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
- culture results might be negative if antibiotics were started before the sample was taken; you can still code this with a pathogen of Infectious organism, unknown
- 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.
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.
