Skeletal fluorosis, multiple sites

This code signifies a chronic bone disease resulting from excessive fluoride intake, affecting multiple areas of the skeleton. It leads to increased bone density, calcification of ligaments, and potential joint pain and stiffness due to abnormal bone formation.

Use this code for patients diagnosed with skeletal fluorosis where the condition is documented as affecting more than one skeletal site. Documentation should clearly indicate a history of prolonged high fluoride exposure and clinical findings consistent with widespread skeletal involvement.

• Ensure documentation specifies "multiple sites" to differentiate from localized fluorosis.
• Consider sequencing this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis when it contributes to the patient's overall condition.
• Verify the fluoride exposure source (e.g., contaminated water, industrial exposure) if available in the medical record, though not required for code assignment.
