Code Description

ICD-10 M21.222 is a billable code used to indicate a diagnosis of flexion deformity, left elbow.

Key Diagnostic Point:

Flexion deformity of the left elbow refers to a condition where the elbow joint is unable to fully extend, resulting in a fixed position of flexion. This acquired deformity can arise from various causes, including trauma, neurological conditions, or prolonged immobilization. Patients may experience functional limitations, affecting their ability to perform daily activities such as reaching, lifting, or even dressing. The severity of the deformity can vary, with some individuals having a mild restriction while others may have significant impairment. Treatment options often include physical therapy, splinting, and in some cases, surgical intervention to correct the deformity and restore function. Understanding the underlying cause is crucial for effective management and rehabilitation. Accurate coding is essential for appropriate reimbursement and to reflect the complexity of the patient's condition in medical records.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in underlying causes (e.g., trauma, neurological disorders)
  • Need for detailed documentation of functional limitations
  • Potential for co-existing conditions affecting the elbow
  • Variations in treatment approaches and outcomes

Audit Risk Factors

  • Inadequate documentation of the functional impact of the deformity
  • Failure to specify the laterality of the condition
  • Lack of supporting evidence for the diagnosis (e.g., imaging studies)
  • Misclassification of the deformity type
