Code Description

ICD-10 M61.349 is a billable code used to indicate a diagnosis of calcification and ossification of muscles associated with burns, unspecified hand.

Key Diagnostic Point:

Calcification and ossification of muscles associated with burns is a condition that arises when muscle tissue undergoes abnormal mineralization following thermal injury. This process can lead to stiffness, pain, and functional impairment of the affected muscles, particularly in the hand, which is crucial for daily activities. The calcification occurs as a response to the inflammatory process initiated by the burn injury, where the damaged muscle tissue may begin to heal abnormally, leading to the deposition of calcium salts. This condition can result in myositis, characterized by inflammation of the muscle, and may contribute to muscle weakness and reduced mobility. Patients may experience symptoms such as localized pain, swelling, and decreased range of motion, which can significantly impact their quality of life. The unspecified nature of the hand in this code indicates that the specific location of the calcification within the hand is not detailed, which can complicate treatment and rehabilitation efforts. Accurate coding is essential for appropriate management and reimbursement, as well as for tracking the incidence of this condition in clinical practice.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of burn severity and location
  • Need for precise identification of muscle involvement
  • Differentiation from other muscle disorders
  • Potential for co-existing conditions affecting coding

Audit Risk Factors

  • Inadequate documentation of burn severity
  • Failure to specify the exact muscle group affected
  • Lack of evidence for the association between burns and calcification
  • Misinterpretation of muscle weakness as a primary diagnosis

Specialty Focus

Medical Specialties

Physical Medicine and Rehabilitation

Documentation Requirements

Detailed documentation of muscle function, range of motion, and impact on daily activities.

Common Clinical Scenarios

Rehabilitation following burn injuries, assessment of muscle strength and function post-burn.

Billing Considerations

Consideration of multidisciplinary approaches for rehabilitation and the need for ongoing assessment of muscle recovery.

Orthopedic Surgery

Documentation Requirements

Comprehensive surgical notes detailing the procedure, muscle involvement, and post-operative care.

Common Clinical Scenarios

Surgical intervention for severe calcification or ossification affecting mobility.

Billing Considerations

Documentation must clearly outline the surgical rationale and expected outcomes to support coding.

Coding Guidelines

Inclusion Criteria

Use M61.349 When
  • According to the official ICD
  • 10 coding guidelines, this code should be used when there is clear documentation of calcification and ossification of muscles specifically associated with burns
  • It is important to ensure that the documentation supports the diagnosis and that the condition is directly linked to the burn injury

Exclusion Criteria

Do NOT use M61.349 When
  • Exclusion criteria include conditions not directly related to burns or those that do not involve muscle calcification
