ICD-10: M85.161

Skeletal fluorosis is a bone disease caused by excessive accumulation of fluoride in the bones, typically due to prolonged exposure to high levels of fluoride, often from drinking water, dental products, or industrial exposure. The ICD-10 code M85.161 specifically refers to skeletal fluorosis localized in the right lower leg.

Clinical Description of Skeletal Fluorosis

Etiology

Skeletal fluorosis occurs when fluoride levels in the body exceed safe thresholds, leading to changes in bone structure and density. This condition is primarily associated with:

• Environmental Exposure: High fluoride levels in drinking water, particularly in certain geographic areas.
• Occupational Exposure: Workers in industries such as aluminum production, phosphate fertilizer manufacturing, and glass etching may be at risk.
