:58, 2018 May 30 (CDT)
- I have a question many doctors put pts on antibiotics on spec for SBP even though NO tap /culture was done prior to antibiotics. Then a few days later a tap was done /the culture was negative. my question is do you code SBP /negative culture or do you only code SBP if a culture was done prior to antibiotics and the results come back positive. and or become positive during their stay in the hospital. And just ignore the fact that antibiotics were ordered for a diagnosis that could or couldnt be there.????
- Any culture taken after antibiotics have already been started is not going to be helpful for the diagnosis, especially if negative. If the doctors are calling it SBP because of other clinical parameters (fever, abd pain, PD pt, ultrasounds , WBC, etc), then I would call it peritonitis if no other cause is found for the other symptoms and it is being treated. --LKolesar 13:33, 2014 October 14 (CDT)
- I think the question was which entry to use as pathogen. Also, I think this question is much more general than just for Peritonitis. Is it a special case for No Culture Sent or Resulted? If so, could someone summarize this to there and link it from here? We'd want to word it to use the same words that a collector who searches for this next time would be likely to use. I would do it myself but would like someone medical to make sure I am not misunderstanding this, and you guys have a better idea what you would search for in such a situation...

- I think the data collectors know how to code a pathogen or not and if the pt has been on antibiotics prior to the culture, then usually the culture will be negative. The question was whether to code peritonitis even if the cultures are negative. This question can be asked of any infectious diagnosis. You have to look at the entire clincial picture and the certainty of the doctors in making the diagnosis. Culture results alone are inadequate to making a diagnosis for various reasons. They can affirm a diagnosis but are never a separate entity. --LKolesar 11:22, 2014 October 20 (CDT)
- so we agree that this is about more than just peritonitis. I take your point about the pathogen part. So, does anyone have a suggestion how they would search for it in a way that is not DX specific? Because this question must be an FAQ and I want to make sure the answer can be found. So this is a question to anyone out there - how would you search for this answer on the wiki? Ttenbergen
- Would it be appropriate to move this to Infections in ICD10? Would it still address the issue? Ttenbergen 22:24, 2018 May 29 (CDT)
- Any culture taken after antibiotics have already been started is not going to be helpful for the diagnosis, especially if negative. If the doctors are calling it SBP because of other clinical parameters (fever, abd pain, PD pt, ultrasounds , WBC, etc), then I would call it peritonitis if no other cause is found for the other symptoms and it is being treated. --LKolesar 13:33, 2014 October 14 (CDT)
Alternate ICD10s to consider coding instead or in addition
Candidate Combined ICD10 codes
Infections
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.
Possible Simultaneous Presence of Multiple Different Types of Infection in a Single Site
- This refers to the situation where there may be simultaneous infection with multiple types of organisms -- e.g. 2 of bacteria, virus, fungus. While a classic example is a proven viral pneumonia (e.g. influenza) with a suspected/possible bacterial pneumonia superimposed, this kind of thing can occur in places other than the lungs, e.g. meningitis.
- The "signature" of this is typically the patient being treated simultaneously with antimicrobial agents for multiple types of organisms. BUT don't confuse this with there being infections at DIFFERENT body sites.
- As per our usual practice, we will consider a diagnosis as present if the clinical team thinks it's present and are treating it, with the exception that the team initially treated for the possible 2nd type of infection but then decided it likely was NOT present and stopped those agents.
- And remember that Infectious organism, unknown is used when the the specific organism is unknown (this could be not knowing the TYPE of organism, or suspecting the type but not having identified the specific organism of that type), while when the organism has been identified but it's not in our bug list, THEN use Bacteria, NOS, Virus, NOS or Fungus or yeast, NOS.
Attribution of infections
| cirrhosis codes: |
- if coding cirrhosis also code cause of cirrhosis if known
