ICD-10 Code K08.56 – Poor Aesthetic of Existing Restoration of Tooth (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.56 – Poor aesthetic of existing restoration of tooth
What it is
K08.56 identifies a dental restoration that is present but does not look acceptable. Use it when the main issue is appearance, not fracture, decay, or loss of function.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the restoration may have visible mismatch in color, contour, shape, or surface finish compared with adjacent teeth.
When to use this code
Use this code when the dentist documents that an existing filling, crown, veneer, or similar restoration has poor esthetic appearance. It fits cases where the restoration remains in place but is judged cosmetically unsatisfactory. If the record describes another problem, such as damage or recurrent caries, code the documented condition instead.
Do not use for
Do not use K08.56 for broken, loose, or missing restorations, or for decay around a restoration. Check documentation if the concern is function, pain, or structural failure rather than appearance.
Coding tip
Assign K08.56 only when the chart clearly states poor aesthetics as the reason for the encounter.
