Additional Info
- T. pallidum is a spirochete, a spiral-shaped bacterium.
- It is the cause of syphilis, including any of it's acute, chronic and congenital forms, involving any organ(s).
STD Coding Guidelines
- Coding of an STD involves combining a code for the infection, with the relevant pathogen.
- For the infection, choose a code indicating an infection of that body part
- e.g. for CNS syphilis would use: Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, bacterial combined with the bug code
- e.g. for the "usual" cutaneous manifestation of many STDs, combine Sexually transmitted (venereal) infections, NOS with the bug code.
- Pathogen choices for STDs would include:
- The three major specific ones are:
- If it's not one of those 3, then other options for pathogen include:
Alternate ICD10s to consider coding instead or in addition
- Sexually transmitted (venereal) infections, NOS
- Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, infectious NOS
- Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, bacterial
- Skin, rash NOS
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.
