2021 ICD-10-CM Code J03.00

Acute streptococcal tonsillitis, unspecified

Version 2021

Valid for Submission

J03.00 is a billable diagnosis code used to specify a medical diagnosis of acute streptococcal tonsillitis, unspecified. The code J03.00 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code J03.00 might also be used to specify conditions or terms like acute bacterial pharyngitis, acute bacterial tonsillitis, acute tonsillitis caused by streptococcus, pneumococcal pharyngitis, pneumococcal tonsillitis , streptococcal sore throat, etc.

Unspecified diagnosis codes like J03.00 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.

Information for Patients


Streptococcal Infections

Also called: Strep

Strep is short for Streptococcus, a type of bacteria. There are several types. Two of them cause most of the strep infections in people: group A and group B.

Group A strep causes

Group B strep can cause blood infections, pneumonia and meningitis in newborns. A screening test during pregnancy can tell if you have it. If you do, I.V. antibiotics during labor can save your baby's life. Adults can also get group B strep infections, especially if they are elderly or already have health problems. Strep B can cause urinary tract infections, blood infections, skin infections and pneumonia in adults.

Antibiotics are used to treat strep infections.

Tonsillitis

Also called: Tonsil Inflammation

What are tonsils?

Tonsils are lumps of tissue at the back of the throat. There are two of them, one on each side. Along with the adenoids, tonsils are part of the lymphatic system. The lymphatic system clears away infection and keeps body fluids in balance. Tonsils and adenoids work by trapping the germs coming in through the mouth and nose.

What is tonsillitis?

Tonsillitis is an inflammation (swelling) of the tonsils. Sometimes along with tonsillitis, the adenoids are also swollen.

What causes tonsillitis?

The cause of tonsillitis is usually a viral infection. Bacterial infections such as strep throat can also cause tonsillitis.

Who is at risk for tonsillitis?

Tonsillitis is most common in children over age two. Almost every child in the United States gets it at least once. Tonsillitis caused by bacteria is more common in kids ages 5-15. Tonsillitis caused by a virus is more common in younger children.

Adults can get tonsillitis, but it is not very common.

Is tonsillitis contagious?

Although tonsillitis is not contagious, the viruses and bacteria that cause it are contagious. Frequent handwashing can help prevent spreading or catching the infections.

What are the symptoms of tonsillitis?

The symptoms of tonsillitis include

When should I get medical help for my child?

You should call your health care provider if your child

You should get emergency care right away if your child

How is tonsillitis diagnosed?

To diagnose tonsillitis, your child's health care provider will first ask you about your child's symptoms and medical history. The provider will look at your child's throat and neck, checking for things such as redness or white spots on the tonsils and swollen lymph nodes.

Your child will probably also have one or more tests to check for strep throat, since it can cause tonsillitis and it requires treatment. It could be a rapid strep test, a throat culture, or both. For both tests, the provider uses a cotton swab to collect a sample of fluids from your child's tonsils and the back of the throat. With the rapid strep test, testing is done in the office, and you get the results within minutes. The throat culture is done in a lab, and it usually takes a few days to get the results. The throat culture is a more reliable test. So sometimes if the rapid strep test is negative (meaning that it does not show any strep bacteria), the provider will also do a throat culture just to make sure that your child does not have strep.

What are the treatments for tonsillitis?

Treatment for tonsillitis depends on the cause. If the cause is a virus, there is no medicine to treat it. If the cause is a bacterial infection, such as strep throat, your child will need to take antibiotics. It is important for your child to finish the antibiotics even if he or she feels better. If treatment stops too soon, some bacteria may survive and re-infect your child.

No matter what is causing the tonsillitis, there are some things you can do to help your child feel better. Make sure that your child

In some cases, your child may need a tonsillectomy.

What is a tonsillectomy and why might my child need one?

A tonsillectomy is surgery to remove the tonsils. Your child might need it if he or she

Your child usually gets the surgery and goes home later that day. Very young children and people who have complications may need to stay in the hospital overnight. It can take a week or two before your child completely recovers from the surgery.
