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.

Different infection types related to Combined ICD10 codes

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:
Abscess of intestine Anus or rectum, abscess Appendicitis, with or without rupture or peritonitis Arthritis, infectious (septic arthritis) Bacteremia Bacterial infection, NOS Bladder, cystitis, acute infectious Bone infection (osteomyelitis), NOS Bone infection (osteomyelitis), acute Bone infection (osteomyelitis), chronic Bursitis, infective (any site) Carrier of infectious disease, unspecified Cellulitis Cholangitis Chronic myringitis Colonized with organism (not infected) Dermatophytosis (tineas, cutaneous fungal infection) Empyema (pyothorax) Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, bacterial Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, infectious NOS Encephalitis, meningoencephalitis, myelitis, encephalomyelitis, viral Endocarditis, infective, acute or subacute Endophthalmitis, infectious Epididymis, infection (epididymitis) Food poisoning (due to foodborne bacterial toxin), NOS Fournier's gangrene Fungemia, NOS Gas gangrene (usually due to Clostridium perfringens) Gastrointestinal infection (gastroenteritis, colitis), bacterial, NOS Gastrointestinal infection (gastroenteritis, colitis), bug NOS Gastrointestinal infection (gastroenteritis, colitis), protozoal, NOS Gastrointestinal infection (gastroenteritis, colitis), viral Iatrogenic, infection, cardiac or vascular prosthetic device or implant or graft NOS Iatrogenic, infection, central venous catheter-related bloodstream infection (CVC-BSI, CLI) Iatrogenic, infection, following a procedure or surgery, NOS Iatrogenic, infection, heart valve prosthesis (incl prosthetic valve endocarditis) Iatrogenic, infection, internal orthopedic prosthetic device or implant or graft or bone device Iatrogenic, infection, internal prosthetic device or implant or graft NOS Iatrogenic, infection, related to vascular access other than central line Iatrogenic, infection, urinary catheter Impetigo Infection of skin or subcutaneous (soft) tissue, NOS Infectious disease NOS Infectious mononucleosis (usually due to Epstein-Barr virus) Intervertebral disc, infection (infective discitis) Kidney infection, acute (pyelonephritis) Kidney infection, chronic (pyelonephritis) Kidney, renal abscess or perinephric abscess Liver abscess Lower respiratory tract infection, acute infectious Mediastinitis, infectious Meningitis, fungal Meningitis, infectious NOS Meningitis, viral - incl West Nile Muscle, infection (pyomyositis, infective myositis) Myocarditis/carditis, acute infective Necrotizing fasciitis Nosocomial infection, NOS Other specified infectious agents as the cause of diseases classified by other ICD10 code Otitis externa, infectious Otitis media, infectious Parasitic infection, NOS Pericarditis, acute, infective Peritonitis, infectious Peritonsillar abscess Pneumonia, NOS Pneumonia, bacterial Pneumonia, fungal/yeast Pneumonia, ventilator-associated (VAP) Pneumonia, viral Prostate, abscess Psoas abscess Puerperal (post-delivery) infections or sepsis Pulmonary embolism (thromboembolism), septic Pulmonary embolism, septic obstetrical thromboembolism Retroperitoneal abscess Septic Thrombosis or Embolism, NOS Severe sepsis Sexually transmitted (venereal) infections, NOS Shock, septic Skin abscess Synovitis, tenosynovitis, infective (any site) Toxic shock syndrome Tracheostomy complication, infection of site Upper respiratory infection, acute NOS Urinary tract infection, NOS Vertebrae, osteomyelitis (bone infection) Viral hemorrhagic fever, NOS Viral hepatitis, acute, NOS Viral hepatitis, chronic, NOS Viral infection, NOS Zoonotic bacterial disease (directly transmitted from animal)

Potential Infections

They can also be coded with diagnoses that can potentially have a pathogen, but don't require one. These are usually disorders that may or may not be infectious in nature.

