K04.4 Acute apical periodontitis of pulpal origin

ICD10CM code

#### Name of the Condition
- **Acute Apical Periodontitis of Pulpal Origin**
- Also known as acute apical periodontitis.

#### Summary
Acute apical periodontitis of pulpal origin is a dental condition characterized by inflammation at the apex of a tooth's root. This condition is usually a result of infection spreading from the dental pulp into the surrounding apical tissues, often causing noticeable pain.

#### Causes
- Bacterial infection stemming from untreated dental caries or trauma to the tooth.
- Pulp necrosis or pulpitis leading to infection spreading to the root apex.

#### Risk Factors
- Poor oral hygiene increasing susceptibility to dental caries.
- History of significant dental trauma or extensive dental procedures.
- Previous untreated cavities or dental fractures.

#### Symptoms
- Severe sensitivity or pain localized to the affected tooth.
- Swelling or tenderness of the gums near the root of the tooth.
- Possible formation of a dental abscess if the infection progresses.

#### Diagnosis
- Clinical examination to assess symptoms and tenderness.
- Dental imaging, such as X-rays, to evaluate the extent of the condition and check for bone loss or abscesses.

#### Treatment Options
- Root canal therapy to remove the infected pulp and clean the tooth's interior.
- Antibiotics if there is a significant spread of infection or abscess formation.
- Analgesics for pain management.

#### Prognosis and Follow-Up
- Good prognosis with prompt and appropriate dental treatment.
- Regular dental check-ups are crucial to ensure healing and prevent recurrence.

#### Complications
- If untreated, the infection can lead to abscess formation and spread to surrounding tissues.
- Possible loss of the affected tooth if the infection severely damages the surrounding structures.

#### Lifestyle & Prevention
- Maintain rigorous oral hygiene practices, including regular brushing and flossing.
- Monitor for early signs of dental decay or pulp exposure and seek treatment promptly.
- Regular dental check-ups for early detection and management of dental issues.

#### When to Seek Professional Help
- Sudden onset of severe tooth pain or persistent discomfort.
- Noticeable swelling or abscess formation around the affected tooth.
- Prolonged sensitivity to hot or cold stimuli that doesn't resolve.

#### Additional Resources
- [American Dental Association](https://www.ada.org) for information on dental health and conditions.
- Dental care forums and support groups for patient experiences and advice.

#### Tips for Medical Coders
- Use the specific ICD code **K04.4** for acute apical periodontitis of pulpal origin.
- Ensure the condition is correctly documented as of pulpal origin to avoid confusion with other types of periodontitis.
