Code Description

ICD-10 M22.02 is a billable code used to indicate a diagnosis of recurrent dislocation of patella, left 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 arises due to underlying structural abnormalities, such as malalignment of the patella, ligamentous laxity, or previous injuries to the knee. Patients typically present with episodes of the patella dislocating, which may occur during physical activities or even at rest. Symptoms include pain, swelling, and a sensation of instability in the knee. The left knee is specifically affected in this code, which is crucial for accurate diagnosis and treatment planning. Internal derangements, such as meniscal tears or ligament injuries, can accompany recurrent dislocations, complicating the clinical picture. Arthroscopic procedures may be indicated for both diagnosis and treatment, allowing for direct visualization and repair of any associated injuries, such as lateral release or reconstruction of the medial patellofemoral ligament. Proper coding requires a thorough understanding of the patient's history and any concurrent knee injuries to ensure comprehensive care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between recurrent and first-time dislocations
  • Identifying associated injuries (e.g., meniscal tears, ligament injuries)
  • Understanding the implications of surgical interventions
  • Documenting the specific knee affected (left vs. right)

Audit Risk Factors

  • Inadequate documentation of recurrent episodes
  • Failure to document associated injuries
  • Incorrect coding of the affected knee
  • Lack of clarity on the treatment plan (surgical vs. conservative)

Frequently Asked Questions

What is the difference between M22.01 and M22.02?

M22.01 refers to recurrent dislocation of the patella in the right knee, while M22.02 specifies the left knee. Accurate coding is essential for treatment planning and insurance reimbursement.
