Infections in ICD10

Infections in ICD10 are coded somewhat inconsistently. There are #Diagnoses where the pathogen is implied and [[[#Diagnoses where the pathogen must be coded separately]]. #Coding Antibiotic Resistance should also be done when there is one.

Diagnoses where the pathogen is implied

Some infections are coded as single codes that imply the pathogen:

Infection with implied pathogen codes:
AIDS (disease due to HIV) Actinomyces (actinomycosis) African trypanosomiasis Amoebiasis (amoebic dysentery due to Entamoeba histolytica) Arthritis, due to Lyme Arthritis, due to tuberculosis Bone, tuberculosis (tuberculous osteomyelitis) Botulism (due to Clostridium botulinum toxin) Chagas' disease (due to American trypanosomiasis) Chlamydia psittici infection Cholera (due to Vibrio cholerae) Clostridium difficile infection (C. diff) Creutzfeldt-Jakob disease Dengue fever (due to Dengue virus) Diptheria (due to Corynebacterium diphtheriae toxin) German measles, limited to skin HIV infection, asymptomatic Hantavirus infection Helicobacter pylori (H. pylori) Helminthic (parasitic worm) infection, any organ(s) Hepatitis A, acute Hepatitis B, acute Hepatitis B, chronic Hepatitis C, acute Hepatitis C, chronic Infectious contact/exposure, HIV, without disease (yet) Infectious contact/exposure, rabies, without disease (yet) Infectious contact/exposure, tuberculosis, without disease (yet) Infestation, NOS Influenza pneumonia Influenza with nonrespiratory manifestations Influenza without pneumonia but with other respiratory manifestations Leprosy (due to Mycobacterium leprae) (Hansen's disease) Lyme disease OR for buglist Borrelia burgdorferi or B. mayonii Lyme meningitis (due to Borrelia burgdorferi or Borrelia mayonii) Malaria (due to Plasmodia, any type) Measles, limited to skin Molluscum contagiosum Mumps Nocardia (nocardiosis) Observation for SUSPECTED tuberculosis Poliomyelitis, acute Rabies OR for buglist rabies virus Rickettsia infection SARS (severe acute respiratory syndrome) Salmonella enteritis Scarlet fever Shigellosis (dysentery due to Shigella species) Smallpox (due to Variola viruses) Spine, tuberculosis (Pott's disease) Staphylococcal scalded skin syndrome Subacute sclerosing panencephalitis (SSPE) (caused by Measles virus) Tetanus infection (due to toxoid of Clostridium tetani) Thrush (Candida infection of mouth) Toxoplasmosis OR for buglist Toxoplama gondii Tuberculosis of the nervous system Tuberculosis of the respiratory system, confirmed Typhoid fever or Paratyphoid fever (due to Salmonella typhi or Salmonella enterica) Whooping cough (Pertussis) (due to Bordetella pertussis) Yellow fever (caused by yellow fever virus)

Diagnoses where the pathogen must be coded separately

Some infections need to be coded as Combined ICD10 codes of the condition and the pathogen. For example, Pneumonia, bacterial and Streptococcus pneumoniae.

Infection requiring pathogen codes:

Coding Antibiotic Resistance

Antibiotic resistance is combined-coded, see Antibiotic Resistant Organism for more info.
