Code Description

ICD-10 O22.20 is a billable code used to indicate a diagnosis of superficial thrombophlebitis in pregnancy, unspecified trimester.

Key Diagnostic Point:

Superficial thrombophlebitis is a condition characterized by inflammation of a superficial vein, often accompanied by thrombosis. In pregnancy, the risk of venous complications, including superficial thrombophlebitis, increases due to physiological changes such as increased blood volume, hormonal influences, and venous stasis. This condition can manifest as localized pain, tenderness, and redness along the affected vein, typically in the lower extremities. The diagnosis is often made clinically, but imaging may be utilized to rule out deep vein thrombosis (DVT). Management may include conservative measures such as elevation of the affected limb, warm compresses, and in some cases, anticoagulation therapy. It is crucial to monitor for potential complications, including the risk of thromboembolic events, which can pose significant risks to both the mother and fetus. Accurate coding of this condition is essential for appropriate management and reimbursement.

Complexity Factors

  • Differentiating between superficial and deep vein thrombosis.
  • Understanding the implications of anticoagulation therapy during pregnancy.
  • Recognizing the varying presentations of venous complications.
  • Navigating documentation requirements for obstetric conditions.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Failure to specify the trimester of pregnancy.
  • Misclassification of superficial thrombophlebitis as deep vein thrombosis.
  • Lack of follow-up documentation regarding treatment and outcomes.
