Moderate atrophy of the maxilla

This code signifies a noticeable reduction in the size and density of the upper jawbone (maxilla) due to bone loss, which is moderate in severity. This atrophy can affect the alveolar ridge, impacting the stability of prosthetics or the feasibility of dental implants. It often results from tooth loss and lack of functional stimulation over time.

Assign this code when documentation explicitly states "moderate atrophy of the maxilla" or describes bone loss in the maxilla that is clinically assessed as moderate. This is typically identified through radiographic imaging (e.g., panoramic X-ray, CBCT) and clinical examination. Use this code to describe the underlying condition impacting dental treatment planning, such as for implant placement or denture fabrication.

• Ensure the documentation specifies "moderate" atrophy; avoid using this code for mild or severe cases.
• Distinguish from mandibular atrophy (K08.26-K08.29) and generalized atrophy of the alveolar ridge (K08.20).
• Consider sequencing this code as a secondary diagnosis when the primary reason for the encounter is a related dental procedure (e.g., implant consultation, denture fitting).
