Code Description

ICD-10 M66.141 is a billable code used to indicate a diagnosis of rupture of synovium, right hand.

Key Diagnostic Point:

Rupture of the synovium in the right hand refers to the tearing of the synovial membrane, which lines the joints and tendon sheaths. This condition can occur due to trauma, repetitive strain, or underlying inflammatory conditions such as rheumatoid arthritis. The synovium plays a crucial role in joint health by producing synovial fluid, which lubricates the joints and nourishes the cartilage. When the synovium ruptures, it can lead to pain, swelling, and decreased range of motion in the affected hand. Patients may present with localized tenderness, warmth, and effusion in the joint area. Diagnosis typically involves a thorough clinical examination and may be supported by imaging studies such as ultrasound or MRI to assess the extent of the rupture and any associated tendon injuries. Treatment options vary based on the severity of the rupture and may include conservative management with rest, splinting, and anti-inflammatory medications, or surgical intervention to repair the synovium and any damaged tendons. Rehabilitation is often necessary to restore function and strength to the hand following treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between synovial rupture and other soft tissue injuries
  • Need for precise documentation of the location and extent of the rupture
  • Potential for associated tendon injuries that require additional coding
  • Variability in treatment approaches based on severity and patient history

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the exact location of the rupture
  • Lack of imaging results to support the diagnosis
  • Inconsistent coding of associated tendon injuries
