ICD-10 Code K08.24 – Minimal atrophy of maxilla (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.24 – Minimal atrophy of maxilla
What it is
K08.24 identifies minimal loss of maxillary bone volume, usually in the upper jaw. It is used when documentation states mild atrophy of the maxilla and the finding is clinically relevant.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record may describe slight ridge resorption, reduced bone height, or mild anatomical flattening of the maxilla on examination or imaging.
When to use this code
Use this code when the provider documents minimal atrophy of the maxilla as the diagnosed condition. It may appear in dental, oral surgery, or implant planning notes when the degree of bone loss is specifically described. If the note only says “atrophy” without severity, check documentation.
Do not use for
Do not use this code for mandibular atrophy or generalized jaw bone loss. Avoid it when the chart does not specify the maxilla or when the severity is not documented; check documentation.
Coding tip
Code the site and severity exactly as documented, and do not assume minimal atrophy from imaging alone.
