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.
  • Aplasia and hypoplasia of cementum
  • Dilaceration of tooth
  • Enamel hypoplasia (neonatal) (postnatal) (prenatal)
  • Regional odontodysplasia
  • Turner's tooth

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.
  • Hutchinson's teeth and mulberry molars in congenital syphilis A50.5

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).

Patient Education


Tooth Disorders

What are teeth?

Your teeth are made of a hard, bonelike material. There are four parts:

  • Enamel, your tooth's hard surface
  • Dentin, the hard yellow part under the enamel
  • Cementum, the hard tissue that covers the root and keeps your teeth in place
  • Pulp, the soft connective tissue in the center of your tooth. It contains nerves and blood vessels.

You need your teeth for many activities that you may take for granted. These include eating, speaking and even smiling.

What are tooth disorders?

There are many different problems that can affect your teeth, including:

  • Tooth decay - damage to a tooth's surface, which can lead to cavities
  • Abscess - a pocket of pus, caused by a tooth infection
  • Impacted tooth - a tooth did not erupt (break through the gum) when it should have. It is usually wisdom teeth that are impacted, but it can sometimes happen to other teeth.
  • Misaligned teeth (malocclusion)
  • Tooth injuries such as broken or chipped teeth

What causes tooth disorders?

The causes of tooth disorders varies, depending on the problem. Sometimes the cause is not taking good care of your teeth. In other cases, you may have been born with the problem or the cause is an accident.

What are the symptoms of tooth disorders?

The symptoms can vary, depending on the problem. Some of the more common symptoms include:

  • Abnormal color or shape of the tooth
  • Tooth pain
  • Worn-down teeth

How are tooth disorders diagnosed?

Your dentist will ask about your symptoms, look at your teeth, and probe them with dental instruments. In some cases, you may need dental x-rays.

What are the treatments for tooth disorders?

The treatment will depend on the problem. Some common treatments are:

  • Fillings for cavities
  • Root canals for cavities or infections that affect the pulp (inside of the tooth)
  • Extractions (pulling teeth) for teeth that are impacted and causing problems or are too damaged to be fixed. You may also have a tooth or teeth pulled because of overcrowding in your mouth.

Can tooth disorders be prevented?

The main thing that you can do to prevent tooth disorders is to take good care of your teeth:

  • Brush your teeth twice a day with a fluoride toothpaste
  • Clean between your teeth every day with floss or another type of between-the-teeth cleaner
  • Limit sugary snacks and drinks
  • Don't smoke or chew tobacco
  • See your dentist or oral health professional regularly

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.
