ICD-10 Code K08.22 – Moderate atrophy of the mandible (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K08.22 – Moderate atrophy of the mandible
What it is
K08.22 identifies a moderate loss of mandibular bone volume. You use it when the chart documents a reduced, resorbed mandible that is not described as severe.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe a narrowed, resorbed mandibular ridge, reduced bone height, or difficulty supporting dentures because of bone loss.
When to use this code
Use this code when the clinician specifically documents moderate atrophy of the mandible, often in dental or oral surgery notes. It may also appear in pre-procedure assessments when mandibular bone loss affects prosthetic planning or implant candidacy.
Do not use for
Do not use it for mild or severe mandibular atrophy unless the record says moderate. Check documentation if the note only mentions general jaw bone loss without grading.
Coding tip
Code the documented severity exactly as stated; if the degree is unclear, query the provider before assigning K08.22.
