K08.403 Partial loss of teeth, unspecified cause, class III

ICD10CM code

#### Name of the Condition
- Partial Loss of Teeth, Unspecified Cause, Class III (ICD-10-CM Code: K08.403)

#### Summary
Partial loss of teeth refers to the absence of one or more teeth, but not all teeth are missing. The term "unspecified cause" indicates that the reason for tooth loss is not clearly identified in the patient's records, and Class III often refers to the extent of tooth loss which may require prosthetic or other dental interventions.

#### Causes
While the exact cause of tooth loss in this category is unspecified, common contributing factors can include trauma, untreated dental conditions, genetic predispositions, or systemic diseases that affect oral health.

#### Risk Factors
- Aging, as older adults are more prone to tooth loss.
- Poor oral hygiene leading to dental decay or gum disease.
- Smoking or tobacco use.
- Diabetes or other systemic health conditions.
- Insufficient dental care or lack of regular dental check-ups.

#### Symptoms
- Presence of gaps in the dental arch.
- Difficulty in chewing or speaking due to missing teeth.
- Shifting of remaining teeth.

#### Diagnosis
- Physical examination by a dentist.
- Dental X-rays to assess the degree of tooth loss and the condition of the surrounding teeth and bone structure.

#### Treatment Options
- **Dental Prosthetics (e.g., partial dentures):** Replaces missing teeth and improves function.
- **Dental Implants:** Provides a long-term replacement for missing teeth.
- **Bridges:** Fills gaps between teeth using adjacent teeth for support.

#### Prognosis and Follow-Up
With proper treatment, individuals can maintain oral function and appearance. Regular follow-up appointments are crucial to ensure that prosthetic devices are functioning well and to monitor oral health.

#### Complications
- Further tooth loss if untreated.
- Misalignment of remaining teeth leading to bite issues.
- Increased risk of gum disease or jawbone loss.

#### Lifestyle & Prevention
- Maintain good oral hygiene by brushing and flossing daily.
- Regular visits to the dentist for cleanings and check-ups.
- Reduce acid and sugar intake in diet to protect remaining teeth.

#### When to Seek Professional Help
- Persistent pain or discomfort in the mouth.
- Noticeable changes in tooth alignment or increased tooth mobility.
- Difficulty in eating or speaking that affects daily life.

- American Dental Association (ADA) [website](https://www.ada.org) for oral health information.
- National Institute of Dental and Craniofacial Research (NIDCR) [website](https://www.nidcr.nih.gov) for research and education.

#### Tips for Medical Coders
- Ensure that the extent and cause of tooth loss are well-documented in patient records.
- Avoid assuming the cause of loss; code it as 'unspecified' unless clearly stated.
- Double-check that Class III designation appropriately reflects the patient's dental status.
