ICD-10 Code K08.50 – Unsatisfactory restoration of tooth, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.50 – Unsatisfactory restoration of tooth, unspecified
What it is
K08.50 identifies a dental restoration that is present but not satisfactory, with no further detail about the specific problem. Use it when the record does not specify the type of restoration or the reason it is considered unsatisfactory.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note a defective, loose, worn, broken, or poorly fitting restoration, but you should code only what the provider documents.
When to use this code
Use K08.50 when the dentist or other qualified clinician documents an unsatisfactory tooth restoration and does not identify a more specific diagnosis. It is appropriate for nonspecific findings involving a filling, crown, or similar restoration when the record lacks detail. Check documentation if the cause or type is stated.
Do not use for
Do not use this code when the record gives a more specific restoration problem, such as fracture, displacement, or caries under a restoration. Also avoid it if the complaint is about a missing restoration rather than an unsatisfactory one.
Coding tip
If the note names the restoration type or defect, code the more specific documented condition instead of K08.50.
