ICD-10 Code K08.52 – Unrepairable overhanging of dental restorative materials (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.52 – Unrepairable overhanging of dental restorative materials
What it is
K08.52 identifies a dental restoration with excess material extending beyond the tooth contour that cannot be corrected. Use it when the overhang is documented as unrepairable rather than simply present.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart notes an overhanging restoration margin that is not amenable to adjustment or repair.
When to use this code
Use this code when the dentist documents an overhanging restorative material and states it is unrepairable. It may appear in records describing a defective filling, crown margin, or similar restoration that requires replacement or other management. Check documentation for the exact restorative site and wording.
Do not use for
Do not use this code for a minor overhang that can be smoothed, adjusted, or repaired. Also avoid it when the record does not clearly state that the overhang is unrepairable.
Coding tip
If the note only says “overhang,” query for whether it is unrepairable before assigning K08.52.
