Minimal atrophy of maxilla

This code describes a slight reduction in the size or wasting away of the upper jaw bone (maxilla). It indicates a minor degree of bone loss that may be observed radiographically or clinically, often without significant functional impairment.

Use this code when documentation specifies "minimal atrophy of the maxilla" or similar mild bone resorption in the upper jaw. This is often noted during dental examinations, pre-prosthetic evaluations, or imaging studies (e.g., panoramic X-rays, CBCT scans) where the bone loss is not extensive.

• Ensure documentation explicitly states "minimal" or "slight" atrophy; avoid using for moderate or severe cases.
• Do not confuse with atrophy of the mandible (lower jaw), which has separate codes.
• Consider if an underlying cause for the atrophy (e.g., edentulism) is documented and should be coded as a primary or secondary diagnosis.
