Osteitis condensans, unspecified thigh

This code describes a benign, non-inflammatory bone condition characterized by increased bone density, specifically affecting an unspecified area of the thigh. It typically presents as a localized area of sclerosis without evidence of infection or malignancy.

Assign this code when documentation indicates osteitis condensans affecting the thigh, and the specific laterality (left or right) or precise anatomical site within the thigh is not specified. This diagnosis is often made incidentally on imaging studies.

• Ensure the documentation explicitly states "thigh" and that no laterality is specified.
• Differentiate from other bone sclerosis conditions, such as osteomyelitis or bone tumors, which would require different codes.
• If laterality (left or right thigh) is documented, a more specific code should be used.