Potential infection codes:
Abdominal hernia, with gangrene Abortion NOS, with complication Bartholin's gland, disorder, infectious or not Bladder, cystitis NOS Bladder, cystitis, chronic Breast, disorder NOS Breast, inflammatory or infectious disorder of breast Bronchitis, acute or chronic not specified, infectious or noninfectious Bronchitis, chronic, infectious or noninfectious Cervix, inflammatory or infectious disorder Cholecystitis, acute Chronic sinusitis Common cold (acute nasopharyngitis) Conjunctivitis, any type or cause Deep venous thrombosis/thrombophlebitis, leg (DVT) Disorder of anus or rectum, NOS Disorder of eye(s), NOS Disorder of iris or ciliary body of eye Disorder of lacrimal system Disorder of liver, NOS Disorder of nose and/or sinuses, infectious or noninfectious NOS Disorder of peritoneum, NOS Disorder of pulmonary vessels, NOS Disorder of respiratory system, any part, NOS Disorder of salivary glands Disorder of spleen, NOS Disorder of the cardiovascular/circulatory system, NOS Disorder of upper respiratory tract, infectious or noninfectious NOS Diverticulitis, small or large intestine (diverticular disease with perforation or abscess) Diverticulosis, small or large intestine (diverticular disease without perforation or abscess) Duodenitis Endocarditis, infective, chronic Epididymitis or orchitis, NOS (unclear which) Epiglotittis, acute Erythema multiforme Erythema nodosum Esophagitis, NOS Gallbladder or bile duct disorder, NOS Hepatomegaly Internal female reproductive organs and adnexa NOS, inflammatory or infectious disorder Interstitial lung disease, NOS Intracranial abscess Intraspinal abscess Kidney or ureter, disorder NOS Laryngitis or tracheitis, acute Laryngitis or tracheitis, chronic Lung abscess Lymphangitis Male genital organs, disorder NOS Mastoiditis (acute or chronic, infectious or noninfectious) Medical abortion, with complication Meningitis, bacterial, NOS Mouth, cellulitis or abscess Myocarditis, chronic Observation for suspected infection NOS Pancreas disorder, NOS Pancreatitis, acute NOS Penis, disorders NOS Pharyngitis, acute Pleural effusion, NOS Pleurisy (infectious or noninfectious) Progressive Multifocal Leukoencephalopathy (PML) Prostate, disorder NOS Respiratory disorder, postprocedure/postop NOS Retropharyngeal or parapharyngeal abscess Salpingitis, oophoritis or salpingo-oophoritis Sinusitis, acute Skin abscess Skin, rash NOS Spontaneous abortion/miscarriage, with complication Superficial venous thrombosis/thrombophlebitis, anywhere Testis, orchitis Thyroiditis, acute Tonsillitis, acute Tonsillitis, chronic Urethra, infectious or noninfectious urethritis Urinary system, disorder NOS Uterus, inflammatory or infectious disorder Vagina or vulva, inflammatory or infectious disorder NOS Vagina, vaginitis, acute Vagina, vaginitis, chronic

Which date to use for infections in Acquired Diagnosis / Complication

	For acquired infections ie. cystitis with a positive culture, now that dates are to accompany acquired diagnoses...which date is to be entered, the date culture was sent, the date the positive result was reported, or the date abx was ordered?

tangential questions

untreatd positive urine cultures

might be better off in Urine tests, NOS, abnormal or Colonized with organism (not infected) depending how it should be coded.

	In instances of positive urine cultures that are not tx with abx, what is to be coded? Ie. colonization code combined with abnormal test result?

time restrictions around calling things iatrogenic

	Are all acquired treated UTI's (post 48 hours from admission) to be coded with an iatrogenic code? Is Iatrogenic, infection, urinary catheter coded if patient has one? The answer to this should probably go to Iatrogenic, infection, urinary catheter. The answer to this likely applies to some or all codes in Category:Iatrogenic.

Coding Antibiotic Resistance

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

Lab confirmation of results

See Pathogens#Culture reports

Cross Checks

See

Check Infection requiring pathogen must have pathogen combined code
Check Infection with implied pathogen must not have a pathogen combined code
Check Pathogens must have Infection requiring pathogen or Potential Infection
- do we want to go further, e.g. "viral infections must have virus pathogens"?
Check Antibiotic resistance must have pathogen or Infection with implied pathogen

If we end up with specific pages or sub-headings we should update Template:ICD10 Guideline Infection to link specifically.
