Code Description

ICD-10 M61.311 is a billable code used to indicate a diagnosis of calcification and ossification of muscles associated with burns, right shoulder.

Key Diagnostic Point:

Calcification and ossification of muscles associated with burns is a condition that occurs when muscle tissue undergoes abnormal mineralization following thermal injury. In the case of the right shoulder, this can lead to significant functional impairment and pain. The process typically begins with inflammation and necrosis of muscle fibers due to the burn injury, followed by a healing phase where calcium deposits form in the affected muscles. This condition can result in myositis, characterized by muscle inflammation, and may lead to muscle weakness and reduced range of motion. Patients may experience symptoms such as localized pain, swelling, and stiffness in the shoulder area. The presence of calcification can complicate rehabilitation efforts, as it may limit the effectiveness of physical therapy and increase the risk of further injury. Accurate diagnosis often requires imaging studies, such as X-rays or MRI, to assess the extent of calcification and to differentiate it from other musculoskeletal conditions. Management typically involves a multidisciplinary approach, including pain management, physical therapy, and in some cases, surgical intervention to remove calcified tissue.

  • Potential for co-existing conditions affecting coding

Audit Risk Factors

  • Inadequate documentation of burn severity
  • Failure to specify the affected muscle group
  • Lack of imaging studies to support diagnosis
  • Misinterpretation of muscle weakness as a separate condition

Frequently Asked Questions

What is the primary cause of calcification in muscles associated with burns?

Calcification in muscles following burns is primarily caused by the inflammatory response and tissue damage that occurs due to the thermal injury, leading to abnormal mineralization during the healing process.
