Code Description

ICD-10 M61.312 is a billable code used to indicate a diagnosis of calcification and ossification of muscles associated with burns, left shoulder.

Key Diagnostic Point:

Calcification and ossification of muscles associated with burns is a condition that arises when muscle tissue undergoes pathological changes due to thermal injury. In the case of burns, the affected muscle may experience necrosis and subsequent calcification or ossification as part of the healing process. This condition is particularly relevant in the left shoulder region, where the muscles may become stiff and lose functionality due to the deposition of calcium salts or bone-like tissue. Patients may present with muscle weakness, limited range of motion, and pain in the affected area. The underlying pathophysiology involves inflammation and repair mechanisms that can lead to abnormal mineralization of muscle tissue. Clinicians must assess the extent of muscle involvement and the impact on neuromuscular function, as this can significantly affect rehabilitation outcomes. Proper documentation of the burn severity, location, and associated muscle involvement is crucial for accurate coding and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of burn classifications and their effects on muscle tissue.
  • Involves knowledge of muscle pathology related to calcification and ossification.
  • Documentation must specify the location and extent of muscle involvement.
  • Differentiating from other muscle disorders can be challenging.

Audit Risk Factors

  • Inadequate documentation of burn severity and muscle involvement.
  • Failure to specify the left shoulder as the affected site.
  • Misclassification of the condition as a primary muscle disorder.
  • Lack of supporting clinical evidence for calcification or ossification.
