ICD-10 Code K08.2 – Atrophy of edentulous alveolar ridge (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.2 – Atrophy of edentulous alveolar ridge
What it is
K08.2 identifies loss of alveolar bone height and width in a jaw segment that no longer has teeth. In plain terms, it describes shrinkage of the tooth-bearing ridge after edentulism.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a flattened or narrowed ridge, reduced support for dentures, and difficulty with prosthetic fit after tooth loss.
When to use this code
Use K08.2 when the record clearly documents atrophy of an edentulous alveolar ridge, usually in a patient without teeth in that area. You may also use it when the provider notes ridge resorption or loss of ridge volume as the diagnosis. Check documentation if the note only mentions missing teeth without ridge atrophy.
Do not use for
Do not use this code for simple tooth loss, periodontal disease, or other jaw disorders without documented ridge atrophy. If the chart does not confirm an edentulous ridge problem, check documentation.
Coding tip
Code K08.2 only when the provider links the finding to an edentulous ridge, not merely to dentures or prior extractions.
