Osteitis condensans, left lower leg

This code represents osteitis condensans affecting the left lower leg. This is a benign, non-inflammatory condition characterized by increased bone density, typically seen as a localized area of sclerosis on imaging, without evidence of infection or tumor. It often results from chronic stress or degenerative changes.

Use this code when documentation specifies osteitis condensans located in the left tibia or fibula. Supporting documentation should include imaging reports (e.g., X-ray, MRI) confirming localized bone sclerosis in the left lower leg, along with a physician's diagnostic statement. This code is appropriate when the condition is asymptomatic or causing localized pain.

• Ensure laterality is clearly documented as "left" for the lower leg.
• Do not confuse with osteomyelitis (infection) or other sclerotic bone lesions; osteitis condensans is non-infectious and non-neoplastic.
• If the specific bone (tibia or fibula) is documented, consider if a more specific code within the M85.3- category is available, though M85.362 is specific to the lower leg.
