Code Description

ICD-10 M22.01 is a billable code used to indicate a diagnosis of recurrent dislocation of patella, right knee.

Key Diagnostic Point:

Recurrent dislocation of the patella is a condition characterized by the repeated displacement of the kneecap (patella) from its normal position in the knee joint. This condition often results from underlying structural abnormalities, such as malalignment of the patella, ligament laxity, or previous injuries. Patients typically present with episodes of the patella dislocating, which can occur during activities such as running, jumping, or squatting. Symptoms may include pain, swelling, and a feeling of instability in the knee. The recurrent nature of the dislocation can lead to chronic pain and functional impairment, necessitating a thorough evaluation and management plan. Treatment options may include physical therapy, bracing, and in some cases, surgical intervention to stabilize the patella and repair any associated ligament or meniscal injuries. Arthroscopic procedures are often utilized to address these issues, allowing for minimally invasive access to the joint for repair and stabilization.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic dislocations
  • Identifying associated injuries such as meniscal tears or ligament damage
  • Understanding the implications of previous surgical history
  • Documenting the frequency and severity of dislocations

Audit Risk Factors

  • Inadequate documentation of recurrent episodes
  • Failure to document associated injuries such as meniscal tears
  • Misclassification of the type of dislocation (acute vs. recurrent)
  • Lack of clarity in treatment plans and outcomes

Arthroscopy, knee, surgical; with reconstruction of anterior cruciate ligament

Clinical Scenario

Used in cases where recurrent dislocation is associated with ACL injury.

Documentation Requirements

Document the indication for surgery, findings during arthroscopy, and any repairs performed.

Specialty Considerations

Orthopedic surgeons must ensure that the surgical report clearly outlines the relationship between the dislocation and any ligamentous injuries.

Frequently Asked Questions

What is the difference between M22.01 and S83.0XXA?

M22.01 refers specifically to recurrent dislocation of the patella, while S83.0XXA is used for acute dislocations. Accurate coding depends on the patient's history and the nature of the dislocation.
