ICD-10 Code K08.539 – Fractured dental restorative material, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.539 – Fractured dental restorative material, unspecified
What it is
This code identifies a break, crack, or failure of a dental restorative material when the exact type is not specified. Use it for damaged fillings, crowns, or other restorations if documentation does not name the material.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record notes a visible fracture, chipped restoration, rough edges, or patient-reported pain, sensitivity, or difficulty chewing.
When to use this code
Use K08.539 when the provider documents a fractured dental restoration but does not identify whether it is amalgam, composite, ceramic, or another material. It also fits when the note confirms restoration failure without further detail. Code only what is documented.
Do not use for
Do not use this code for fracture of the tooth itself, loss of a restoration without fracture, or complications that are documented more specifically. Check documentation if the material type or underlying problem is named.
Coding tip
If the record names the restoration material, choose the more specific code instead of this unspecified option.
