Code Description

ICD-10 M66.14 is a billable code used to indicate a diagnosis of rupture of synovium, hand and fingers.

Key Diagnostic Point:

Rupture of the synovium in the hand and fingers is a condition characterized by the tearing of the synovial membrane, which lines the joints and tendon sheaths. This injury can occur due to trauma, repetitive stress, 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 fingers or hand. Patients may present with symptoms such as localized tenderness, swelling, and sometimes a palpable defect in the area of the rupture. 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 injury. Treatment options vary based on the severity of the rupture and may include conservative management with rest and splinting, corticosteroid injections, or surgical intervention to repair the synovium and restore function.

Medium Complexity

Complexity Factors

  • Differentiation between traumatic and non-traumatic causes
  • Need for detailed documentation of symptoms and clinical findings
  • Potential for co-existing conditions affecting treatment
  • Variability in treatment approaches based on severity

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the exact location of the rupture
  • Lack of imaging results in the medical record
  • Inconsistent coding of co-existing conditions
