Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Acute rhinitis
  • Coryza (acute)
  • Infective nasopharyngitis NOS
  • Infective rhinitis
  • Nasal catarrh, acute
  • Nasopharyngitis NOS

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert J00 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Acute nasopharyngitis

ICD-9-CM: 460

This is a direct match with no additional mapping qualifiers. The absence of a flag generally means the mapping is considered exact or precise. In other words, the ICD-10 code maps cleanly to the ICD-9 code without qualification, approximation, or needing multiple codes.

Patient Education


Common Cold

What is the common cold?

The common cold is a mild infection of your upper respiratory tract (which includes your nose and throat). Colds are probably the most common illness. Adults have an average of 2-3 colds per year, and children have even more. Colds are more common in the winter and spring, but you can get them at any time.

What causes the common cold?

More than 200 different viruses can cause a cold, but rhinoviruses are the most common type. The viruses that cause colds are very contagious. They can spread from person to person through the air and close personal contact. You can also get infected when you touch something that has the virus on it and then touch your eyes, mouth, or nose. For example, you could get a cold after you shake hands with someone who has a cold or touch a doorknob that has the germs on it, and then touch your face.

What are the symptoms of the common cold?

The symptoms of a common cold usually include:

  • Sneezing
  • Stuffy nose (congestion)
  • Runny nose
  • Sore throat
  • Coughing
  • Headache

The symptoms usually start a few days after you become infected with the virus. Some symptoms can last for 10-14 days.

What are the treatments for the common cold?

There is no cure for the common cold. But there are treatments that can make you feel better while you wait for the cold to go away on its own:

  • Getting lots of rest.
  • Drinking plenty of fluids.
  • Using a clean humidifier or cool mist vaporizer.
  • Gargling with warm salt water.
  • Using saline nose drops or sprays.
  • Taking over-the-counter pain or cold and cough medicines. But you need to be careful with certain medicines:
    • Children and teens should not take aspirin.
    • Some cold and cough medicines contain ingredients that are not recommended for children. Talk with your child's health care provider before giving your child any cold and cough medicines.
    • Some cold and cough medicines contain pain relievers. If you also take a separate pain reliever with these medicines, you could be getting a dangerous amount of the pain reliever. Read the labels on the medicines and follow the instructions carefully. If you have questions, ask your provider or a pharmacist.

Antibiotics will not help with a cold. Antibiotics help with bacterial infections, not with viral infections such as colds.

Most people who have a cold will feel better after a week or two. However, some people who get a cold may develop other illnesses, such as bronchitis or pneumonia. This is more common in people with weakened immune systems, asthma, or other respiratory conditions. Contact your provider if you or your child have symptoms that concern you, such as:

  • Trouble breathing or fast breathing
  • Dehydration
  • Fever that lasts longer than 4 days
  • Symptoms that last more than 10 days without improvement
  • Symptoms, such as fever or cough, that improve but then return or worsen
  • Worsening of chronic medical conditions

Can the common cold be prevented?

There is no vaccine to protect against the common cold. But you may be able to reduce your risk of getting or spreading a cold by:

  • Washing your hands often with soap and water for at least 20 seconds.
  • Avoiding touching your face, nose, or mouth with unwashed hands.
  • Avoiding close contact, such as kissing, shaking hands, and sharing cups and eating utensils, with others if you are sick or they are sick.
  • Cleaning and disinfecting surfaces that you frequently touch.
  • Covering coughs and sneezes with a tissue. Then throw away the tissue and wash your hands.
  • Staying home when sick.

Footnotes

[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.
