Code Description

ICD-10 M61.24 is a billable code used to indicate a diagnosis of paralytic calcification and ossification of muscle, hand.

Key Diagnostic Point:

Paralytic calcification and ossification of muscle, particularly in the hand, 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 structures within the muscle, further complicating mobility and function. Patients may present with muscle weakness, limited range of motion, and discomfort in the affected area. The hand, being a highly functional part of the body, is particularly affected, leading to significant challenges in daily activities. 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 neuromuscular conditions contributing to this disorder is crucial for effective management and rehabilitation.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of neuromuscular disorders and their implications.
  • Differentiation from other muscle disorders can be challenging.
  • Documentation must clearly indicate the relationship between paralysis and calcification.
  • Need for precise anatomical localization (hand) in coding.

Audit Risk Factors

  • Inadequate documentation linking paralysis to calcification.
  • Failure to specify the affected muscle group.
  • Misinterpretation of imaging results leading to incorrect coding.
  • Inconsistent use of terminology in clinical notes.

Frequently Asked Questions

What is the primary cause of paralytic calcification?

Paralytic calcification is primarily caused by immobilization or paralysis of muscles, often due to neurological conditions, trauma, or prolonged inactivity.
