Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Certain zoonotic bacterial diseases
      (A20-A28)
      • Anthrax
        (A22)

A22 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of anthrax. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Anthrax

Non-specific codes like A22 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for anthrax:

  • Use A22.0 for Cutaneous anthrax - BILLABLE CODE

  • Use A22.1 for Pulmonary anthrax - BILLABLE CODE

  • Use A22.2 for Gastrointestinal anthrax - BILLABLE CODE

  • Use A22.7 for Anthrax sepsis - BILLABLE CODE

  • Use A22.8 for Other forms of anthrax - BILLABLE CODE

  • Use A22.9 for Anthrax, unspecified - BILLABLE CODE

Clinical Information

  • Anthrax

    an acute infection caused by the spore-forming bacteria bacillus anthracis. it commonly affects hoofed animals such as sheep and goats. infection in humans often involves the skin (cutaneous anthrax), the lungs (inhalation anthrax), or the gastrointestinal tract. anthrax is not contagious and can be treated with antibiotics.
  • Anthrax Vaccines

    vaccines or candidate vaccines used to prevent anthrax.
  • Bacillus anthracis

    a species of bacteria that causes anthrax in humans and animals.
  • Anthrax

    an infection caused by bacillus anthracis bacteria. it may affect the lungs, gastrointestinal tract, or skin. patients with lung infection present with fever, headaches, cough, chest pain and shortness of breath. patients with gastrointestinal infection present with nausea, vomiting and bloody diarrhea. patients with skin infection develop blisters and ulcers.
  • Anthrax Toxin Receptor 1|ANTXR1|Tumor Endothelial Marker 8

    anthrax toxin receptor 1 (564 aa, ~63 kda) is encoded by the human antxr1 gene. this protein plays a role in the regulation of both cell adhesion and cellular motility.
  • ANTXR1 Gene|ANTXR1|ANTXR1|Anthrax Toxin Receptor 1 Gene

    this gene plays a role in cell-matrix adhesion.
  • ANTXR1 wt Allele|ATR|Anthrax Toxin Receptor 1 wt Allele|FLJ10601|FLJ21776|TEM8

    human antxr1 wild-type allele is located in the vicinity of 2p13.1 and is approximately 236 kb in length. this allele, which encodes anthrax toxin receptor 1 protein, is involved in the modulation of cytoskeletal rearrangement, cellular adhesion and cell migration. mutation of the gene is associated with hemangioma capillary infantile.

Patient Education


Anthrax

Anthrax is a disease caused by Bacillus anthracis, a germ that lives in soil. Many people know about it from the 2001 bioterror attacks. In the attacks, someone purposely spread anthrax through the U.S. mail. This killed five people and made 22 sick.

Anthrax is rare. It affects animals such as cattle, sheep, and goats more often than people. People can get anthrax from contact with infected animals, wool, meat, or hides. It can cause three forms of disease in people. They are:

  • Cutaneous, which affects the skin. People with cuts or open sores can get it if they touch the bacteria.
  • Inhalation, which affects the lungs. You can get this if you breathe in spores of the bacteria.
  • Gastrointestinal, which affects the digestive system. You can get it by eating infected meat.

Antibiotics often cure anthrax if it is diagnosed early. But many people don't know they have anthrax until it is too late to treat. A vaccine to prevent anthrax is available for people in the military and others at high risk.
