ICD-10 Code K08.432 – Partial loss of teeth due to caries, class II (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.432 – Partial loss of teeth due to caries, class II
What it is
This code identifies partial loss of teeth caused by dental caries, with the loss pattern classified as class II. Use it when documentation specifically links the missing teeth to decay and names the class.
Clinical signs
Clinical features vary; refer to documentation. You may see missing teeth, retained tooth roots, or a history of caries-related extraction, but the key point is that the record supports class II partial tooth loss.
When to use this code
Use this code when the provider documents partial loss of teeth due to caries and specifies class II. It fits dental records, problem lists, or claims where the cause is decay rather than trauma, periodontal disease, or congenital absence.
If the chart only says “missing teeth” or “tooth loss” without a cause, check documentation before coding. Code only when the caries connection and the class designation are clear.
Do not use for
Do not use this code for tooth loss from injury, periodontal disease, or extraction without documented caries. If the cause or class is unclear, check documentation.
Coding tip
Match the code to both the cause and the class; if either is missing, query the record before assigning K08.432.
