Code Classification

  • Certain infectious and parasitic diseases
    (A00–B99)
    • Other infectious diseases
      (B99)
      • Other and unspecified infectious diseases
        (B99)

B99.9 is a billable diagnosis code used to specify a medical diagnosis of unspecified infectious disease. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like B99.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Persistent Infection

    infection which lasts for a long period with continuous display of clinical features. persistent infection arises due to inability of host cells to clear primary infections completely. when persistent infections are cleared so that infection symptoms are under control they are often referred to as chronic infections. latent infections are infections in which manifestation of clinical symptoms appear later.
  • Cross Infection

    any infection which a patient contracts in a health-care institution.
  • Seroma

    tumor-like sterile accumulation of serum in a tissue, organ, or cavity. it results from a tissue insult and is the product of tissue inflammation. it most commonly occurs following mastectomy.
  • Latent Infection

    delayed infection of the host by a dormant or inactive pathogen.
  • Mastectomy

    surgical procedure to remove one or both breasts.
  • Umbilical Granuloma

    excessive granulation tissue at the base of the umbilicus after separation.
  • Early Prosthetic Valve Endocarditis

    prosthetic valve endocarditis that occurs days to weeks after surgery.
  • Late Prosthetic Valve Endocarditis

    prosthetic valve endocarditis that occurs several months to years following valve replacement.
  • Prosthetic Valve Endocarditis

    endocarditis occurring on parts of a valve prosthesis or a reconstructed heart valve; it can be classified into early and late prosthetic valve endocarditis.
  • Neonatal Dacryocystitis

    inflammation of the lacrimal sac in a newborn due to blocked drainage of tears or infection.
  • Omphalitis

    inflammation of the umbilical cord stump in newborns.
  • Acute Pyelonephritis

    sudden onset pyelonephritis.
  • Grade 1 Seroma, CTCAE|Grade 1 Seroma|Grade 1 Seroma

    asymptomatic; clinical or diagnostic observations only; intervention not indicated
  • Grade 2 Seroma, CTCAE|Grade 2 Seroma|Grade 2 Seroma

    symptomatic; simple aspiration indicated
  • Grade 3 Seroma, CTCAE|Grade 3 Seroma|Grade 3 Seroma

    symptomatic, elective invasive intervention indicated
  • Seroma

    a collection of serum in the body.
  • Seroma, CTCAE|Seroma|Seroma|Seroma

    a finding of tumor-like collection of serum in the tissues.

Infectious Diseases

What are infectious diseases?

Germs, or microbes, are found everywhere - in the air, soil, and water. There are also germs on your skin and in your body. Many of them are harmless, and some can even be helpful. But some of them can make you sick. Infectious diseases are diseases that are caused by germs.

What are the different types of germs that cause infectious diseases?

There are four main types of germs:

  • Bacteria are one-celled germs that multiply quickly. They may give off toxins, which are harmful chemicals that can make you sick. Strep throat and urinary tract infections are common bacterial infections.
  • Viruses are tiny capsules that contain genetic material. They invade your cells so that they can multiply. This can kill, damage, or change the cells and make you sick. Viral infections include HIV and the common cold.
  • Fungi are primitive plant-like organisms such as mushrooms, mold, mildew, and yeasts. Athlete's foot and yeast infections are common fungal infections.
  • Parasites are animals or plants that survive by living on or in other living things. Malaria and head lice are infections that are caused by parasites.

How can you get infectious diseases?

There are many different ways that you can get an infectious disease:

  • Through direct contact with a person who is sick. This includes kissing, touching, sneezing, coughing, and sexual contact. Pregnant people can also pass some germs along to their babies.
  • Through indirect contact, when you touch something that has germs on it. For example, you could get germs if someone who is sick touched a door handle, and then you touch it.
  • Through insect or animal bites.
  • Through contaminated food, water, soil, or plants.

What are the symptoms of infectious diseases?

Infectious diseases can cause many different symptoms. Some are so mild that you may not even notice any symptoms, while others can be life-threatening.

What are the treatments for infectious diseases?

There are treatments for some infectious diseases, such as antibiotic, antiviral, antifungal and anti-parasitic medicines. But for other infections, such as some caused by viruses, you can only treat your symptoms.

Can infectious diseases be prevented?

You can take steps to prevent many infectious diseases:

  • Get vaccinated
  • Wash your hands often
  • Pay attention to food safety
  • Avoid contact with wild animals
  • Practice safe sex (use a condom every time you have anal, vaginal, or oral sex)
  • Don't share items such as toothbrushes, combs, and straws

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
