Code Description

ICD-10 M61.212 is a billable code used to indicate a diagnosis of paralytic calcification and ossification of muscle, left shoulder.

Key Diagnostic Point:

Paralytic calcification and ossification of muscle, particularly in the left shoulder, 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 causes, including neurological disorders, trauma, or prolonged immobilization. The calcification process can result in the formation of ossified tissue, which can further complicate muscle function and lead to significant disability. Clinically, patients may present with symptoms such as localized pain, swelling, and decreased range of motion in the affected shoulder. Diagnosis typically involves imaging studies, such as X-rays or MRI, to visualize the calcified areas and assess the extent of muscle involvement. Treatment may include physical therapy, pain management, and in some cases, surgical intervention to remove the calcified tissue. Understanding the underlying cause of the 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 types of muscle calcification.
  • Need for precise documentation of the affected area (left shoulder).
  • Potential overlap with other musculoskeletal codes.

Audit Risk Factors

  • Inadequate documentation of the paralysis history.
  • Failure to specify the affected muscle group.
  • Misclassification of the condition as a different type of calcification.
  • Lack of imaging documentation to support the diagnosis.

Coding Guidelines

Inclusion Criteria

Use M61.212 When
  • According to ICD
  • 10 coding guidelines, M61
  • 212 should be used when there is clear documentation of paralytic calcification and ossification specifically in the left shoulder
  • It is important to ensure that the condition is not due to other causes of calcification, such as metabolic disorders

Exclusion Criteria

Do NOT use M61.212 When
No specific exclusions found.

Arthrocentesis, aspiration and/or injection into a major joint or bursa.

Clinical Scenario

Used when a patient with calcification in the shoulder requires aspiration of fluid or injection for pain management.

Documentation Requirements

Document the indication for the procedure, including imaging results and patient symptoms.

Specialty Considerations

Orthopedic specialists should ensure that the procedure is justified based on the patient's condition.
