ICD-10 Code K08.531 – Fractured dental restorative material with loss of material (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.531 – Fractured dental restorative material with loss of material
What it is
K08.531 identifies a fractured dental restorative material when part of the restoration is missing. Use it for damage to fillings, crowns, or similar restorations when the record states loss of material.
Clinical signs
Documentation may note a broken, chipped, or missing portion of restorative material, often with rough edges or an incomplete restoration. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents fracture of a dental restoration with actual loss of material, such as a missing piece of a filling or crown. It fits cases where the restoration is damaged, not merely worn or discolored. Check documentation for the specific tooth and restoration type if recorded.
Do not use for
Do not use it for intact restorations, cosmetic concerns, or general tooth pain without documented fracture. If the chart does not confirm loss of restorative material, check documentation.
Coding tip
Look for the words “fractured” and “loss of material” together before assigning K08.531.
