ICD-10 Code K08.433 – Partial loss of teeth due to caries, class III (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.433 – Partial loss of teeth due to caries, class III
What it is
K08.433 identifies partial tooth loss caused by dental caries, with class III severity. Use it when documentation specifies this level of tooth loss due to decay, not trauma or periodontal disease.
Clinical signs
Typical findings include missing teeth attributable to caries and documented partial loss in the class III category. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states partial loss of teeth from caries and identifies class III. It may appear in dental, oral surgery, or general medical notes describing tooth loss due to decay. If the cause or class is not documented, check documentation.
Do not use for
Do not use it for tooth loss from trauma, periodontal disease, or congenital absence. Do not assign it when caries is present but partial loss and class III are not documented.
Coding tip
Confirm both the cause and the class level in the chart before coding K08.433.
