Code Description

ICD-10 M61.232 is a billable code used to indicate a diagnosis of paralytic calcification and ossification of muscle, left forearm.

Key Diagnostic Point:

Paralytic calcification and ossification of muscle, specifically in the left forearm, is a condition characterized by the abnormal deposition of calcium salts in muscle tissue, leading to stiffness, pain, and impaired function. This condition often arises following muscle paralysis due to various neuromuscular disorders, trauma, or prolonged immobilization. The calcification process can result in the formation of ossified tissue, which may further complicate muscle function and mobility. Patients may present with muscle weakness, limited range of motion, and discomfort in the affected area. Diagnosis typically involves imaging studies such as X-rays or MRI to visualize calcifications and assess the extent of muscle involvement. Treatment may include physical therapy, pain management, and in some cases, surgical intervention to remove calcified tissue. Understanding the underlying cause of paralysis is crucial for effective management and rehabilitation.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of muscle pathology and neuromuscular conditions.
  • Differentiation from other muscle disorders can be challenging.
  • Documentation must specify the affected muscle and side.
  • Potential for co-morbid conditions that complicate coding.

Audit Risk Factors

  • Inadequate documentation of the underlying cause of paralysis.
  • Failure to specify the affected muscle group.
  • Lack of imaging studies to support diagnosis.
  • Incorrect coding of associated conditions.
