Infectious and parasitic diseases are reported from Chapter
1 of ICD-10-CM
Infectious diseases occur when a pathogen invades the
body and causes disease.
 Bacteria
are one-celled organisms that are
named according to their shapes and
arrangements.
o Bacterial infections include:
o Salmonella
o E. coli
o Streptococci
o Mycobacterium tuberculosis
Fungi – Microscopic plant life that lacks
chlorophyll and must have a source of matter
for nutrition.
 Common fungal infections:
o Yeast infections
o Molds
 Organisms
that feed on other organisms to
nourish themselves.
 Common parasites include:
o Protozoa
o Helminths
o Arthropods
 Viruses
are the smallest of infectious
pathogens.
 Common viral infections include:
o Herpes zoster- shingles
o Varicella- chickenpox
o HIV- AIDS
o Herpes simplex- genital herpes
o RNA virus- German measles
 This
range of codes includes cholera,
shingellosis, and other bacterial infections.
 Food poisoning and viral intestinal infections
are also found here.
 Common symptoms include: nausea,
vomiting, anorexia, abdominal pain, fever,
muscular aches, and malaise.
 Tuberculosis
is caused by Mycobacterium
tuberculosis.
 Reference the instructional notations found
at the beginning of the section.
 Symptoms include: fatigue, weakness, loss
of appetite and weight, coughing,
hemoptysis, night sweats, and increased
temperature later in the day and evening.

 Single,
combination, and dual code
assignment are used for coding in this
chapter of ICD-10-CM.
 An underlying condition/infection is
sequenced first, followed by the
manifestation code.
 Coders should be cautious when reporting
HIV cases and reference documentation
prior to code assignment.
 Reference
the Official ICD-10-CM Coding
Guidelines for chapter-specific guidelines on:
o HIV infections
o Infectious agents as the cause of disease
classified to other chapters
o Infections resistant to antibiotics
o Sepsis, severe sepsis, and septic shock
