ICD-10 Code K08.25 – Moderate atrophy of the maxilla (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.25 – Moderate atrophy of the maxilla
What it is
K08.25 identifies moderate loss of maxillary bone volume, usually from resorption of the upper jaw. You use it when the record documents moderate atrophy of the maxilla, not just general tooth loss.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the maxilla appears reduced in height or width, with diminished ridge support that may affect denture fit or oral anatomy.
When to use this code
Use this code when the clinician documents moderate atrophy of the maxilla as the diagnosis. It is appropriate in dental, oral surgery, or maxillofacial records describing bony resorption of the upper jaw. If severity is not stated, check documentation before assigning K08.25.
Do not use for
Do not use it for unspecified jaw atrophy, mandibular atrophy, or simple edentulism without documented maxillary bone loss. If the note only says “bone loss” or “poor denture retention,” check documentation.
Coding tip
Assign K08.25 only when “moderate” maxillary atrophy is clearly documented; otherwise, query for the exact site and severity.
