Code Description

ICD-10 M61.241 is a billable code used to indicate a diagnosis of paralytic calcification and ossification of muscle, right hand.

Key Diagnostic Point:

Paralytic calcification and ossification of muscle, particularly in the right hand, is a condition characterized by the abnormal deposition of calcium salts in muscle tissue, leading to stiffness, pain, and reduced mobility. This condition often arises following muscle paralysis due to various underlying neuromuscular disorders, trauma, or prolonged immobilization. The calcification process can result in the formation of ossified structures within the muscle, further complicating the clinical picture. 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 the calcified areas, alongside a thorough clinical evaluation to assess muscle function and strength. Treatment may include physical therapy, pain management, and in some cases, surgical intervention to remove calcified deposits. Understanding the etiology and progression of this condition 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 clearly specify the affected area and nature of the condition.
  • Potential for co-morbid conditions that may complicate coding.

Audit Risk Factors

  • Inadequate documentation of the clinical findings.
  • Failure to specify the affected muscle group.
  • Lack of imaging studies to support the diagnosis.
  • Misinterpretation of calcification versus ossification.
